RIM talks about security threat of DDOS attacks on carriers


Scott Totzke, RIM’s vice-president of BlackBerry security, recently spoke with the press about the potential of the DDOS attack by hackers using BlackBerry devices to target wireless networks. The thought is that because the BlackBerry is essentially a smaller PC, it could be used in a similar manner to overload networks.

But is this really a big concern? I have to agree with Ronen at BerryReview, that someone stealing personal data with an application seems like a bigger concern. All you have to do is build an application that accesses user data, and sends it back to the company’s servers. If they wanted to, a company could use the data on your BlackBerry for malicious purposes.

It seems like only a matter of time until someone in Nigeria figures out how to submit a malicious app into Mobihand. While App World might have a vetting process that looks at what the app is accessing, I can guarantee you the Mobihand network isn’t diligent enough to catch something like this.

Remember, Mobihand are the same people who sell NetworkACC, a bogus application that claims to speed up your mobile network. Not only is the app bogus and a waste of money, but I bet you eMobiStudio are gaming the review system because their app is filled with 5 star reviews. Mobihand have such a weak review system that anyone can write a hundred positive reviews about their app.

We can only hope that if a malicious app shows itself, the good people at BlackBerry Cool, BerryReview, CrackBerry, etc. will find out and spread the word not to download it.

B.C. criminals using BlackBerrys


CriminalAccording to a recent RCMP threat assessment report, BlackBerrys are helping organized crime get a bit more organized. The increasing affordability of the BlackBerry Enterprise Server and devices themselves is making BlackBerry a choice purchase for criminals in British Columbia. The enterprise-level security makes it difficult for law enforcement officials to crack information on the devices, as well as plant wiretaps.

“Every message that is sent via a BlackBerry is broken up into 2Kb [kilobyte] packets of information, each of which is given a 256-bit key by the BlackBerry server,” said [Scott Totzke, RIM’s vice-president of global security]. “That means to release the contents of a 10Kb e-mail, a person would have to crack five separate keys, and each one would take about as long as it would for the sun to burn out — billion of years.”

What do you guys think, are BlackBerry communications getting too secure for their own good?
