The Bluetooth functionality in Flamer is encoded in a module called "BeetleJuice". This module is triggered according to configuration values set by the attacker. This means that a computer compromised by W32.Flamer will appear when any other Bluetooth device scans the local area. In addition to enabling a Bluetooth beacon, Flamer encodes details about the infected computer (see Figure 1) and then stores these details in a special 'description' field. When any other device scans for Bluetooth-enabled devices, this description field will be displayed: These are the facts of how Flamer uses Bluetooth. The attacker, however, could identify the location of compromised devices using Bluetooth. The Beetlejuice module already has retrieved a list of all the devices IDs which are near to the infected computer and so the attacker knows what devices belong to the victim. Some attacks have even identified Bluetooth devices more than one mile away. With increase functionality an attacker, having identified various Bluetooth devices in range, could perform numerous attacks: - Steal contacts from an address book, steals SMS messages, steals images, and more. An attacker within one mile of the target could use their own Bluetooth-enabled device for this. If the second computer is using a secured network and was infected through a USB connection, potentially the only network available would be a Bluetooth connection back to the first compromised computer
