Zerotolerance

MITRE ATT&CK does not currently catalogue Zerotolerance, 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: low. Treat it as orientation, not attribution.

1. T1059.001 PowerShell Execution

   What they do: zerotolerance executes malicious commands via PowerShell scripts to stage ransomware payloads and system modifications.

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

2. T1059.003 Windows Command Shell Execution

   What they do: zerotolerance uses Windows Command Shell (cmd.exe) to run batch files for service manipulation and file operations.

   What that means: Adversaries may abuse the Windows command shell for execution.

3. T1548.002 Bypass User Account Control Privilege Escalation

   What they do: zerotolerance bypasses Windows User Account Control prompts by injecting code into trusted processes.

   What that means: Adversaries may bypass UAC mechanisms to elevate process privileges on system.

4. T1685 Disable or Modify Tools Defense Impairment

   What they do: zerotolerance disables security tools and event logging mechanisms to evade detection and hinder incident response efforts.

   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.

5. T1027 Obfuscated Files or Information Stealth

   What they do: zerotolerance obfuscates malware binaries and configuration files using custom encoding to avoid static analysis detection.

   What that means: Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit.

6. T1070.004 File Deletion Stealth

   What they do: zerotolerance deletes Volume Shadow Copies and critical system files via native commands to ensure data recovery is impossible.

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

7. T1012 Query Registry Discovery

   What they do: zerotolerance queries the Windows Registry to identify persistence keys and system configuration for targeted modifications.

   What that means: Adversaries may interact with the Windows Registry to gather information about the system, configuration, and installed software.

8. T1486 Data Encrypted for Impact Impact

   What they do: zerotolerance encrypts victim files using a custom ransomware algorithm to maximize impact and extortion leverage.

   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.

9. T1489 Service Stop Impact

   What they do: zerotolerance terminates critical Windows services and processes to disrupt operational continuity before encryption.

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

10. T1490 Inhibit System Recovery Impact

    What they do: zerotolerance executes system recovery inhibition commands to prevent backup restoration and isolate compromised environments.

    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.
