Volexity would like to thank Palo Alto Networks for their partnership, cooperation, and rapid response to this critical issue. Their research can be found here. On April 10, 2024, Volexity identified zero-day exploitation of a vulnerability found within the GlobalProtect feature of Palo Alto Networks PAN-OS at one of its network security monitoring (NSM) customers. Volexity received alerts regarding suspect network traffic emanating from the customer’s firewall. A subsequent investigation determined the device had been compromised. The following day, April 11, 2024, Volexity observed further, identical exploitation at another one of its NSM customers by the same threat actor. The threat actor, which Volexity tracks under the alias UTA0218, was able to remotely exploit the firewall device, create a reverse shell, and download further tools onto the device. The attacker focused on exporting configuration data from the devices, and then leveraging it as an entry point to move laterally within […]

KEY TAKEAWAYS Russian APT GruesomeLarch deployed a new attack technique leveraging Wi-Fi networks in close proximity to the intended target. The threat actor primarily leveraged living-off-the-land techniques. A zero-day privilege escalation was used to further gain access. Ukrainian-related work and projects were targeted in this attack, just ahead of Russian Invasion of Ukraine. In early February 2022, notably just ahead of the Russian invasion of Ukraine, Volexity made a discovery that led to one of the most fascinating and complex incident investigations Volexity had ever worked. The investigation began when an alert from a custom detection signature Volexity had deployed at a customer site (“Organization A”) indicated a threat actor had compromised a server on the customer’s network. While Volexity quickly investigated the threat activity, more questions were raised than answers due to a very motivated and skilled advanced persistent threat (APT) actor, who was using a novel attack vector Volexity […]
