Perhaps developer and Redditor UntilHEX should have sensed the crypto miner’s presence without AI help, as they admitted the malware’s presence “explains why my Mac has been running like s**t”. Claude caught a cryptominer on my Mac whilst building me a temperature monitor app from r/claude Ironically, the cryptomining malware’s nefarious CPU cycle hogging activity is what may have led to its discovery and demise. Pondering over a screenshot of the Claude Code window, we see that this malware was probably added to the Mac’s startup roster on August 29. It looks like UntilHEX was inspired to develop a Mac temperature monitor app after this infection to track and diagnose why the computer was running so hot. Claude stepped in after the Redditor was concerned about a dump of the Mac’s raw temperature sensor readings. “They seemed far too high,” commented UntilHEX in the social media post. Indeed, the well-known coding agent pointed out that the CPU was peaking at a very toasty 112 degrees Celsius.
