Enter – When MEDoc customers installed the software update, the Petya code ran on an enterprise host and began to propagate in the enterprise.

As organizations updated the application, the Petya code was initiated.

Prepare – The Petya attack began with a compromise of the MEDoc application.

Here are the four steps in the Petya kill chain: The Petya attack chain is well understood, although a few small mysteries remain. Next, we will go into some more details on the Petya (aka NotPetya) attack. In the first blog post of this 3-part series, we introduced what rapid cyberattacks are and illustrated how they are different in terms of execution and outcome.

Petya was one of the first types of ransomware to gain major success by spreading itself via a 'ransomware-as-a-as- service' scheme, whereby the author allowed budding hackers and cybercriminals to use the malicious code for their own ends - in exchange for a cut of the profits. Unfortunately, along with being able to do nothing for NotPetya victims, the Petya decryptor can't do anything for those hit by illegitimate versions of the ransomware such as PetrWrap. The different versions display the Bitcoin demanding ransom note written in the colours the versions are named after.įollowing the NotPetya outbreak, the author of the original version of the ransomware, Janus, released his master key and now cybersecurity researchers at Malwarebytes Labs have used the key to release a decryptor that can decrypt all legitimate versions of Red Petya, Green Petya, and GoldenEye and recover the lost files.īut the researchers warn that during tests it found that in some cases Petya may hang during decryption, or cause some other problems potentially damaging to data and said: 'That's why, before any decryption attempts, we recommend you to make an additional backup.' Not only does Petya encrypt the victims' files using one of the most advanced cryptographic algorithms around, it also encrypts the entire hard drive by overwriting the master reboot record, in order to prevent the computer from loading the operating system.īut one version of the ransomware wasn't enough for its creators, who not only developed the original 'Red Petya', but also 'Green Petya' variants along with a golden-themed version named GoldenEye after the weapon in the 1995 James Bond film.
