What happened

  • CIAD-2025-0055 says attackers send “Hi, check this photo” from a hijacked contact, lead victims to a fake Facebook viewer that asks them to “verify” with their phone number, and abuse WhatsApp’s “link device via phone number” pairing-code feature to add the attacker’s browser as a hidden linked device, with no password theft or SIM swap. The hijacked account then messages the victim’s contacts.
  • Root cause: social engineering of the pairing-code flow.
  • Attacker: unnamed criminals.
  • Response: check Settings > Linked Devices and log out unknown devices; never enter your number on sites claiming to be WhatsApp or Facebook.
