In the ever-evolving world of cybersecurity, researchers from Sophos have unearthed a troubling hacking campaign that has sent ripples through the digital realm. Enter ‘STAC4663,’ a group of threat actors with a mission – exploiting a well-known vulnerability to conduct widescale domain attacks.
The vulnerability in question, CVE-2023-3519, served as their gateway to infiltrate susceptible systems and unleash a barrage of malicious software. This exploit stems from a remote code execution flaw that first came to light earlier in the summer, affecting Citrix NetScaler systems.
