Is there a way to generate a SHA1 hash of all files on all our computers so we can compare them later?
I believe we could use the certutil -hashfile sha1 command on the computers and run it as an analysis…
Back at Think 2018 some guys from Stanford gave an interesting talk on a powershell script that they had created to gather information including hashes for file extensions they identified as being interesting. Maybe it could be useful for what you are trying to accomplish. I’ve linked to the original post and the repo for the script below.
Note that BigFix Inventory provides this capability as well: https://help.hcltechsw.com/bigfix/9.5/inventory/Inventory/security/t_checksums_main.html
