I gave a talk about what changed in attacking and defending GitHub actions and whether everything is safe now a while ago.
If you're interested in slides, they can now be found here:

@github Actions, can make your dev life easier, but they can also get you pwned in no time, if you are not careful!
There haven been some recent changes so @intrigus_ will cover the past and future of attacking and defending GitHub Actions on Thursday, 7pm, CS building room -120.
Congratulations to the winners of this year's GPN CTF:
🥇 "H-T8" (ht8.fi/en/)
🥈 "W4llz" (@w4llz_Team)
🥉 "z0d1ak" (@ACM_VIT)
We hope everyone had fun with our challenges, and we'll see you all again 🚀
We would like to thank our writeup sponsor: @zellic_io
- they hire and apply top talent to the world's most critical security problems, specializing in securing blockchain companies and smart contract protocols.
And finally, no event would work without an infrastructure sponsor: #telemaxx- they are a Karlsruhe-based provider of state-of-the-art data center, housing, managed and telecommunications services for business customers. telemaxx.de/en/
