If you’re still poking along with Mac OS X 10.5 “Leopard,” Apple has finally gotten around to offering a Flashback Removal Security Update you might want to download.
Flashback is OS X malware which was first discovered late in 2011. It made headlines again in April when a Russian antivirus software developer discovered a new variant of it that exploited an unpatched vulnerability in Java. Apple has since closed the hole and provided a Flashback removal tool for newer versions of Mac OS X, but this will help the few remaining users still working with 10.5 to make themselves more secure.
They’re sure taking their time with this, which is a bad thing. They should release such tools with haste so that the users don’t have any risk of becoming infected.
I tried this, but it does not work on PPCs e.g., my 2.7GHz Dual Tower. So I have turned off JAVA.
As far as I know this Flashback thing doesn’t work on PPC Mac’s anyway. Just really gullible people with Intel Macs.
