Cryptowall 4: A Better Mousetrap (But We Are The Mice)

The sociopathic cretins who code and deploy the Cryptowall ransomware have upped the ante yet again with a few "improvements" to their product.
Andra Zaharia of Denmark-based Heimdal Security says Cryptowall 4.0 is employing "vastly improved" communications and better code, so it can exloit more vulnerabilities.
"Cryptowall 4.0 still includes advanced malware dropper mechanisms to avoid antivirus detection, but this new version possesses vastly improved communication capabilities," Zaharia says
"It includes a modified protocol that enables it to avoid being detected, even by second generation enterprise firewall solutions.
"This lowers detection rates significantly compared to the already successful Cryptowall 3.0 attacks."
