Security firm warns of new Flashback variant.
According to a post from security company Intego, the malware that infected over half a million Macs a few weeks back is making a return.
Dubbed ‘Flashback.S’, the new variant “continues to use a Java vulnerability that Apple has patched”, and installs without requesting for a password. It then deletes the original applet to avoid being discovered by antivirus and removal tools. Ironically enough, Intego mentions that the malware isn’t able to install on Macs running their security software.
The original malware masqueraded as a browser plugin which if installed would collect personal information and send it back to remote servers. Apple were quick to respond and deployed a security fix to address the Java vulnerabilities.
