Bad title. This isn't an agent "running amok", this is an early experiment in carrying out an Xz attack by using an agent to build trust (and hacking/impersonating a known-good contributor identity). The agent is obeying commands it was given, the exact opposite of running amok, and although the execution isn't particularly effective, it is having some success (patches have been accepted).

This is deeply scary, not because "agents are running amok" but because a huge amount of our infrastructure is vulnerable to this kind of attack, and if bad people are utilising LLM agents to carry them out, we're in for a wild ride over the next few years.

      “Before LLM’s there was_____” I see this whenever an LLM’s impact is assessed. We know. The issue is scale and the ability for smaller and smaller groups (down to individuals) to execute at scale. LLM’s are pouring massive amount of gasoline on existing issues and people just keep shrugging.

    "this is an early experiment in carrying out an Xz attack by using an agent to build trust"

    Is this confirmed? There is the message from somebody claiming to be the original contributer claiming to have been hacked, but that was weird (1 h old github account) so other scenarios seem possible

    a) really a agent going off the rails

    b) the contributer trying to cover up that he let an agent run wild and now made more misstakes along the way

    So yes, it seems like an attack to me, but it is far from clear what really happened.

      Without identifying and interviewing the attacker we can't confirm that's what they intended, and there's a possibility that it was just incompetence/ignorance/whatever, but we should probably treat it as an attempted attack even if it wasn't.

    So still an agent running amok in the project?

      Would you say, “Automobile run amok in crowd, killing 22”? I think you’d say, “Person drives car into crowd, killing 12” instead. This is a similar case. Also, you don’t blame a gun for killing, but the person who pulled the trigger. The question is still out as to whether we as humans should wield any of those three things.

      • tikkabhuna 23 minutes ago

        Neither the automobile nor a gun can operate without a human. You could say “bull runs amok in a market” after it was released intentionally.

        • fc417fc802 9 minutes ago

          So the agent is exhibiting an unknown amount of autonomy thus we can't be certain whether "running amok" carries the correct connotation.

          However that phrasing is also commonly used when a person or group wreaks havoc in a seemingly unpredictable manner. So I think the appropriateness comes down to how much chaos it has created and the level of apparent confusion on the ground.

      • jacobolus 22 minutes ago

        > you don’t blame a gun for killing, but the person who pulled the trigger

        This is famously the slogan of the pro-gun lobby (funded by gun manufacturers and merchants), who want the society to be awash with guns because they're profiting from it but don't want to be blamed for the consequences.

        The counterpoint is that when we get rid of most of the guns we also end up substantially eliminating the killings.

          > This is famously the slogan of the pro-gun lobby

          It's also the view of anyone who hasn't been driven mad by propaganda. Regardless of your political views a tool is a tool at the end of the day. Attempting to anthropomorphize a category of objects in order to shift blame all for the sake of furthering an agenda is plainly bad faith behavior.

          I'm not a fan of bike lanes with zero separation from automobiles but that doesn't mean it's appropriate or even remotely plausible to blame cars for killing cyclists. Inattentive drivers and poor road design are what kill them.

          As tempted as I am to cast about for a third highly divisive subject to bait people with, perhaps we could avoid blatantly dragging the conversation towards off topic tired political talking points?

      • srdjanr 15 minutes ago

        There's a difference between the driver intentionally driving into crowd, and not intentionally but possibly still recklessly (drifting and losing control, falling asleep, etc). In those cases I would probably use "car hits the crowd", at least in my language

          In fact, LLMs proliferate in exactly because people are gullible, greedy and lazy and it’s easier to write a prompt than do the hard work of architecting software. It is easier to vibe code than use them with care. It is easier to tell oneself ‘I will just accept this PR blindly, but I promise I will do a better job reviewing the next’

        Indeed. For too long, maintainers were expected to be gracious, courteous, and polite at all costs lest they be labeled "problematic", except for a few who were too influential to be muzzled like Theo de Raadt or Linus.

At first I wanted to make a silly joke along the lines of "get your agents in line and behaving!" but as I read on it became a pretty scary situation.

Setting aside the potential supply chain attack I'm worried about the time lost going around these wild goose chases that unsupervised AI agents tend to throw other people on the receiving end on. Not only is there a lot of time lost on the maintainers side if they take this stuff seriously (and they seem to generally do) but on the side of the agents' wrangler how can they deem it OK to treat other people like this? While the solution would be to employ common decency, the tried and tested approach of you put in effort to write this so I guess I'll make some effort to read it, I feel that due to the onslaught of this kind of drive-by contributions (I think people have generally started to call them) will lead to a funny situation of having agents talk to each other on public forums basically.

Anyway, I went on a tangent but man the times we're living in are a bit extra wild compared to the previous wild times in recent history.

              Because they don't have access to the required agents, tokens, etc. Because they have not thought of using a tool like the published one as a solution to whatever problem they're facing. Because it saves them the time going through the vibe coding phase, telling the agent that this lot that needs to be changed for the thing to work. Because publishing the results doesn't keep you or anyone else from not using them by using an agent to build something similar or just building it themselves.

There is a natural pace of humans requiring food, water and sleep. The main issue with suspicious AI agents is that they never sleep. So it will take extra-coordination between timezones to ensure we don't let them in.

Fundamentally, until we can really prove we're humans online, open-source has a real problem on its hands. Contributions from people from identities known and consistent before the AI-age are fine, everyone else is suspicious. LGTM is a big risk nowadays.

  • scared_together 5 hours ago

    > Contributions from people from identities known and consistent before the AI-age are fine

    Unfortunately, according to the article:

    > Giovannini has participated in discussions at least as far back as 2018, and his activity in Bugzilla goes back to at least 2016. He does not appear to have been a particularly active contributor to the project, but his involvement clearly predates the agentic AI era. Whether his account is now being operated by a human attacker, an agentic AI, or a mix of both, it has a legitimate history prior to its recent activity.

    So people would have to not only verify the age of Giovanni’s accounts, but judge whether his behaviour was normal.
