Post follow-up: PC-to-Mobile Virus Found

Back in November, I wrote about the potential for malware jumping between computers and our increasingly-complex handheld devices. It appears that the first PC-to-mobile virus has been developed and submitted to MARA (Mobile Antivirus Researchers Association) as a proof-of-concept. The threat is no longer theoretical, it is now practical. While this particular threat attacks via Microsoft ActiveSync, users and developers alike should begin thinking about other attack vectors such as Bluetooth and begin exercising restraint when using these technologies, being mindful of the principle of least privilege.
