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:

SamSam Ransomware – atividade maliciosa

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 (Protocolo área de trabalho remota).

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 Apagar Sombras / All / Quiet
