SIGMA is a ransomware-type virus discovered by malware security researcher, Michael Gillespie. This high-risk malware is distributed using spam emails that contain a message stating that users will be charged $3000+ from their MasterCard, unless they open a MS Office document attached.

After opening this attachment and entering the password provided, users will inadvertently execute configured macros, which will then immediately perform a number of actions to download and run SIGMA ransomware.

Once infiltrated, this virus encrypts stored data using RSA-2048 cryptography and appends four random letters/digits to the name of each encrypted file (e.g., "sample.jpg" might be renamed to a filename such as "sample.jpg.Ka8E"). Immediately after encryption, SIGMA changes the desktop wallpaper and places two files ("ReadMe.html" and "ReadMe.txt") on the desktop.
