Anatomy of a personalized Cerber spam

Last week I was browsing Twitter when I found a tweet from Jaromir Horejsi about a spam mail with a Locky downloader that was personalized with his surname. It was the same day that I received a spam too, also with my surname in it. I’m always happy when this happens as it gives me an opportunity to go down the rabbit hole and check what’s hidden in there.

In my case the mail body was empty. It only contained a ZIP attachment and was sent with high priority.

cerber-spamMy surname (or a substring of it) was part of the sender address, the subject and also the ZIP file name. The content of the ZIP file was a single JSE file. JSE stands for JavaScript Encoded Script File and it is exactly what its name indicates, a JavaScript file encoded into a binary blob that can be executed the same way as “normal” JavaScript files. The file contained a lot of random text comments at the beginning and at the end with a single line encoded binary blob in between.

cerber-jse-downloader

JSE files are frequently used in recent spam campaigns. The reason probably is that AV engines are less likely to detect such encoded files as opposed to JS files in a textual form. It also adds an additional (albeit simple) layer of obfuscation. At this stage, I already knew that this file will only be a simple downloader, however I decided to decode the blob and get the original JS file just for fun and practice. After googling around I eventually found a VBS script that can decode both VBE and JSE files. As I expected, the decoded JS file was just another slightly obfuscated JavaScript downloader, very similar to that of Locky from my previous post. I did not try to deobfuscate the file as it should be pretty straightforward, you can find it here however, in case you would like to compare the detection rate for both encoded and decoded variants. Please do not make the mistake to draw any conclusion from the number of AV engines detecting these files. Remember that AV engines can have a lot of detection features that are not included in VirusTotal.

Having the original decoded JavaScript downloader, I executed it to see what download URL was used and to get the payload. The download URL for this script was http://somefeelg.top/admin.php?f=1.bin.

cerber-dropper-url

I cycled through the same URL several times, incrementing the number by one every time. It served me a PE file every time up until 8.bin. I managed to get two unique PE files this way. The first one was already on VT by the time I downloaded, the second one however was not so I decided to take a look at that one.

In most cases I start my payload analysis by simply executing the sample. This can happen either in a VM, in a sandbox or both. By running the sample, I quickly realized that the payload was not Locky as I initially expected but the Cerber ransomware, asking for 1 bitcoin to decrypt my files.

cerber-cerber

cerber-bitcoin

I also noticed an interesting behavior. When running the sample, I received an elevation prompt for cmd.exe but after displaying the details it was imminent that the command line interpret was only executing the malware sample with the command line argument -eval.

cerber-runas

This is not a very clever way to gain elevation but I understand it could fool a lot of user to click the Yes button as they will only see the Windows Command Processor name until they click on the details button.

Now was the time to take a closer look at the sample. I opened it in CFF Explorer and saw that it is an NSIS (Nullsoft Scriptable Install System) file. NSIS is a popular installer framework. Unfortunately, it is also widely used as an additional obfuscation layer for malware. Fortinet recently reported that Locky started to use NSIS in some cases as its loader. The NSIS framework as you might have already guessed by now is scriptable. You can control the installation with an NSIS Script File (.nsi) that is compiled into a binary format and executed by the NSIS engine. You can extract the content of the file with 7-Zip.

cerber-nsis

Unfortunately, 7-Zip will not extract the script file (at least not the most recent version). I used the NSIDis (Nullsoft Decompiler) project recommended by the NSIS Wiki to extract and decompile the installation script. I had to fix some typos in the Python script to get it work but it should not be any problem for anybody with basic programming skills. The decompiled script contains a lot of junk and the most important part is just the following few lines of code (I edited the script for better reading).

cerber-script-nsi

The script only does two things. It first concatenates vicarages.rxy and heresiarch.rnk into a third file named Introvert.K. Then it loads ProxySettings.dll and calls the method called Mawkin. The next thing to look into was ProxySettings.dll.

