(The Hosting News) – Security firm Symantec has pulled off a feat against the threat of botnets.
The company recently announced that it had disabled 500 thousand infected computer systems responsible for the ZeroAccess botnet, according to a report from the BBC on Tuesday.
Despite pulling them offline, the 500 thousand number represents just a portion of the botnet’s infected network – computers that initially included as many as 1.9 million.
The botnet has been responsible for things like online currency (bitcoin) and advertising fraud.
“We’ve taken almost a quarter of the botnet offline,” stated Symantec security operations manager Orla Cox in the BBC report.
“Whenever a computer becomes infected with ZeroAccess, it first reaches out to a number of its peers to exchange details about other peers in its known P2P network. This way, bots become aware of other peers and can propagate instructions and files throughout the network quickly and efficiently. In the ZeroAccess botnet, there is constant communication between peers. Each peer continuously connects with other peers to exchange peer lists and check for updated files, making it highly resistant to any take-down attempts,” commented Symantec via its blog.
Earlier this year in June, tech giant Microsoft announced that it had shut down Citadel malware botnets.
