What is the asasin virus?

asasin virus is a term used to identify ransomware in the Locky family of malware that encrypts files using RSA-2048 and AES-128 cryptography ciphers, appends the .asasin file extension to the end of the file name, changes the file type, and downloads a ransom note on Windows Desktop and in every folder it encrypted files in. The ransomware will also download an image of the ransom note and change Windows Desktop background to the image and display the image in a new window.

Once the asasin virus has encrypted files and appended the .asasin extension it will download the ransom note and an image of the ransom note on Windows desktop and in folders it encrypted files in. The virus uses the ransom note to explain to victims of the virus what happened to their files and how to purcahse a decryption key and special tool to decrypt files the way that the malware authors want them to.

Like most ransomware infections, the asasin virus is typically spread by email spam messages that contain malicious 7zip, 7z, rar, and zip email attachments. Once the attachment is downloaded and executed it will spread the malware across the machine and begin its encryption process.

One particular email we found the sample in claims to be sent from a person named Brithney. The message said “yo” and “Hello my dear – I’ve had a web camera with good quality – write me – and I’ll do what you want for you, long time not seen you in a web camera. My email .” The attached .7zip extracted a .vbs file. When the .vbs file was executed the malware spread across the machine.
