About Abyss

Abyss is a relatively new ransomware group that emerged in March 2023, operating with primarily financial motivations and targeting organizations across multiple sectors with a focus on English-speaking countries. The group's origin and affiliations remain largely undocumented by major security agencies, though their targeting patterns suggest they operate independently rather than as a Ransomware-as-a-Service model. Their attack methodology and specific tools have not been extensively documented by major threat intelligence firms, though their victim profile of 87 organizations indicates they employ effective initial access techniques to compromise business services, technology, healthcare, and agriculture sectors. The group demonstrates a clear geographic preference for targets in the United States, United Kingdom, Canada, Switzerland, and Hong Kong, suggesting either language preferences or specific regional access capabilities. Due to the group's recent emergence and relatively limited public documentation from established security researchers, detailed information about notable campaigns, encryption methods, or law enforcement actions remains scarce. Abyss appears to remain active as of current reporting, though the lack of extensive public analysis by major threat intelligence organizations suggests they may operate at a smaller scale compared to more prominent ransomware families. The group has been linked to 98 public disclosures across our corpus. First observed on a leak site on March 21, 2023; most recent post May 18, 2026. The operation is currently active.

About the victim

AI dossier — public-source company profile

Crown Laboratories, founded in 2000 and headquartered in Johnson City, Tennessee, develops and provides pharmaceutical, ethical OTC, and science-based skincare products to the medical marketplace, as well as contract manufacturing services to the pharmaceutical industry. The company operates a diverse portfolio spanning topical therapeutics, premium skincare, and medical devices across approximately 60 countries. Crown Laboratories has since merged with Revance Therapeutics to form Revance, a global aesthetics and skincare company.

Industry: Pharmaceutical & OTC Skincare Products / Contract Manufacturing
Address: Johnson City, TN, United States
Founded: 2000

Attack summary

Severity: critical — 8TB of data has been fully published by the group (data_published status, 15 data archives plus a filelist). The victim is a pharmaceutical and OTC/prescription products company, making it highly likely the exfiltrated data includes regulated information such as drug formulations, medical/prescription records, manufacturing data, and potentially patient or healthcare-provider PII — all qualifying as sensitive regulated data at significant scale.

The Abyss ransomware group claims to have exfiltrated 8TB of uncompressed data from Crown Laboratories and has published the data across 15 multi-part RAR archive files on their dark-web leak site, along with a file listing archive, indicating full data publication rather than a mere listing.
