[RSS] Attacking PowerShell CLIXML Deserialization

https://www.truesec.com/hub/blog/attacking-powershell-clixml-deserialization

Today I'm thinking again about the "Children of the Magenta" lecture. In the late 90s, airlines realized that after going all-in on automation and flight assists in the 80s, they had trained a generation of automation-dependent pilots who were no longer capable of dealing with novel situations in which the automation couldn't help, or failed. Children of the magenta flight path line on the computer.

I'm thinking about it because someone this morning bragged about letting LLMs write the code.

Fun* fact in this video: the 'disposable' vapes thrown away in Britain alone contain enough lithium batteries to make 1.2 Million e-bikes.
I've been independently powering things with vape batteries that I've rescued before seeing this video. Pull out the cell, add a cheap usb charging module and you have a fully rechargeable 3.7v power source. If you need higher voltage you can put them in series and you can even get multi-cell balancing modules for next to nothing if you want to have a few in parallel for more current.
I don't trust them for anything critical, but they're great for low-budget projects as the cells are completely free. My bike lights are all powered by them (one can run a flashing bike light for a couple of weeks' use), as well as various other things that had their batteries die, or that didn't come with rechargeable batteries.
I also only charge them somewhere flameproof, though I haven't had any issues so far.

Please help us test OpenSSH ahead of the 9.9 release, due in a few weeks.

New features include a new post-quantum key exchange based on ML-KEM, improved controls to disallow unwanted connections and better performance for the existing PQ key exchange.

God this is fucking incredible. Please take my word for it and read

TBF I face much more challenges saving data _from_ the WaybackMachine using the CDX API than most of the sites I've scraped:

Most tools for offline archiving simply don't work, and although I'm *really* slow with my requests I get throttled all the time :P

Oh, and I almost forgot that it's surprisingly hard to translate IA URL's to local file paths, esp. since the URL's retrieved from the API aren't properly encoded (https://web.archive.org/.../http://example.com/...)

Huh, TianfuCup website cert expired: https://www.tianfucup.com

About once in a year I have to look at some Ruby stuff, and it's always getting worse.

Not only can't I install fresh versions with rbenv anymore, but even the ones that are available are broken.

More ranting, as a result from a conversation I had with a couple other #fuzzing people:
