Attackers may probably exfiltrate delicate recordsdata, manipulate transferred knowledge, implant backdoors, and use the server as a “staging level for ransomware.” The blast radius additional expands in environments the place Serv-U is built-in with Energetic Listing or inside storage methods, Seker identified.
