2. Upgrade (upgrade) and Updates (update)
You can download updates for THOR with “thor-util.exe” (Windows) or “thor-util” (Linux, macOS).
Running “thor-util --help” shows three options that seem to have a very similar meaning: “upgrade”, “update” and “download”.
The difference is that the “download” option downloads a full pack with all config files while the “upgrade” option fetches a full package but excludes the config files to avoid accidental overwrites of local config files (like: thor.yml, falsepositive_filters.cfg etc.).
The “update” option retrieves only the newest signature pack (not the program files).
Get new program files and signatures
Get new signatures
Get new program files, signatures and config files
If you have a full program package present, you should use the “upgrade” option.
Every other option has its own help. You can see the help of each option with
thor-util *option* --help
The following two examples show different upgrade methods.
thor-util.exe upgrade thor-util.exe upgrade -a https://proxy.company.net:8080 thor-util.exe upgrade -a https://proxy.company.net:8080 -n dom\\user -p password thor-util.exe upgrade -a https://proxy.local:8080 --ntlm -n dom\\user -p password

2.3. SigDev Signatures
Usually it takes our internal testing 1-2 days to verify the quality of new rules. In rare cases in which a new and severe threat has been discovered it could make sense to use the newest and untested signatures that are still in our testing process. (e.g. new vulnerability and public proof-of-concept code)
To retrieve the newest and untested signatures you can use the
thor-util.exe update --sigdev flag.
To reset the signature set to the latest stable version use
thor-util.exe update --force. (retrieve the stable set and enforce the download even if the current set is newer)
