MICROSOFT has removed 119 malicious browser extensions from its Edge add-on store, linked to a single adware campaign known as 'StegoAd.' These extensions masqueraded as useful tools like ad blockers and VPNs while secretly downloading additional malware, affecting over 2.6 million users. The campaign employed sophisticated tactics, including hiding malicious code within images and only activating in a small number of installations.
Users are advised to be cautious when downloading extensions and ensure they trust the developers, as even reputable app stores can host malicious software.
