A malicious Trojan horse program has emerged for Pocket PCs, antivirus companies said Thursday, but they characterized the threat as relatively low. The program, known alternately as Backdoor.Bardor.A and WinCE.Brador.a, lets an attacker gain full control of the handheld and is the first such "backdoor Trojan" program to emerge for Pocket PCs. However, such backdoor programs are not capable of propagating on their own and instead must be sent as e-mail attachments or through similar means, making them less dangerous. Symantec rated the bug a "1," the lowest on its five-point scale. In a statement, the company offered the standard warning not to open or execute files from unknown sources.
