A quick note in a quiet moment after @defcon… I meant what I said at the end of @HackerJeopardy. If there are to be solutions found to some of the pressing problems that are facing society right now, I’m betting on hackers. Level up, take it to your home towns…

Come play #HackerPassword and @HackerJeopardy at @CypherCon, because I’m bringing the receipts! #DFIU
Two black NetumScan thermal receipt printers with blue power indicator lights, sitting on a pixelated hacker-themed mat. In front of them, three freshly printed receipts display word cards for a game called β€œHacker Password” β€” Team 1 has the words SMISHING and STACK, Team 2 has TROJAN β€” each with the instruction β€œOne-word clues only.” The setup suggests a live game show in progress, with printed clue cards being dispensed in real time.

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. πŸ”— labs.greynoise.io/grimoire/2… #GreyNoise #ThreatIntel #CyberSecurity #InfoSec

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

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.
A completely original Hacker Jeopardy parody logo that looks nothing like the new Cracker Barrel one.

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!
