Moore is currently the co-founder and chief technical officer of runZero, Inc,[1] a provider of cyber asset attack surface management software and cloud solutions.

[6] He is known for his work in WarVOX, AxMan, the Metasploit Decloaking Engine and the Rogue Network Link Detection Tools,[7] and started a "Month of Browser Bugs" (MoBB) initiative in 2006[8] as an experiment in fast-paced vulnerability discovery with full disclosure.

This model allows WarVOX to find and classify a wide range of interesting lines, including modems, faxes, voice mail boxes, PBXs, loops, dial tones, IVRs, and forwarders using signal processing techniques.

The Metasploit Decloaking Engine is a system for identifying the real IP address of a web user, regardless of proxy settings, using a combination of client-side technologies and custom services.

These tools send spoofed TCP SYN and ICMP Echo Requests with the original destination IP encoded into the packet, which can then be read back out by an external listening host.

Companies such as Microsoft have credited him with discovering vulnerabilities, yet some criticism of Metasploit and similar tools, due to their capacity for criminal use (rather than just offensive security), has fallen upon Moore himself.
