Such systems also most likely are not vulnerable to Meltdown/Spectre.
- vokep 8y agoWhy would you begin to think that at all? Because they're offline doesn't mean that they're safe, just safe from more than an online system.
- darpa_escapee 8y agoThose systems might be immune to attacks that networked machines are vulnerable to, but often networked attacks are used in order to leverage another exploit, such as Meltdown/Spectre. A vector other than the network could be exploited to leverage an attack that utilizes Meltdown/Spectre.
- fulafel 8y agoMost the biggest software vulnerability catastrophies actually involve just such systems. "Secure internal network" is a 90s mirage. See eg https://www.wired.com/story/notpetya-cyberattack-ukraine-russia-code-crashed-the-world/ https://www.wired.com/story/notpetya-cyberattack-ukraine-rus...
- dtech 8y agoMeltdown & co. only become relevant once you can execute on a CPU. If an adversary can run software on your industrial robot, you are already compromised.
- fulafel 8y agoThink browsers and virtualization, and the various VPN's that invariably connect "internal networks" to the outside world via computers that straddle, or alternate between, other networks.
