Alert Message	Atomicorp.com WAF Rules: Fake Baidu webcrawler

Description

This exclusive capability in the Atomicorp ruleset can detect when a client pretends to be the Baidu webcrawler. This helps to detect and block potential zero day and other suspicious behavior. Attacks have been know to impersonate webcrawlers to trick naive applications that blinding trust webcrawlers. They use this method to gain access that would otherwise be blocked to non-crawlers.

This will not block the real Baidu webcrawler. We do not recommend you disable this rule.

For ASL users, if you enable the option below, ASL will automatically and dynamically whitelist the real Baidu webcrawler from all WAF events:
