About the victim

AI dossier — public-source company profile

Revival Animal Health is a U.S.-based retailer and pharmacy specializing in pet healthcare products, vaccines, medications, and supplies for dogs, cats, horses, birds, and other animals. Founded in 1989 by Dr. Roy Nielsen, Jr., the company has expanded from pet vaccines to a broad line of products including prescription pharmacy services, reproductive supplies, and newborn animal care. It serves individual pet owners, breeders, shelters, and equine customers through its e-commerce platform at revivalanimal.com.

Attack summary

Severity: high — Data has been published (disclosed status: data_published), indicating confirmed exfiltration. The company operates a pharmacy and handles prescription records, which may include regulated health-adjacent data (pet prescriptions, customer PII, payment information), elevating severity above medium. Absence of confirmed human medical records or government data prevents a critical rating.

The AiLock ransomware group claims to have attacked Revival Animal Health and has published data ('data_published' status), though the leak post does not specify whether encryption, exfiltration, or both occurred, and no ransom amount or data size was stated.

Disclosure context

About AiLock

AiLock is an emerging ransomware group first observed in March 2026 with a primarily financial motivation, having targeted at least 24 known victims across multiple sectors. The group's origin and affiliations remain largely undocumented by major threat intelligence organizations, though their targeting patterns suggest a broad operational scope spanning the United States, Canada, Great Britain, China, and Germany. Based on publicly available information from security researchers, AiLock appears to focus on technology companies, consumer services, manufacturing, and public sector entities, though specific attack methodologies, initial access vectors, and encryption techniques have not been extensively documented by CISA, FBI, or major security firms. The group's relatively recent emergence and limited public documentation suggest they may be a smaller operation or newly formed entity, with no notable major campaigns or high-profile ransoms publicly reported by established threat intelligence sources. Given the March 2026 first observation date and lack of subsequent major public reporting, AiLock's current operational status and capabilities remain largely undetermined by mainstream cybersecurity organizations. The group has been linked to 38 public disclosures across our corpus. First observed on a leak site on March 3, 2026; most recent post June 4, 2026. The operation is currently active.

If your organisation is affected

A listing by AiLock means Revival Animal Health 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 AiLock'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.
