As of yesterday, security company Symantec released a statement claiming there were still 140,000 Macs infected from the recent Flashback malware outbreak that originally infected an estimated 600,000 Mac users. That was despite Apple issuing a Java security update to remove the malware. Today, security researchers from Kaspersky said during a press conference (via Ars Technica) that it estimated infections dropped to 30,000, while still warning more “mass-malware” on OS X is on the way:
“Market share brings attacker motivation… Expect more drive-by downloads, more Mac OS X mass-malware. Expect cross-platform exploit kits with Mac-specific exploits.”
Kaspersky also clarified that much of the Flashback infections were spread through trusted WordPress websites that have been hijacked rather than through malicious downloaded files as many assume. Ars explained:

Over the past few weeks, security experts have warned Mac users of a new virus making its rounds called the “Flashback” trojan. Flashback is allegedly on over 600,000 Macs, which is roughly 1-percent of the 45 million out there. Flashback exploits a pair of vulnerabilities in older versions of Java. Apple may have patched it, but it is still out there and running on many machines.
How do you know if you are infected? F-Secure has a few Terminal commands to check your machine. For the many who are not adept at keeping their Java updates fresh, terminal commands are going to be even more foreign. Luckily, ArsTechnica points us to a free Flashback checker available on github. The app runs the same checks as you would in Terminal, but automates it for you.
We ran the test ourselves and were clean, but one of our readers found that he had the virus last week. It is definitely worth checking out. If your Mac does have Flashback, F-secure offers a great guide on how to remove it.
