Blank Slate, Blank Cheque

Brad Duncan for Palo Alto: “Blank Slate” Campaign Takes Advantage of Hosting Providers to Spread Ransomware.

Palo Alto call it ‘Blank Slate’ because the malicious attachment is distributed via a blank email (spoofed sender and no message content).

Apparently primarily distributes Cerber, but also Sage 2.0 and Locky.

KeRanger OS X ransomware campaign

[Updated 7th March 2016:

According to a ComputerWorld story, (and confirmed elsewhere) Apple has revoked the certificate of the compromised version of BitTorrent client Transmission and updated Xprotect.]

Palo Alto reported on March 6th that New OS X Ransomware KeRanger Infected Transmission BitTorrent Client Installer: they believe this to be ‘the first fully functional ransomware seen on the OS X platform.’ At any rate, it looks like a capable piece of malware. According to fortune.com,  Palo Alto plans ‘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’.

Info also added to the Mac Virus blog and the AVIEN ransomware resource page. More info as the story develops, if time allows.
