SAN FRANCISCO, April 16 (UPI) -- Hard on the heels of the Flashback Trojan that infected 650,000 Apple Mac computers, two new malware programs have been identified, Russian experts say.
Anti-virus firm Kaspersky Lab, which identified the two Trojans, said one is a variant of the Backdoor.OSX.SabPub.a, or simply SabPub, that exploits a Java vulnerability, while the other attacks using Microsoft Word documents, Slash Gear reported Monday.
"SabPub is classic backdoor Trojan, so it opens full access to a victim's system for attackers," Kaspersky Lab chief security expert Alex Gostev said.
"Flashback and its known variants is a downloader and clickjacking bot, which means it conducts click fraud scam by hijacking people's search engine results inside their web browsers," he said.
The new Trojans, both variants of the Flashback malware, could potentially infect more machines than Flashback, especially since the second variant doesn't take advantage of the Java vulnerability, which has now been patched.
Instead, it infects machines through Microsoft Word documents distributed by e-mail, Gostev said.
