quark.utils.tools module

quark.utils.tools.contains(subset_to_check, target_list)

Check the sequence pattern within two list.

subset_to_check = [“getCellLocation”, “sendTextMessage”] target_list = [“put”, “getCellLocation”, “query”, “sendTextMessage”] then it will return true. —————————————————————– subset_to_check = [“getCellLocation”, “sendTextMessage”] target_list = [“sendTextMessage”, “put”, “getCellLocation”, “query”] then it will return False.

quark.utils.tools.descriptor_to_androguard_format(descriptor)
quark.utils.tools.filter_api_by_usage_count(data, api_pool, percentile_rank=0.2)

Sorting APIs by the number of APIs used in APK, and split APIs into P_set (less used number) and S_set (more used number) by percentile_rank (default 20%).

Parameters:

  • data – the object of apkinfo.

  • api_pool – the APIs list for rule generation.

  • percentile_rank – the int for rank of percentile.

Return P_set:

a set of APIs that less used.

Return S_set:

a set of APIs that more used.

Get arguments from an argument string.

Parameters:

  • argument_str – string that holds multiple arguments and uses commas as separators

  • descriptor – string that holds a descriptor for type inference

Returns:

python list that holds the arguments

quark.utils.tools.get_parenthetic_contents(string: str, start_index: int) → str

Get the content between a pair of parentheses.

Parameters:

  • string – string to be parsed

  • start_index – index to specify the parenthesis

Returns:

string holding the content

quark.utils.tools.remove_dup_list(element)

Remove the duplicate elements in given list.
