@CriticalStack I'm getting a 502 bad gateway error on intel.criticalstack.com. Is this an issue or is the service no longer?
@Hectaman @CriticalStack That's awkward of me! Thanks for following up. I'll take a much harder look at my setup.
@CriticalStack Really seems like something's been up since 8/23. That's the last time we've seen a substantial intel import.
@CriticalStack Wondering if the intel marketplace is still active? Haven't seen any new intel since 9/27 and no response to support request.
Sad to see CapitalOne 360 rolling back all the intelligent security controls that RSA and ING Direct had on their banking app.
I'm looking for an extra Shmoocon ticket at cost to help send a talented infosec college student to her first conference. Can anyone help?

@gheimer Funny, I though of him the other day. Guy at work who looks like 'em. Still white hat ;) Marathon on Sunday...woot!
From website/pamphlet-- "You don't need a badge to see the 101 Talks..." -- Lies! #DEFCON
Anyone know what room the DC101 talk is? #DEFCON
For the love of god, turn off the sound on your digital cameras when taking a picture in a talk. Heck, do it everywhere else too. #BlackHat
What's the point of having a Q&A at #BlackHat if they're going to blatantly dodge every question and orgs not call them out on it?
Pretty sure I saw Tom Skerritt walking into Caesar's Palace earlier today #BlackHat
@TysonZinn lol showing up. ;) it was a CTF competition, but sadly it was under attended.
Won the Most Offensive Hacker Award. Not sure if that's a good thing. Thanks for CTF setup @madirish2600
