A library catalog-PC malware event exposes several hash fields named file_hash, file_hash_md5, and file_hash_sha256. How can the analyst lowercase every file_hash* field in one pass for intel matching?
Select an answer to reveal the explanation.
Short Explanation
When a malware event shows up with a handful of hash fields, foreach file_hash* is the bulk stamp that lowercases every one of them. No need to name each hash by hand, and no need to pretend the data model already folded the case for you.
Full Explanation
foreach accepts wildcard field names, so file_hash* selects every hash field on the library malware event and applies the same eval. That is a security-analysis use: normalize indicators before an intel lookup. transaction groups events and does not lowercase fields. makeresults synthesizes rows rather than transforming the live malware event, and data-model acceleration does not case-fold hash values on its own.
