steganography malware

The steganography malware tag covers security reporting on malicious software concealed inside seemingly ordinary files. Its current focus is StegoAd, a campaign in which 119 Microsoft Edge extensions reportedly hid malware in image and font files. Microsoft removed the extensions from its browser ecosystem after the add-ons may have reached up to 2.6 million installs. This coverage examines how browser extensions can create supply-chain and desktop security risks, even when distributed through official stores. It also highlights the role of permissions, telemetry gaps, and the browser’s growing importance as an operating environment in detecting and containing threats.
