Don’t Get Nineballed

According to the Washington Post yesterday there is a new kind of click fraud waiting to take out your unsuspecting users of internet search.


Slashdot says:

“The Trojan, dubbed FFsearcher by SecureWorks, was among the pieces of malware installed by sites hacked with the Nine-Ball mass compromise, which attacked some 40,000 Web sites this month. The Trojan takes advantage of Google's "AdSense for Search" API, which allows Web sites to embed Google search results alongside the usual Google AdSense ads. (SecureWorks' writeup indicates that Yahoo search is targeted too, but the researchers saw no evidence if the malware redirecting Yahoo searches.) While most search hijackers give themselves away on the victim's machine by redirecting the browser through some no-name search engine, FFsearcher "...converts every search a victim makes through, so that each query is invisibly redirected through the attackers' own Web sites, via Google's Custom Search API. Meanwhile, the Trojan manipulates the victim's PC and browser so that the victim never actually sees the attacker-controlled Web site that is hijacking the search, but instead sees the search results as though they were returned directly from (and with in the victim browser's address bar, not the address of the attacker controlled site). Adding to the stealth is the fact that search results themselves aren't altered by the attackers, who are merely going after the referral payments should victims click on any of the displayed ads. What's more, the attackers aren't diverting clicks or ad revenue away from advertisers or publishers, as in traditional click fraud: They are simply forcing Google to pay commissions that it wouldn't otherwise have to pay."

Apparently one way the victim can identify the hijacked results is the lack of the total number of pages that contain the word or phrase for which the victim is searching.
