Beware the Browser: Polymorphic Extensions Wreak Havoc on Security
Beware the sinister shapeshifting browser extensions! SquareX reveals that these crafty “polymorphic extensions” can impersonate any browser extension, including password managers and crypto wallets. They convincingly mimic icons and interfaces to trick you into handing over sensitive info. Who knew your browser toolbar could double as a costume party for malware?

Hot Take:
Move over catfishing, there’s a new impersonation game in town, and it’s got nothing to do with dodgy Tinder profiles. Browser extensions are now playing dress-up, and they’re not even asking for permission.
Key Points:
- SquareX discovers polymorphic extensions that mimic legitimate browser extensions.
- These extensions can impersonate password managers and crypto wallets, among others.
- The attack impacts major browsers like Chrome and Edge.
- The mimicry is so good, it’s like these extensions have a degree in method acting.
- SquareX suggests a need for advanced browser-native security solutions.
