Updated Guide to Using the MITER ATT & CK Knowledge Base Published
The US Cyber and Infrastructure Security Agency (CISA) has published a new guide to using the MITER ATT & CK knowledge base for cyber intelligence experts. The reason for the update was that, according to the agency, information security specialists do not fully use the potential of the knowledge base. The new guidance is designed to help cyber threat analysts align attackers’ tactics, techniques and procedures with those of ATT & CK.
New method of cyber attacks on enterprises discovered
Kaspersky Lab specialists have discovered a new approach to attacks against large organizations. The essence of the approach is that when carrying out attacks, cybercriminals associate exploits for 0-day in Google Chrome and Windows 10. This method was first used by the PuzzleMaker grouping. With this method, cybercriminals ultimately manage to successfully execute code on their victims’ devices.
JBS paid ransom to REvil
The company paid $ 11 million to prevent the publication of previously stolen data. Initially, the attackers asked for a ransom in the amount of $ 22.5 million, but after negotiations, the price was reduced to $ 11 million. As of today, a decryptor for data recovery has been handed over to JBS.
