Massive Ransomware Outbreak
We have an update on this outbreak here. The ransomware is using an NSA exploit leaked by The Shadow Brokers, and has made tens of thousands of victims worldwide, including the Russian Interior Ministry, Chinese universities, Hungarian telcos, FedEx branches, and more. Original article below.
A ransomware outbreak is wreaking havoc all over the world, but especially in Spain, where Telefonica — one of the country’s biggest telecommunications companies — has fallen victim, and its IT staff is desperately telling employees to shut down computers and VPN connections in order to limit the ransomware’s reach.
The culprit for these attacks is v2.0 of the WCry ransomware, also known as WannaCry or WanaCrypt0r ransomware. For those affected, you can discuss this ransomware and receive support in the dedicated WanaCrypt0r & Wana Decrypt0r Help & Support Topic.
WCry ransomware explodes in massive distribution wave
Version 2.0 was detected for the first time around four hours ago by independent security researcher MalwareHunter. The security researcher says the ransomware came out of nowhere and started spreading like wildfire.
In these first four hours, WCry 2.0 made more victims than Jaff, a ransomware spotted this week distributed via the Necurs botnet, the former home of the Locky ransomware. In numbers, in just four hours WCry made 1.5 times more victims than Jaff did all week.
Currently, researchers weren’t able to pinpoint the exact origin of the WCry distribution campaign. At the moment, it could be from malvertising, exploit kits, email spam, or hand-cranked RDP attacks.
