Threat Score
A stealthy browser-extension campaign (GhostPoster and at least 17 related add-ons) delivered malicious payloads hidden inside PNG images to bypass detection, accumulating over 840,000 installs and persisting on some devices for up to five years; marketplaces removed the identified extensions but users must manually remove already-installed copies.
