It's not just desktop web browsers getting hacked at this year's Pwn2Own challenge -- mobile browsers have also been targeted for vulnerabilities, and a fairly big one has now been found in RIM's browser for BlackBerry OS 6. Apparently, there's a JavaScript-related bug that could let a "maliciously designed" website gain access to data stored on both the phone's media card and built-in storage, but not data stored in the storage portion for applications (such as email or contact information). For its part, RIM says that it hasn't actually seen any evidence of anyone exploiting the vulnerability, but it's nonetheless urging folks to disable JavaScript on affected devices, and it's now busy providing IT departments everywhere with guidelines on how to do so. If that proves to be complicated, it's suggesting that you simply disable the BlackBerry Browser altogether until it can be patched.
