After the MMM ransomware attacks your computer, the virus immediately begins to demand money to get them back by dropping a ransom note, named RESTORE_0x009d8a_FILES.html. In it, 1.2 BTC is requested from the victims to be sent over in order to get the encrypted files restored back to normal.

Update May 2018: Triple M ransomware has come out in a newer variant, using the .MMM file extension and asking to pay ransom in BitCoin.

Distribution of MMM Ransomware

Similar to over 80% of the newer ransomware viruses out there, the MMM ransomware infection may be widespread via multiple different types of methods, primary associated with malicious e-mail spam, also known as malspam. Such messages often portray the malicious file carrying the payload of MMM ransomware as a legitimate type of file. Such as:

  • Receipt.
  • Invoice.
  • Letter of complaint.
  • Letter of confirmation.
  • Suscpicious bank activity report.
  • Other urgent matters.

If the victim is tricked into actually opening the malicious file, he or she immediately becomes infected with MMM ransomware.

Besides via torrents, the malicious files of MMM ransomware may also exist as fake setups of software, fake key generators, game patches, cracks or other type of seemingly legitimate executable files.

MMM Ransomware – More Information

Once MMM ransowmare has already infected your computer system, the virus’s first signs of presence begin to show. It may temporarily freeze your computer during which it performs numerous activities on it. The first of those is to drop it’s malicious file which is a .exe file with a random A-Z and 0-9 name on your computer. The file may be accompanied by other malicious files that may be of the following types;

→ .tmp, .exe, .dll, .bat, .vbs, .cmd

These files may be scattered across different parts of your Windows, but they are primarily dropped in the following locations:

  • %AppData%
  • %Windows%
  • %Local%
  • %LocalLow%
  • %Temp%
  • %Roaming%

As soon as MMM ransomware drops it’s malicious files, it also creates it’s ransom note. The note is created so that the ransomware makes it’s presence known and motivates victims into contacting the e-mail [email protected] and pay the sum of 1.2 BTC to the address 151F8ufANwCohXzteZ2mauvHLvkS8WmEFT. The ransom note is named similar to RESTORE_0x009d8a_FILES.html and has the following message for the victims:

In addition to making sure it is noticed, the MMM ransomware virus may also delete the shadow volume copies on the computers it infects. This is achieved by executing the vssadmin and bcedit commands in a hidden manner, without the victim noticing them:

→ process call create “cmd.exe /c
vssadmin.exe delete shadows /all /quiet
bcdedit.exe /set {default} recoveryenabled no
bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures

In addition to this, the MMM ransomware virus may also heavily modify the Windows Registry Editor, creating various registry entries in the following sub-keys:

→ HKEY_CURRENT_USER\Control Panel\Desktop\
HKEY_USERS\.DEFAULT\Control Panel\Desktop\
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

MMM Ransomware The Encryption Process

The MMM ransowmare virus uses three types of encryption algorithms. The first one is called AES cipher (Advanced Encryption Algorithm) and it encrypts portion of the files themselves to generate unique asymmetric decryption key. Then, the virus uses the RSA (Rivest-Shamir Adleman) encryption to generate unique keys for each infection. And the HMAC is used to generate a unique hash and make decyrption even more confusing. The files targeted by MMM ransomware are reported to be the following:

“PNG .PSD .PSPIMAGE .TGA .THM .TIF .TIFF .YUV .AI .EPS .PS .SVG .INDD .PCT .PDF .XLR .XLS .XLSX .ACCDB .DB .DBF .MDB .PDB .SQL .APK .APP .BAT .CGI .COM .EXE .GADGET .JAR .PIF .WSF .DEM .GAM .NES .ROM .SAV CAD Files .DWG .DXF GIS Files .GPX .KML .KMZ .ASP .ASPX .CER .CFM .CSR .CSS .HTM .HTML .JS .JSP .PHP .RSS .XHTML.
