Following the recent ‘cyber-jacking’ of the San Francisco Municipal Transportation Agency (Muni), Alex Cowan, the CEO of transport cyber defence experts Razor Secure, has warned rail, aviation and car manufacturers and operators that many more attacks on their distributed IT assets and networks will happen in the coming new year. The Muni hackers were able to use crypto-locker software to disable parts of their infrastructure, leaving the company unable to charge passengers for their journeys. But the financial costs may not stop there as the hackers also demanded a ransom to release the systems back to the company. It’s unclear how the hackers accessed the Muni network but the unlikely access points will become more relevant as more devices become connected and the Internet of Things expands. The proliferation of access points to ever bigger networks presents a huge challenge for those tasked with protecting our transport grids.
