Berlin Bassline Brief #6: No more Fables, JetBrains plugin badness, macOS stealers, macOS malware detection
JetBrains 3rd-party plugins stealing keys, macOS infostealers in deceptive installers, domain-specific macOS malware detection research, iOSWorld benchmark, and agentic app security at WWDC 2026
"We do not lack for knowledge of what to do for our future security. The lessons of history provide plain guidance."
Since the npm project is taking actual steps on the path to not being the most tedious story in security anymore (https://github.blog/changelog/2026-06-09-upcoming-breaking-changes-for-npm-v12/) the US government has stepped up to the plate, meaning that I'm already tired of discussing the Fable withdrawal and it just happened five days ago. It feels silly giving a serious analysis of an unserious pretext; what else is there to say?
