I found this! I posted a semi-click-bait-ey tweet about it here [0], I think it’s important for people know how easy these bugs are becoming to find. It’s becoming borderline irresponsible not to audit your internet-facing code with modern AI tools.

Speaking of which… if any of y’all work on security at OpenAI I have some questions for you about Daybreak! Please email me

Every security engineer with access to Daybreak (Red or Blue) has a direct communication channel to OpenAI through an assigned Account Executive, or at least your employer does. If you are independent and authorized to use the model, your best option is to email/chat via the support page.

Nice work! A similar vulnerability in 2019 also found by you included the recommendation to update with:

  apt -o Acquire::http::AllowRedirect=false update
  apt -o Acquire::http::AllowRedirect=false upgrade
Since this also involves redirects, would that protect users while updating apt for this one also?
Re:Debian apt security update (man-in-the-middle) by justicz on Wednesday November 04, 2026 @01:16PM (#50369413)
That sounds right to me, but FYI the APT maintainers themselves are recommending Acquire::Retries=0 as the mitigation since some mirrors might actually have redirects.

I saw the ubuntu announcement also defers to the `apt upgrade -o Acquire::Retries=0` recommendation

Looks like you also found a similarly critical apt bug in 2019: https://lists.debian.org/debian-security-announce/2019/msg00...

Do you think there might be even more still lurking out there?

Re:Debian apt security update (man-in-the-middle) by justicz on Wednesday November 04, 2026 @01:22PM (#50369504)
I do. I think that security-critical but overly complex software like this should be rewritten and certain aspects of it formally verified, since such things are now practical.

HTTPS would have mitigated this particular bug but it feels like rearranging deck chairs on the titanic to fight over that right now. We need to audit everything with powerful AI like, yesterday.

I'm sure Debian was invited to take part in Project Glasswing back at the beginning of this year.

I wonder if all the people who laughed off Anthropic's sensationalistic claims about Mythos as marketing fluff have recanted, or if they're too busy patching, or maybe they're stochastically parroting Ed Zitron's latest blather.

This is also a reason why I'm trusting less and less the companies that strongly push against AI. Especially for SaaS type of businesses, AI red teaming is now a critical part of development process.
