Volexity regularly prioritizes memory forensics when responding to incidents. This strategy improves investigative capabilities in many ways across Windows, Linux, and macOS. This blog post highlights some specific ways memory forensics played a key role in determining how two zero-day vulnerabilities were being chained together to achieve unauthenticated remote code execution in Ivanti Connect Secure VPN devices.| Volexity
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 le...| Volexity

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 custome...| Volexity
Volexity has uncovered active in-the-wild exploitation of two vulnerabilities allowing unauthenticated remote code execution in Ivanti Connect Secure VPN appliances. An official security advisory and knowledge base article have been released by Ivanti that includes mitigation that should be applied immediately. However, a mitigation does not remedy a past or ongoing compromise. Systems should simultaneously be thoroughly analyzed per details in this post to look for signs of a breach.| Volexity
