FiletypeID is written in Python, based on PyQt4 and TrIDLib. From our initial use, it seems that it is a GUI for TrID. TrID is a utility designed to identify file types from their binary signatures, that uses a database of definitions which describe recurring patterns for supported file types. Somewhat like PeID, but with lesser features. Since TrID uses an expandable database it will never be out of date. It has about 4697 file type definitions as of now.

Subterfuge is a framework to take the now familiar art of Man-in-the-Middle attack and make it as simple as point and shoot. It has a beautiful, easy to use interface that produces a more transparent and effective attack. This is what sets Subterfuge apart from other attack tools. It demonstrates vulnerabilities in the ARP Protocol by harvesting credentials that go across the network, and even exploiting machines through race conditions. Subterfuge is a small but, effective credential-harvesting program which exploits a vulnerability in the inherently trusting Address Resolution Protocol.
