An Ad-Fraud Trojan that updates Flash for you? Nice!
Someone call the malware antitrust commission: Recent versions of the Kovter ad fraud Trojan, which infects computers through Web-based exploits, close the door after themselves by updating Flash Player to the latest version.
The new and somewhat surprising behavior was recently observed by a malware researcher known online as Kafeine, who specializes in tracking drive-by download attacks that use exploit kits.
Kovter is used for so-called click or advertising fraud. Once installed on a computer, it hijacks the browser process and uses it to simulate user clicks on online advertisements in order to generate revenue for its creators.
