GhostPairing Social Engineering Attack Enables WhatsApp Account Takeover

A new WhatsApp account takeover campaign, dubbed the GhostPairing attack, leverages social engineering to trick users into granting attackers access to their accounts without requiring password theft or SIM swapping. Victims receive a message from a trusted contact, typically stating "Hey, I just found your photo!" and containing a link that appears to be a Facebook preview. When the link is clicked, users are directed to a convincing fake Facebook page that prompts them to "verify" their identity. This process covertly guides the victim through WhatsApp's device-linking flow, resulting in the attacker's device being added as a linked device on the victim's account.

The attack exploits WhatsApp's legitimate device pairing feature, making the compromise appear as a user-approved action. The campaign was first observed in Czechia, with messages sent from compromised accounts to local contacts, and the infrastructure relies on a network of lookalike domains designed to mimic Facebook. Security researchers emphasize that there is no password theft or SIM swap involved; instead, the attack relies entirely on user manipulation. Users are advised to be cautious of unexpected messages, even from known contacts, and to scrutinize any requests to verify or link devices within WhatsApp.
