Summary of cyber attacks that occurred on February 12-18, 2022

The big news in the cyberattacks that occurred on February 12-18, 2022 was that the Conti ransomware group hired the core developers and managers of the TrickBot group, the developers of the TrickBot malware.

With this adoption, the Conti ransomware group is expected to focus on developing further stealthy malware such as BazarBackdoor. Meanwhile, the TrickBot malware will gradually fade away as it is easily detected by antivirus software.

With this merger, Conti has evolved into a real cybercrime syndicate with different groups focused on developing malware for each stage of a ransomware attack (from initial access to encryption).

In other news, the FBI has disclosed a breach of US critical infrastructure by BlackByte, and a new report from Chainalysis sheds more light on the ransomware payments ecosystem.

New ransomware attacks uncovered this week, including BlackByte’s attack on the San Francisco 49ers, Mizuno’s ransomware damage, and BlackCat’s confirmation that it was behind the attack on Swissport.

How to Decrypt Data Infected by Hive Ransomware

Among the many types of malicious code, ransomware is a major threat. Ransomware encrypts data and demands a ransom in exchange for decryption. Without the encryption key, it is impossible to recover the data, so some companies pay huge sums of money or lose important data, which can be very damaging.

Hive Ransomware has caused so much damage that the FBI has issued an alert; to minimize the damage caused by Hive Ransomware and to help victims recover their files, an analysis of Hive Ransomware and recovery methods was conducted.

By analyzing the encryption process of the Hive ransomware, we have confirmed the existence of a vulnerability due to a proprietary encryption algorithm. The attacker’s RSA private key was recovered. Without using the attacker’s RSA private key, we recovered 95% of the master key and actually decrypted the infected data.

This is the first successful attempt to decrypt the Hive ransomware. It is hoped that this method can be used to mitigate the damage caused by the Hive ransomware.

Very interesting stuff on ransomware decryption, but Michael Gillespie says it may not be a practical way to decrypt files encrypted by Hive.
