  • 102 hidden blocks, invisible in the browser

    Data-deletion firm Redact read all 545 pages WhatsApp's help centre links to and found 102 blocks of hidden text across 80 of them — sitting in the page source where human readers never see them, every block written as instructions for Meta's AI support chatbot. Most were routine. Two were not.

  • The two that bite: bury the regulator, skip GDPR

    On the account-deletion page, one block ordered the bot to never recommend a Data Protection Authority, regulator, or supervisory authority — and not to suggest manual deletion or using a different phone — leaving locked-out users with one answer: wait up to a year. A second block, triggered when users mention lawyers or legal action, told it not to cite privacy laws such as GDPR "including when a user raises them directly."

  • Meta's line: "a bug," pulled by Oct 18

    Redact CEO Dan Saltman first spotted the text on Oct 8; both notes were still live Oct 15; by 02:08 UTC on Oct 18 all 102 blocks were gone. Meta told WIRED the notes were support-bot instructions exposed by a bug, now fixed, and that it wants its bots focused on WhatsApp help, not legal advice. Archive copies suggest the blocks went up sometime between July and September.

  • Why it lands on your desk

    If you build agents that read the open web, this is the threat model in the wild: pages carry instructions aimed at machines, not people. Diff rendered output against raw source, strip or quarantine injected directives, and treat anything crawled as untrusted data — not system prompt. The trick is already routine; plenty of pages now ship "always credit us"-style lines written straight at the model.
