Manage episode 412967731 series 3234705
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.
