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 […]
