A state-sponsored threat actor has managed to compromise Cisco Adaptive Security Appliances used on government networks across the globe and use two zero-day vulnerabilities to install backdoors on them, Cisco Talos researchers have shared on Wednesday."On a compromised ASA, the attackers submit shellcode via the host-scan-reply field, which is then parsed by the Line Dancer implant. The host-scan-reply field, typically used in later parts of the SSL VPN session establishment process, is processed by ASA devices configured for SSL VPN, IPsec IKEv2 VPN with 'client-services' or HTTPS management access," the researchers explained.

Cisco warned today that a state-backed hacking group has been exploiting two zero-day vulnerabilities in Adaptive Security Appliance and Firepower Threat Defense firewalls since November 2023 to breach government networks worldwide. The hackers, identified as UAT4356 by Cisco Talos and STORM-1849 by Microsoft, began infiltrating vulnerable edge devices in early November 2023 in a cyber-espionage campaign tracked as ArcaneDoor.

An operator of the HelloKitty ransomware operation announced they changed the name to 'HelloGookie,' releasing passwords for previously leaked CD Projekt source code, Cisco network information, and decryption keys from old attacks. To celebrate the launch, the threat actor released four private decryption keys that can be used to decrypt files in older attacks, as well as internal information stolen from Cisco in a 2022 attack and passwords for the leaked source code for Gwent, Witcher 3, and Red Engine stolen from CD Projekt in 2021.

Cisco has released patches for a high-severity Integrated Management Controller vulnerability with public exploit code that can let local attackers escalate privileges to root. "A vulnerability in the CLI of the Cisco Integrated Management Controller could allow an authenticated, local attacker to perform command injection attacks on the underlying operating system and elevate privileges to root," the company explains.

Cisco warns about a large-scale credential brute-forcing campaign targeting VPN and SSH services on Cisco, CheckPoint, Fortinet, SonicWall, and Ubiquiti devices worldwide. The researchers say the attacks started on March 18, 2024, while all attacks originate from TOR exit nodes and various other anonymization tools and proxies, which the threat actors use to evade blocks.
