Gordon Lyon (also known by his pseudonym Fyodor Vaskovich) is an American network security expert, creator of Nmap and writer of books, websites, and technical papers about network security. He is a founding member of the Honeynet Project and was Vice President of Computer Professionals for Social Responsibility. Personal life Lyon has been active in the network security community since the mid-1990s. His handle, "Fyodor", was taken from Russian author Fyodor Dostoyevsky. Most of his programming is done in the C, C++, and Perl programming languages. Opposition to grayware In December 2011, Lyon published his strong dislike of the way Download.com started bundling grayware with their installation managers and concerns over the bundled software, causing many people to spread the post on social networks, and a few dozen media reports. The main problem is the confusion between Download.com-offered content and software offered by original authors; the accusations included deception as well as copyright and trademark violation. Lyon lost control of the Nmap SourceForge page in 2015, with Sourceforge taking over the project's page and offering adware wrapped download bundles. The original SourceForge page no longer contains any files and the Sourceforge "mirror" page used to hijack the Nmap account redirects to the official https://nmap.org/. Websites Lyon maintains several network security web sites: Nmap.Org – Host of the Nmap security scanner and its documentation SecTools.Org – The top 100 network security tools (ranked by thousands of Nmap users) SecLists.Org – Archive of the most common security mailing lists Insecure.Org – His main site, offering security news/updates, exploit world archive, and other misc. security resources Published books Lyon has written and co-authored several books: Know Your Enemy: Revealing the Security Tools, Tactics, and Motives of the Blackhat Community, co-authored with other members of the Honeynet Project. A 2nd edition is now available, as are sample chapters. Stealing the Network: How to Own a Continent. Hacker fiction, but tries to stay realistic. Co-authored with Kevin Mitnick and other hackers. Gordon's chapter is freely available online. Nmap Network Scanning Interviews Public interviews with Lyon/Vaskovich have been posted by SecurityFocus, Slashdot, Zone-H, TuxJournal, Safemode, and Google.
