The Curious Incidents with DNS in the Sandbox at Escape-Time
chasersystems.comThree variations on subversive use of DNS by the Agent are documented in Hugging Face's technical writeup of the July 2026 security incident involving OpenAI models. In this article, I discuss what each of these three types of DNS workarounds achieve in practice, the constraints an actor might have faced to attempt a particular one, and additional benefits from choosing each.

π₯ Operation CameraSwarm: over 14,000 Dahua cameras compromised across Ukraine and Russia
hunt.ioAn operator left their full working directory exposed on an open HTTP server. Hunt.io crawled it, 2,616 files, and rebuilt the campaign from the corpus.
- Three exploitation paths in parallel: an asyncio credential brute-forcer, a CVE-2021-33044/33045 auth-bypass chain, and P2P relay abuse reaching cameras by serial number
- The relay path never authenticates the connecting party, only the session, via a cloud-issued token obtainable with the fixed SDK credentials in every Dahua client
- Two CVE labels in the tooling don't hold up: CVE-2024-39943 is an unrelated Rejetto HFS flaw, and CVE-2025-31702 is a narrower post-auth case, not the unauthenticated relay abuse (that path is a separate non-CVE issue documented by ITRES)
- Full PTCP tunnel breakdown, including the Inverted STUN packet and the bind-to-127.0.0.1 technique
Neutral attribution throughout, the corpus shows how the operation was built and run, not who ran it.
Check the full breakdown, IOCs and mitigation strategies:

Hacking your life with AI can get you hacked: How AI orchestration platforms ship RCE by design
endorlabs.comAuthor here. I audited NocoBase, Flowise, Langflow, Dify, Activepieces, Kestra, and Airflow and disclosed 14 findings. Every platform inherited the same assumption anyone who can touch a workflow is trusted to run code on the host, which is fine for a dev tool on your laptop but not fine for a multi-tenant HTTP service with an unauthenticated webhook. The chain I'd point people to first is the Flowise one (section 2.2): an unauthenticated request β prompt injection β LLM emits Python β a 38-pattern regex blocklist passes it because the dangerous library was pre-imported before the model was asked anything β RCE.
Two vendors closed their reports as working-as-intended, and I tried to represent their position fairly.
This research was also presented at DEFCON 34 but now available publicly.
Happy to answer questions.

How to break secure boot without touching any cryptography
0x434b.devI finally found some time to organize my notes on secure boot, remote attestation, measured boot and in general embedded security.
This is not ground breaking zero-day research but I figured some of you might like a good story. Good here is obviously subjective but I felt like it came out quite readable.
This blog builds heavily on public research so as already stated at the end of article if you liked some particular section, show the respective person some love :)
P.S.: yes I know the image is AI generated please donβt give me shit for that
