Hey there, have you heard about the latest attack strategy that’s been making waves in cybersecurity circles? It’s called NachoVPN, and it’s causing quite a stir by targeting corporate clients like Palo Alto and SonicWall SSL-VPN clients. This attack takes advantage of unpatched vulnerabilities to sneak malicious updates onto target systems.
Unveiling the NachoVPN Attack
Researchers at Amberwolf have uncovered a new attack method that specifically goes after corporate VPN clients. Known as the NachoVPN attack, it tricks unsuspecting VPN clients into connecting to fake endpoints controlled by the attackers. Once connected, these cybercriminals can carry out various malicious activities, including stealing login credentials.
This attack isn’t limited to just a few VPN clients. In fact, the researchers identified a wide range of vulnerable clients, dubbing them “Very Pwnable Networks.” They demonstrated the NachoVPN attack on two popular VPN clients, SonicWall NetExtender, and Palo Alto Networks GlobalProtect VPN. Essentially, the attackers lure users into connecting to their rogue endpoint through phishing or social engineering, granting them the ability to execute harmful codes and carry out nefarious deeds.
If you’re curious to learn more about the “Very Pwnable Networks” and how NachoVPN works, check out the video from HackFest Hollywood 2024 shared below. The researchers have also provided technical insights into the vulnerabilities exploited in SonicWall and Palo Alto clients.
If you’re feeling adventurous, you can even test out the NachoVPN tool released by the researchers on GitHub. This tool isn’t limited to just SonicWall and Palo Alto clients; it works with other VPN clients like Cisco AnyConnect as well.
Good news! The vendors have already patched the vulnerabilities that NachoVPN exploited. SonicWall fixed the SSL VPN NetExtender vulnerability with NetExtender Windows 10.2.341, while Palo Alto Networks addressed the GlobalProtect app flaw with version 6.2.6 and higher.
It’s crucial to update your devices promptly to stay protected from potential threats. Remember, your security is in your hands!
