2024 has been a trip. Microsoft shipped an infostealer as a feature, on by default (Recall), then took down a chunk of Azure one evening, and was still overshadowed by CrowdStrike accidentally causing more harm than any malware campaign ever ($5b+ ?USD in losses). Also, OpenSSH remote exploits! See some of yall in Vegas soon!
EDIT: Also, the whole multi-year con to backdoor xz and sshd on systemd distros (thanks @AlesandroOrtiz )
Secure Boot is completely broken on 200+ models from 5 big device makers:
Great work by the Binarly team and an excellent write-up by @dangoodin!

I'm stoked to announce that @rk and I are speaking at @defcon DEF CON 32 on Friday at 1:00pm. Our talk, `sshamble: Unexpected Exposures in the Secure Shell` covers lesser-known tricks for making remote secure shells into your shells.

Also, DEF CON's deadline for materials is midnight and our servers are working as hard as they can to pull the necessary data.
my favorite quasi-backdoor SSH capability (today) is ""Russia URAL Special Auth Feature""
alias ffssh="ssh -oStrictHostKeyChecking=no -oKexAlgorithms=+diffie-hellman-group1-sha1 -oHostKeyAlgorithms=+ssh-rsa -oCiphers=+3des-cbc"
Today is a big day for OpenSSH patching: https://www.runzero.com/blog/openssh-servers/
Amazing work as always by the Qualys security research team, you can find the full advisory on "regreSSHion" at https://www.qualys.com/2024/07/01/cve-2024-6387/regresshion.txt
The OpenSSH release notes are a fantastic read as well, especially the bits about timing analysis: https://www.openssh.com/txt/release-9.8
Lastly, if anyone else planning to drop SSH zero-day before summer camp, please give me a heads up, it's tough keeping a list of all of the cool research that our talk won't cover 😆
