The Sirattacker and ALC ransomware families continue to gain traction and compromise Microsoft Windows devices.
Sirattacker is a variant of Chaos ransomware and is possibly distributed as an Ethereum mining application.
The malware gives the victim 72 hours to purchase the decryption key for $400.00US.
ALC ransomware creates several files on the infected desktop and displays a ransom note demanding $2000.00US for access to the locked files.
The malware does not actually encrypt files but acts more of a scareware to convince the victim to pay the ransom.
