volatility3.plugins.linux.malware.process_spoofing module

class ProcessSpoofing(context, config_path, progress_callback=None)[source]

Bases: PluginInterface

Detects process spoofing by comparing executable path to cmdline & comm fields.

Examples of such behavior can be found here: https://github.com/SolitudePy/linux-mal

Parameters:

  • context (ContextInterface) – The context that the plugin will operate within

  • config_path (str) – The path to configuration data within the context configuration data

  • progress_callback (Optional[Callable[[float, str], None]]) – A callable that can provide feedback at progress points

build_configuration()

Constructs a HierarchicalDictionary of all the options required to build this component in the current context.

Ensures that if the class has been created, it can be recreated using the configuration built Inheriting classes must override this to ensure any dependent classes update their configurations too

Return type:

HierarchicalDict

property config: HierarchicalDict

The Hierarchical configuration Dictionary for this Configurable object.

property config_path: str

The configuration path on which this configurable lives.

property context: ContextInterface

The context object that this configurable belongs to/configuration is stored in.

classmethod extract_process_names(context, task)[source]

Extract all process name sources for comparison

Return type:

Tuple[Optional[str], Optional[str], Optional[str], Optional[str], bool]

Returns:

Tuple of (exe_path, exe_basename, cmdline_basename, comm)

classmethod get_cmdline_basename(context, task)[source]

Extract the command line arguments and return the basename of the first argument.

Notes

The read length is capped at MAX_ARG_STRLEN (32 * 4096) per the kernel limit defined in include/uapi/linux/binfmts.h (see linux.git commit f6031913338f1dad5bd8cb7286ff4e53644b6940).

Parameters:
Return type:

Optional[str]

Returns:

Basename of the first command line argument or None if not available

classmethod get_comm(task)[source]

Extract the comm field from task_struct

Parameters:

task (ObjectInterface) – task_struct object of the process

Return type:

Optional[str]

Returns:

Process name from comm field or None if not available

classmethod get_executable_path(context, task)[source]

Extract the executable path from task_struct.mm.exe_file

Parameters:
Return type:

Optional[str]

Returns:

Returns executable path or None if not available

classmethod get_requirements()[source]

Returns a list of Requirement objects for this plugin.

classmethod make_subconfig(context, base_config_path, **kwargs)

Convenience function to allow constructing a new randomly generated sub-configuration path, containing each element from kwargs.

Parameters:

  • context (ContextInterface) – The context in which to store the new configuration

  • base_config_path (str) – The base configuration path on which to build the new configuration

  • kwargs – Keyword arguments that are used to populate the new configuration path

Returns:

The newly generated full configuration path

Return type:

str

property open

Returns a context manager and thus can be called like open

run()[source]

Executes the functionality of the code.

Note

This method expects self.validate to have been called to ensure all necessary options have been provided

Returns:

A TreeGrid object that can then be passed to a Renderer.

set_open_method(handler)

Sets the file handler to be used by this plugin.

Return type:

None

classmethod unsatisfied(context, config_path)

Returns a list of the names of all unsatisfied requirements.

Since a satisfied set of requirements will return [], it can be used in tests as follows:

unmet = configurable.unsatisfied(context, config_path)
if unmet:
    raise RuntimeError("Unsatisfied requirements: {}".format(unmet)
Return type:

Dict[str, RequirementInterface]

version = (1, 1, 0)
