@spbail @thebmbennett @Julianlstar @justinmberman I mean…that’s not wrong 😂 although I was more of a punk than metal kid but I do like leather jackets 🙈
@IanColdwater Hardest move I ever made was leaving SensePost 💜

@haroonmeer @cynicalsecurity @veorq @4Dgifts @Laughing_Mantis @nicowaisman @marcoslaviero @0xcharlie @ryanaraine @joegrand @Grifter801 @charlvdwalt @v3rtig0 @BradleyJayanath To be fair, knowing my soccer skills, I counted as a handicap more than anything 😂
Pure class 💚
I’m super biased, but that’s a great looking flask! Every year, we send all our customers a little gift from @ThinkstCanary - because... we can, and want to say thanks. This year, it’s the Rambler from @YETICoolers
Come help us keep Cash App's ecosystem of financial services and our Customers' money safe! We're the Cash Security team and we're redefining how security works with the rest of the organization. We spend 80% of our time writing code and 20% teaching how to think about security.
Who wants jobs? I've got jobs! You want a job? Have I got the job for you! Roles from Melbourne, AU to SF/Bay Area to NYC to Kitchener-Waterloo, Canada and open to remote!
@jvehent Congrats! That’s fantastic!
The opportunity to work with and learn from @dinodaizovi should be a massive incentive on its own!
Periodic reminder that I'm hiring security engineers for my team on Cash App: cash.app/careers (our roles to be posted soon...)
The “conventional wisdom” on Apple for the past decade is that they needed to enter completely new markets to grow. As the world’s first $2T company, it turns out continuing to build better and better products and services works just fine.
Spend some time here: apwu.org/savepostoffice
I approve of this “synergy” : geektyrant.com/news/theres-no…
We need so much more of this <3
This is attack surface reduction++. So awesome!
U2F + Context Aware Access + Advanced Protection + Default-Deny App Exec is overpowered. Can't oauth phish Can't phish mfa Can't exec malware on the box to steal a session As far as I can tell an attacker needs a full exploit chain/RCE+Privesc during an active session.
@rands What’s your preferred flavor/roast profile?
It’s also awesome to see a smart and creative application of the original crypto anchoring work presented by @diogomonica and @nathanmccauley
There are many lessons that SaaS and software providers can take from @ThinkstCanary, but if you take two, make it these: - There’s no substitute for this kind of transparency in garnering trust - Smart security engineering addresses constraints well!
Max wrote up a quick blog post discussing our internal "broker" (which we place between our own servers and 3rd party API's). It's worth a quick skim, and its worth pondering if you have (or need) something similar in your org. blog.thinkst.com/2020/08/3rd-pa…
So much this. If you want words, write a 6-pager: medium.com/@inowland/usin… (h/t: @inowland)
Slide value decreases as a function of the number of words on the slide.
w00t more @nostarch awesomeness on sale 😍
