minus-squareboredsquirrellinkfedilink20•8 months agoI HIGHLY doubt that they would detect the XZ backdoor
minus-squarePossibly linuxlinkfedilinkEnglish4•edit-28 months agoEven if it did, what would you do? rm -rf /? XZ is part of the core system
minus-square@[email protected]linkfedilinkEnglish3•8 months agoWhy? It’s not hard. They typically hash files and look for hits against a database of known vulnerabilities.
minus-squareboredsquirrellinkfedilink7•8 months agoYes and if viruses use something like base64 encoding or other methods, the hashes dont match anymore. As far as I understood it, it is pretty easy to make your virus permanently un-hashable by just always changing some bits
minus-square@[email protected]linkfedilinkEnglish2•8 months agoThe xz backdoor was a packaged file distributed with the standard packages though. It would be trivial to find.
minus-squareboredsquirrellinkfedilink1•8 months agoThis is obviously not about this known file. It is about “would this scanner detect a system package from the official repos opening an ssh connection”

Oh well in that case there is no chance
