The US military's cybersecurity is extraordinarily weak

The Government Accountability Office released a new report on Tuesday that shows worrying cybersecurity flaws in U.S. weapons systems. Worse, the GAO report found that the Department of Defense knew about the vulnerabilities but didn’t take them seriously, leaving even systems still under development open to attack. For five years, until 2017, in-house DoD teams “routinely founds mission critical cyber vulnerabilities in nearly all weapons systems that were under development.” The tests used to assess security weren’t that complicated, but still found that key military systems could be taken control of by someone not authorized and operated largely undetected.
