Protecting Web Browsers from Security Abuse


Brian Krebs of KrebsOnSecurity provides information on why it’s a good idea to limit the number of extensions added to a web browser – they can increase the possibility of intrusion by hackers.

“Last week, KrebsOnSecurity reported to health insurance provider Blue Shield of California that its web site was flagged by multiple security products as serving malicious content. Blue Shield quickly removed the unauthorized code. An investigation determined it was injected by a browser extension installed on the computer of a Blue Shield employee who’d edited the web site in the past month.

“The incident is a reminder that browser extensions — however useful or fun they may seem when you install them — typically have a great deal of power and can effectively read and/or write all data in your browsing sessions. And as we’ll see, it’s not uncommon for extension makers to sell or lease their user base to shady advertising firms, or in some cases abandon them to outright cybercriminals.”

A web browser is like your own personal library. Keep it as secure as possible.
