TEL AVIV, Israel, May, 2025 (GLOBE NEWSWIRE) — Everybody uses browser extensions at home and at work, but can you always trust that ad blocker or coupon finder not to steal your identity or logins? Sadly, the answer is often no.
Malicious browser extensions are the most underrated identity security threats to both individuals and enterprises. Just in the past six months, these malicious browsers have led to multiple breaches and vulnerabilities that exposed nearly ten million users worldwide to identity risks and data theft, and have even prompted the FBI to issue warnings against compromised extensions.
So, who can you trust? The answer is complicated because of the way extensions can be created, co-opted by bad actors and broadly re-shared. The problem, however, is that getting full information and assessing the risk of each extension is out of reach for most users.
Stores only do a superficial job of vetting extensions. They may do simple verifications to check for obvious red flags, but itโs not part of their workflow to investigate deeper indicators of suspicious or malicious behavior.
ExtensionPedia, a one-stop, comprehensive resource evaluating the security of more than 200,000 browser extensions, announced today by LayerX, exactly addresses this challenge. For the first time, individuals and businesses can easily access extension risk analyses to distinguish between safe, risky and malicious tools.
Offered online as a public service, individuals and enterprises can find detailed risk assessments and scores of extensions they are considering for Chrome, Edge and Firefox before they install them, and a knowledge center providing guidance on protecting against malicious browser extensions.
โWhile browser extensions are often considered harmless, in practice they are frequently granted extensive access permissions to usersโ identity information and data, leading hackers to use them as an attack channel for credential theft, account takeover and data theft,โ said Or Eshed, co-founder and CEO of LayerX.
โWhen someone installs a browser extension โ either for personal or work โ users and their organizations have no idea what permissions each extension has, how reputable the extension author is and the risk profile of the extension. Our Browser Extension Risk Database and Knowledge Center for the first time helps get the information individuals and enterprises to protect themselves,โ he said.
About the Browser Extension Risk Database and Knowledge Center
The new ExtensionPedia is extremely effective because it allows anyone to research any extension, view its risk assessment, and take measures to secure themselves against risky extensions. Assessments are based on anonymous data garnered from millions of sessions using the LayerX platform, a user-centric extension designed to protect identities directly in the browser, where most modern identity threats occur.
