search events from txt

[cyberfan]

I have one txt file, only one column, the txt file has around 60 SHA-256 hashes. these hashes are from malicious files. I want to search the system any hosts associated with these hashes, what would be the search string I need to pass to splunk? thanks

You have a lookup file with hash values, but does Splunk have corresponding hash values in its indexes? Without both data there can be no search.
