Attack summary

Severity: critical — Confirmed large-scale exfiltration of sensitive corporate data from a publicly traded company (TPE:3032), including financial documentation and shareholder information. Attackers claim terabytes of data and demonstrate operational control of infrastructure. Alleged manipulation of stock market disclosures elevates severity.

The dragonforce group claims to have gained nearly total control of HEC Group's infrastructure weeks before the company's August 30 public disclosure. The attackers state they exfiltrated a vast amount of data spanning terabytes before encrypting systems. The group alleges that HEC Group's official statement minimizing the breach was false and intended to manipulate stock market trading.

What the group claims

On August 30, HEC Group issued an official statement addressed to shareholders of TPE:3032 and other stakeholders, announcing that the company had been the target of a cyberattack. In its statement, the company claimed that the breach was detected immediately, that high-tech countermeasures were deployed, and that no corporate documentation was lost. The incident was characterized as a minimal, random occurrence. The reality, however, is starkly different. Our operation against the company began weeks prior to that publication. Due to a systemic failure to implement basic security principles, we gained nearly total control over the infrastructure supporting the development and commercial operations of the entire corporate group. We conducted a methodical and comprehensive review of the documentation, exfiltrating a vast amount of data. We remained undetected for as long as necessary to secure everything we sought. Only after completing our objectives did we initiate the data encryption process, the company's technical staff did not even detect our presence until many hours later. At the time of their official announcement, HEC Group's leadership knew the statement was entirely false. Its sole purpose was to manipulate stock market trading. Instead of contacting us to mitigate the damage, management chose to deceive the exchange. When we finally managed to contact the company's leadership and offered them a chance to make their official statement more truthful in exchange for the deletion of the taken documents, they showed no interest. If the leadership of HEC Group has decided to pursue a path of selfdestruction, we will not stand in their way. To prove that HEC Group’s statement was a fabrication and that our claims are accurate, we will now publish a portion of the exfiltrated data. This initial release will consist of over 360,000 files, drawn from a total volume measuring in terabytes. This data will provide stock exchange regulators and partner companies with exhaustive evidence of the actual events. The remaining documents will not be released publicly at this time, as we have devised a more strategic use for them. While the countdown timer below this publication runs, the companies affiliated with HEC Group, their shareholders, and regulatory authorities have time to prepare. HEC Group has one final opportunity to accept our proposal and avoid the consequences.

Disclosure context

About Dragonforce

Dragonforce is a relatively new ransomware group that emerged in December 2023, operating with apparent financial motivations based on their targeting patterns and victim selection. The group's origin and potential affiliations remain unclear due to limited public documentation from established threat intelligence sources, though their rapid accumulation of 439 documented victims suggests either sophisticated capabilities or possible connections to existing ransomware infrastructure. Based on their targeting patterns across diverse sectors including manufacturing, business services, technology, and construction, Dragonforce appears to employ opportunistic attack methodologies, though specific initial access vectors, encryption methods, and extortion tactics have not been publicly detailed by major security firms or law enforcement agencies. The group has demonstrated a preference for targeting organizations primarily in English-speaking countries and Western Europe, with the United States, United Kingdom, Germany, Australia, and Italy representing their most frequent victim locations, suggesting possible language capabilities or geographic operational preferences. As of current reporting, Dragonforce appears to remain active given their recent emergence and ongoing victim acquisition, though the lack of detailed public analysis from major threat intelligence organizations indicates either operational security measures that have limited researcher visibility or that the group has not yet conducted sufficiently high-profile attacks to warrant extensive public documentation by CISA, FBI, or established security research firms. The group has been linked to 675 public disclosures across our corpus. First observed on a leak site on December 13, 2023; most recent post September 24, 2026. The operation is currently active.

If your organisation is affected

A listing by Dragonforce means HEC Group appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

  • Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
  • Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
  • Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
  • Monitor for the data appearing on Dragonforce's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
