From what I recall SCADA based monitoring and control systems were installed at many water / sewer processing, gas and oil

It is ridiculous to accept that a lightning strike could knock out the grid, or the transmission system is over stressed. There are many redundant fault, limit and Voltage-Surge Protection safeguards and related instrumentation and switchgear installed at the distribution centers and sub stations along the Power Grid that would have tripped to prevent or otherwise divert such a major outage. I believe that the outage was caused by the MSblaster, or its mutation, which was besieged upon the respective vulnerability in certain control and monitoring systems (SCADA and otherwise) running MS 2000 or XP, located different points along the Grid. Some of these systems are accessible via the Internet, while others are accessible by POTS dialup, or private Frame relay and dedicated connectivity. Being an old PLC automation and control hack let me say that there is a very good plausibility that the recent East Coast power outage was due to an attack by an MBlaster variant on the SCADA system at the power plant master terminal, or more likely at several of the remote terminal units "RTU". SCADA runs under Win2000 / XP and the telemetry to the RTU is accessible via the Internet. processing, and hydro-electric plants. I also believe that yesterdays flooding of a generator sub- facility in Philadelphia was also due to an MBlaster variant attack on the SCADA or similarly Win 2000 / XP based system. To make things worst, the Web Interface is MS ActiveX. Now lets see, how can one craft an ActiveX vuln vector into the blaster? Oh, and for the wardrivers, SCADA can be access via wireless connections on the road puts a new perspective on sniffing around sewer plants. It is also reasonable to assume that we could have a similar security threat regarding those system (SCADA and otherwise based on MS 2000 or XP) involved in the control, data acquisition, and maintenance of other critical infrastructure, such as inter/intra state GAS Distribution, Nuclear Plant Monitoring, Water and Sewer Processing, and city Traffic Control. IMO I think we will see a lot of finger pointing by government agencies, Utilities, and politicians for the Grid outage, until someone confess to the security dilemma and vulnerabilities in the systems which are involved in running this critical infrastructure. Regardless of whether the Grid outage can be attributed to the blaster or its variant, this is not entirely a Microsoft problem, as it reeks of poor System Security Engineering practiced by the Utility Companies, and associated equipment and technology suppliers. Nonetheless, the incident will cause lots of money to be earmarked by the US and Canadian Governments, to be spent in an attempt to solve the problem, or more specifically calm the public. This incident should be fully investigated, and regulations passed to ensure that the Utility companies and their suppliers develop and implement proper safeguards that will help prevent or at least significantly mitigate the effects of such a catastrophe. Conversely, I do not want to see our Government directly involved in yet another "business", which has such a controlling impact over our individual lives. - On 14 Aug 2003 at 15:18, Geoff Shively wrote:

Just flipped on CNN, watching the masses snake through the streets of Manhattan as correspondents state that this could be an affect of the blaster worm.

Interesting but I don't see how an worm of this magnitude (smaller than that of Slammer/Sapphire and others) could influence DCS and SCADA systems around the US, particularly just in the North East.

Thoughts?
