- _zagj 1y ago> No wonder they got into Natanz with stuxnet. While the PCs used to program the PLCs were running XP, the 0-day that Stuxnet exploited affected all versions of Windows, at least from 2000 onwards, including 2008 and Vista. EDIT: to clarify, the PCs "programmed" the PLCs indirectly, in that while they ran the Siemans STEP 7 IDE to design the centrifuges' control process, the resulting PLC programs were manually transported to the PLCs via USB devices, so there were two airgaps: the XP-running PCs airgapped from the outside world, and then another airgap between the PCs and the PLCs they programmed.
- dijit 1y agoThis massively trivialises how sophisticated stuxnet was, there were multiple 0-days affecting all versions of actively maintained versions of Windows being weaponised by the program. It wasn’t a bunch of known vulnerabilities affecting unpatched machines. Quite the opposite.
