Washington Post: Because Macs have a reputation for strong security, it's rare for Apple to put out anti-malware software. However, the company says it is working on a new tool that will help Mac users determine if they have been infected with the Flashback malware and to remove the botnet code when found. The company has already released a Java update that fixes the security vulnerability which made Macs susceptible to the malware. Also, the company is working with other companies to shut down the botnet enabled by Flashback. “In addition to the Java vulnerability, the Flashback malware relies on computer servers hosted by the malware authors to perform many of its critical functions,” the company said. “Apple is working with ISPs worldwide to disable this command and control network.”
An estimated 600,000 Macs have become infected with the Flashback malware.
