this is the command im running
./chainsaw_x86_64-pc-windows-msvc.exe hunt -s sigma/ --mapping mappings/sigma-mft-logs-all.yml C:/Windows/System32/winevt/Logs --from 2023-11-18T17:00:00 --to 2023-11-19T01:45:00 --full
this is the output in getting in return
[+] Loading detection rules from: sigma/
[!] Loaded 3040 detection rules (339 not loaded)
[x] Provided mapping file is invalid - groups[0]: missing field filter
at line 8 column 5
i looked into the yml file and i see that theres a comment hinting at the possibility that this is a known issue i dont necessarily get it ? line 8 column 5 is just after the comment ## TODO: Flesh this out... but sigma does not seem geared for this?

Hey @gr3y56, which issue are you referring to? Are you able to explain what is not working? If so then I should be able to assist.

Right okay, so I never did the initial MFT work, but from looking over it the reason the mapping file is empty is because there is no easy way to map the sigma rules onto an MFT. They all appear to be very event log centric. I think what I will do is remove that mapping file as it just causes confusion, that being said you can still dump or search an MFT with the following commands or rules could be written to hunt MFTs.
chainsaw dump ~/Downloads/mft.bin
# or
chainsaw search -t 'FullPath: *Teams.exe' ~/Downloads/mft.bin
