identYwaf is an identification tool that can recognize web protection type (i.e. WAF) based on blind inference. The blind inference is being done by inspecting responses provoked by a set of predefined offensive (non-destructive) payloads, where those are used only to trigger the web protection system in between (e.g. http://?aeD0oowi=1 AND 2>1). Currently, it supports more than 60 different protection products (e.g. aeSecure, Airlock, CleanTalk, CrawlProtect, Imunify360, MalCare, ModSecurity, Palo Alto, SiteGuard, UrlScan, Wallarm, WatchGuard, Wordfence, etc.), while the knowledge-base is constantly growing.
Also, as part of this project, screenshots of characteristic responses for different web protection systems are being gathered (manually) for the future reference.
