The attack on Blackberry Enterprise Server was reported after the hacking attempts on BlackBerry blog, which went offline on Tuesday, Aug 9. According to RIM, hackers used a "rigged image" to infiltrate Blackberry Enterprise Server and they may succeed to take control of BlackBerry devices connected to this server.
"An attacker would need to create a specially crafted Web page and then persuade the BlackBerry Smartphone user to click a link to that Web page. The attacker could provide the link to the user in an email or instant message," BlackBerry said in a statement.
Later the BlackBerry, which allows users to send encrypted emails, issued a patch for the vulnerability.
During the recent London riots, BlackBerry smartphones and social networking sites like Facebook and Twitter came under serious criticism over its alleged role in spreading the riot. The rioters used BlackBerry smartphones to send encrypted mails to others to organize protest against police.
BlackBerry blog was attacked by a hacker group called TeaMp0isoN. Hackers said that RIM can not allow police to catch the rioters.
"Dear Rim; You Will _NOT_ assist the UK Police because if u do innocent members of the public who were at the wrong place at the wrong time and owned a blackberry will get charged for no reason at all," hackers said in a message posted on BlackBerry blog.
