How do you automatically scan for malware in AES-256 encrypted files?
I am asking because Deutsche Post is offering something they call "E-PostBrief", which is seemingly encrypted but features a mandatory man-in-the-middle attack which is called 'malware scanner'. It's a joke honestly.
- andrewcooke 13y agohow do scanners normally work? i would have thought simple ones check hashes. if so, it's no different...
- rgbrenner 13y agoIf the files are encrypted w/ aes, there's no scanner that could detect a virus in the file. Every file would be different depending on the AES key used to encrypt it. The only way you're going to scan aes encrypted files is before they are encrypted.
- andrewcooke 13y agough - that was stupid of me. sorry you're completely right.
- jsnell 13y agoThe obvious solution would be to scan client-side.
