Disclosure context

About Alphalocker

Alphalocker is a relatively new ransomware group that emerged in January 2024, operating with apparent financial motivations based on their targeting patterns across multiple sectors and countries. The group's origin and affiliations remain unclear due to limited public documentation from major threat intelligence sources, though their global targeting suggests a sophisticated operation. With 31 documented victims primarily concentrated in the United States, United Kingdom, Thailand, Brazil, and Italy, Alphalocker appears to focus on business services, technology, manufacturing, and healthcare sectors, indicating they likely seek targets with both valuable data and the financial capacity to pay ransoms. The group's attack methodology, encryption techniques, and specific tactics have not been extensively documented by major security researchers or government agencies, suggesting either operational security measures that limit visibility into their methods or their relative novelty in the threat landscape. Given the limited public reporting on notable campaigns or high-profile attacks, Alphalocker appears to operate below the radar of major law enforcement initiatives that typically target more established ransomware operations. The group remains active as of available intelligence, though the lack of comprehensive public analysis from established threat intelligence firms suggests they may be a smaller-scale operation or one that has successfully maintained a lower profile compared to more notorious ransomware families. The group has been linked to 61 public disclosures across our corpus. First observed on a leak site on January 24, 2024; most recent post May 30, 2026. The operation is currently active.

If your organisation is affected

A listing by Alphalocker means www.myriversidedentaloffice.com 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, CISA (United States), as required for your jurisdiction.
  • Monitor for the data appearing on Alphalocker'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.
