Xinof

MITRE ATT&CK does not currently catalogue Xinof, 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: xinof uses PowerShell scripts to execute malicious commands and payload deployment across compromised systems.

   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: xinof modifies Registry Run Keys to establish persistence and ensure recurring execution.

   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: xinof disables or modifies security tools like antivirus software to evade detection during its intrusion.

   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. T1070.004 File Deletion Stealth

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

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

5. T1018 Remote System Discovery Discovery

   What they do: xinof performs remote system discovery to map the victim network and identify high-value targets.

   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.

6. T1135 Network Share Discovery Discovery

   What they do: xinof performs network share discovery to identify accessible SMB shares for lateral movement and data 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.

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

   What they do: xinof leverages SMB/Windows Admin Shares for lateral movement between networked hosts.

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

8. T1486 Data Encrypted for Impact Impact

   What they do: xinof encrypts victim files using its ransomware payload to maximize impact and force ransom payment.

   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.
