PayPal has blocked our business account and is holding $1.3M for more than 2 months without explaining what exactly they are not happy with. Even @PayPal support doesn't know what's going on. ⚠️This endangers the production of Flipper Zero in general. More details in thread 1/5

Heard the news about @pde33's prognosis and the first thing my scared mind went to was @dakami being gone too soon. Was looking through memories and found this one. These hackers were too good for this Earth, too young to leave it, we still need them, and they are gone 💔…L

Why does every mobile phone company and utility provider need your SSN. Ugh.
I wonder if FOIA requests can be FOIA'ed. There is value in knowing what others are seeking to know.
There is a structure somewhere in ‘the system’, which I don’t yet understand, that’s powerful enough to prevent student loans debt from being reclassified as ordinary loans which can be discharged in bankruptcy.
Our biggest and best event ever! Thank you to everyone who stepped on the mat and participated. ♥️An absolutely incredible experience. Oss.…
Still going ... closing in on 200 endorsements. If you know a CISSP, please talk to them and make them aware.…

It just became substantially harder for Twitter to recruit top security talent.
While they didn't speak, I'd be willing to bet that @elonmusk knew of at least some of the things @dotMudge disclosed. These types of security issues are commonly and widely known to insiders.
#BREAK A former Twitter executive, its head of security, has turned whistleblower.   He alleges grave security problems at the company that he says are a risk to national security and democracy.   His first TV interview here:…

My Twitter is blowing up from this… Let me just say @dotMudge wouldn’t file papers like that unless there were legit serious issues. Twitter’s attempt to paint him as a disgruntled employee is laughable.…

I had a phenomenal time. Many thanks to @jeremiahg for organizing, @Beaker and others for coaching us newbies, @ForrestGriffin and others for the main lessons, and everyone for the great time. Here's to next edition! :-)…

Great time with some of the @IBMSecurity bjj crew tonight! @syndrowm @megan_roddie @_heliuum Thanks again @jeremiahg for hosting!

For an old dude who used to wrestle, you’re damned strong and if you add those skills with some more BJJ, I will NOT look forward to next year! 😂…bq

I’m not here for a long time, I’m here for a weird time.

Thank you @jeremiahg for yet another great BJJ Smackdown. (And thanks @ForrestGriffin for being such an approachable guide, again.) This being the 10th event means I've been to 30%! This got me on the mats back in 2016, and I'll be forever grateful.

@fsmontenegro @jeremiahg You and all the others did great! Learning any new art is a challenge — I see so many parallels between encouraging people to start their BJJ journey and those starting their infosec careers. Patience, empathy, humor, positivity & encouragement. So glad you came!

As a novice in BJJ I was touched at how generous @Beaker and others were by focusing on teaching us newbies, then making sure we could have fun safely. Awesome time. Many thanks to @jeremiahg and others. Looking forward to next time.…

Can’t thank @jeremiahg enough for setting up the BH/DC BJJ Smackdown! Amazing time, probably one of my fav con events ever! Definitely will be back next year.

@6R14N @jeremiahg It was a great time, can’t recommend it enough, see you at the next one!

@Beaker and @jeremiahg. Thanks for the great experience and beating the piss out of me! Definitely the highlight of my blackhat. Humbling and educational.…

I’m pumped, about to get some rolling and jiu jitsu in with @jeremiahg, @ForrestGriffin, and more! Looking forward to seeing everyone on the mats!

Emceeing the CISO Summit.
It begins. Let’s do this BlackHat!
Last call before heading to Vegas! We only have a few spots left! See everyone there!…
It's like everything you buy these days end up sending you a survey email. Annoying.
#Twitter reveals that hackers exploited a new zero-day #vulnerability to expose 5.4 million user accounts by linking emails and phone numbers to them. Read details:… #infosec #cybersecurity #hacking

All vendors, pay attention. While currently a rare occurrence... it won't be for long. The efficacy of your products will be independently measured, evaluated, and judged.…
Consider that cyber-insurance carriers risk their money betting on the effectiveness of a security control stack while most security vendors are unwilling to put their money where their mouth is on effectiveness of the products they sell.
Read this carefully, it's important... and smart.…
Just snagged my ticket for @jeremiahg 's BJJ Smackdown. Of all the events at summer camp, this is easily the one I'm most excited about.

Bankruptcy awaits entrepreneurs who lose the distinction between building what customers say they want and what customers are willing to pay for.
Person: What do you do for a living? Me: Information Security. Person: Interesting! What information did you keep secure? Me: 😳
Twitter’s greatest concern should be that everyone is already looking for the next Twitter to migrate to.
I have no expectation that Twitter will actually do this because it’ll likely kill their “active” user numbers… as they’re likely misleading, and it’ll tank the stock more than it has been already.
Charge an inconsequential amount per twitter account and per tweet. The bot and spam problem will go away. That’s my theory anyway.
The whole domain name registration system is busted and represents an unproductive tax on the Internet. It's gotta be 99%+ of all registered domain names are never actually used for anything.
Only a few spots left! If you've ever been curious about jiu-jitsu, there's simply no better place to try it out. Be amongst InfoSec friends having fun and learning new skills. Whatever your size, age, gender, or physical condition... everyone is welcome on the mat.…
This is one event I will not miss while @defcon. Thanks for putting it together @jeremiahg. Who else is going?…

~23 years of CVEs. Tens of thousands of new vulns published each year. Anyone ever analyze the characteristics of the vulnerabilities that are never exploited?
Excellent! Im convinced security warranties will become the default state in InfoSec. It's the best way to align interests between customers and theit vendors -- and achieve the best outcomes.…
Can't wait to see you again, @jeremiahg! So excited about this event, and about returning to #BHUSA and #DEFCON! Will I see @RSnake there? ;) Please give my best to everyone back at the ranch! So happy for all of you with the wonderful recent news!
