If employees receive a ransomware demand, they should know to immediately report it to the security team-and never, ever try to pay on their own.

Your people should know what to do, what not to do, how to avoid ransomware, and how to report it.

Keep operating systems, security software and patches up to date for all devices.Įmployee training and awareness are critical. Both halves are important restore drills are the only way to know ahead of time whether your backup plan is working. Surprisingly few organizations run backup and restore drills. The most important part of any ransomware security strategy is regular data backups. This requires planning and work-before the crisis hits. The best security strategy is to avoid ransomware altogether. So there’s no way for victims to send the money or get the decryption key. The attackers’ contact email was hard-coded to a webmail address that was quickly shut down. The NotPetya ransom, however, is nearly impossible to pay. Finally, the system reboots again, displaying the ransom demand.

As users wait, Petya is actually encrypting their files.

It then displays the text “Repairing file system on C:” and warning users not to turn off their computers. Once it has infected a system, Petya waits about an hour before rebooting the machine. This limited the spread and is consistent with the theory that NotPetya was a narrowly targeted attack rather than a cyber criminal’s cash grab. At the same time, it wasn’t designed to spread beyond the initially infected environment. That made NotPetya much more resilient to cyber defenses. Though it exploited the same flaw as an earlier ransomware strain called WannaCry, it had more options for spreading itself. A second wave of attacks spread through malware-laden phishing emails.

Those traits led researchers to conclude that the virus was a state-sponsored destructive attack, not an act of cybercrime.Īccording to the Ukrainian police, the NotPetya attack started by subverting the update function of that government’s accounting software.

And despite displaying the usual signs of a ransomware attack-such as the ransomware demand-wasn’t designed to actually collect any money. NotPetya was narrowly targeted, though quickly grew into a wider threat. That behavior made NotPetya more like a “ransomworm” than a traditional virus. Unlike most malware, NotPetya infected new systems without the user doing anything. Once on a compromised system, EternalBlue exploits a flaw in Windows networking protocols to silently spread across networks. The exploit was developed by-and later stolen from-the U.S. The new variant, also dubbed “NotPetya” because of key differences with the original, spread using an exploit known as EternalBlue. It quickly spread worldwide, crippling businesses and causing more than $10 billion in damages. Though first discovered in 2016, Petya began making news in 2017 when a new variant was used in a massive cyberattack against Ukrainian targets.
