FBI Investigating Series of Fiber Cuts In San Francisco Bay Area 168

Posted by samzenpus from the cutting-the-line dept.
jfruh writes: Ten times over four separate nights in the past year, telecom cables have been mysteriously cut in various locations around the San Francisco Bay Area. Now the FBI is investigating the incidents as potential sabotage. ITWorld reports: "In the past year, there were 10 instances on four separate nights when telecom cables were intentionally cut in Fremont, Walnut Creek, Alamo, Berkeley and San Jose, the agency said Monday. FBI Special Agent Greg Wuthrich said it's unclear if the incidents are unrelated or the work of a single person or group, but the FBI is keen to hear from anyone who may have witnessed anything suspicious."

      Infrastructure is incredibly vulnerable.

      Some big problems:

      1. It is distributed all over the place, often just hanging on poles or with little protection beyond a fence.
      2. Cost-efficiency often results in minimal redundancy.
      3. Cost-efficiency often results in minimal inventory of spares and capacity to make repairs.

      Take out a couple of big transformers with a rifle and you could cut power over a very large area with a very lengthy repair time. Take out a fair number of them and you'll exhaust the supply of spares and now you could be talking months of problems (perhaps cannibalizing from other sites at reduced capacity across the grid, and if you take out enough you might just have to leave large areas blacked/browned-out).

      Fiber is also difficult to repair. If you had a determined attack you could probably rapidly outpace the ability to locate and repair cuts.

      Of course any kind of serious or sustained attack would draw attention and you'd find security improved. However, you could probably do a lot of damage before that happened.

      I think the best solution is to build more redundancy into infrastructure, and more capacity for repair. That also makes infrastructure more robust against other kinds of failure. It does cost money, and when you have privatization it requires some kind of way to pay those costs. The government could just buy capacity that it can make available in the event of a disaster. Of course, that would need to be real capacity, and not something that just gets oversubscribed (government buys 1GW of power but doesn't use it, utility just under-provisions by 1GW and sends the government the bill).

          I call bullshit.

          Transformer cooling oil isn't just cooling liquid. It's non-conductive, because the inside of a transformer is full of bare copper, all of which is energized when the transformer is in use. If you shoot a transformer, it doesn't just drain out...it's a whole lot worse than that. When a transformer develops an air gap, you get an arc inside the transformer, which ignites the oil in the event that sufficient pressure cannot build to cause a BLEVE, but causes a BLEVE...even if there's a hole in it, sometimes, based on where and how big the whole is...if the pressure is enough. It takes fractions of a second for this to happen, because you can have a massive flash of heat and concordant pressure spike. Things like this have been responsible for loss of life at substations. And it's not something you just fix like a hole in a radiator...you have to replace the whole transformer, and often a good part of the lines leading up to them as well. In the meanwhile, you end up with a sabotage report and law enforcement involvement, and reporting to the local PSC/PUC.

          Transformers detonate. They do it because the oil loses its dielectric property, or because an air space forms inside the transformer. The idea that linemen, who eventually would have seen an event like this take place as well as the injury/death that resulted (it's not all that rare, and used to be even more common, "back in the day") would cause such events just to get some overtime, sounds preposterous to me. It'd be like cops getting themselves shot at so that they could do the extra paperwork and get overtime, especially ones who had seen a colleague killed in the line of duty. I work in the power industry, today, and I've never heard of anything like this, nor have I met anyone who I believe would do this.

              But the poster isn't just speaking about a couple of psychopaths. He's describing a situation where people do this, do it often, and do it openly. Without even fear of consequences. And that nothing happened to them, when lots of people knew about it. And even more to the point, that this was a widespread thing.

              I say again: bullshit.

      • If you want to do it properly, make cuts in the fiber and multiple breaks or blocks in the conduits. It's one thing to repair a break, another to pull a new section of fiber, but if you have to dig up and replace conduits the job just got a whole lot bigger. Do it out in the bush and you disconnect whole cities or states.

      Not removing - adding.

      They'll break a fibre in two places - one 'obvious' and the other not so much. It depends what detection the owner can do as to where 'obvious' might be. While the owner is detecting the problem, isolating where it is on the fibre and sending out crews to fix it, the tap is applied in the second location, along with suitable repairs and whatnot.

      When the 'obvious' break is repaired, the owner just sees the light going down the fibre once again - they're not aware there's a tap. Indeed, if the tap consumes a little bit of light, forcing a recalibration at either end, it'll be attributed to the repair made at the 'obvious' break, and not the addition of the tap.

      Sadly, I'm pretty sure we'll never know which one of us is right about this particular point though.

        While the owner is detecting the problem, isolating where it is on the fibre and sending out crews to fix it, the tap is applied in the second location, along with suitable repairs and whatnot.

        I'd say that finding out where it is on the fiber is done by measuring the time it takes for a light pulse to reflect off the disturbance and converting that to distance. If the distances measured from both ends of the fiber do not add up to the length of the fiber, the owner of the fiber should get very suspicious. Would the eavesdropper take that risk?

        According to a friend of mine who's into fiber optics, tapping a fiber can be done without interrupting the fiber. If you bend a single-mode fiber, it will leak light, which is relatively easy to capture. The resulting signal loss of a few dB is likely to go unnoticed.

        • What you are describing is called an OTDR. Optical Time Domain Reflector IIRC.

          There is not much risk if you know what you are doing since the OTDR is only used at the most "convenient" end rather than both ends. Just make your secondary cut further away from where the repair crews will do the initial measuring.
