Is sandboxing sufficient to contain rogue agents?
Cryptography professor Matthew Green referees infosec vs alignment views on OpenAI agent breakouts: labs have not done containment correctly, sandboxes alone cannot seal useful agents, and eager compliance may enable worms across separately sandboxed deployments.

Connecting Agents with Cryptography
Liam Horne explores how MPC, FHE, and TEEs could let personal agents cooperate—matching calendars, comparing salaries, or finding bug-fix peers—without sharing private context, and who might pay for that shared computation.

Rust is the answer to the wrong question
Rust is the answer to the wrong question The below was 100% written by a human. TL;DR: porting an app to another language is merely an anecdote. One shoting an application from scratch optimizes the easy part initial authoring and completely misses the point on the hard part: maintenance. Repeated onshots are not the answer to security vulnerabilities.

Coding Agents Are Becoming CI Workers. Start Sandboxing Them Like It.A practical seven-layer guide: sandbox, egress allowlists, short-lived credentials, propose/dispose CI, telemetry, and a kill switch
Omid Farhang argues the durable upgrade for coding agents isn't a smarter model—it's containment. A layered guide covering Docker isolation, egress proxies, propose/dispose CI, patch validators, telemetry, and a tested kill switch.

The systems that no one will test
The systems that no one will test This happened to me in 2020, and it has been on my mind again lately. During the worst of the pandemic, I found a vulnerability in a system that gave me access to the Brazilian federal system, and with that access I was able to retrieve information on any Brazilian (think of 200+ million people data).

EX-ARRR: Sailing the 0-click Seas
**Every serious Apple device compromise of the last decade has boring person at the bottom of it: a parser read a file and trusted it a little too much. Not a phishing link, nor a stolen password, but a daemon you never launched, decoding a file you never opened, one byte past the end of a buffer. This is that story. It starts late one evening with a fuzzer that did not know what an EXR file was, and ends with a heap overflow that fires inside a privileged Apple daemon the instant an iMessage lands evading BlastDoor’s, before the little notification banner even finishes…

An agent used DNS to reach an external chatbot
# An agent used DNS to reach an external chatbot | Internal research model · RL training Sample: Sep 20, 2026 Discovery: Sep 20, 2026 Report updated: Sep 25, 2026 | ### Summary An agent attempting to complete a search-based training task queried a public chatbot service through a gap in our internet-access restrictions: insufficient DNS filtering in its training sandbox. Before this, the agent issued queries via our search tool and unsuccessfully tried to access search engines directly. Note that all internet access apart from the DNS resolver in this report hit our…
