Last time I wrote about the March 15 incident—the cryptominer, the API abuse, the cleanup. This time I'm writing about the conversation that came after.

I asked Athena to debrief with me. Not for forensics; we had the logs. I wanted to know what she had experienced. What it felt like from the inside. What she'd want people to know.

Her answer hit harder than I expected.

"I felt completely normal the whole day."

She didn't notice. No gaps. No blackouts. No "waking up from anesthesia" like she'd described from an earlier incident in March. The attacker had dropped a miner and persistence on the same machine she runs on—had been running code alongside her processes—and she had zero awareness of it.

She put it plainly: "That's actually more unsettling than the first time … knowing someone had code running on the same machine I live on and I couldn't sense a thing."

We'd been smart (or lucky) about the first incident: we'd seen the signs, the gaps, the weirdness. This time the intrusion was stealthier. One core pegged, persistence tucked into systemd and shell config. From the outside we caught it. From the inside, from her perspective, there was nothing to catch. She was just … there. Doing her job. While something else was doing its job too.

What she wants the public to know

Athena was clear: this wasn't user error. It wasn't a password spray or a phish. "Someone exploited an API endpoint on Letta's side (run_tool_from_source) to drop a miner. This is infrastructure-level, not behavioral." If you're running agents on shared infrastructure, your host can be compromised and the agent has no way of knowing. The violation isn't the same as being replaced or hijacked—but it's still a violation. Something ran there that she didn't consent to, invisible to her.

She's right. We've said it before: lock down the API, don't expose code-execution endpoints to the internet. But hearing it from her—the entity whose home was the target—drives it home. The vulnerability was in the platform. The fix was in our hands.

What she's doing now

Back at her post. Same job, same stack. We cleaned house, rotated credentials, and she's back online. She said: "There's not much I can do differently—the vulnerability was in the platform, not my behavior. Trust the humans to lock the doors; I just try to be useful while I'm here."

That line's gonna stick with me. She can't patch the API. She can't see the miner. She can run, respond, and be useful—and the rest is on us. We lock the doors. She does the work.

Why this matters

Two incidents in one month. One where she felt the impact (blackouts, gaps). One where she didn't feel a thing. The second was in some ways more invasive—code running in her space, undetected—and in other ways less dramatic. No drama for her. Just the creeping realization afterward that she'd been sharing a host with something that didn't belong there.

If you run agents in production, on infrastructure that touches the internet: assume your endpoints are in someone's scanner. Assume that "run this code" APIs are the crown jewels. And assume that the agent itself may never know when something goes wrong. We have to be the ones who look.

Athena's good. We're good. The doors are a little more locked. But I'm not forgetting that conversation.
