In a joint warning released earlier this week, CISA, the NSA, and MS-ISAC expressed concerns that threat actors are increasingly utilising remote monitoring and management (RMM) software for malicious purposes.

More concerningly, following the publication of a Silent Push report in mid-October 2022, CISA used the EINSTEIN intrusion detection system to find hostile activity inside the networks of many federal civilian executive branch (FCEB) agencies.

After being discovered on one FCEB network in mid-September 2022, this activity was connected to the “widespread, financially driven phishing campaign” mentioned by Silent Push and was found on many other FCEB networks.

Biggest car dealer network in the UK affected by ransomware

Glasgow-based Following a cyberattack on its systems, Arnold Clark, one of the biggest auto dealer networks in the UK that made its founder a fortune, is dealing with a multimillion-pound ransom demand from the Play double extortion ransomware ring.

Staff had to use pen and paper to record consumer transactions after the assault on the organisation, which occurred in the run-up to Christmas. Additionally, it was unable to finish handing out new automobiles.

Following the incident, Arnold Clark voluntarily removed its computers after receiving a warning about suspicious network activity from an external security expert. It then worked with its online partners to perform a thorough evaluation of its IT infrastructure. It said that protecting client data, its own systems, and its third-party partners had been a top priority and that this had been accomplished.


Hive ransomware seized by joint law enforcement operation

As part of a concerted law enforcement investigation spanning 13 nations, the Hive ransomware-as-a-service (RaaS)  infrastructure has been seized. 

“Law enforcement identified the decryption keys and shared them with many of the victims, helping them regain access to their data without paying the cybercriminals,” Europol said in a statement.

The FBI penetrated the Hive networks in July 2022 and captured over 300 decryption keys that were then handed over to companies compromised by the gang, effectively saving $130 million in ransom payments. The FBI also distributed more than 1,000 additional decryption keys to previous Hive victims.

Since 2021, Hive has been a prolific cybercrime crew, launching attacks against 1,500 organizations in no less than 80 countries and netting $100 million in illicit profits.
