Stealthy Cyberespionage Campaign Remained Undiscovered for Two Years: A non-profit organization in Saudi Arabia was targeted in a stealthy cyberespionage campaign that went undetected for two years. The campaign utilized a custom backdoor called Zardoor, modified reverse proxies, and the abuse of legitimate tools for malware delivery and command-and-control setup. The threat actor has remained unidentified, but their advanced techniques and ability to maintain long-term access to the victim's network suggest there may be other compromised targets. #Cyberespionage #DataBreach #ThreatActor
