Windows Users have been given a two-week “window of opportunity” to get protected from a nasty malware duo, after UK authorities teamed up with international police to take control of hackers’ command and control servers.
Users are being told to take “immediate” action to protect their computers after US authorities seized a major criminal network. The FBI, working with the NCA, has taken control of a botnet used to steal personal and financial data.
Operation Tovar, as it’s been dubbed, shut down the Servers behind CryptoLocker and GameoverZeus, which are normally spread via dodgy email attachments or phishing emails. The two work together, with CryptoLocker taking over if the latter can’t find enough data to harvest and sell.
Once installed on a victim’s machine, Gameover Zeus will search specifically for files containing financial information.
If it cannot find anything it deems of worth, some strains of Gameover Zeus will then install Cryptolocker – a ransomware program that locks a person’s machine until a fee is paid.
