Well at the time of writing, No-IP.com’s services have been severely compromised meaning that DNS lookups for www.polaris64.net will always fail. So why don’t No-IP fix this problem? Well, it’s not their fault, it is Microsoft’s fault… Before I talk about what Microsoft has to do with this, for those of you who are not familiar with dynamic DNS services let me explain what No-IP is and why I and so many people use it. https://blog.polaris64.net/post/scadas-scarce-security/ Tue, 22 Nov 2011 00:00:00 +0000 https://blog.polaris64.net/post/scadas-scarce-security/ Yesterday, BBC news reported that a “hacker” had allegedly destroyed a pump in the Illinois water treatment system. Apparently, this person had managed to gain access to the system and break the pump by repeatedly turning it off and on. This attack on a SCADA system (Supervisory Control and Data Acquisition) follows a similar attack earlier this year by the Stuxnet virus which appeared to target the Siemens SCADA system of the Uranium nuclear enrichment facilities in Iran.
