The fact that @AndresFreundTec didn't just write the whole xz thing off as "It's probably DNS" is honestly amazing.

My next book is *The Internet Con: How to Seize the Means of Computation.* It's a recipe to disenshittify the web and bring back the old good internet. The book is from @VersoBoooks, but the #audiobook is from me - because Amazon refuses to sell it: kickstarter.com/projects/doc… 1/

Every once in a while I'm reminded that dnsmasq, a lightweight DNS and DHCP server that's bundled into *almost every IOT thing and Linux distro*, is a hobby project maintained by one guy in the UK named Simon. Nobody pays him and he doesn't get near the thanks he deserves.

A morning @defcon run with @_cablethief and Jaco to The Mill (for those who remember Defcon at the Riv). Even met @elkentaro on the way.

The RID500 Admin account doesn't benefit from Protected User Group restrictions. This is a MS WONTFIX & means you can authenticate as Admin using RC4 KRB or perform any KRB delegation attack if you impersonate the RID500 Admin. The latest find by @Defte_ sensepost.com/blog/2023/prot…

Struggling to proxy your offensive tools (*cough, Windows, cough*)? See how @_cablethief uses WireGuard and tun2socks to make remote networks available via a network route (from any device or container), over SOCKS! sensepost.com/blog/2022/wire…

Yeah! @defcon wifi fixed this. Plus wpa_supplicant can do leaf cert validation these days too!
Replying to @singe
5/14 If you just validate on CA, then I can buy a DigiCert signed cert, and your wifi client will happily accept that as valid. Defcon's Linux config is vulnerable to this.

A lot of the time, when I have a writing deadline, I procrastinate with code. With LaTeX I can do both at the same time.

assless-chaps now returning NThashes from MSCHAPv2 challenge/responses with the Have I Been Pwned hash set in 0.0's of a second.
Replying to @singe
I just finished the initial rust version (i.e. it compiles, no "did I do it idiomatic" yet) and best measured performance against the full HIBP 20G set is now 0.019s with worst measured 2.147.

I found some design and implementation flaws in Wi-Fi again. All Wi-Fi devices are affected. It was a long ~9 months embargo, over this time a lot of info has been collected and that info now available at fragattacks.com
