“Thanks to the currently published master key, all the people who have preserved the images of the disks encrypted by the relevant versions of Petya, may get a chance of getting their data back,” Hasherezade wrote. Petya’s author subsequently updated the ransomware preventing those earlier decryption tools from working. A Twitter user by the name came up with the genetic algorithm to generate passwords and a security researcher at Emsisoft, created an executable designed to extract data from infected Petya drives. The Petya ransomware lock screen warned that your hard drive was encrypted with military grade encryption and the only way to unlock it was to cough up the bitcoins to purchase a password.
In April 2016, researchers developed a unique decryption tool that allowed most victims to generate a key to decrypt early Petya ransomware versions. The ransomware has demanded around $400 in Bitcoin for the decryption key. Petya is crypto-malware that is known for targeting a victim’s Master Boot Record instead of files stored on the computer, network shares or backups that the computer may have access to. It goes by various names such as Not Petya, ExPetr, Eternal Petya, and sometimes GoldenEye, Hasherezade said. Unlike previous versions, this version lacked the ability to decrypt effected systems and was considered wiper malware. Is It Possible To Unlock Ransomware Due to the fact that the decryption key is usually stored on the server of the cybercriminal, it is usually not possible to. That latest version of the malware, based on pirated GoldenEye code, was believed used in last month’s wiper outbreak that originated in the Ukraine. Paying Off 'Petya-Variant' Ransomware Won't Unlock Your Files A new ransomware researchers say is based on 'Petya' malware is spreading globally - but paying it off won't unlock your files.
This year, the “compiled application” was stolen and modified by another threat actor. It was the fourth version based on the Petya code. Unlike some older ransomware strains, which only encrypt certain important. The operators of Petya demand payment in Bitcoin before they will decrypt the files and make them usable again. Like other types of ransomware, Petya encrypts files and data on the victim's computer. “The published #Petya master key works for all versions including #GoldenEye,” tweeted Ivanov.Īccording to Hasherezade, GoldenEye ransomware was first created by Petya author Janus in 2016. Petya is a strain of ransomware that was first identified in 2016. “Similarly to the authors of TeslaCrypt, (Janus) released his private key, allowing all the victims of the previous Petya attacks, to get their files back,” wrote Hasherezade, a researcher for MalwareBytes that posted her finding on Thursday.įurther analysis of the master key by Kaspersky Lab research analyst Anton Ivanov confirmed the key unlocks Petya ransomware and early versions the GoldenEye ransomware. The master key to the original version of the Petya ransomware – not to be confused with the latest and massive Petya/ExPetr outbreak that swept through the Ukraine and parts of Europe last month – has been released, allowing all the victims of previous Petya attacks to unscramble their encrypted files.Īccording to researchers, the author of the original Petya ransomware, which goes by the pseudonym Janus, made the key available on Wednesday.
