Hash Fields

The hash fields represent different bitwise hash algorithms and their values.

Field names for common hashes (e.g. MD5, SHA1) are predefined. Add fields for other hashes by lowercasing the hash algorithm name and using underscore separators as appropriate (snake case, e.g. sha3_512).

Note that this fieldset is used for common hashes that may be computed over a range of generic bytes. Entity-specific hashes such as ja3 or imphash are placed in the fieldsets to which they relate (tls and pe, respectively).

Hash Field Details

edit

Field	Description	Level
hash.cdhash	[beta] This field is beta and subject to change. Code directory hash, utilized to uniquely identify and authenticate the integrity of the executable code. type: keyword example: `3783b4052fd474dbe30676b45c329e7a6d44acd9`	extended
hash.md5	MD5 hash. type: keyword	extended
hash.sha1	SHA1 hash. type: keyword	extended
hash.sha256	SHA256 hash. type: keyword	extended
hash.sha384	SHA384 hash. type: keyword	extended
hash.sha512	SHA512 hash. type: keyword	extended
hash.ssdeep	SSDEEP hash. type: keyword	extended
hash.tlsh	TLSH hash. type: keyword	extended

Field Reuse

edit

The hash fields are expected to be nested at:

dll.hash
email.attachments.file.hash
file.hash
process.hash

Note also that the hash fields are not expected to be used directly at the root of the events.
