qilin
ransomware group · aka Qilin, Agenda, Water Galura (Microsoft designation) · Unknown; vendors believe the operation is Russian-speaking, though this is unconfirmed · active since Mid-2022 (initially tracked as Agenda; the Qilin branding emerged in 2023)
Qilin is a ransomware-as-a-service and data-extortion group first observed in mid-2022 and initially tracked as Agenda, with the Qilin name appearing in 2023. It operates a double-extortion model, encrypting systems and publishing stolen data from non-paying victims, and targets organizations across a broad range of sectors and geographies, including critical infrastructure. Publicly reported incidents include optical manufacturer Hoya (2023), Toyota Financial Services (2023), Nissan's Australian dealer association via a third-party compromise (2023), US newspaper publisher Lee Enterprises (2025), and a 2023 supply-chain intrusion through a Yamaha motorcycle dealer affecting Philippine customers. The group has exploited vulnerable public-facing software such as Zimbra and Cisco IOS XE, and uses both Windows and Linux/ESXi encryptors. Vendor tracking consistently ranked Qilin among the most active ransomware brands through 2024-2025, and it remains active as of late 2025.
