volatility3.plugins.linux.elfs module

A module containing a plugin for enumerating memory-mapped ELF files across all processes.

class Elfs(context, config_path, progress_callback=None)

Bases: PluginInterface

Lists all memory mapped ELF files for all processes.

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 elf_dump(context, layer_name, elf_table_name, vma, task, open_method)

Extracts an ELF as a FileHandlerInterface :type context: ContextInterface :param context: the context to operate upon :type layer_name: str :param layer_name: The name of the layer on which to operate :type elf_table_name: str :param elf_table_name: the name for the symbol table containing the symbols for ELF-files :type vma: ObjectInterface :param vma: virtual memory allocation of ELF :type task: ObjectInterface :param task: the task object whose memory should be output :type open_method: Type[FileHandlerInterface] :param open_method: class to provide context manager for opening the file

Return type:

Optional[FileHandlerInterface]

Returns:

An open FileHandlerInterface object containing the complete data for the task or None in the case of failure

classmethod get_requirements()

Returns a list of Requirement objects for this plugin.

Return type:

List[RequirementInterface]

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()

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 = (2, 0, 3)
