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.
