ThreatAI Analysis

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

About the Lynx group

Lynx is a ransomware-as-a-service operation that emerged in mid-2024 as a rebrand of INC Ransomware (whose source code was sold for $300,000 on the RAMP forum), claiming ~300 victims across manufacturing, business services, technology, and transportation with an 80/20 profit split for affiliates. Lynx has listed 416 victims since May 2023.

How Lynx 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.

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.

MITRE ATT&CK reference →
Disable or Modify Tools T1685 Defense Impairment

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. This may include stopping specific services, killing processes, modifying or deleting tool configuration files and Registry keys, or preventing tools from updating. This may also include impairing defenses more broadly by disrupting preventative, detection, and response mechanisms across host, network, and cloud environments.

Incident Analysis

Engineering Mechanics was targeted by Lynx ransomware, one of the most active ransomware groups in our database with 417 confirmed victims globally. The attack was disclosed on February 28, 2025, when Engineering Mechanics appeared on the group's dark web leak site.

Engineering Mechanics is based in China , operating in the Manufacturing sector. China ranks #26 globally for ransomware attacks, with 121 victims in our database.

Sector context: Manufacturing companies are frequently targeted because production downtime directly translates to financial loss. Ransomware operators exploit this time-sensitivity to demand higher ransoms and faster payment.

Lynx 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 22:00 UTC.

Frequently Asked Questions

Was Engineering Mechanics attacked by ransomware?

Yes. Engineering Mechanics was listed as a victim of the Lynx ransomware group on February 28, 2025. The organisation is based in China and operates in the Manufacturing sector. The disclosure appeared on the group's dark web leak site.

Which ransomware group attacked Engineering Mechanics?

Engineering Mechanics was attacked by Lynx ransomware. Lynx is one of the most active ransomware groups, having claimed 417 victims globally. The group typically employs a double-extortion model: encrypting the victim's files and threatening to publish stolen data.

When did the Engineering Mechanics ransomware attack occur?

The ransomware attack on Engineering Mechanics was disclosed on February 28, 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 Engineering Mechanics ransomware attack?

The specific data stolen from Engineering Mechanics 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 Manufacturing organisation, Engineering Mechanics likely held sensitive business data, client information, and operational records.

How can organisations protect against Lynx attacks?

To defend against Lynx 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.
