Attached: 1 image I can finally reveal some research I've been involved with over the past year or so. We (@redford@infosec.exchange, @mrtick@infosec.exchange and I) have reverse engineered the PLC code of NEWAG Impuls EMUs. These trains were locking up for arbitrary reasons after being serviced at third-party workshops. The manufacturer argued that this was because of malpractice by these workshops, and that they should be serviced by them instead of third parties. 1/4

A polish hacker found out why trains did stop working. The manufacterer implemented a hidden electronic switch, which automatically activated after trains were serviced by a different company.

    Somehow this is the worst bit – a Polish company fucks the Polish state railway operator because of greed. If they’d done this in another country, there might have been some international repercussions etc. but they opted to burn their name in their own home country. This being found by random hackers is actually the best way for Newag for this affair to become public. This could have been so much worse.
