Just updated AuRevoir, a simple app we first released in 2018 that dumps and removes Signal (or other messages) cached in macOS’s notification database.
Free and open source, like all our tools 😇

Apple (copied BlockBlock 👀) and added ClickFix protections… but kept the good stuff private 😤
Reversed xprotectd to see how it really works and emerged with enough detail to build your own (kinda)!

Wow, Apple really Sherlocked a BlockBlock feature literally the same month @patrickwardle released it 😅 x.com/objective_see/status/2…
Just released: BlockBlock v2.4
🆕 Notarization Mode ('All')
Blocks any non-notarized program (even those w/o quarantine attributes).
🆕 Heuristics for 'ClickFix'
Applies heuristics against pastes into terminals, blocking those deemed suspicious.

Motivated by @moonlock_lab’s recent findings on ClickFix attacks surfacing via Google Search results and even LLMs 🤯, I’ve added basic protection against most of these attacks to BlockBlock 🍎🛡️
