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

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.
