A few days ago, at the foreign platform Reddit information appeared on the detection of a security vulnerability in the Atlasvpn client for Linux operating systems.
An anonymous cybersecurity researcher has published a proof-of-concept (POC) exploit.
Exploits are typically classified based on the type of vulnerability they exploit, whether they are local or remote, and their resulting effect (such as Elevation of Privilege, Denial of Service, or Information Disclosure). One of the common schemes for offering zero-day exploits is through Exploit-as-a-Service.
