Blackwater

MITRE ATT&CK does not currently catalogue Blackwater, 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: blackwater executes PowerShell scripts to deploy payloads and manipulate system processes.

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

2. T1112 Modify Registry PersistenceDefense Impairment

   What they do: blackwater modifies Windows Registry Run keys to establish persistence after initial compromise.

   What that means: Adversaries may interact with the Windows Registry as part of a variety of other techniques to aid in defense evasion, persistence, and execution.

3. T1685 Disable or Modify Tools Defense Impairment

   What they do: blackwater disables antivirus tools by terminating security processes and modifying service configurations.

   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: blackwater forces Safe Mode Boot to evade detection by security tools monitoring normal system operations.

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

5. T1070.004 File Deletion Stealth

   What they do: blackwater deletes Volume Shadow Copies via vssadmin /delete to prevent file recovery.

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

6. T1049 System Network Connections Discovery Discovery

   What they do: blackwater queries system network connections to map internal infrastructure before targeting.

   What that means: Adversaries may attempt to get a listing of network connections to or from the compromised system they are currently accessing or from remote systems by querying for information over the network.

7. T1135 Network Share Discovery Discovery

   What they do: blackwater scans network shares using net share commands to identify victim data for encryption.

   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.

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

   What they do: blackwater moves laterally through SMB shares to encrypt additional systems within the network.

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

9. T1486 Data Encrypted for Impact Impact

   What they do: blackwater encrypts victim files using a custom ransomware binary targeting critical organizational data.

   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. T1491.001 Internal Defacement Impact

    What they do: blackwater displays a ransom note and defaces web content on affected NGO and healthcare websites.

    What that means: An adversary may deface systems internal to an organization in an attempt to intimidate or mislead users, thus discrediting the integrity of the systems.

BLACKWATER

Your systems are encrypted.
After the attack, your company data has a new extension.

We stole confidential data from your infrastructure.

BLOG:
-If you don't contact us, information about the attack and your details will be published on the blog.

DATA: 
- We have personal data of employees, financial reports and other files from your network.

CONSEQUENCES OF THE LEAK:
-Financial losses include system restoration costs, fines, downtime, and asset value reduction. These costs exceed expectations and have long-term consequences for the business.
-Reputational damage includes loss of trust and media headlines. Reputation restoration requires more resources than system restoration.

ALARM:
1. DO NOT modify the files under any circumstances, otherwise the decryption program will not be able to recover your data.
2. DO NOT use third-party (other) software, as it may damage or modify the files.
3. To recover the files, you will need the decryption key or our decryption program.
4. The authorities will not help you, but will only increase your data risks.
