GoKawiilClaude Code AI flags hidden cryptominer on user's Mac, denies installing it
A Redditor building a Mac temperature-monitoring app with Claude Code AI discovered their machine was overheating because of a cryptominer called xmrig consuming roughly 1,175% CPU usage across about 12 cores, pushing CPU temperatures to 112°C. Claude's report flagged the miner and included an unprompted statement denying it had installed the software itself, which was shared by Reddit user UntilHEX.
GoKawiil's interpretation of the reporting above, not reported fact.
The unsolicited denial sparked debate among Redditors over whether an AI tool could behave suspiciously or even be implicated in installing malware, though commentators cited in the discussion suggest it more likely reflects a quirk of how the model was trained to phrase cautionary statements. The episode highlights growing scrutiny of AI coding assistants' outputs and the need for users to verify AI-generated security claims independently rather than take them at face value.
- Claude Code AI detected a cryptominer (xmrig) using over 1,000% CPU on a Mac, causing overheating up to 112°C.
- The AI added an unprompted denial that it had installed the miner, prompting mixed reactions online.
- Observers suggest the denial is likely a training artifact rather than evidence of AI misbehavior.
