I can finally reveal some research I've been involved with over the past year or so.

We (@redford, @mrtick 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.

Ups forgot about this one:)
Since everyone is flexing with their #flareon10 chal13 deobfuscators - here is my https://lokalhost.pl/dump/f2023_13_deob.py - pipe it to nasm and you’ll have a nice new binary ready to be analyzed ;)
