What is SDK ransomware?

While investigating new submissions to VirusTotal, our researchers discovered the SDK ransomware. This malicious program is part of the Phobos ransomware family.

After we executed a sample of SDK ransomware on our testing system, it encrypted files and altered their filenames. Original titles were appended with a unique ID assigned to the victim, the cyber criminals' email address, and a ".SDK" extension. To elaborate, a file initially named "1.jpg" appeared as "1.jpg.id[9ECFA84E-3449].[sdk@africamail.com].SDK".

Once this process was completed, the ransomware created ransom notes in a pop-up window ("info.hta") and text file ("info.txt").
