DLL Search Order Hijack via Network Share Drop
This rule detects attempts to exploit DLL Search Order Hijacking vulnerabilities by monitoring SMB network traffic for requests containing '.dll' and '\AppData\' in the content. This pattern suggests an attacker might be attempting to drop a malicious DLL into a user's AppData directory on a network share, which could then be loaded by a legitimate application due to search order vulnerabilities, leading to persistence or execution of malicious code.
