We have some exciting news to share: @blacktop__ is joining Calif to work on a range of R&D projects focused on Apple and AI security. If you work in the Apple security ecosystem, he’s already a household name. He’s the creator of: * ipsw – the ubiquitous Apple firmware analysis tool: github.com/blacktop/ipsw * darwin-xnu-build – reproducible XNU kernel builds: github.com/blacktop/darwi… * ipsw-diffs – automated diffing of Apple releases: github.com/blacktop/ipsw-… * The only public deep-dive on Apple’s Lockdown Mode: github.com/blacktop/prese… His tooling is so good that even Apple engineers use it. If you do reverse engineering, chances are you’ve touched his Rust headless IDA MCP server: github.com/blacktop/ida-m…. People have literally collected CVEs and bug bounties just by digging through the diffs produced by his tools. With @brucedang, @Little_34306 and now @blacktop__, we're building a serious Apple security force at Calif. We’ll have more announcements in this space soon! If you're interested in Apple security, AI, automated bug discovery, reverse engineering, or hacking, we’re hiring: calif.io/jobs.
