Nasty Trojan attacked 650,000 Mac Computers, another Apple threat is on the prowl

Nasty Trojan horse virus hit 650,000 Mac computer all over the world and still counting. It has been noted that the virus has been spread at the rapid pace recently and are viral. Kaspersky Lab and other security firms reported that their are more than one popular Mac virus which is active atm.

According to anti-virus software provider Kaspersky Lab, a Trojan called SabPub — or more formally, Backdoor.OSX.SabPub.a — has recently been spreading via Java and could be infecting computers when people open email messages with suspicious links that direct users to malware.

Alex Gostev, chief security expert of Kaspersky Lab said that:

“The Flashback and the SabPub Trojans are totally different, -- SabPub is classic backdoor Trojan, so it opens full access to a victim’s system for attackers. Flashback and its known variants is downloader and clickjacking bot, which means it conducts click fraud scam by hijacking people’s search engine results inside their web browsers.”

Last week, Apple released a security patch for Java that prevents the Flashback Trojan — called “Flashfake” — from exploiting the vulnerability to infect computers. Since then, Kaspersky Lab said it has seen a decline in the number of active bots for Flashfake, dropping from more than 650,000 infected computers to just 237,000.

However, the decrease in infected bots does not mean the botnet is on its way out. The numbers represent the active bots connected to Flashfake during the past few days – it is not the equivalent of the exact number of infected machines. Infected computers that were inactive during Easter weekend would not be communicating with Flashfake, which makes them not appear as an infected bot, Kaspersky said.
