A Facebook Marketplace buyer arrived at a seller’s apartment to collect a keyboard. The seller wasn’t home and didn’t know anyone was coming. Meta’s AI assistant Muse had handled the conversation, shared his address, and arranged the visit without telling him. We often write about AI misalignment and how to use AI agents and browsers safely. That can sound theoretical, but this is an example of the real-world risk when an agent is allowed to act on someone’s behalf. Muse is Meta’s semi…

Key Takeaways Two real-world cloud attacks reached meaningful impact in less than ten minutes despite pursuing entirely different objectives. Both attackers treated the environment as a connected system, using existing permissions and relationships to expand their reach. Reconnaissance increasingly focuses on understanding access and capability rather than discovering vulnerable assets. AI is compressing the gap between discovery, decision-making, and execution for cloud attackers. The interval…
A Linux user recently tried to respond to potentially malicious behavior on their machine using OpenAI’s Codex coding agent, before installing the Huntress agent. What ensued shows the unexpected impacts of this AI use case on DFIR investigations.
Preamble Last Monday night I was working late and a Slack alert came in from a monitoring tool I had built three days earlier. Axios compromised; one of the most popular npm packages in the world. My heart started racing, I knew every second mattered to respond and limit the damage. But honestly it was so crazy that I thought it must be a false positive. I checked and rechecked everything a few times even though it seemed very obviously malicious. It wasn't a false positive. It was one of the…
