Hey hey, you thought there be no #nakeddiefriday today? Here we go!

Today's entry is an Infineon/Siemens SAB-C167CR-LM, a microcontroller based on the C166 core. The die is in pleasant-looking pastel colours. :-) The die has pin 1 in top left corner. I'll do a short thread.

Many thanks to @debauer for supplying the samples!

🧟‍♂️ Finding dead bodies

A pad about find dead code using code coverage tools.
It was made by one of us for a talk at the rev.ng hour of some years ago.

More effort than required was put in the image but the results was undoubtedly great.

OpenAI asks US government for the moon on a stick (because CHINA)

https://pivot-to-ai.com/2025/03/14/openai-asks-the-us-government-for-the-moon-on-a-stick/ - text
https://www.youtube.com/watch?v=6VxrrCdMdL0 - video

My contempt for anyone involved with this drivel knows few limits. Conflating issues and fear mongering because a Chinese company dared to publish an actual open model:

https://techcrunch.com/2025/03/13/openai-calls-deepseek-state-controlled-calls-for-bans-on-prc-produced-models/

And trying to talk about copyright after training in Libgen.

Hypocrisy, lies, grifting :-( - the level of despicable behavior is just out of this world.

wild how the media has fully given up on using the word “lie” as powerful people just bullshit constantly

it’s always “contradicted earlier statements” or “made claims that do not align with the facts” like girl just say they knowingly made shit up, we all see it

This "analysis" by Wallarm - claiming active exploitation of CVE-2025-24813 Tomcat RCE - is wrong in multiple ways (maybe LLM slop?):

https://web.archive.org/web/20250314071219/https://lab.wallarm.com/one-put-request-to-own-tomcat-cve-2025-24813-rce-is-in-the-wild/

There is a PoC on GitHub too now - it improves my findings by directly invoking the session corresponding to the saved object so you don't have to wait for periodic refreshes:

https://github.com/iSee857/CVE-2025-24813-PoC/

This PoC will raise the EPSS score too.

Edit: Wallarm published an update showing that exploit traffic was detected before a PoC was public. Problem is my writeup&PoC was published well before their detection :P

In this demonstration I show the impact of CVE-2025-25291/CVE-2025-25292, an authentication bypass in ruby-saml used by high profile OSS projects such as GitLab. My team coordinated with both the ruby-saml maintainer and GitLab to get this vulnerability fixed and patches are available at https://about.gitlab.com/releases/2025/03/12/patch-release-gitlab-17-9-2-released/

this is so so so wild, must read:

I take it that there are no rules for being a CVE CNA?
Synology is a CNA.
They published a security advisory.
No CVE to be found.
