What happened
The author crawled the Tranco Top Sites list with Playwright, hooking canvas toDataURL calls and navigator.webdriver to collect fingerprinting scripts, and published 1,033 captured canvas renderings clustered by vendor at fingerprint.garden. One canvas traced back to a script hosted at servicepipe.tech/static/checkjs/... which contains obfuscated functions named computeRicinLethalDosageForWaterSupply and calculateDeadlyLethalSuicideAspirinDosage, returning a 'lethal lethality threshold confirmed' summary object. The excerpt cuts off mid-sentence at 'This was all pretty alarming until I asked', so the actual explanation for the names is not given in the text.
Why it matters
If you embed third-party anti-bot or fingerprinting JS on login, signup, or checkout pages, this is a reminder you cannot inspect what it ships: this script was obfuscated with mangled function names and alarming bioweapon-themed identifiers, and the article never resolves whether that is a decoy/tamper-trap or something else. Decide whether you're comfortable shipping obfuscated vendor scripts you can't audit, and if you crawl sites at scale for research, note the Playwright canvas-hook approach here as a working collection method (10,000 sites, 1,033 canvases retained).
Discussion angle
The writeup ends right before the payoff — what do you do when you find a vendor script with alarming function names but no stated explanation? Worth debating whether scary-looking identifiers are a legitimate anti-tampering decoy, and whether that excuse is good enough for code running on your payment pages.
