Microsoft Warns of ZCryptor Ransomware With Self-Propagation Features (softpedia.com)
An anonymous reader writes from a report issued by Softpedia on May 27: Microsoft and several other security researchers have detected the first ransomware versions that appears to have self-propagation features, being able to spread to other machines on its own by copying itself to shared network drives or portable storage devices automatically. Called ZCryptor, this ransomware seems to enjoy quite the attention from crooks, who are actively distributing today via Flash malvertising and boobytrapped Office files that infect the victim if he enables macro support when opening the file. This just seems to be the latest addition to the ransomware family, one which recently received the ability to launch DDoS attacks while locking the user's computer.
They're the king of ransomware, forcing Windows 10 installations.
and data. After twenty years of problems with code in documents, including some that would wipe-out your partition table, they still allow code in a document to execute.
Also, this might be the first malware that infected network files, but it certainly isn't the first to affect Office documents. We've been hit several dozen times.
More proof that everyone should be using an adblocker to keep their computer and friends computers safe.
Dear website owners.... WAHH about your lost revenue. start hosting the ad's on your own servers and VET THEM to be safe and not an attack vector.
Do not look at laser with remaining good eye.
This stuff is nasty.
1- Have spotless offline backups of everything
2- Lock down share permissions
3- Lock down admins on permissions domain level
4- Lock down admins on local machine level
5- Pray
I had to deal with this garbage once earlier this year on a custom domain with awful permissions management. It was bad enough from a single source\spread to shares perspective. I can't imagine the damn thing acting like a worm at the same time. Potentially career ending because 1- your enterprise gets owned so hard and 2- you never want to touch a computer again once you have to try to clean it up.
Or use OpenOffice or LibreOffice instead. Heck, even Google Docs is better now.
not to use flash. I understand that there are many companies with a significant investment in flash-based code. But flash has proven to be a persistent security hole. HTML 5 is a viable alternative to flash. time for those companies to suck it up.
