ioc-hunter 1.3.7

Extract IOCs from text.

ioc-hunter

IOC Hunter finds indicators of compromise (IOC). The parse_iocs function can extract IOCs from text.
The type_ioc function can determine the IOC type of a string that you pass in.

The IOCs that are recognized are:

• ssdeep
• sha256
• sha1
• md5
• email
• ipv4_public
• ipv4_private
• ipv6_public
• ipv6_private
• filename
• domain
• url

Parse IOCs

The parse_iocs function parses IOCs in the list above from text. There is an option to defang the IOCs that are passed back as well as an option to provide a whitelist regex. This will also return IOCs labeled as unknown when text is found to be suspicious, but doesn't match any of the IOC types.

from ioc_hunter import parse_iocs

text = "Your text goes here"
whitelist = r".*internaldomain\.com.*"
iocs = parse_iocs(text, defang=False, whitelist_regex=whitlist)

parse_iocs

Params:
    text – A string to parse.
    defang – If True, defang any IOCs we can (see DEFANGABLE). If False, return IOCs in their fanged state.
    whitelist_regex – Any IOC matching this regex will be ignored
    iocs_to_parse – A list of IOC types to look for (see IOC_TYPES_SEARCH_ORDER for options)
    whitelist_domains – A list or CSV of domains to exclude from results. Excludes domains and URLs that match
    whitelist_ip_cidr_ranges – A list or CSV of CIDR ranges to exclude from results. Excludes IPs and URLs that match
Returns:
    A dictionary with the ioc type as the key and a list of iocs for each value.

Type IOC

The type_ioc function takes in text and determines if that text matches any of the IOC types. If it does not match any, it will return unkown.

from ioc_hunter import type_ioc

suspected_ioc = "mydomain.com"
ioc_type = type_ioc(suspected_ioc)

type_ioc

Params:
    ioc – The IOC to classify.
    types_to_find – A list of types you want to look for.
Returns:
    The type of the IOC as a string, (see IOC_TYPES_SEARCH_ORDER for options)
