Lockbit5

MITRE ATT&CK does not currently catalogue Lockbit5, 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: lockbit5 uses PowerShell to execute malicious payloads and spread ransomware binaries across compromised systems.

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

2. T1685 Disable or Modify Tools Defense Impairment

   What they do: lockbit5 disables antivirus tools and security software to prevent detection and ensure clean encryption execution.

   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.

3. T1070.004 File Deletion Stealth

   What they do: lockbit5 deletes Volume Shadow Copies and backup directories to eliminate recovery options for affected systems.

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

4. T1003.001 LSASS Memory Credential Access

   What they do: lockbit5 dumps LSASS memory using credential-access tools to harvest user credentials for lateral movement.

   What that means: Adversaries may attempt to access credential material stored in the process memory of the Local Security Authority Subsystem Service (LSASS).

5. T1110 Brute Force Credential Access

   What they do: lockbit5 employs brute force attacks against local accounts to gain initial access and persistence footholds.

   What that means: Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained.

6. T1057 Process Discovery Discovery

   What they do: lockbit5 runs process discovery commands to identify critical services and isolate high-value targets for encryption.

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

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

   What they do: lockbit5 leverages SMB/Windows Admin Shares to move laterally across networked manufacturing and engineering endpoints.

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

8. T1567.002 Exfiltration to Cloud Storage Exfiltration

   What they do: lockbit5 exfiltrates stolen data via encrypted C2 channels before deploying ransomware to maximize extortion leverage.

   What that means: Adversaries may exfiltrate data to a cloud storage service rather than over their primary command and control channel.

9. T1486 Data Encrypted for Impact Impact

   What they do: lockbit5 encrypts victim files using custom ransomware binaries, holding data hostage for extortion payments.

   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.

10. T1490 Inhibit System Recovery Impact

    What they do: lockbit5 calls system recovery inhibitors like kill.bat to prevent OS or backup restoration mechanisms from activating.

    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 Lockbit5 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.
