Executive Summary
Ransomware attacks against government agencies escalated significantly in the first half of 2026, with a 13% increase in incidents compared to the latter half of 2025. A report from Comparitech released on July 21, 2026, documented 187 attacks globally, averaging more than one per day. The United States was the most affected nation, though it saw a decline in attack numbers. A notable shift occurred in the threat actor landscape, with The Gentlemen ransomware group surging to become the most prolific attacker of public sector entities. This trend highlights the persistent and growing threat that ransomware poses to public services and the sensitive data they hold.
Threat Overview
Between January and June 2026, 187 ransomware attacks on government entities were recorded. Of these, 89 were publicly confirmed by the victims. The confirmed incidents resulted in the breach of at least 179,000 sensitive records, though the actual number is likely far greater due to underreporting.
Key statistics from the report include:
- Top Targeted Country: The United States, with 58 attacks (31% of the global total).
- Other Targeted Nations: Germany (9 incidents), France (8), and South Africa (6).
- Most Active Groups:
An interesting economic trend was the sharp decrease in the median ransom demand, which fell from $500,000 in H2 2025 to just $100,000 in H1 2026. This could indicate that attackers are shifting their strategy, finding it more profitable to target a larger number of smaller government entities that may be more likely to pay a smaller ransom quickly to restore services.
Technical Analysis
While the report does not detail specific TTPs for these attacks, ransomware campaigns against government entities typically rely on a few common initial access vectors.
-
Phishing: Spear-phishing campaigns (
T1566 - Phishing) are frequently used to trick government employees into revealing credentials or executing malicious payloads. -
Exploiting Public-Facing Applications: Government agencies run numerous public-facing services. Vulnerabilities in these applications, such as web portals or remote access solutions, are prime targets for exploitation (
T1190 - Exploit Public-Facing Application). -
Valid Accounts: Stolen or brute-forced credentials for remote services like RDP or VPNs provide a direct path into the network (
T1078 - Valid Accounts).
Once inside, the attackers engage in double extortion tactics, exfiltrating sensitive citizen and government data (T1537 - Transfer Data to Cloud Account) before encrypting systems (T1486 - Data Encrypted for Impact) to maximize pressure on the victim to pay.
Impact Assessment
Ransomware attacks on government entities have severe consequences beyond financial loss. They can disrupt essential public services, including emergency services, utilities, and administrative functions, causing significant harm to citizens. The theft of sensitive data, such as personal information from tax records or court documents, can lead to widespread identity theft and fraud. These attacks also erode public trust in the government's ability to protect their data and provide reliable services.

Cyber Observables — Hunting Hints
The following patterns could help identify ransomware activity in a government network:
| Type | Value | Description | Context |
|---|---|---|---|
| process_name | nltest.exe | Used for reconnaissance of domain trusts. | EDR process creation logs. |
| command_line_pattern | net group "Domain Admins" /domain | Command to enumerate privileged groups in Active Directory. | Windows command line logs (Event ID 4688). |
| network_traffic_pattern | RDP/SMB connections to multiple hosts from a single source | Indicates lateral movement attempts. | Network flow data, NDR systems. |
| file_name | *.locked or *.crypt | Common file extensions used by ransomware after encryption. | File integrity monitoring (FIM) systems. |
Detection & Response
- Endpoint Detection and Response (EDR): Deploy EDR across all servers and endpoints to detect malicious processes, script execution, and ransomware-like file activity (D3-PA: Process Analysis).
-
Active Directory Monitoring: Monitor Active Directory logs for signs of reconnaissance (e.g.,
nltest,net group) and privilege escalation attempts (D3-DAM: Domain Account Monitoring). - Backup Integrity: Regularly monitor the health and integrity of backups. Any attempt to access or delete backup files or servers should trigger a high-priority alert.
Mitigation
- Security Awareness Training: Given the prevalence of phishing, regular and practical training for employees is a critical first line of defense (M1017 - User Training).
- Patch Management: Government IT teams must be vigilant in patching vulnerabilities, especially on internet-facing systems, to close these common entry points (M1051 - Update Software).
- Network Segmentation: Implement robust network segmentation to separate critical systems and prevent attackers from moving laterally across the network after an initial compromise (M1030 - Network Segmentation).
- Immutable Backups: Maintain offline, encrypted, and immutable backups of all critical data and systems. Regularly test the restoration process to ensure a swift recovery is possible.
