Firefox to Import Windows Root Certs To Avoid Antivirus SSL Scanning Issues
Uh, no , part of why Firefox doesn't suck is that it used an independent certificate store. sucking in the windows cert store is asking for trouble.

Colm MacCárthaigh on Twitter: "Client certs and Mutual-Auth TLS is TERRIBAD."
I never really thought deep about client certs, but this makes a real case for why they actually suck, and possibly suck worse than anything else before...

LAteral Movement Encryption technique (a.k.a. The "LAME" technique)
I wonder why let's encrypt didn't isolate the internal IP range DNS entry SSL certificates to a child CA cert that enterprises could explicitly distrust, which would quash this in a heartbeat.

Signed Malware
Implies the codesign certs and private keys leaked, which would be the older SHA-1 type that used files/exportable keys. That, or people using the newer dongle based SHA-2 codesign certificates were leaving the dongle plugged in, someone infiltrated the malware to be signed, performed the signature, then exfiltrated the signed malware back out of that company's build environment.
