Xinglocker

MITRE ATT&CK does not currently catalogue Xinglocker, so this is our assessment of the techniques it uses, drawn from public reporting. The techniques themselves, and every "what that means" definition below, come from MITRE ATT&CK v19.2. Confidence: medium. Treat it as orientation, not attribution.

1. T1059.001 PowerShell Execution

   What they do: xinglocker uses PowerShell scripts to execute malicious commands and spread payloads across compromised systems.

   What that means: Adversaries may abuse PowerShell commands and scripts for execution.

2. T1106 Native API Execution

   What they do: xinglocker leverages native API calls to interact with system functions for execution and evasion.

   What that means: Adversaries may interact with the native OS application programming interface (API) to execute behaviors.

3. T1112 Modify Registry PersistenceDefense Impairment

   What they do: xinglocker modifies registry keys to establish persistence and alter system startup behavior.

   What that means: Adversaries may interact with the Windows Registry as part of a variety of other techniques to aid in defense evasion, persistence, and execution.

4. T1547.001 Registry Run Keys / Startup Folder PersistencePrivilege Escalation

   What they do: xinglocker uses registry run keys and startup folders to ensure recurring execution after reboots.

   What that means: Adversaries may achieve persistence by adding a program to a startup folder or referencing it with a Registry run key.

5. T1685 Disable or Modify Tools Defense Impairment

   What they do: xinglocker disables security tools like antivirus software to hinder incident response and persistence.

   What that means: Adversaries may disable, degrade, or tamper with security tools or applications (e.g., endpoint detection and response (EDR) tools, intrusion detection systems (IDS), antivirus, logging agents, sensors, etc.) to impair or reduce visibility of defensive capabilities.

6. T1027.013 Encrypted/Encoded File Stealth

   What they do: xinglocker encrypts files using encoded formats to ensure data impact and hinder recovery.

   What that means: Adversaries may encrypt or encode files to obfuscate strings, bytes, and other specific patterns to impede detection.

7. T1070.004 File Deletion Stealth

   What they do: xinglocker deletes critical files and shadow copies to maximize damage and prevent restoration.

   What that means: Adversaries may delete files left behind by the actions of their intrusion activity.

8. T1018 Remote System Discovery Discovery

   What they do: xinglocker performs remote system discovery to identify targets within the victim network.

   What that means: Adversaries may attempt to get a listing of other systems by IP address, hostname, or other logical identifier on a network that may be used for Lateral Movement from the current system.

9. T1057 Process Discovery Discovery

   What they do: xinglocker performs process discovery to identify active processes for targeting or disabling.

   What that means: Adversaries may attempt to get information about running processes on a system.

10. T1083 File and Directory Discovery Discovery

    What they do: xinglocker discovers files and directories to select targets for encryption and impact.

    What that means: Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system.

11. T1021.002 SMB/Windows Admin Shares Lateral Movement

    What they do: xinglocker moves laterally via SMB/Windows Admin Shares to compromise additional networked hosts.

    What that means: Adversaries may use Valid Accounts to interact with a remote network share using Server Message Block (SMB).

12. T1041 Exfiltration Over C2 Channel Exfiltration

    What they do: xinglocker exfiltrates stolen data over C2 channels before deploying ransomware.

    What that means: Adversaries may steal data by exfiltrating it over an existing command and control channel.

13. T1486 Data Encrypted for Impact Impact

    What they do: xinglocker encrypts victim data for impact to force ransom payments and disrupt operations.

    What that means: Adversaries may encrypt data on target systems or on large numbers of systems in a network to interrupt availability to system and network resources.

14. T1489 Service Stop Impact

    What they do: xinglocker stops critical services and processes to disrupt victim operations during encryption.

    What that means: Adversaries may stop or disable services on a system to render those services unavailable to legitimate users.

15. T1490 Inhibit System Recovery Impact

    What they do: xinglocker inhibits system recovery by destroying Volume Shadow Copies and backup mechanisms.

    What that means: Adversaries may delete or remove built-in data and turn off services designed to aid in the recovery of a corrupted system to prevent recovery.

Software Xinglocker has been seen using, grouped by what it is used for. Legitimate administration tools appear here because these actors routinely abuse them — presence in this list is not itself malicious.
