The Nmap Project mourns the passing of our friend and legendary hacker Kevin Mitnick. He helped inspire my (Fyodor's) passion for network security, as well as Nmap features such as the TCP Initial Sequence Number predictability report. Later we worked together on the hacking novel "Stealing the Network: How to Own a Continent". Here's a fun pic from our 2004 HOPE Conference book signing. Rest in peace, @kevinmitnick.

This is my love-letter to @nmap, which most certainly changed the course of my life, and probably yours, too. 1997 was a pretty magical year for infosec, nmap being chief among the reasons.

Rest in peace, Dan Kaminsky (@dakami). You were always a great friend to the Nmap Project. And to practically everyone else in Infosec too.

Google Chrome has been blocking Nmap downloads all day because their broken "Safe Browsing" system suddenly labeled a 10-year-old version of our Ncat software as a threat. We will get this resolved with Google, but wanted to let you know that your Nmap downloads are still safe!

Last week Google Chrome wrongfully blocked a 24-year-old tarball of L0phtcrack source code from our historical archives as "malware". That one has been fixed, but it's still frustrating when Big Tech companies block content so carelessly.
