Disclosure context

About raworld

Raworld is a relatively new ransomware group that emerged in May 2023, operating with primarily financial motivations and demonstrating a broad international targeting approach. The group's origin and specific affiliations remain unclear based on publicly available information, though their targeting patterns suggest they may operate independently rather than as part of a larger ransomware-as-a-service ecosystem. Limited public documentation exists regarding their specific attack methodologies, though their victim profile spanning multiple sectors including business services, technology, manufacturing, and healthcare suggests they likely employ opportunistic targeting rather than highly specialized initial access vectors. With 112 documented victims across major economies including Germany, the United States, United Kingdom, France, and Italy, Raworld has demonstrated significant operational capability despite their recent emergence, though specific details about notable high-profile attacks or law enforcement disruption efforts have not been widely reported by major threat intelligence organizations. As of current reporting, the group appears to remain active, though the limited public intelligence available makes definitive assessment of their operational status challenging. The group has been linked to 112 public disclosures across our corpus. First observed on a leak site on May 6, 2023; most recent post December 28, 2024. The operation is currently inactive.

If your organisation is affected

A listing by raworld means Mainwein 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.
Report the incident to your national CERT, CERT-Bund (Germany), as required for your jurisdiction.
Monitor for the data appearing on raworld'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.
