Nuclear Plants Leak Critical Alerts In Unencrypted Pager Messages (arstechnica.com)

mdsolar quotes a report from Ars Technica: A surprisingly large number of critical infrastructure participants -- including chemical manufacturers, nuclear and electric plants, defense contractors, building operators and chip makers -- rely on unsecured wireless pagers to automate their industrial control systems. According to a new report, this practice opens them to malicious hacks and espionage. Earlier this year, researchers from security firm Trend Micro collected more than 54 million pages over a four-month span using low-cost hardware. In some cases, the messages alerted recipients to unsafe conditions affecting mission-critical infrastructure as they were detected. A heating, venting, and air-conditioning system, for instance, used an e-mail-to-pager gateway to alert a hospital to a potentially dangerous level of sewage water. Meanwhile, a supervisory and control data acquisition system belonging to one of the world's biggest chemical companies sent a page containing a complete "stack dump" of one of its devices. Other unencrypted alerts sent by or to "several nuclear plants scattered among different states" included:

-Reduced pumping flow rate
-Water leak, steam leak, radiant coolant service leak, electrohydraulic control oil leak
-Fire accidents in an unrestricted area and in an administration building
-Loss of redundancy
-People requiring off-site medical attention
-A control rod losing its position indication due to a data fault
-Nuclear contamination without personal damage
Trend Micro researchers wrote in their report titled "Leaking Beeps: Unencrypted Pager Messages in Industrial Environments": "We were surprised to see unencrypted pages coming from industrial sectors like nuclear power plants, substations, power generation plants, chemical plants, defense contractors, semiconductor and commercial manufacturers, and HVAC. These unencrypted pager messages are a valuable source of passive intelligence, the gathering of information that is unintentionally leaked by networked or connected organizations. Taken together, threat actors can do heavy reconnaissance on targets by making sense of the acquired information through paging messages. Though we are not well-versed with the terms and information used in some of the sectors in our research, we were able to determine what the pages mean, including how attackers would make use of them in an elaborate targeted attack or how industry competitors would take advantage of such information. The power generation sector is overseen by regulating bodies like the North American Electric Reliability Corporation (NERC). The NERC can impose significant fines on companies that violate critical infrastructure protection requirements, such as ensuring that communications are encrypted. Other similar regulations also exist for the chemical manufacturing sector."

  23. Nuke shutdown by emil · · Score: 1

    We need nuclear power that can be shut down at a moment's notice, with no further intervention necessary by the operators.

    Gen 1 designs require 30 days of cooling post-shutdown before daughter nuclei decay stops producing massive heat.

    I am looking for a salt plug that melts and scrams the core in a boron bath.

    The TESCO employees were desperate for batteries for the cooling system, because they knew what was about to happen. I have the same reactor design 50 miles away. It's colossally dumb, and we need these things offline pronto.

      The Chernobyl Exclusion Zone is only 2,600 km^2, or less than half a percent of the area of a not-that-big country, and even it is full of thriving wildlife and tourists. Modern reactor designs would be desirable, but no commercial reactor is going to make a mess big enough to render a large portion of the country uninhabitable. FUD.

    Satellite pagers (and in more modern times, texts over the cellular network) are the most reliable way to get alarms out to field and on-call personal. Sure, someone could send a malicious fake page or text, but these alarms are mainly just heads-up to personal who are not in the operations center that something is amis. The main board will always be checked / personal will always call in and double check before anyone actually pushes any buttons.

    It's BS because you have no realistic threat model here and the only thing remotely sensitive is an allegation of a stack trace that is probably not meaningful and which would involve things to which they have no access anyhow. The pagers are simple alerts. They're not a two-way communication channel. Pagers don't "automate" anything--they can't control anything because there's no outbound communication. Which is basically the first line of the summary, so we know pretty much how much you (didn't) read.
