@redford@infosec.exchange and @mrtick@infosec.exchange held an unrecorded talk a bout this at OhMyHack in Warsaw - I unfortunately couldn't make it because of Munich snow. For now this is making the rounds in Polish-speaking sources, but we do have a talk scheduled about this at 37C3, in which we plan to do a deep dive into this and actually publish our findings. @zaufanatrzeciastrona@infosec.exchange 's article about this: https://zaufanatrzeciastrona.pl/post/o-trzech-takich-co-zhakowali-prawdziwy-pociag-a-nawet-30-pociagow/