The DLL is really simple and there is nothing suspicious at first sight. It does not contain any method named Mawkin, the relevant code is called from the entry point. After a while, the true intention of the DLL started to appear on the stack.

cerber-decrypted-func

These are functions used in RunPE injection (or process hollowing). The names are decrypted on the fly and function addresses are resolved dynamically. It was obvious that ProxySettings.dll was only an injector library that would inject the real payload into a newly spawned process. The payload was contained encrypted in Introvert.K loaded from ProxySettings.dll.

cerber-payload-open

cerber-payload-read2

cerber-payload-read3

I had no time to analyze the decryption routine and frankly I was more interested in the payload so I jumped right to the injection itself. The DLL was spawning the process of the NSIS installer to inject the payload.

cerber-suspended-spawn

I just had to wait for the first inject to get the address of the decrypted payload in memory.

cerber-pe-inject4

cerber-pe-inject3

I was able to dump the decrypted payload which at this point I already knew was a Cerber sample.

Check Point released an excellent detailed report on Cerber recently that I encourage everybody to read. As I had not much time, I only tried to check if parts from this report are still valid for my payload. I expected some differences as the report is valid for Cerber 2. My payload however was Cerber 3 as it was creating .cerber3 extensions for encrypted files. First thing I wanted to check was the elevation dialog I saw and indeed, the payload contains the code to elevate through calling ShellExecuteEx windows API.

cerber-shellexecute

It uses the verb runas to force the spawned cmd.exe to run elevated. The command prompt executable will then run the malware with -eval argument on the command line. As cmd.exe is already elevated, the executed malware would run elevated too. Cerber really tries hard to elevate. If you click on the No button in the elevation dialog, it will prompt you 2 more times with 1 minute sleeps between the prompts. The Check Point report has a detailed description of different modes that Cerber supports. Among them is also the EVAL mode that uses the command line argument -eval. In my case however, there was no PID passed as a parameter to -eval and throughout my tests I did not feel any difference between executing the malware with or without this argument. I feel like in the previous version this argument was only to signal to the newly spawned malware process that it should not try to elevate again because everything was done in order to do that (with or without success). My testing Windows 7 had the EnableLua flag set in the registry and the sample kept trying to elevate through runas when executed. The only thing that had effect on execution was if the sample was executed as elevated, no matter if I passed the -eval argument or not.

One of the clear differences between the behavior of Cerber 2 from the report and my Cerber 3 payload was the way how it tried to delete the shadow volume copy. According to Check Point, Cerber 2 was using vssadmin.exe to do that. The sample I got was using wmic.exe. This is not a new technique, several ransomware families are using it already. The reason behind this technique is that executing vssadmin.exe immediately raises an alert in most of the AV applications. Cerber is executing wmic.exe in a stealthy way by first spawning cmd.exe on the background

cerber-cmdspawn

and sending commands to it through the WriteFile API.

cerber-writefile

It even has code to check the result of the operation by reading the console output with ReadFile API and log the output through the OutputDebugString API as the command line window is not visible.

cerber-readconsole

It is important to note here that (according to my tests) this sample was not trying to delete volume shadow copy if not running as elevated. This is very interesting as in my case the UAC bypass was not working at all and the runas elevation is much more noisy and more importantly it does require user approval.

I already mentioned that this sample has some calls to OutputDebugString. The author had no intention to remove the debugging code from the binary. You can even control it through the configuration. Cerber uses a JSON format for its configuration. It is (along with all strings) encrypted in the body of the malware and decrypted on the fly when needed. I changed the debug flag in the configuration to see what will be logged through OutputDebugString.

cerber-config

Unfortunately, it did not log too much apart from every file that was encrypted. It also saved the list of encrypted files into a file named files.txt. During the analysis I found that some failures are also logged in debug mode. I’m adding the pretty-printed JSON configuration here as a reference.

