Lynn B. Friedman - Atlanta Homes ODAT Realty: Ransomware Attack on MAC - Apple Users Face Danger - BEWARE!

Ransomware Attack on MAC - Apple Users Face Danger - BEWARE!

Ransomware Attack on MAC -
Apple Users Face Danger - BEWARE!

UPDATE: Check the 3/11/16 announcement from "Dr. Web"

The Ransomware Attack on Mac reported by the following news services is pernicious. Named KeRanger, it sits dormant for three days and then spreads its infection. The thieves gained entry to a free BitTorrent client available for Mac. Starting with an application signed with a valid Mac development certificate, KeRanger was able to avoid the Gatekeeper protection provided by Apple. That led to unsuspecting users becoming the targets of a Mac Ransomware Attack.

What happens? Via KeRanger, the thieves encrypt all of the data on a computer and offer to release it when the owner pays a bit-coin ransom.

The bad news? Users of the infected BitTorrent may still be at risk until they download Transmission/Version 2.92.

The good news? KeRanger was detected. Palo Alto Networks security firm disabled KeRanger. The offending installer has been replaced with one that automatically removes the ransomware from infected Macs. Protect yourself by installing Transmission Version 2.92.

The researchers at Palo Alto Networks stated that: "The only previous ransomware for OS X we are aware of ... [was] discovered by Kaspersky Lab in 2014. As [the ransomware named FileCoder] was incomplete at the time of its discovery, we believe KeRanger is the first fully functional ransomware seen on the OS X platform."

The bad news? Users of the infected BitTorrent may still be at risk until they download Transmission/Version 2.92.

Due to the Mac Ransomware Attack, according to the reports, Apple took immediate action. Revoking the Certificate was the first step. Then countering the attack began. This iteration of Ransomware Attack on Mac is a first. Owners of PCs have suffered from this situation for a while now.

PRECAUTION? Whether you are on a Mac or PC - maintain a complete cloud-based copy of everything you need. In addition, perhaps use a removable storage to copy your data as well. Then you may ignore the Ransomware Attack on Mac or any other system. Get infected? Consult your computer technician and start all over with the data you need!

To explain more about the situation clearly would require extensive quotations from other posts and it will be easier for readers to go directly to those posts. That allows each reader to delve as deeply into the reporting as needed to understand the Mac Ransomware Attack.

The Posts to read - in decreasing technical order - are:
Palo Alto Research. The post, written by the people who resolved the threat, is very technical and includes illustrations of code used for the infection to enable others to seek out the issues on their own systems.

Reuters reported on the Palo Alto post. They quoted that the threat, detected and countered by March 6, 2016,  would begin to appear on Monday, March 7th on infected computers.

Make Use Of offers an abreviated explanation of the situation drawing on the Reuters post.

I agree to keep a copy of everything on I cloud. We need to protect our business and personal stuff. Thanks for the heads up on this Ransomware Attack. J

Hello Lynn ... very interesting for Mac users and the sad thing is, I believe the founders of PC, Mac's and all computers in general have hackers create viruses, etc. so they can bank people that use computers.

This is a terrible though and thanks for your information
