Ransomware Target: Apple Mac Users

Apple Mac Users
Apple customers all had a big bulls-eye on their back a few days ago during the first campaign against Macintosh computers using a pernicious type of software known as ransomware, researchers with Palo Alto Networks told Reuters last 6 March.

Ransomware, one of the fastest-growing types of cyber threats, encrypts data on infected machines, then typically asks users to pay ransoms in hard-to-trace digital currencies to get an electronic key so they can retrieve their data.

Security experts estimate that ransoms total hundreds of millions of dollars a year from such cyber criminals, who typically target users of Microsoft Corp's Windows operating system.

Palo Alto Threat Intelligence Director Ryan Olson said the "KeRanger" malware, which appeared on 4 March, was the first functioning ransomware attacking Apple's Mac computers.

"This is the first one in the wild that is definitely functional, encrypts your files and seeks a ransom," Olson said in a telephone interview.

An Apple representative said the company had taken steps over the weekend to prevent attacks by revoking a digital certificate from a legitimate Apple developer that enabled the rogue software to install on Macs. The representative said he could not immediately provide other details.

The malware is programmed to encrypt files on an infected personal computer three days after the original infection, according to Olson.

That means that if Apple's steps prove ineffective in neutralizing malware that has already infected Macs, the earliest victims had their files encrypted last 7 March, three days after the malicious program first appeared on the Tranmission website, he said.

The Transmission site offers the open source software that was infected with the ransomware.

Palo Alto said it planned to release a blog advising Mac users on ways to check to see if they were infected with the virus and steps they can take to protect against it harming their data, Olson said.
