National Crime Agency issues warning over GOZeuS and CryptoLocker malware

The National Crime Agency (NCA) has issued an unprecedented warning over GOZeuS and CryptoLocker PC malware.

"Action taken by the NCA to combat the threat will give the UK public a unique, two-week opportunity to rid and safeguard themselves from two distinct but associated forms of malware known as GOZeuS and CryptoLocker," warned the NCA in a statement.

GOZeus - short for Gameover Zeus - is a peer-to-peer variant of the Zeus family of malware, first identified in September 2011. It is designed to steal bank log-in credentials by searching a compromised PC for files containing financial information. If it fails to find anything of value, it may then install Cryptolocker - "ransomware" that encrypts the PC's hard-disk drive, only providing the decryption key after a fee is paid.

GOZeus uses a decentralised infrastructure, which makes it more difficult to take down than a typical botnet, according to an advisory from the US Computer Emergency Readiness Team (US-CERT).

Very often, if GOZeus is thwarted, its controllers use their access to the PC to install CryptoLocker instead. This encrypts the contents of the PC's hard-disk drive and demands a ransom from the user to decrypt it.
