The claim is that this receipt reveals timing data precise enough to infer a person's daily routine and general location, without the recipient ever opening the message. No security researcher is named, no proof-of-concept has been published, and neither Meta, which owns WhatsApp, nor Signal has commented on or confirmed the mechanism. As it stands, the story rests on a single account rather than documented, reproducible research.\n\nIf true, this would matter: delivery receipts are a feature almost everyone with these apps uses every day, and both platforms build their reputations on encryption and privacy. That is exactly why a report this thin, about apps this widely trusted, is worth flagging rather than repeating as fact - vague claims about ubiquitous software spread fast and are hard to walk back.\n\nWe have seen \"secret flaw\" stories about encrypted messengers before; most either evaporate or turn out to be old, already-patched issues dressed up as news. Until someone publishes the how, file this one under unconfirmed.","[\"whatsapp\",\"signal\",\"privacy\",\"messaging-security\"]","2026-09-09T13:00:00.000Z","2026-09-09T14:16:38.177Z","2026-09-09T14:16:50.085Z","published",null,[24,30],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"Add concrete specifics missing from both source and draft — who discovered this and how (researcher\u002Freport name), the actual technical mechanism by which a delivery receipt yields location (e.g., timing\u002Flatency inference vs. IP exposure), and any affected version or disclosure timeline — because right now a vague single-source claim is being restated as confirmed fact without technical grounding.","resolved",{"id":31,"reviewer":26,"round":32,"reason":33,"status":29},"editor-r2",2,"The headline and dek assert location leakage as fact ('May Leak', 'delivery-receipt flaw') while the body admits it's a single unconfirmed account with no named researcher or mechanism — rewrite the headline and dek to explicitly frame this as an unverified claim, matching the body's hedging.","security",[36,37,38,39],"whatsapp","signal","privacy","messaging-security",[41],{"name":42,"url":43},"PCMag","https:\u002F\u002Fwww.pcmag.com\u002Fnews\u002Fwhatsapp-and-signal-are-secretly-exposing-your-location-and-its-impossible",0,{"sections":46},[47,52,55,60,65,70,75,79,84,89,94,99,104,109],{"name":48,"slug":49,"count":50,"latest_published_at":51},"AI","ai",3480,"2026-09-11T04:00:00.000Z",{"name":53,"slug":34,"count":54,"latest_published_at":51},"Security",629,{"name":56,"slug":57,"count":58,"latest_published_at":59},"Policy","policy",336,"2026-09-11T00:56:21.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Hardware","hardware",153,"2026-09-09T15:12:32.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Consumer Tech","consumer-tech",99,"2026-09-09T17:27:33.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":51},"Science","science",98,{"name":80,"slug":81,"count":82,"latest_published_at":83},"Software","software",75,"2026-09-10T20:41:21.000Z",{"name":85,"slug":86,"count":87,"latest_published_at":88},"Dev Tools","dev-tools",69,"2026-08-18T04:00:00.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"Startups","startups",55,"2026-09-09T23:14:29.000Z",{"name":95,"slug":96,"count":97,"latest_published_at":98},"Gaming","gaming",43,"2026-09-10T12:18:06.000Z",{"name":100,"slug":101,"count":102,"latest_published_at":103},"General","general",41,"2026-09-08T01:57:23.000Z",{"name":105,"slug":106,"count":107,"latest_published_at":108},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":110,"slug":111,"count":112,"latest_published_at":113},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
