volatility3.framework.layers.vmware module

exception VmwareFormatException(layer_name, *args)[source]

Bases: LayerException

Thrown when an error occurs with the underlying VMware vmem file format.

add_note()

Exception.add_note(note) – add a note to the exception

args
with_traceback()

Exception.with_traceback(tb) – set self.__traceback__ to tb and return self.

class VmwareLayer(context, config_path, name, metadata=None)[source]

Bases: SegmentedLayer

Basic initializer that allows configurables to access their own config settings.

property address_mask: int

Returns a mask which encapsulates all the active bits of an address for this layer.

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.

property dependencies: List[str]

Returns a list of the lower layers that this layer is dependent upon.

destroy()

Causes a DataLayer to close any open handles, etc.

Systems that make use of Data Layers should call destroy when they are done with them. This will close all handles, and make the object unreadable (exceptions will be thrown using a DataLayer after destruction)

Return type:

None

classmethod get_requirements()[source]

This vmware translation layer always requires a separate metadata layer.

Return type:

List[RequirementInterface]

group_structure = '64sQQ'
header_structure = '<4sII'
is_valid(offset, length=1)

Returns whether the address offset can be translated to a valid address.

Return type:

bool

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

mapping(offset, length, ignore_errors=False)

Returns a sorted iterable of (offset, length, mapped_offset, mapped_length, layer) mappings.

Return type:

Iterable[Tuple[int, int, int, int, str]]

property maximum_address: int

Returns the maximum valid address of the space.

property metadata: Mapping

Returns a ReadOnly copy of the metadata published by this layer.

property minimum_address: int

Returns the minimum valid address of the space.

property name: str

Returns the layer name.

read(offset, length, pad=False)

Reads an offset for length bytes and returns ‘bytes’ (not ‘str’) of length size.

Return type:

bytes

scan(context, scanner, progress_callback=None, sections=None)

Scans a Translation layer by chunk.

Note: this will skip missing/unmappable chunks of memory

Parameters:
Return type:

Iterable[Any]

Returns:

The output iterable from the scanner object having been run against the layer

translate(offset, ignore_errors=False)
Return type:

Tuple[Optional[int], Optional[str]]

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]

write(offset, value)

Writes a value at offset, distributing the writing across any underlying mapping.

Return type:

None

class VmwareStacker[source]

Bases: StackerLayerInterface

exclusion_list: List[str] = []

The list operating systems/first-level plugin hierarchy that should exclude this stacker

classmethod stack(context, layer_name, progress_callback=None)[source]

Attempt to stack this based on the starting information.

Return type:

Optional[DataLayerInterface]

stack_order = 20

The order in which to attempt stacking, the lower the earlier

classmethod stacker_slow_warning()
