Adversaries may interact with the Windows Registry to gather information about the system, configuration, and installed software.
The Registry contains a significant amount of information about the operating system, configuration, software, and security.  Some of the information may help adversaries to further their operation within a network.
|ADVSTORESHELL||ADVSTORESHELL can enumerate registry keys.  |
|APT32||APT32's backdoor can query the Windows Registry to gather system information. |
Azorult can check for installed software on the system under the Registry key
|BACKSPACE||BACKSPACE is capable of enumerating and making modifications to an infected system's Registry. |
|Bankshot||Bankshot searches for certain Registry keys to be configured before executing the payload. |
|Brave Prince||Brave Prince gathers information about the Registry. |
Carbanak checks the Registry key
|Carbon||Carbon enumerates values in the Registry. |
Cardinal RAT contains watchdog functionality that periodically ensures
|CHOPSTICK||CHOPSTICK provides access to the Windows Registry, which can be used to gather information. |
|Denis||Denis queries the Registry for keys and values. |
|Derusbi||Derusbi is capable of enumerating Registry keys and values. |
|DownPaper||DownPaper searches and reads the value of the Windows Update Registry Run key. |
|Dragonfly 2.0||Dragonfly 2.0 queried the Registry to identify victim information. |
Epic uses the
|FELIXROOT||FELIXROOT queries the Registry for specific keys for potential privilege escalation and proxy information. FELIXROOT has also used WMI to query the Windows Registry.  |
|FinFisher||FinFisher queries Registry values as part of its anti-sandbox checks.  |
Gold Dragon enumerates registry keys with the command
A variant of HOPLIGHT hooks lsass.exe, and lsass.exe then checks the Registry for the data value 'rdpproto' under the key
|Hydraq||Hydraq creates a backdoor through which remote attackers can retrieve system information, such as CPU speed, from Registry keys.  |
|InvisiMole||InvisiMole can enumerate Registry values, keys, and data. |
|JPIN||JPIN can enumerate Registry keys. |
Lazarus Group malware IndiaIndia checks Registry keys within HKCU and HKLM to determine if certain applications are present, including SecureCRT, Terminal Services, RealVNC, TightVNC, UltraVNC, Radmin, mRemote, TeamViewer, FileZilla, pcAnyware, and Remote Desktop. Another Lazarus Group malware sample checks for the presence of the following Registry key:
OilRig has used
|OSInfo||OSInfo queries the registry to look for information about Terminal Services. |
|PlugX||PlugX can enumerate and query for information contained within the Windows Registry.  |
|POWERSOURCE||POWERSOURCE queries Registry keys in preparation for setting Run keys to achieve persistence. |
|PowerSploit||PowerSploit contains a collection of Privesc-PowerUp modules that can query Registry keys for potential opportunities.  |
POWRUNER may query the Registry by running
Proxysvc gathers product names from the Registry key:
|QUADAGENT||QUADAGENT checks if a value exists within a Registry key in the HKCU hive whose name is the same as the scheduled task it has created. |
RATANKBA uses the command
|Reaver||Reaver queries the Registry to determine the correct Startup path to use for persistence. |
|Reg||Reg may be used to gather details from the Windows Registry of a local or remote system at the command-line interface. |
ROKRAT accesses the
|Shamoon||Shamoon queries several Registry keys to identify hard disk partitions to overwrite. |
|Stealth Falcon||Stealth Falcon malware attempts to determine the installed version of .NET by querying the Registry. |
|StoneDrill||StoneDrill has looked in the registry to find the default browser path. |
|SynAck||SynAck enumerates Registry keys associated with event logs. |
|Threat Group-3390||A Threat Group-3390 tool can read and decrypt stored Registry values. |
Turla surveys a system upon check-in to discover information in the Windows Registry with the
|Ursnif||Ursnif has used Reg to query the Registry for installed programs.  |
|Volgmer||Volgmer checks the system for certain Registry keys. |
|WINDSHIELD||WINDSHIELD can gather Registry values. |
Zebrocy executes the
|Zeus Panda||Zeus Panda checks for the existence of a Registry key and if it contains certain values. |
This type of attack technique cannot be easily mitigated with preventive controls since it is based on the abuse of system features.
System and network discovery techniques normally occur throughout an operation as an adversary learns the environment. Data and events should not be viewed in isolation, but as part of a chain of behavior that could lead to other activities, such as Lateral Movement, based on the information obtained.
Interaction with the Windows Registry may come from the command line using utilities such as Reg or through running malware that may interact with the Registry through an API. Command-line invocation of utilities used to query the Registry may be detected through process and command-line monitoring. Remote access tools with built-in features may interact directly with the Windows API to gather information. Information may also be acquired through Windows system management tools such as Windows Management Instrumentation and PowerShell.
