Fake WhatsApp Web pages that link the victim's account to an attacker device, behind Chinese search-engine doorways

family: whatsapp-linked-device-seo-2026-10

Fake WhatsApp Web login pages in Traditional Chinese that show a live QR code or ask for a phone number, so that scanning the code or entering the pairing code links the victim's WhatsApp account to a device the attacker controls. The phishing pages are reached only from search results. A large set of look-alike doorway domains registered in bulk in October 2026, such as webapi-whatsapp[.]com, webhwsapp-whatsapp[.]com and aggregator-whatsapp[.]com, shows search engines an article about WhatsApp Web, sends a visitor arriving from a search result on to a phishing page, and sends anyone else to a search engine or to WhatsApp's real site, so a direct visit shows nothing of the lure. Phishing hosts seen include web.boot-whatsapp[.]com, web.poly-whatsapp[.]com, docss-whatsapp[.]com and gm-whatsappt[.]com. The doorways use the same cloak script as the same operator's fake Google Chrome and WPS Office download sites. A match means a page carrying one of the phishing kit builds or the operator's visit tracker, or a scan of a known doorway server address or campaign host.

One hunt for the campaign. YARA anchor: three builds of the phishing kit, keyed on their own QR-code and pairing-code endpoints, configuration names and page structure, never on WhatsApp's name or artwork, so WhatsApp's own pages cannot match. Search anchor: the operator's self-hosted visit tracker, the doorway server addresses (dedicated to this operator), its tracker hosts and the newest doorway and phishing hosts. The phishing hosts' own addresses are shared with unrelated sites and are not included. A doorway visited without a search-engine referrer ends on a search engine or on WhatsApp's real site, so such a capture is not a negative.
