Researchers Find 108 Malicious Chrome Extensions
A security research team at supply‑chain security firm Socket discovered 108 malicious Chrome extensions that have been downloaded more than 20,000 times. The extensions, linked to five operators (Yana Project, Game Gen, Side Games, Rodeo Games and Inter Alt), inject unsolicited advertising across visited websites and exfiltrate user data to a common command‑and‑control server, suggesting a coordinated campaign. Identified add‑ons span categories such as YouTube/TikTok web clients, games, Wi‑Fi speed tests and translation tools. The researchers found 45 extensions with a universal backdoor that opens arbitrary URLs at browser start, 54 that steal Google account identities, and one that transmits Telegram session data every 15 seconds. Socket recommends users remove any of the listed extensions via Chrome’s Extensions manager and publishes the full list on its site.
Malicious browser extensions that inject ads and steal identities can distort ad metrics, enable ad fraud, and undermine user trust and privacy—affecting publishers, advertisers and measurement in the ad ecosystem.

Microsoft exposes 'StegoAd' malware in browser extensions
Microsoft disclosed a sophisticated malware campaign called “StegoAd” that infected 119 browser extensions since 2021 and was installed up to 2.6 million times. The attackers used steganography — hiding malicious code inside seemingly harmless PNG images — to deliver payloads days after initial extension installation. The malware replaced affiliate links, stole cookies and session data (enabling account takeover), downloaded additional tools aimed at stealing Google and WordPress credentials, and could enable remote control of infected devices. Microsoft removed all 119 extensions from the Edge add‑on store, suspended over 90 developer accounts, and shared technical details with other browser developers (including Chrome and Firefox) to help detection and mitigation.
Backdoor in WordPress Plugins Hits 400,000 Installations
A backdoor hidden in more than 30 WordPress plugins has been discovered by web developer Austin Ginder. The plugin collection was originally developed by WP Online Support and reportedly sold in early 2025 to an anonymous buyer using the nickname “Kris,” who renamed it Essential Plugin. The malicious code—activated in early April 2026—injected spam links, redirects, fake pages and crypto links that pointed to public blockchain endpoints; changes were crafted so only Google’s crawler could see them. Essential Plugin reports the affected extensions had over 400,000 installations. WordPress has removed and disabled the extensions from the plugin directory. Users who installed any of the listed plugins are advised to remove them or apply a patch published by Ginder and to audit sites for unauthorized changes.
Litter Robot leverages TikTok Shop without discounting
Whisker, the maker of Litter Robot, has joined TikTok Shop to secure early adoption advantage and reach younger demographics like Gen Z and Gen Alpha. Despite being a high-consideration item at $699, Litter Robot found success on TikTok Shop due to its visually appealing self-cleaning features, which act as a 'thumb stopper.' The company maintains a firm pricing strategy, avoiding aggressive discounts typical on the platform. It also focuses on gaining first-party data by onboarding TikTok Shop customers to its app and carefully scaling its affiliate program with niche content creators. The brand anticipates a halo effect driving sales across other channels like its DTC website and Amazon.
