CryptoWall

CryptoWall is a ransomware family referenced in the provided content as one of the major cryptomalware strains active during the mid-2010s. It is described as a copycat family in relation to CryptoLocker, but also as a major ransomware threat in its own right and part of the global surge in cryptomalware observed from mid-2014 onward. The content associates CryptoWall with file-encrypting ransomware activity and notes that, like CryptoLocker, it used unique Tor hidden service Bitcoin payment domains. CryptoWall is cited alongside other prominent ransomware families including CryptoDefense, Locky, Cerber, TeslaCrypt, CTB-Locker, GandCrab, and Magniber.

The content links CryptoWall to exploit-kit-driven delivery, specifically stating that Magnitude Exploit Kit has been known to drop CryptoWall, along with Locky, Cerber, Magniber, and GandCrab. It is also referenced in broader reporting on ransomware botnet/controller activity and malware trends. No specific threat actor is directly attributed as the developer or operator of CryptoWall in the provided material, but the malware is mentioned in contexts involving large-scale ransomware distribution ecosystems.

High-confidence behavioral details in the content are limited, but CryptoWall is consistently characterized as ransomware/cryptomalware that encrypts victim data and demands Bitcoin payment via Tor-based infrastructure. No specific industries, platforms, hashes, domains, wallet addresses, or other unique indicators of compromise are provided for CryptoWall itself in the supplied content.
