VanHelsing is a recently emerged ransomware group first observed in March 2025, appearing to be financially motivated based on their targeting patterns and operational characteristics. Given their recent emergence and limited public documentation, details about their specific country of origin and affiliations remain unclear, though their targeting of multiple Western nations suggests they may operate from outside these jurisdictions. The group has demonstrated a preference for high-value sectors including healthcare, technology, and financial services, with attacks spanning the United States, Australia, Chile, France, and Italy, though their specific attack vectors and technical methodologies have not been extensively documented by major security firms or government agencies. With only eight known victims since their March 2025 emergence, VanHelsing appears to be a smaller-scale operation that may be conducting targeted attacks rather than broad spray-and-pray campaigns. The group remains active as of current reporting, though the limited public intelligence available suggests they have not yet achieved the notoriety or scale of more established ransomware operations. The group has been linked to 8 public disclosures across our corpus. First observed on a leak site on March 17, 2025; most recent post April 5, 2025. The operation is currently inactive.

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.
