This is not a breach of the GitHub systems or the GitHub infrastructure or how GitHub stores files - it's just that GitHub's code on GitHub some of the stuff that was supposed to be private got downloaded. In the end, GitHub found, I think, that there are only three stolen certificates that were actually still valid, in other words, that crooks could actually use for signing anything.

We've got one zero-day, but perhaps even bigger than that, we say, "Thanks for the memories, Windows 7 and Windows 8.1, we hardly knew ye."

LastPass finally admits: Those crooks who got in? They did steal your password vaults, after all. Actually your passwords were encrypted, but the websites and the web services and an unstated list of other stuff that you stored, well, that *wasn't* encrypted.

Microsoft now has an advisory out that's blaming rogue partners. The problem with certified kernel drivers, of course, is because they have to be signed by Microsoft, and because driver signing is compulsory on Windows, it means that if you can get your kernel driver signed, you don't need hacks or vulnerabilities or exploits to be able to load one as part of a cyberattack.
