Android Security Flaw Could Affect 99 Percent of Their Phones

Gives hackers a "master key" into the system

Security researchers believe they have found a major security flaw in the Google's Android mobile operating system, which could affect up to 99 percent of Android phones now in consumers' hands.

In results published Wednesday by the Bluebox Security research firm, chief technology officer Jeff Forristal said the flaw gave hackers a "master key" into the Android system.

Google declined to comment on the report.
