With that free key, affected companies can regain full control of files held hostage by REvil’s ransomware. The key was developed by cybersecurity firm Bitdefender in collaboration with “a trusted law enforcement officer”.
Although the investigation into the major ransomware attack is still ongoing, it has been decided to already release the universal decryption key, so that as many victims as possible can move forward. Furthermore, Bitdefender can give few details about the investigation.
Hackers demanded $70 million
At the beginning of July, thousands of companies were affected by the ransomware from hacker group REvil. Files and payment systems belonging to those companies were not accessible, and REvil demanded a ransom of $70 million in bitcoin to release the decryption key.
On July 13, REvil’s servers went offline. Therefore, victims who had not paid ransom could not access their files. Bitdefender’s universal key should now provide a solution for all REvil victims before July 13.
‘REvil is back, caution is advised’
Meanwhile, REvil’s servers have come back online. “We believe that new attacks are imminent. We urge organizations to be alert and take the necessary precautions,” Bitdefender said.
At the end of July, the company Kaseya also came up with a decryption key. The major REvil ransomware attack was carried out through Kaseya’s IT management software. That key was only available on request, Bitdefender’s key is free for anyone to download.
