New ransomware variant encrypts individual files with unique key

A new variant of ransomware encrypts files using a unique key for each individual file, but this may not be as threatening as it seems, according to SC Magazine.

Jakub Kroustek, a malware analyst and reverse engineer with Avast, disclosed the new ransomware called CryPy. According to cybersecurity analysts, CryPy may not be as sophisticated as it seems because using a unique key for each encrypted file is actually a disadvantage. Steve McGregory, director of application and threat intelligence at Ixia, told SC Magazine that blocking "the source of this malicious IP address" would shut the threat down.

CryPy is written in Python, and incidents involving Python malware are on the rise, the report notes.
