On this week’s show Patrick and Adam discuss the week’s security news, including:

The SSH backdoor that dreams (or nightmares) are made of
Microsoft gets a solid spanking from the CSRB
Ukraine uses an old Russian WinRAR bug to hack Russia
Push-notifications and social-engineering combined-arms vs Apple
And much, much more.

We have a special guest in this week’s show, Andres Freund, the Postgres developer who discovered the backdoor in the xz Linux compression library.

This week’s show is brought to you by Island, a company that makes a security-focussed enterprise browser. Island’s Bradon Rogers is this week’s sponsor guest and he’ll be joining us to talk about how people are swapping out their Virtual Desktop Infrastructure for enterprise-focussed browsers like theirs.

Andres Freund (Tech) on X: "@binitamshah FWIW, I didn't actually start looking due to the 500ms - I started looking when I saw failing ssh logins (by the usual automated attempts trying random user/password combinations) using a substantial amount of CPU. Only after that I noticed the slower logins." / X
