Zeppelin

MITRE ATT&CK does not currently catalogue Zeppelin, 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: zeppelin uses PowerShell to execute malicious payloads and propagate 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: zeppelin disables security tools like antivirus software to evade detection and analysis.

   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: zeppelin executes File Deletion routines to remove backups and shadow copies before encryption.

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

4. T1057 Process Discovery Discovery

   What they do: zeppelin runs Process Discovery commands to identify active services and processes for targeting.

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

5. T1135 Network Share Discovery Discovery

   What they do: zeppelin performs Network Share Discovery to locate victim file shares for encryption targets.

   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.

6. T1567.002 Exfiltration to Cloud Storage Exfiltration

   What they do: zeppelin exfiltrates sensitive healthcare data before deploying ransomware for extortion.

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

7. T1486 Data Encrypted for Impact Impact

   What they do: zeppelin encrypts victim files using a custom ransomware payload to hold data hostage.

   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.

8. T1489 Service Stop Impact

   What they do: zeppelin stops critical Windows services to disrupt system functionality during impact.

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

9. T1490 Inhibit System Recovery Impact

   What they do: zeppelin invokes Inhibit System Recovery mechanisms to prevent automated recovery 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.
