Arvinclub is a relatively obscure ransomware operation that emerged in September 2021, primarily motivated by financial gain through extortion activities targeting organizations across multiple sectors. The group's origin and affiliations remain largely undocumented in public threat intelligence reporting, with limited information available from major security vendors or law enforcement agencies regarding their operational structure or whether they operate as a Ransomware-as-a-Service model. Based on available attack data, Arvinclub has demonstrated a diverse geographical targeting approach, with documented victims spanning Colombia, Iran, the United Kingdom, India, and Russia, suggesting either opportunistic targeting or the use of automated attack vectors rather than region-specific campaigns. The group has shown a preference for targeting manufacturing organizations, food and agriculture companies, financial institutions, and educational entities, accumulating approximately 35 known victims since their emergence. Their specific attack methodologies, including initial access vectors, encryption techniques, and data exfiltration practices, have not been extensively documented in public threat intelligence reports from major security firms. No significant high-profile campaigns, major law enforcement disruptions, or notable ransomware demands have been publicly attributed to this group by CISA, FBI, or established security research organizations. The current operational status of Arvinclub remains unclear due to limited public reporting and threat intelligence coverage of this particular ransomware variant. The group has been linked to 35 public disclosures across our corpus. First observed on a leak site on September 9, 2021; most recent post November 6, 2023. 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.
