At 2022, and I presented “Lamboozling Attackers” on how you can leverage deception environments to exploit attacker brains (i.e. their learning & decision-making). Slides are now online here and they are An Experience: swagitda.com/speaking/Lambo
A screenshot of our slide deck. The title is Lamboozling Attackers and our names and Summercon 2022 are at the bottom of the slide. The background is a turquoise lagoon at the base of a waterfall, waterfall foamy and enticing and glittering in sunlight. There is a spectacular rainbow arcing across the top third of the slide, hitting the tropical water at the slide's edges. The transcendent scenery inspires hope, enchantment, and a bit of whimsy.
A screenshot from our slide deck. It features a Sun Tzu quote, which says "Hold out baits to entice the enemy. Feign disorder and crush him." The background is of a beach where a lavish, foamy wave is mid-crash upon the sandy shores, which look lavender in the light of dusk.
A screenshot of our slide deck. The text says: Systems terraforming: reify an entire constellation of hosts upon connection. The background image is of the Milky Way as seen from Earth. There are an astonishing number of purple hues within it -- the purple of bruises, of lilacs and pansies and orchids, of glittering amethysts, just as the stars look so scintillant and shimmering in the photo. The space dust of the Milky way looks nacreous, opalescent while glowing peach in the bottom right of the image. It is impossible not to behold beauty in this image, to not feel like perhaps anything is indeed possible.
A screenshot of a slide from our presentation. The text says: Imagine if software engineers could exploit attackers as much as attackers exploit defenders now! The background image is of a sunny, cloud-painted sky -- as if you can feel the delicate rays warming your face through the screen. But, notably, there is a rainbow lens flare in it the shape of a waxing moon. Such moons represent birth, enchantment, opportunity -- the start of something bigger to come. And rainbows reflect possibility as well, do they not? That something magical and wonderful might be vibrating the very air we breathe right at this moment. Lamboozling is that magic, that opportunity, that inspiration. The overall impression imparted is one of affirmation and encouragement.

It’s kind of amazing that the mathy differential fault attack parts have been automated to “ran his script, and all the keys popped out”

is there a more glorious feel than a passion project reaching its well-earned conclusion? I am bursting with pride and can barely bottle my hype, so glittering and effervescent (I am aware this is obnoxiously vague, but all shall be revealed soon…)

Introducing Patrolaroid, a malware scanner for AWS instances that doesn't yeet around your prod. & I made it OSS so ppl don't have to deploy sketchy security tools in prod just for basic coverage of malware, miners, toolkits, backdoors, etc.

I built an open source malware scanner for EC2 with . It takes takes and scans snapshots instead of running on the instances themselves, so it’s much safer than many other security tools. We’re calling it Patrolaroid. Please try it out

What if we had access to additional shift keys, allowing us to argue on the internet with letters that are EVEN MORE uppercase? An exhaustive case analysis in my latest weirdo video: “Uppestcase and Lowestcase Letters [advances in derp learning]”

I wish "competent" wasn't considered a non-compliment by some (they seem to think it means doing the minimum?). Competence, in reality, is incredibly scarce. There is little I respect more than ruthless competence -- efficient execution with a relentless focus on outcomes 🥵

Cydia just joined the legal battle against Apple: "A new lawsuit brought by one of Apple's oldest foes seeks to force the iPhone maker to allow alternatives to the App Store, the latest in a growing number of cases that aim to curb the tech giant's power."
