To mitigate the risks associated with legacy S7 password vulnerabilities, organizations should adopt a defense-in-depth strategy:
In legacy S7 communications, the password protection mechanism was found to be vulnerable to "Pass-the-Hash" style attacks. Research demonstrated that the password itself was often not required to be cracked offline. Instead, if an attacker could intercept a legitimate authentication session (via Man-in-the-Middle attacks or network sniffing), the authentication token could be captured and replayed to gain unauthorized access.
