Google Gadget lovers were dealt a blow on Wednesday when two researchers outlined what they called a “hole” during a Black Hat presentation.
“The attacker can forcibly install Google Gadgets; they can read the victim’s search history once a malicious gadget has been installed in some specific circumstances; they can attack other Google Gadgets; they can phish usernames and passwords from victims, and so on,” said Robert Hansen, also known as RSnake, a founder of security consultancy SecTheory. “Really, the sky is the limit, once the browser is under the control of an attacker. And that point is exacerbated by the fact that people trust Google be a trustworthy domain, making the attacks even easier.”
Tom Stracener, a senior security analyst at Cenzic and co-presenter of the talk, outlined the threat:
Gadgets can attack other Gadgets: The potential impact of these attacks is through cookie theft, or theft of confidential and sensitive information from the Gadget or user.
Gadgets can attack the user: The type of attacks range from phishing to cross-site request forgery (when a user follows a link or clicks a form and unwittingly takes an action on a third party website that they did not intend to take).
Auto-adding a Gadget: A malicious webpage can add a Gadget to a user’s iGoogle homepage without his knowledge and assist in the spread of gadget-based malware.
Logging into an alternate Google account: A Gadget can log a user into a different Google account and monitor search queries.
“While the business impact from Google Gadget malware is minimal at this time,” Stracener says, “As the use of Google Gadgets moves from consumer to business use, the risks for business users will grow.”
