SAN FRANCISCO — A security researcher found that RuggedCom, a company that makes equipment and software for critical industrial control systems, planted a backdoor login account in its flagship operating system that potentially would allow hackers to access the devices online, reported.

According to independent researcher Justin W. Clarke, the backdoor is found in all versions of the Rugged Operating System and cannot be disabled.

Clarke said he discovered the backdoor after purchasing two used RuggedCom devices and examining the firmware installed on them.

RuggedCom, which is based in Canada, was recently purchased by Siemens.
