Highway traffic systems deployed across the United States could be open exploit via what a group of researchers has deemed an “insufficient entropy vulnerability” in the systems’ software. Read More ..
According to an advisory (.PDF) issued late last week by the U.S. Industrial Control System Computer Emergency Readiness Team (ICS-CERT), systems built by the Houston, Tex. based company Post Oak Traffic Systems could allow unauthorized access. In particular, the company's traffic monitoring systems that rely on Anonymous Wireless Address Matching (AWAM) Bluetooth readers that appear to be in danger.
