If anybody still thought Apple devices were bulletproof, the Flashback drive-by episode last month should have provided the needed reality check.
Symantec said on Tuesday the Flashback malware that attacked Apple Mac computers could have netted its authors up to $10,000 a day.
Of the Macs that have been infected by the Flashback malware, nearly two-thirds are running OS X 10.6, better known as Snow Leopard, Russian antivirus firm Dr. Web says.
Oracle is now giving Mac users the ability to get Java updates at the same time as they are available for Windows and Linux with the release of the Java SE 7 Update 4.
The Mac Flashback Trojan horse was still installed on more than half a million Apple computers late last week and is declining only slowly, Russian security company Dr. Web claims.
Contrary to reports by several security companies, the Flashback botnet is not shrinking, according to the Russian antivirus firm that first reported the massive infection.
A large spam campaign observed on Twitter during the last couple of days directed users to malicious websites that exploited vulnerabilities in browser plug-ins to infect their computers with rogue antivirus programs.
Mozilla this week began blocking outdated versions of a Java plug-in in Firefox for some Mac users after calling the threat posed by the Flashback malware "evident and imminent."
Fear your Mac has the Flashback malware installed, but you aren't running Java? You'll want to grab Apple's standalone removal tool.
