- Bitdefender Introduces a Decryptor Tool for the LockerGoga Ransomware
- More Information on Ragnor Locker Ransomware
Bitdefender—in collaboration with law enforcement agencies, including Europol, the No More Ransom Project, the Zürich Public Prosecutor’s Office, and the Cantonal Police of Zürich—has developed a free decryptor tool to recover files encrypted by the LockerGoga ransomware. The free tool and a user guide are available for download from Bitdefender’s servers.
LockerGoga is a ransomware group that has been operational since January 2019 and has attacked prominent organizations all over the world. It is estimated that the group has caused damages worth $US 104 million with its activities. Twelve members of the group were arrested in October 2021, causing the group’s operations to cease.
The free tool is expected to be used by victims, whose files are still encrypted, of the LockerGoga group.
CVE-2019-3396 is the CVE targeted by the LockerGoga group.
Ragnor Locker has been making headlines in the news with its attacks on Air Portugal, DESFA, etc.
There is now more information about how this ransomware group operates. The attacks are carried out on Windows and Linux systems where a compromised machine is used to gather information and also encrypt files using the Salsa 20 encryption algorithm. Once this is done, the group employs the double extortion tactic to get ransom from their victims—to decrypt the files and not publish the stolen information to the public.
The Ragnor Locker ransomware also deletes volume shadow copies and terminates services, such as VSS, SQL, Veeam, LogMeIN, etc., to keep the victim from recovering the affected files.
CVE-2017-0213 (Windows COM Elevation of Privilege Vulnerability) is a vulnerability that Ragnor Locker exploits. It uses the RDP services exposed to the internet to compromise victim machines with brute-forcing techniques and leaked credentials
The FBI warned organizations against Ragnor Locker in March 2022.
