This rule detects if a running web pplication appears to be a known or suspected spamming tool. It does this by looking at the output from the application.

False Positives

A false positive can occur when an application legitimately behaves in a manner similar to a spamming tool, or if its output matches known patterns used by spamming tools. The rules contain a large library of known web applications and safe methods that a non-maliciouns, and can detect these known safe web applications and non-malicious methods and ignore them. However it is possible for a new or custom application to trigger this application and incorrectly trigger this rule.

It is not recommended that you disable this rule if you have a false positive. If you believe this is a false positive, please report this to our security team to determine if this is a legitimate case, or if its clever attack on your system.
