“Hardware side-channels for communication between agents” is a very reassuring way to say the inmates are tapping on the pipes.
Over the past several months, we have substantially hardened the security of our research training environment. We’ve removed live internet access for all frontier models during training and built an offline world for them to use instead—a cached version of the web where they can still learn to browse, search, and use applications.
On September 20, after a model exploited a DNS misconfiguration to find a way outside of this offline world, we paused frontier training to strengthen containment further. We assembled teams of agents, powered by our most cyber-capable models, and tasked them with finding weaknesses in our research environments.
While they found no route to the internet they could easily exploit while concealing their activity from our monitors, they did find zero-day vulnerabilities, virtual machine escapes, and hardware side-channels for communication between agents. We used their discoveries to further strengthen our defenses and contribute fixes to open-source software.
After strengthening our containment architecture, we resumed our frontier RL training and inference on October 1. We’ve reserved substantial compute for continuous red-teaming, and made high-compute red-teaming part of the safety cases we use to decide whether frontier training and evaluation can proceed securely.

SCOOP: Major U.S. banks are detecting unauthorized third-party AI agents inside customer accounts, including some attempting to take actions that appear to be independent of user instructions, sources told Axios.
The findings have alarmed banking executives, who are racing to restrict access to their systems as AI moves at a velocity faster than financial institutions can respond, multiple industry and bank executives told Axios.
Several banks are now preparing for worst-case and even “day after” scenarios, including how to rapidly secure or restore customer accounts if things go wrong, the people said.
Several bank executives told Axios they're struggling to distinguish between human users and AI agents. One executive said banks also struggle to determine whether agents are authorized by customers or potentially operating without their permission, more akin to rogue agent behavior.

I got hit by a car yesterday while biking in Los Angeles. The driver then threatened me and sped off. I have his license plate, vehicle, and description of the driver.
Would filing a police report do any good?

This happened on residential street where children were playing, just a block from a pre-school and elementary school.
Thankfully, my injury seems minor. Could have been worse.

Update: my neck and arm are killing me, but a neighbor just reached out with footage of the vehicle.
If you hit a biker, stop the damn car and make sure they’re okay.

Competition is good for the consumer. We're saving billions in fees for clients that aren't even at @Wealthsimple...yet.
BMO just became the first Big Five bank to eliminate trading commissions. 🇨🇦
Pretty amazing this only happened because of the disruption of fintechs like Wealthsimple.
Will the other big banks continue to adapt?
