Hey @defcon, congratulations to the new @HackerJeopardy champions, Infamous Chalupa. You didn’t fuck it up.

Also, @lintile fucked it up by not thanking the Cal State San Bernardino students for their logistical support tonight. You didn’t fuck it up.

See you next year! #DFIU

We observed a 65% drop in global telnet traffic in a single hour on Jan 14, settling into a sustained 59% reduction. 18 ASNs went silent, 5 countries disappeared, but cloud providers were unaffected.

Our analysis of 51.2M sessions points to backbone-level port 23 filtering by a North American Tier 1 transit provider.

Your #DFIU category today is PUTTING THE F IN PRINTF

This printf conversion specifier lets you write arbitrary values to arbitrary memory addresses, turning logging functions into root shells since 1999

[𝚕𝚒𝚗𝚝𝚒𝚕𝚎 @lintile]

Your #DFIU category today is OG HACKER SHIRTS

This Ron Rivest 1987 cipher, illegal to export from the US (mathematical munitions), fit on 3 lines of Perl and adorned t-shirts as a form of civil disobedience before becoming the WEP protocol's greatest weakness

In trying times like these, it’s important to know that true innovation comes through simplicity. Therefore, team #DFIU has bravely chosen to simplify our logo.

Please direct all complaints to @winnschwartau.
Please direct all congrats to @lintile.

@5n4ck3y @lintile @defcon lol speaking of the Final Jeopardy round of DEF CON 28, this was my view 🤣🤣

[𝚕𝚒𝚗𝚝𝚒𝚕𝚎 @lintile]

We had more good teams than we knew what to do with this year, are going to continue working to ensure that we can feature as much of our community on stage as we possibly can. Until next year, take care of yourself and others, and #DFIU!

Maybe we will see you at a con near you!

[𝚕𝚒𝚗𝚝𝚒𝚕𝚎 @lintile]

Thank you to everyone who has participated with our #DFIU events this year and to everyone that poured their energy into @HackerJeopardy. From our team to all you humans, goons, and everyone in between, thank you for your support.
