ThreatAI Analysis

Compiled from this incident record and the threat intelligence profile for Shinyhunters. Figures and technique mappings are quoted from the source data, not inferred.

About the Shinyhunters group

ShinyHunters is a financially motivated data-theft and extortion group active since 2020, responsible for high-profile breaches including Ticketmaster (via Snowflake) and PowerSchool; by 2025 they launched a RaaS offering called "shinysp1d3r," and in August 2025 French authorities arrested four members. Shinyhunters has listed 156 victims since April 2024.

How Shinyhunters is documented to operate

Data from Information Repositories T1213 Collection

Adversaries may leverage information repositories to mine valuable information. Information repositories are tools that allow for storage of information, typically to facilitate collaboration or information sharing between users, and can store a wide variety of data that may aid adversaries in further objectives, such as Credential Access, Lateral Movement, or Defense Evasion, or direct access to the target information. Adversaries may also abuse external sharing features to share sensitive documents with recipients outside of the organization (i.e., Transfer Data to Cloud Account).

Mitigations: User Training, Out-of-Band Communications Channel, User Account Management, Multi-factor Authentication, Software Configuration, Audit

MITRE ATT&CK reference →
Exfiltration Over Web Service T1567 Exfiltration

Adversaries may use an existing, legitimate external Web service to exfiltrate data rather than their primary command and control channel. Popular Web services acting as an exfiltration mechanism may give a significant amount of cover due to the likelihood that hosts within a network are already communicating with them prior to compromise. Firewall rules may also already exist to permit traffic to these services. Web service providers also commonly use SSL/TLS encryption, giving adversaries an added level of protection.

Mitigations: Restrict Web-Based Content, Data Loss Prevention

MITRE ATT&CK reference →
Data Encrypted for Impact T1486 Impact

Adversaries may encrypt data on target systems or on large numbers of systems in a network to interrupt availability to system and network resources. They can attempt to render stored data inaccessible by encrypting files or data on local and remote drives and withholding access to a decryption key. This may be done in order to extract monetary compensation from a victim in exchange for decryption or a decryption key (ransomware) or to render data permanently inaccessible in cases where the key is not saved or transmitted.

Mitigations: Data Backup, Behavior Prevention on Endpoint

Incident Analysis

coe.int was targeted by Shinyhunters ransomware, one of the most active ransomware groups in our database with 161 confirmed victims globally. The attack was disclosed on June 14, 2026, when coe.int appeared on the group's dark web leak site.

coe.int is based in France , operating in the Government & Defense sector. France ranks #6 globally for ransomware attacks, with 529 victims in our database.

Sector context: Organisations in this sector hold valuable data and operational systems that ransomware groups seek to exploit for financial gain through encryption and data exfiltration.

Shinyhunters typically employs a double extortion model: first exfiltrating sensitive data from the victim's systems, then deploying ransomware to encrypt files. Victims face two simultaneous threats — paying to restore access and paying to prevent publication of stolen data. The group's leak site publishes victim names and exfiltrated data as leverage.

Data source: This incident record is sourced from public ransomware group leak site disclosures aggregated via the ransomware.live API. Disclosure date reflects when the victim was published on the leak site, which may differ from the initial date of compromise. This platform does not publish or link to stolen data. Last data update: Sep 24, 2026 02:00 UTC.

Which ransomware group attacked coe.int?

coe.int was attacked by Shinyhunters ransomware. Shinyhunters is one of the most active ransomware groups, having claimed 161 victims globally. The group typically employs a double-extortion model: encrypting the victim's files and threatening to publish stolen data.

When did the coe.int ransomware attack occur?

The ransomware attack on coe.int was disclosed on June 14, 2026. This date reflects when the victim was published on the threat group's leak site, which may differ from the actual date of initial compromise.

What data was stolen in the coe.int ransomware attack?

The specific data stolen from coe.int has not been independently verified by this platform. Ransomware groups typically exfiltrate data before encrypting systems and use the threat of publication to pressure victims. As a Government & Defense organisation, coe.int likely held sensitive business data, client information, and operational records.

How can organisations protect against Shinyhunters attacks?

To defend against Shinyhunters and similar threat actors, organisations should: maintain regular offline backups tested for restoration; implement network segmentation to limit lateral movement; deploy multi-factor authentication on all remote access; use endpoint detection and response (EDR) tools; conduct regular phishing and security awareness training; and monitor threat intelligence feeds for indicators of compromise (IOCs) associated with active groups.