         <h3>What should you do with these addresses?</h3>
         <p>If you read the instructions in TXT format (if you have instruction in HTML (the file with an icon of your Internet browser) then the easiest way is to run it):</p>
         <ol>
         <li>take a look at the first address (in this case it is <span class="upd_off" id="upd_2">Please wait...</span><a class="url" href="http://{TOR}.{SITE_1}/{PC_ID}" id="url_2" target="_blank">http://{TOR}.{SITE_1}/{PC_ID}</a>);</li>
         <li>select it with the mouse cursor holding the left mouse button and moving the cursor to the right;</li>
         <li>release the left mouse button and press the right one;</li>
         <li>select "Copy" in the appeared menu;</li>
         <li>run your Internet browser (if you do not know what it is run the Internet Explorer);</li>
         <li>move the mouse cursor to the address bar of the browser (this is the place where the site address is written);</li>
         <li>click the right mouse button in the field where the site address is written;</li>
         <li>select the button "Insert" in the appeared menu;</li>
         <li>then you will see the address <span class="upd_off" id="upd_3">Please wait...</span><a class="url" href="http://{TOR}.{SITE_1}/{PC_ID}" id="url_3" target="_blank">http://{TOR}.{SITE_1}/{PC_ID}</a> appeared there;</li>
         <li>press ENTER;</li>
         <li>the site should be loaded; if it is not loaded repeat the same instructions with the second address and continue until the last address if falling.</li>
         </ol>
         <p>If for some reason the site cannot be opened check the connection to the Internet; if the site still cannot be opened take a look at the instructions on omitting the point about working with the addresses in the HTML instructions.</p>
         <p>If you browse the instructions in HTML format:</p>
         <ol>
         <li>click the left mouse button on the first address (in this case it is <span class="upd_off" id="upd_4">Please wait...</span><a class="url" href="http://{TOR}.{SITE_1}/{PC_ID}" id="url_4" target="_blank">http://{TOR}.{SITE_1}/{PC_ID}</a>);</li>
         <li>in a new tab or window of your web browser the site should be loaded; if it is not loaded repeat the same instructions with the second address and continue until the last address.</li>

         <p>If for some reason the site cannot be opened check the connection to the Internet.</p>

         <p>Unfortunately these sites are short-term since the antivirus companies are interested in you do not have a chance to restore your files but continue to buy their products.</p>
         <p>Unlike them we are ready to help you always.</p>
         <p>If you need our help but the temporary sites are not available:</p>
         <ol>
         <li>run your Internet browser (if you do not know what it is run the Internet Explorer);</li>
         <li>enter or copy the address <a href="https://www.torproject.org/download/download-easy.html.en" target="_blank">https://www.torproject.org/download/download-easy.html.en</a> into the address bar of your browser and press ENTER;</li>
         <li>wait for the site loading;</li>
         <li>on the site you will be offered to download Tor Browser; download and run it, follow the installation instructions, wait until the installation is completed;</li>
         <li>run Tor Browser;</li>
         <li>connect with the button "Connect" (if you use the English version);</li>
         <li>a normal Internet browser window will be opened after the initialization;</li>
         <li>type or copy the address <span class="tor">http://{TOR}.onion/{PC_ID}</span> in this browser address bar;</li>

         <p>If TOR address is not available for a long period (2-3 days) it means you are late; usually you have about 2-3 weeks after reading the instructions to restore your files.</p>
         <hr>
         <h3>Additional information:</h3>
         <p>You will find the instructions for restoring your files in those folders where you have your encrypted files only.</p>
         <p>The instructions are made in two file formats - HTML and TXT for your convenience.</p>
         <p>Unfortunately antivirus companies cannot protect or restore your files but they can make the situation worse removing the instructions how to restore your encrypted files.</p>
         <p>The instructions are not viruses; they have informative nature only, so any claims on the absence of any instruction files you can send to your antivirus company.</p>

  Cannot you find the files you need?
  Is the content of the files that you looked for not readable???
  
