... This is a thing?
- unleaded 1y agodon't know about file roller but you can do this in 7-zip to peek at self-extracting archives
- creshal 1y agoFile roller does use 7z internally, so no real surprise here. But both implementations can be vulnerable to malicious exe files, so it's not a great idea to do this with a file you already suspect to be malicious.
- zahlman 1y agoAh. Those work by having a valid zip at the end (and extraction code in front), taking advantage of the zip format allowing for arbitrary data before the actual zip data (which in turn was intended to facilitate this sort of thing). It hadn't occurred to me that the .exe in question would be a self-extracting archive (or malicious code that also involves self-extracting an archive as part of the malicious working).
