Attackers Exploit Maximum Severity Flaw in Attacks on Network Security

Network security systems were impacted

Attacks exploiting known security flaws impacting internet-facing systems have been deployed by the new TAG-100 threat operation, as part of a cyberespionage campaign against private and government organizations in the US and other parts of the world.

According to The Hacker News, systems including Microsoft Exchange Server, SonicWall and F5 BIG-IP, as well as the open-source Pantegana and Spark RAT backdoors, were impacted.


TAG-100 also leveraged the remote code execution flaw CVE-2024-3400, which impacted Palo Alto Networks’ GlobalProtect firewalls, analysis from Recorded Future's Insikt Group revealed.

"The widespread targeting of internet-facing appliances is particularly attractive because it offers a foothold within the targeted network via products that often have limited visibility, logging capabilities, and support for traditional security solutions, reducing the risk of detection post-exploitation," said Recorded Future researchers.
