NSA leaked documents reveal existence of FOXACID servers that provides an automated hacking platform used to drive operators into hacking targets. FoxACid servers are able also to serve other malicious exploits like United Rake, Peddle Cheap, Packet Wrench, and Beach Head. FoxAcid servers can impersonate a visited website to the target before the legitimate website can respond, thereby tricking the targets browser to visit a Foxacid server. The server can automatically decide what exploit to serve the target, taking into account the risks associated with attacking the target.”]
