Nokia has posted on its website a page where the company informs users that it is following the laboratory test attempts to hack Bluetooth and is aware of consumer concerns about security issues related to malicious attempts by hackers to access mobile devices. Nokia recognises the Nokia 6310, 6310i, 6650, 8910 and 8910i mobile phones, the Nokia 610 car kit phone, and the Nokia 810 car phone as vulnerable to different forms of attacks, including Denial of Service attacks (DoS).
The company has outlined a schedule for the release of updated firmware for current devices in the market, as follows:
Nokia 6310: Beginning the week of September 20
Nokia 6310i: Beginning the week of September 13
Nokia 8910: Beginning the week of September 20
Nokia 8910i: Available now
Nokia 6650: Available now
Nokia 610: Beginning the week of October 18
Nokia 810: Beginning the week of October 18
To get an upgrade, owners of the above mentioned phone models may contact the Nokia Customer Care Line in your home country or an authorized Nokia Service Point.
Nokia says that it is not aware of any Bluetooth security attacks except for those made in the laboratory or for demonstration purposes. As part of active measures to protect devices, users are advised to set the mobile device to "hidden" mode. Personal devices like headsets can still connect to the phone, but intrusion is much more difficult since the hacker will have to know the Bluetooth address before establishing a connection.
There's also a Denial-of-Service (DoS) attack, currently only performed in laboratory tests against Bluetooth enabled devices. According to Nokia, there is no security threat as a result of DoS attacks. Even if a DoS attack is successful, there is no harm to the device, which will simply reboots itself, and is fully functional again.
