Are 600 000 Infected Macs Including Hundreds In Cupertino Part Of A Global Botnet

ArsTechnica quotes a Russian antivirus company called “Dr. Web” that claims hundreds of thousands of Macs are infected with the Flashback Trojan detailed earlier this week. The attack takes advantage of an old Java vulnerability that Apple just patched this week.

Dr. Web said over half of the infected computers were in the United States (including 274 in Cupertino), and 20 percent were in Canada. The malware self-installs after you visit a compromised or malicious webpage. Obviously, it would be a good idea to update any Macs in your control.
