🇨🇦 I tweet about physical security and pen testing - no personal opinions, how my day went, or other extraneous fluff.

@thesl3ep And the same default admin password lol (oh wait that part's already partially true)

Thank you to everyone who came to my biohacking talk at HOPE XV! It was a very great opportunity for me to talk about a community near and dear to my heart for several minutes.

[Bill Graydon @access_ctrl]

I uh... need to get better at tweeting when I'm going to be speaking. I'll post the recording link when done!

[Physical Security Village @physsec]

Did you catch @access_ctrl and @efeyzee's talk on the Flipper Zero? If you're a time hacker you still have a chance!

[Bill Graydon @access_ctrl]

TIL that "talk show" style camera setups are not optimal for doors! Great hosts and very impressive setup behind the scenes though!

In other news I need to get better at tweeting out farther in advance of things...

[Bill Graydon @access_ctrl]

For those at @ekoparty I'll be giving a talk at 1600 ART on RFID hacking! It's a pretty basic high level overview but a bit of new research! En ingles y español.

If you review the in-plane safety information, you can see exactly where the PSV staff are sitting on this flight.

[Bill Graydon @access_ctrl]

@LockeFang Keanu is totally safe here assuming the shooters are allied. None can fire without the bullet continuing and harming the opposite shooter. Terrible target acquisition here.

#safecracking #Yeggs entered an empty building next door, then passing through the wall into your target. The #safecrackers then made off with the safe that contained $1 million in merch from the jewelry shop.

@thesl3ep reverse permute me harder baby

[Bill Graydon @access_ctrl]

@brianhalbach ... hack... the orb!

[Bill Graydon @access_ctrl]

@rixon @defcon Sure do! These are all the OG RDTs, COVID was late to the game on the same tech. They're mostly used in the developing world though where more accurate lab testing is harder to access.

[Bill Graydon @access_ctrl]

It's official: what happens in Vegas, stays in Vegas! Surely the sign of a successful @defcon

[Bill Graydon @access_ctrl]

@shortRound5454 @defcon Yeah valid point... more like 30 to be on the safe side for RDTs. But I had to hop on the "post ur covid test" bandwagon while it was still hot after DC.

[Bill Graydon @access_ctrl]

Friends at DEF CON right now - the PSV crew is gonna be doing a small party tomorrow at 22:00 in one of the nice Bally's (Horseshoe) suites, got lots of food and beverages. DM me if you're interested (even if we've never met before!) and I'll let you know the room # and details!

[Physical Security Village @physsec]

Our village talk "Flipping Locks: Remote Badge Cloning with the Flipper Zero" by @sh0ckSec and @_BadCharacters is SUPER popular!

Due to the demand (and huge line outside the village trying to get in), they'll be giving their talk again TODAY at 4:30pm!

[Brian Halbach ☕️ @brianhalbach]

Come hack some door access systems with me at Defcon’s @physsec

[Bill Graydon @access_ctrl]

@thesl3ep Now hotel security is gonna enter rooms unannounced to check for *furniture*

[Bill Graydon @access_ctrl]

@d1dymu5 ... then I guess you can slip under the rader and stay in that case. In either case, it protects the victims, gives the goons the necessary tools to do so, and serves its purpose. Given that, things like facial recognition or other privacy incursions aren't justified. (2/2)
