Abyss Locker, tracked on this dashboard as 'abyss-data', is a ransomware and data-extortion operation first documented by vendor research in 2023, known for encryptors spanning Windows, Linux, and VMware ESXi environments. Trend Micro's 2023 analysis reported code overlap with the older HelloKitty family, and vendor, industry, and press reporting through 2024 highlighted attacks on virtualization, network-attached storage, and food and agriculture targets, including Taylor Farms and Moon Valley Nurseries. The group practices double extortion, publishing victims and stolen data on a Tor leak site; no ransom demands or payment totals have been publicly confirmed. Its leak-site listings skew toward mid-sized organizations across manufacturing, healthcare, real estate, and local government in multiple countries, including several US and German victims. Current activity is low: this dashboard recorded a single new victim since tracking began on 2026-08-26 (last post 2026-08-26), though the site lists roughly a dozen victims in total.

Tactics & tooling
  • Multi-platform encryptors covering Windows, Linux, and VMware ESXi (vendor research, 2023)
  • ESXi attacks reportedly shut down running virtual machines before encrypting datastores (Trend Micro, 2023)
  • Reported targeting of network-attached storage (NAS) devices (vendor research, 2023)
  • Double extortion: data theft plus encryption, with victims and stolen files published on a Tor leak site
  • Code overlap with the HelloKitty ransomware family indicates shared or recycled tooling (Trend Micro, 2023)
  • Opportunistic targeting of mid-sized organizations; 2024 industry alerts and press reporting flagged attacks on the food and agriculture sector
