ThreatAI Analysis

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

About the Dragonforce group

DragonForce is a major ransomware-as-a-service operation first observed in August 2023 that launched a formal affiliate program offering 80% revenue share, then rebranded as a "ransomware cartel" in 2025, gaining notoriety for high-profile attacks on UK retailers Marks & Spencer, Co-op, and Harrods. Dragonforce has listed 636 victims since October 2022.

How Dragonforce is documented to operate

User Execution T1204 Execution

An adversary may rely upon specific actions by a user in order to gain execution. Users may be subjected to social engineering to get them to execute malicious code by, for example, opening a malicious document file or link. These user actions will typically be observed as follow-on behavior from forms of Phishing. While User Execution frequently occurs shortly after Initial Access it may occur at other phases of an intrusion, such as when an adversary places a file in a shared directory or on a user's desktop hoping that a user will click on it. This activity may also be seen shortly after Internal Spearphishing.

MITRE ATT&CK reference →
File and Directory Discovery T1083 Discovery

Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system. Adversaries may use the information from File and Directory Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions. Many command shell utilities can be used to obtain this information. Examples include <codedir</code, <codetree</code, <codels</code, <codefind</code, and <codelocate</code. Custom tools may also be used to gather file and directory information and interact with the Native API.

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.

Incident Analysis

Synmosa Biopharma was targeted by Dragonforce ransomware, one of the most active ransomware groups in our database with 629 confirmed victims globally. The attack was disclosed on April 27, 2026, when Synmosa Biopharma appeared on the group's dark web leak site.

Synmosa Biopharma is based in Taiwan , operating in the Healthcare sector. Taiwan ranks #14 globally for ransomware attacks, with 188 victims in our database.

Sector context: Healthcare organisations are high-value ransomware targets because patient data is extremely sensitive, regulatory penalties for breaches are severe, and operational downtime can threaten patient safety — all factors that increase ransom payment pressure.

Dragonforce 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 6, 2026 22:00 UTC.