  It is normal because the files' names, as well as the data in your files
  have been encrypted.
  
  Great!
  You have turned to be a part of a big community "#Cerb3r Ransomware".
  
  
  #########################################################################
  
  
  !!!  If you are reading this message it means the software "Cerber" has
  !!!  been removed from your computer.
  
  !!!  HTML instruction ("# DECRYPT MY FILES #.html") always contains a
  !!!  working domain of your personal page!
  
  
  #########################################################################
  
  
  What is encryption?
  -------------------
  
  Encryption is a reversible modification of information for security
  reasons but providing full access to it for authorized users.
  
  To become an authorized user and keep the modification absolutely
  reversible (in other words to have a possibility to decrypt your files)
  you should have an individual private key.
  
  But not only it.
  
  It is required also to have the special decryption software
  (in your case "Cerber Decryptor" software) for safe and complete
  decryption of all your files and data.
  
  
  #########################################################################
  
  
  Everything is clear for me but what should I do?
  ------------------------------------------------
  
  The first step is reading these instructions to the end.
  
  Your files have been encrypted with the "Cerber Ransomware" software; the
  instructions ("# DECRYPT MY FILES #.html" and "# DECRYPT MY FILES #.txt")
  in the folders with your encrypted files are not viruses, they will
  help you.
  
  After reading this text the most part of people start searching in the
  Internet the words the "Cerber Ransomware" where they find a lot of
  ideas, recommendations and instructions.
  
  It is necessary to realize that we are the ones who closed the lock on
  your files and we are the only ones who have this secret key to
  open them.
  
  !!!  Any attempts to return your files with the third-party tools can
  !!!  be fatal for your encrypted files.
  
  The most part of the third-party software change data within the
  encrypted file to restore it but this causes damage to the files.
  
  Finally it will be impossible to decrypt your files.
  
  When you make a puzzle, but some items are lost, broken or not put in its
  place - the puzzle items will never match, the same way the third-party
  software will ruin your files completely and irreversibly.
  
  You should realize that any intervention of the third-party software to
  restore files encrypted with the "Cerber Ransomware" software may be
  fatal for your files.
  
  
  #########################################################################
  
  
  !!!  There are several plain steps to restore your files but if you do
  !!!  not follow them we will not be able to help you, and we will not try
  !!!  since you have read this warning already.
  
  
  #########################################################################
  
  
  For your information the software to decrypt your files (as well as the
  private key provided together) are paid products.
  
  After purchase of the software package you will be able to:
  
  1.  decrypt all your files;
  
  2.  work with your documents;
  
  3.  view your photos and other media;
  
  4.  continue your usual and comfortable work at the computer.
  
  If you understand all importance of the situation then we propose to you
  to go directly to your personal page where you will receive the complete
  instructions and guarantees to restore your files.

  What should you do with these addresses?
  ----------------------------------------
  
  If you read the instructions in TXT format (if you have instruction in
  HTML (the file with an icon of your Internet browser) then the easiest
  way is to run it):
  
  1.  take a look at the first address (in this case it is
      http://{TOR}.{SITE_1}/{PC_ID});
  
  2.  select it with the mouse cursor holding the left mouse button and
      moving the cursor to the right;
  
  3.  release the left mouse button and press the right one;
  
  4.  select "Copy" in the appeared menu;
  
  5.  run your Internet browser (if you do not know what it is run the
      Internet Explorer);
  
  6.  move the mouse cursor to the address bar of the browser (this is the
      place where the site address is written);
  
  7.  click the right mouse button in the field where the site address
      is written;
  
  8.  select the button "Insert" in the appeared menu;
  
  9.  then you will see the address
      http://{TOR}.{SITE_1}/{PC_ID}
      appeared there;
  
  10. press ENTER;
  
  11. the site should be loaded; if it is not loaded repeat the same
      instructions with the second address and continue until the last
      address if falling.
  
