Been collecting data around bitflips and typosquatting for almost 3 years & recently reached a huge breakthrough in the research / custom tooling with the help of @joohoi so now it’s time for us to massage everything down into a cfp for @BlackHatEvents & @defcon fun times!
Been a year since i had the opportunity to visit Finland for the first time & attend @Disobey_fi (all thanks to @joohoi for gifting me a ticket since they sold out in minutes) what a amazing experience! This year I’m presenting on the Main stage on Friday evening, mind blown!
This looks super nice, and it's going to be open source! (and it uses ffuf under the hood too)

gofore.com/en/disobey-202… The Hacker tickets are now all gone! Such a cool puzzle this year.
I've now completed my Master's studies at @JAMK_fi and will soon graduate as MEng in Cyber Security😎 My thesis "Defending Azure Active Directory: Pass-Through Authentication Attacks and Countermeasures" is published today and is available for download: urn.fi/URN:NBN:fi:amk…

Re: hacker ticket puzzle
Midjourney interpretation of ”group of 4 puzzle creators drinking tears of participants…” It’s _very_ accurate. @Disobey_fi #oispahackerbadge
It's on!
Web UI you said? Nothing more to say #micdrop #reconftw new release, highlights over here ⬇️ Just a big shoutout to the devs of new additions like @n0kovo @hakluke @LC @r0oth3x49 and the web UI creator master @lur1el1 #bugbounty #hacking #recon

Hey you all 1714 Disobey visitors! THANK YOU for attending! Your feedback is important, so please let us know how we did and how much fun you had this year: tinyurl.com/ycxy2uhw #disobey2023
It's easy to get tunnel vision while doing community work, seeing the outcome as it is technically - outside of the context. An important thread, and a reminder to thank all the people who make the difference, the awesomeness would not be there without you ❤️

So, apparently I've managed to achieve all the goals for this trip. What can I say... @Disobey_fi is an event completely different than any other... Just... Fuck yeah, expect me next year #disobey2023

For those wondering wtf this is, it’s a fictional storyline that has been ongoing through several events.

“Remove the noise in your life & focus on what’s important” well that is not as easy as it might seem. Been less active on socials but had a real good year bounty wise. Removed all pressure & approached hacking as a recreational hobby without expectations and learned so much!
