The official blog of Research in Motion was hacked today by Team Poison. The Canadian company had earlier promised to help British authorities track down BlackBerry users suspected of involvement in the local unrest. From AFP:

"If you do assist the police by giving them chat logs, GPS locations, customer information and access to peoples' BlackBerry Messengers, you will regret it," said the post.

The message went on to say a hacked database containing the names, addresses and phone numbers of RIM employees would be made public and "passed onto rioters" if RIM did not comply.

"Do you really want a bunch of angry youths on your employees doorsteps?" it warned. "Think about it."

RIM officials in Britain offered Monday to assist authorities "in any way possible."

I doubt this will be much help to anyone worried by RIM's presumed eagerness to hand over its secure messaging system for state inspection.

CNN reports that there are further demands to completely shut down the network.

Some London public officials have asked RIM to shut down BlackBerry Messenger temporarily to stem further unrest. A representative for RIM did not immediately respond to a request for comment.

What next? Facebook and Twitter?