  If for some reason the site cannot be opened check the connection to the
  Internet; if the site still cannot be opened take a look at the
  instructions on omitting the point about working with the addresses in
  the HTML instructions.
  
  If you browse the instructions in HTML format:
  
  1.  click the left mouse button on the first address (in this case it is
      http://{TOR}.{SITE_1}/{PC_ID});
  
  2.  in a new tab or window of your web browser the site should be loaded;
      if it is not loaded repeat the same instructions with the second
      address and continue until the last address.
  
  If for some reason the site cannot be opened check the connection to
  the Internet.

  9.  press ENTER;
  
  10. the site should be loaded; if for some reason the site is not loading
      wait for a moment and try again.
  
  If you have any problems during installation or operation of Tor Browser,
  please, visit https://www.youtube.com/ and type request in the search bar
  "install tor browser windows" and you will find a lot of training videos
  about Tor Browser installation and operation.
  
  If TOR address is not available for a long period (2-3 days) it means you
  are late; usually you have about 2-3 weeks after reading the instructions
  to restore your files.

  Additional information:
  
  You will find the instructions for restoring your files in those folders
  where you have your encrypted files only.
  
  The instructions are made in two file formats - HTML and TXT for
  your convenience.
  
  Unfortunately antivirus companies cannot protect or restore your files
  but they can make the situation worse removing the instructions how to
  restore your encrypted files.
  
  The instructions are not viruses; they have informative nature only, so
  any claims on the absence of any instruction files you can send to your
  antivirus company.

The last thing I checked was the usage of synchronization objects. I quickly found the place where the sample was creating its main mutex.

cerber-mutex

This is the same mutex that is described in the Check Point report and as you can see Cerber will terminate execution if the mutex already exists in the system. It is however not the only synchronization object that is created. This sample also uses a named event.

cerber-createevent

The event serves as a synchronization object between non-elevated and elevated instances of Cerber. It is only created in the elevated process and it is only opened in the non-elevated one.

cerber-eventopen

As you can see, the sample is trying to open the event and if it fails, it is retrying every 1 millisecond for a whole minute. The 1 millisecond sleep is important, as the non-elevated sample has to terminate as soon as possible, so that the main mutex is destroyed, otherwise the elevated process would terminate because of that. If the event is successfully opened, the non-elevated process will terminate. In case it cannot open the event for a whole minute, it will go on with the encryption in non-elevated mode. The names of the synchronization objects are in a form of shell.{%GUID%} where the GUID part is derived from a string in a form %COMPUTERNAME%\CERBER_CORE_PROTECTION_MUTEX for the mutex and %COMPUTERNAME%\CERBER_EVALUATED_CORE_PROTECTION_EVENT for the event.

cerber-namegen

Conclusion:

We can see that Cerber is still evolving and the 3rd version of this ransomware contains minor modifications in implementation besides the change that was intended to fix the encryption. The changes in the elevation scheme and the usage of an additional synchronization object could serve as additional IOCs.

Also did I mention that the other sample I managed to download from the URL above was also an NSIS installer? And guess what the payload was … that’s right, it was Locky. By the way, it is still serving new and new droppers so be sure to check i out 😉

The fact that Cerber and Locky are using the same spreading mechanisms and even sharing the same domain for hosting the droppers could very well be the reason behind this too (remember the spam that I mentioned at the beginning?). But this is just a wild guess 🙂

Stay safe and until next time…

  1. Hello,

    My name is David Balaban, I run http://privacy-pc.com/ 

    I have put together this (hopefully) useful and convenient post: http://privacy-pc.com/articles/ransomware-chronicle.html

    It covers all new ransomware strains, updates, decryptors, etc. It is an ongoing list. I plan to update it on a weekly basis.

    It is based on BleepingComputer’s weekly ransomware articles contributed by you and other malware researchers. 

    Thanks for your work!

    Regards,

    – David Balaban
