I'm not familiar with these formats, but I can see that the patterns don't (really) work. Too many false positives. None of the lines starting with ">" do anything. For example, for the first pattern, I think what you're trying to do is this: 0 byte 66 >1 byte 171 >>2 byte 56 >>>3 byte 7 >>>>4 byte 190 >>>>>5 byte 131 >>>>>>6 byte 112 >>>>>>>7 byte 161 Proxmox Backup Server unencrypted uncompressed blob Or you could do the same thing in one line: 0 string \x42\xab\x38\x07\xbe\x83\x70\xa1 Proxmox Backup Server unencrypted uncompressed blob If you're able to run Python scripts, I humbly suggest that my Mgchkj utility can be helpful when writing new patterns. https://github.com/jsummers/mgchkj |

damn, indeed you are right , don't know anymore where i did get that syntax example from, maybe AI search was playing a prank on me and testing was just sucessful, because all files start with an inividual/different bytecode will send a fixed version. |
