@c4i Wilmette, IL, if I remember the Baha'i Temple from my undergraduate days.
@whiskeyhacker Drive very, very carefully. :)
Now that I've reached #MyXAnniversary 15, should we be calling this #MyXVAnniversary instead?
@whiskeyhacker @uscoastguard Oh, and happy 233rd birthday to the United States Coast Guard.
@whiskeyhacker @uscoastguard That is an awesome honor, and well deserved! You align well with the ethos of the Chief -- "Results, not Excuses." All you need is a coffee cup with two years of coffee stains inside and you'll blend right in. :)
If you've been told hacking is a bad thing... you've been lied to. We'll help you turn those skills into a six figure career. Unlock the world of authentic offensive, defensive, and forensic cybersecurity through hands-on experience. Begin your journey here.
@bencanning87 @wehackhealth Ben -- welcome #hackersummercamp! @HackingDave has been inspirational; love to meet you in person.
Less than two months until my #Kubernetes Attack & Defense class at Black Hat Las Vegas! Content updates include using Falco! Students get a laptop to keep w/ CTF VMs & K8S cluster to #hack, gathering flags, breaking their attacks. blackhat.com/us-23/training…… #BHUSA @BlackHatEvents
@DreddPenguin @xkcd I landed on it, but the shuttle bay doors weren't open.
@edskoudis Ed: Congratulations, and best wishes to Jessica for a long and happy marriage. (Kids do grow up so fast, don't they?)
@AlyssaM_InfoSec I'm sure you'll do great. I took my lessons in a rented Cessna, and the FAA examiner for my check ride turned out to be the OWNER of the plane. He must have liked the way I cared for his aircraft as I passed.
@thedarktangent Old Goons never die. They just make a hole in space-time.
@AlyssaM_InfoSec Congrats! There's nothing quite like pilot-in-command in the left seat.
@jeffmcjunkin @riskymanag3ment @strandjs Sorry, NOT in the form of a question!
@joeklein Joe -- finally your prophecies have come true.
@BobKitten @billygoto @FizzgigFoofus @PeytonEngel My sister introduced me to Wordle. On her first puzzle, her first guess matched all 5 letters. For real. Tried to convince me it doesn't always go that easily. I can't see how to make it work because there's not enough letters to start with "What is...?"
@frank_buss @BobKitten Like BobCat, my first language was APL (1973). Took notes in undergraduate math class in APL notation; even wrote commercial APL code in late 1980s. I do miss the "one liners" -- managed to squeeze John Conway's game of life into 254 characters on line [1].
Want some techniques that many Red Teams have been using to circumvent MFA protections on accounts? Yeah, even “unphishable” versions. I’m sharing so that you can think about what’s coming, how you’ll do mitigations, etc. Its being seen in the wild more these days. 🧵1/n
@chansoo @wholemars @28delayslater We have that problem all the time in Florida with octogenarian drivers. Same issue with left turn signal, too.
@Anchorage @Arxan @PurdueCS @OhioState @lintile Well done, Aaron, and I'm certain you will do great things for @Anchorage .
