We found a new vulnerability in TLS. It's a variant of the ALPACA attack that bypasses current countermeasures. Relativly low impact - but great insight! Check it out: opossum-attack.com

I dont think so - but from scanning the document i don't think its upgrading within a connection but only impacting future requests.

Oof. Reportedly, if you got a certificate from SSL.com by putting "example[@]gmail.com" at _validation-contactemail.example.com, they would add gmail.com (!!!) to your verified domains.

A good reminder to use the CAA record, and to sign up for CT monitoring (e.g. Cert Spotter).

doing this I indeed found some bugs and other inconsistent behavior of our libraries - it really added some amount of value besides the obvious

Does it do everything right? no. Is it good a writing bug free code? no. Is it good at writing the code where everyone knows how its supposed to look like but somebody has to do it? hell jeah - reviewing such code is so much faster than writing it.

I spent the last few weeks playing with Claude code to refactor our codebase, add tests and documentations - and I am kind of impressed how useful it is. For 125$ I reached >97% code coverage with full javadoc for every function in one of our projects.

Tbh - feels bad to deactivate my Twitter account - but at some point one has to choose a side.
