Russian forensics software maker Elcomsoft says it has developed the ability to crack passwords used to protect Blackberry phones. Failing to enter the password correctly more than 10 times in a row causes the data on the phone to be wiped clear. The password can be recovered directly from the removable media card in cases where the user has opted to encrypt that data also. The tool can circumvent the 10 wrong password limit, trying millions of password combinations per second to break the code a so-called brute force attack.
