Unsafe

MITRE ATT&CK does not currently catalogue Unsafe, 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: unsafe executes malicious commands via PowerShell scripts to deploy payloads and manipulate system behavior.

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

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

   What they do: unsafe leverages registry run keys to maintain persistence by automatically launching malware on system startup.

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

3. T1685 Disable or Modify Tools Defense Impairment

   What they do: unsafe disables security tools like antivirus software and event log collectors to evade detection 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.

4. T1688 Safe Mode Boot Defense Impairment

   What they do: unsafe manipulates boot sequences to enter safe mode and disable critical recovery services during attack phases.

   What that means: Adversaries may abuse Windows safe mode to disable endpoint defenses.

5. T1027.013 Encrypted/Encoded File Stealth

   What they do: unsafe encodes victim data with symmetric encryption keys before exfiltration to protect stolen information.

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

6. T1070.004 File Deletion Stealth

   What they do: unsafe deletes Volume Shadow Copies and backup files via system commands to prevent recovery attempts.

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

7. T1018 Remote System Discovery Discovery

   What they do: unsafe performs remote system discovery to map internal networks and identify additional targets for lateral movement.

   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.

8. T1135 Network Share Discovery Discovery

   What they do: unsafe scans network shares using native tools to identify victim systems and data repositories for targeting.

   What that means: Adversaries may look for folders and drives shared on remote systems as a means of identifying sources of information to gather as a precursor for Collection and to identify potential systems of interest for Lateral Movement.

9. T1486 Data Encrypted for Impact Impact

   What they do: unsafe encrypts victim files using custom ransomware binaries, applying impact encryption across targeted directories.

   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: unsafe invokes system recovery inhibition commands to block forensic analysis and system restoration processes.

    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.
