Security researchers have warned that vulnerabilities in federal prison control systems could allow hackers to open prison doors remotely.

"The vulnerabilities – which stem from flaws in industrial control systems and programmable logic controllers – were demonstrated by a team led by John Strauchs, who demonstrated the flaws at the recent Hacker Halted information security conference in Miami," writes The Register's John Leyden.

"Possible exploits include overloading the electrical system that controls prison doors, locking them permanently open, or crashing either CCTV or prison intercom systems," Leyden writes.
