Look to the sky: How hackers could control cranes by abusing radio frequencies
Vulnerabilities in radio frequency protocols used by remote controllers could allow hackers to move cranes and other big machinery at construction sites and factories, security researchers said Tuesday, raising awareness of potential safety issues in widely-used technology. A research team at cybersecurity company Trend Micro examined remote controllers made by seven vendors and found that all of them were susceptible to “replay attacks,” in which an attacker transmits a recorded radio frequency (RF), tricking the machinery into responding to commands. In other words, the researchers said, the remote control you use to open your garage is probably more secure than many controllers used to move industrial equipment. The main problem, Trend Micro said in a paper published Tuesday, is that instead of relying on standard wireless technologies, the industrial remote controllers depend on proprietary RF protocols that are decades old and “are primarily focused on safety at the expense of […]
