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 😆
