Rewterz Threat Alert – New VCrypt Ransomware Locks Files in Password-Protected 7ZIPs
May 7, 2020
Rewterz Threat Advisory – CVE-2020-10732 – Linux Kernel information disclosure Vulnerability
May 8, 2020

Rewterz Threat Alert – ProLock RansomWare – IOCs

May 7, 2020

Severity

High

Analysis Summary

ProLock actors encrypt the files on the victim’s network using RSA-2048 algorithm. After encrypting a victim’s files, ProLock actors leave a .txt extension file as a ransom note on the victim computer. The ransom note instructs the victims to visit a TOR page and log in using a unique ID included in the ransom note. The TOR page then displays the ransom price and wallet address for the ransom payment. The ransom note indicates the decryption keys will be stored for one month. The ProLock actors provide an email address victims can use to contact the ProLock actors if the victim cannot connect to the TOR page.

Impact

File encryption
