How Devman is documented to operate

Valid Accounts T1078 Stealth Persistence

Adversaries may obtain and abuse credentials of existing accounts as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion. Compromised credentials may be used to bypass access controls placed on various resources on systems within the network and may even be used for persistent access to remote systems and externally available services, such as VPNs, Outlook Web Access, network devices, and remote desktop. Compromised credentials may also grant an adversary increased privilege to specific systems or access to restricted areas of the network.

Exploitation of Remote Services T1210 Lateral Movement

Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network. Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. A common goal for post-compromise exploitation of remote services is for lateral movement to enable access to a remote system.

MITRE ATT&CK reference →
PowerShell T1059.001 Execution

Adversaries may abuse PowerShell commands and scripts for execution. PowerShell is a powerful interactive command-line interface and scripting environment included in the Windows operating system. Adversaries can use PowerShell to perform a number of actions, including discovery of information and execution of code. Examples include the <codeStart-Process</code cmdlet which can be used to run an executable and the <codeInvoke-Command</code cmdlet which runs a command locally or on a remote computer (though administrator permissions are required to use PowerShell to connect to remote systems).

Mitigations: Execution Prevention, Code Signing, Privileged Account Management, Antivirus/Antimalware, Disable or Remove Feature or Program

MITRE ATT&CK reference →
Exploitation for Client Execution T1203 Execution

Adversaries may exploit software vulnerabilities in client applications to execute code. Vulnerabilities can exist in software due to unsecure coding practices that can lead to unanticipated behavior. Adversaries can take advantage of certain vulnerabilities through targeted exploitation for the purpose of arbitrary code execution. Oftentimes the most valuable exploits to an offensive toolkit are those that can be used to obtain code execution on a remote system because they can be used to gain access to that system.

Mitigations: Application Isolation and Sandboxing, Exploit Protection, Update Software

MITRE ATT&CK reference →
Exploitation for Privilege Escalation T1068 Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges. Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. Security constructs such as permission levels will often hinder access to information and use of certain techniques, so adversaries will likely need to perform privilege escalation to include use of software exploitation to circumvent those restrictions.

Mitigations: Execution Prevention, Threat Intelligence Program, Application Isolation and Sandboxing, Exploit Protection, Update Software

MITRE ATT&CK reference →
Masquerading T1036 Stealth

Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools. Masquerading occurs when the name or location of an object, legitimate or malicious, is manipulated or abused for the sake of evading defenses and observation. This may include manipulating file metadata, tricking users into misidentifying the file type, and giving legitimate task or service names. Renaming abusable system utilities to evade security monitoring is also a form of Masquerading.

Incident Analysis

fassic.org was targeted by Devman ransomware, one of the most active ransomware groups in our database with 184 confirmed victims globally. The attack was disclosed on December 9, 2025, when fassic.org appeared on the group's dark web leak site.

fassic.org is based in France , operating in the Healthcare sector. France ranks #6 globally for ransomware attacks, with 517 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.

Devman 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 5, 2026 18:00 UTC.

Frequently Asked Questions

Was fassic.org attacked by ransomware?

Yes. fassic.org was listed as a victim of the Devman ransomware group on December 9, 2025. The organisation is based in France and operates in the Healthcare sector. The disclosure appeared on the group's dark web leak site.

Which ransomware group attacked fassic.org?

fassic.org was attacked by Devman ransomware. Devman is one of the most active ransomware groups, having claimed 184 victims globally. The group typically employs a double-extortion model: encrypting the victim's files and threatening to publish stolen data.

When did the fassic.org ransomware attack occur?

The ransomware attack on fassic.org was disclosed on December 9, 2025. 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 fassic.org ransomware attack?

The specific data stolen from fassic.org 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 Healthcare organisation, fassic.org likely held patient records, medical data, and personally identifiable information (PII).

How can organisations protect against Devman attacks?

To defend against Devman 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.
