Viruses leap to smart radio tags (RFID)

Computer viruses could be about to take a giant leap and start spreading via smart barcodes, warn experts.

Security researchers have infected a Radio Frequency ID tag with a computer virus to show how the technology is vulnerable to malicious hackers.

The researchers warn that RFID tags could help mount many different types of attacks on computer systems.

Makers of radio tag systems were urged by the group to introduce safeguards to guard against RFID-borne bugs.

"This is intended as a wake-up call," said Andrew Tanenbaum, one of the researchers in the computer science department at Amsterdam's Free University that did the work revealing the weaknesses on smart tags.

"We ask the RFID industry to design systems that are secure," he said.
