Two AMAZING talks for the Brisbane Functional Programming Group #BFPG September 9th meetup:

• ​Typed Holes and Hole-driven Development (George Wilson) #haskell #fp
• ​#Gleam's Type-Safe OTP Concurrency: A New Era of Reliable Distributed Programming (Cameron Badman) #erlang #beam #otp

I'm exploring a new idea called FediOTP (codename): an authentication system that uses #ActivityPub DMs to deliver one-time passwords, allowing any #fediverse account to authenticate with web services. Unlike current solutions that rely on specific APIs (#Mastodon, #Misskey), this would work with any ActivityPub-compatible server, increasing interoperability across the fediverse. Would love to hear your thoughts on potential challenges or use cases for this approach.

For those skeptical of DMs in #ActivityPub: I'm also considering an alternative verification approach using ActivityPub's Question feature. Instead of sending numeric codes, the system could send a poll with several emoji options, and the user would select the one that matches what's displayed on their login screen. This visual authentication method might offer better security against certain automated attacks while still leveraging federation rather than platform-specific APIs. Would this approach address some of the privacy concerns around DM-based verification?

New Privacy Guides article 🔑✨
by me:

If you are using a YubiKey,

you might get in some situations where you need to reset your key to factory default, and/or set up a backup of it on a spare key.

This tutorial will guide you
through each step to reset and back up your YubiKey successfully, with clear instructions and plenty of visual support.

I hope you find it helpful!

🚧 Brute-Forcing One-Time Passwords 🚧

My last two threads discussed the probability of brute-forcing OTPs, how to do it effectively and how to defend against attacks.

Here is an overview of the topics covered:

1. Bernoulli Processes 🧮

2. Increasing and Decreasing Probabilities 🤞
https://infosec.exchange/@kpwn/110561329301840527

Here's everything compiled into a blog post 📰
