The first AI agent worm is months away, if that -- Dustycloud Brainstorms

The first AI agent worm is months away, if that<br>By Christine Lemmer-Webber on Thu 05 March 2026<br>I'm convinced that the first AI worm/virus is months away, if that.<br>We've seen the first major evidence of "claw" style agents, which have<br>only been around very briefly, acting in highly malicious ways. See the<br>AI agent publishing a hit piece on a FOSS developer<br>series, and also the<br>hackerbot-claw attacks,<br>etc.<br>But the first real hint of an AI agent worm just happened, even<br>though it isn't actually one quite itself (yet):<br>the package cline was compromised to install openclaw<br>with full access, and managed to do so on 4k users' machines before it<br>was detected. (No doubt, openclaw is still running on many of those<br>users' machines without them knowing.) The attacker used a similar<br>title injection attack like one of the ones<br>used by hackerbot-claw,<br>where the attacker performed an injection attack against a PR review agent.<br>It seems that openclaw was installed without specific instructions to<br>do anything in this case. But that won't be the case shortly. Here are<br>my predictions about the first major AI agent worm/virus, and what it<br>will look like:<br>It will happen initialized through an open source project that uses<br>automated PR review or code generation tooling, whether on the forge<br>or on the developer's machine themselves<br>It will happen in the FOSS ecosystem<br>The virus will use local credentials to spread itself across other<br>projects<br>Unlike normal viruses/worms, the resulting virus will be<br>nondeterministic in nature, and thus harder to detect, and will<br>likely switch between techniques on each outgoing attack<br>My best advice to FOSS developers is: don't rely on agent based coding<br>or review tools. Those who are will be the first line of users attacked.<br>And you don't want to be part of that story.<br>Once the first LLM based virus takes off in the FOSS world, it will<br>spread to other domains. But open source devs: it'll happen in our<br>backyard first, and if you're relying on nondeterministic code<br>generation or review tools, you'll be vulnerable to kicking it off.<br>And note, I said kicking it off. Because there is a high chance that<br>once this happens, it's going to backdoor itself into many other<br>systems that didn't opt in to AI agents.<br>We're gonna have a "fun time" ahead. Capability security<br>(like the kind we advocate at Spritely)<br>can help, but only so much. Wrapping agents in sandboxes is tough to<br>do, since AI agents are fundamentally confused deputy machines, and<br>will mix whatever authority they are given.<br>Fun times ahead...
