Tepco’s corporate group company to operate 40% of Japanese nuclear plants got hacked / 3 days to identify malware

2 of the corporate group companies of Tepco had unauthorized computer access, Tepco announced on 10/10/2014. They state the head office of Tepco itself was not hacked.

One of those hacked companies is in charge of developing, maintaining and operating the systems to control 13 nuclear plants of Tepco, which is 40% of all the BWRs in Japan.

It was 10/7 to 10/8/2014 when they detected the unauthorized access to 13 computers but they couldn’t identify malware until 10/10/2014.

They haven’t checked if it caused any information leakage yet.

2 sociétés du groupe Tepco qui gèrent 40% des centrales nucléaires japonaise sont hackées / 3 jours pour identifier le malware


Tepco déclare ce 10 octobre 2014 que 2 sociétés du groupe Tepco ont été victimes d’accès non autorisés. Ils affirment que le quartier général de Tepco lui-même n’a pas été hacké.

Une des compagnies hackées est en charge du développement, de la maintenance et de l’exploitation des systèmes qui contrôlent 13 centrales nucléaires de Tepco, soit 40% de tous les réacteurs à eau bouillante (BWR) du Japon.
Les accès non-autorisés ont été détectés les 7 et 8 octobre 2014 sur 13 ordinateurs mais ils n’ont pas pu identifier le malware avant le 10 octobre 2014.
Ils n’ont pas encore vérifié s’il y a eu des fuites d’information.

  1. Friends don’t let friends run XP for internet access.

    Quote: “Monster banking Trojan botnet claims 500,000 victims “XP clients comprised 52 per cent of the infected systems””

    Let us not forget that both Target, Home Depot & Dairy Queen (et al?) ran POS2009 or similar, which are XP-SP3 derrivatives, for their cash registers. Of course poor procedure didn’t help their vulnerability profile, yet they do help show a growing trend relating to the use of these operating systems in a commercial environment.

    For TEmPCO to use this OS until 2019, one might think modifying their XP installs to be seen as POS2009 could have unintended side-effects. It is a simple one-line Windows Registry tweak.

    Am thinking it is OK to use XP isolated from the internet.
    That should only leave onsite security as the biggest vulnerability, if i have that correct.

    Real life should emulate art when XP and the internet are considered together, in my humble opinion. Sure, network them together, but isolate these networks entirely from the internet.

      1. Wired networks only, i should caution to those that live in apartments, condos, townhouses and the like. Connectivity should be via wired networks only to leave site security the major caveat, imho. The more densly populated an area the reader abides, the less they should consider using Bluetooth, and prolly never unencrypted (imho).

        You can get impedence-matching coaxial cable to wire a “Wireless” a/b/g/n/ac Adapter, by the way. Adapters are available for various WiFi connections, except for notebooks/tablets, of course. Ensure you are able to turn down the Transmit power on both sides of the connection before trying it out, if i have that right.

        One way to limit range on a WiFi router is to use the wall-wart that came with whatever router you use, it would seem. 🙂 Also, the connector used within seems to always be the same rivited center pin terminal that is notorious for poor conductivity and usual thermal degradation over time (one solder job away from fully conductive), but i digress. After all, there are no user-servicable parts (not a user? it’s at your own risk. Stay safe.). I usually go with a 3rd-party adapter that is capable of about double the current of the original, and the exact same DC voltage for stable power supply. Pocket AM radio helpf to find the crappy power bricks (et al), while under load.

        Charlie Demarjian has some interesting things to say about current tech, FWIW.

        I really liked his last paragraph. How about you, The Reader?
        It would be nice to hear somebody else’s point of view.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
