SamSam Ransomware – Infection Methods

For this version of SamSam ransomware to infect unsuspecting users, it may take advantage of various different types of methods for infection. These can be divided in proactive and passive infection approaches and the proactive ones involve a variant of SamSam ransomware that may be sent to victims via e-mail. Such e-mails often pretend as if they come from large companies, from the likes of PayPal, eBay, Amazon or other big names in order to get the victim to bite. Here is one example of a carefully designed fake e-mail:

Furthermore, SamSam can be passively waiting for you to download it’s infection file by looking for files on suspicious software-providing websites. Those files are usually the following:

  • Fake setups of programs.
  • Fake game patches or cracks.
  • Fraudulent software license activators.
  • Fake keygens.

SamSam Ransomware – Malicious Activity

Samas ransomware, also known as SamSam as many refer it, was the reason of multiple reports that it has infected major government institutions in the city of Atlanta, Georgia. The ransomware infection aims to encrypt the files on the computers of victims and then drop it’s payload files. The payload of SamSam consists of different types of files and malware, which many refer to as PsExec. The difference between a traditional ransomware virus and the SamSam infection is that SamSam is a combination of several different types of infections. This allows SamSam ransomware to firstly drop a pentesting file in order to initiate a detection-less infection. Such pentesting gives the ability of cyber-criminals to see what types of vulnerabilities on the victim’s computer are unpatched and attack them via the exploit kit the virus uses. Once a weakness is discovered, the psexec.exe file is used in order to exploit the particular vulnerability selected via a JavaScript or an RDP (Remote Desktop Protocol).

The SamSam ransomware also has elements taken from the following viruses:

  • Derusbi infostealer.
  • Bladabindi infostealer for stealing credentials.
  • PsExect in order to execute programs remotely.

These tools are all used on your computer after it has been infected by SamSam ransomware. The first activity of the ransomware is to run a command as an administrator on the victim’s computer that will make sure the shadow volume copies in Windows are deleted and restoring your files via backup is impossible:

→ C:\Windows\System32\cmd.exe” /C vssadmin.exe Delete Shadows /All /Quiet

In addition to this, the ransomware also makes sure to schedule it’s ransom note for automatically appearing on your computer. The ransom note of the latest variant of the malware, has been reported to appear like the following:

.weapologize SamSam Ransomware – Encryption Process

The encryption algorithm used to encipher the files on your computer by this virus is RSA cipher which is a part of the Suite.B category of encryption. It is often used by governments in order to hide top-secret files by encrypting them. The algorithm is specific by the fact that it creates different decryption keys for each file. The SamSam ransomware’s latest variant uses the .weapologize file extension for the file encryption process. The process of encrypting files, used by SamSam can be characterized via the following chain of activities in the figure below:

The virus is careful not to encrypt files in %SystemDrive% that are essential for the functioning of Windows, so that it won’t break your PC after infection.
