US Advanced Weaponry Is Easy to Hack, Even by Low-Skilled Attackers October 9, 2018 https://www.bleepingcomputer.com/ne...s-easy-to-hack-even-by-low-skilled-attackers/ Report: "Weapon Systems Cybersecurity: DOD Just Beginning to Grapple with Scale of Vulnerabilities" (PDF): https://www.gao.gov/assets/700/694913.pdf
Take control - hardly. I refuse to believe DoD admins are so inept to allow glaring misconfigs. Well, that was until I read this, from the PDF - Disrupt - yes. There is no efficient defense against certain simple attack techniques. Just look at "Table 6: Examples of Types of Cyber Attacks" . But - that would really depend on where the given system is being scanned from. Testers could have had a very-near access (say from a LAN), but this is not specified. There is merit in what they say, but these articles tend to generalize things a bit too much which is to be expected as they do need their hits. (Again edited for typos.)
