The System Service Descriptor Table (SSDT) is an internal dispatch table within Microsoft Windows.

Hooking SSDT calls is often used as a technique in both Windows rootkits and antivirus software.[1][2]

In 2010, many computer security products which relied on hooking SSDT calls were shown to be vulnerable to exploits using race conditions to attack the products' security checks.[2]
