One particularly dangerous aspect of extensions is how they can be updated automatically. But it does happen, and people should be aware that extensions aren't harmless. Of course, this isn't happening with the majority of extensions, and the companies that maintain web stores for them have been cracking down on malicious behavior. It could be secretly redirecting your search traffic to a different place or selling your internet browsing data to advertisers.
They're running when you check Facebook, when you transfer money from your bank's website, and when you enter your credit card information on Amazon.Ī malicious extension could easily be logging your keystrokes to steal passwords and personal information. On top of that, extensions are running in your browser all the time.
