Trojan malware has been found to be controlling Google ad space by sending users to different websites when they try to click on the search engine’s advertisements.
Romanian-based online security firm BitDefender found the hidden software, Trojan.Qhost.WU, and said that the threat could have a negative impact on both users and businesses.
Attila-Mihaly Balazs, a BitDefender virus analyst, said that users are prone to clicking on links or ads that “may contain malicious code”, while he said webmasters are affected because their valuable ad space is stolen by a third-party vendor and are used to promote someone else’s website.
An anonymous hacker who told siliconrepublic.com about how the malware could be operating said “most anti-virus” programs should pick up on the problem if “if an attempt was made to modify the host file anyway”.
