Zero-Day Exploitation of Unauthenticated Remote Code Execution Vulnerability in GlobalProtect (CVE-2024-3400)
Zero-Day Exploitation of Unauthenticated Remote Code Execution Vulnerability in GlobalProtect (CVE-2024-3400)
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.

How Memory Forensics Revealed Exploitation of Ivanti Connect Secure VPN Zero-Day Vulnerabilities
How Memory Forensics Revealed Exploitation of Ivanti Connect Secure VPN Zero-Day Vulnerabilities
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.

Nokoyawa ransomware attacks with Windows zero-day
Nokoyawa ransomware attacks with Windows zero-day
in February 2023, Kaspersky technologies detected a number of attempts to execute similar elevation-of-privilege exploits on Microsoft Windows servers belonging to small and medium-sized businesses in the Middle East, in North America, and previously in Asia regions. These exploits were very similar to already known Common Log File System (CLFS) driver exploits that we analyzed previously, but we decided to double check and it was worth it – one of the exploits turned out to be a zero-day, supporting different versions and builds of Windows, including Windows 11. The exploit was highly obfuscated with more than 80% of the its code being “junk” elegantly compiled into the binary, but we quickly fully reverse-engineered it and reported our findings to Microsoft. Microsoft assigned CVE-2023-28252 to the Common Log File System elevation-of-privilege vulnerability, and a patch was released on April 11, 2023, as part of April Patch Tuesday.

Move, Patch, Get Out the Way: 2022 Zero-Day Exploitation Continues at an Elevated Pace
  • Mandiant tracked 55 zero-day vulnerabilities that we judge were exploited in 2022. Although this count is lower than the record-breaking 81 zero-days exploited in 2021, it still represents almost triple the number from 2020. * Chinese state-sponsored cyber espionage groups exploited more zero-days than other cyber espionage actors in 2022, which is consistent with previous years. * We identified four zero-day vulnerabilities exploited by financially motivated threat actors. 75% of these instances appear to be linked to ransomware operations. * Products from Microsoft, Google, and Apple made up the majority of zero-day vulnerabilities in 2022, consistent with previous years. The most exploited product types were operating systems (OS) (19), followed by browsers (11), security, IT, and network management products (10), and mobile OS (6).
