Group Intelligence
- Dragonforce — DragonForce is a major ransomware-as-a-service operation first observed in August 2023 that launched a formal affiliate program offering 80% revenue share, then rebranded as a "ransomware cartel" in 2025, gaining notoriety for high-profile attacks on UK retailers Marks & Spencer, Co-op, and Harrods.
- Qilin — Qilin ransomware was first observed in July of 2022. Qilin Ransomware is written in Golang and supports multiple encryption modes; all of which are controlled by the operator.

- Nova — Nova (formerly RALord) is a ransomware-as-a-service (RaaS) group that encrypts victims’files and uses double-extortion tactics to pressure organizations into paying for decryption and data non-disclosure.
- Nightspire — NightSpire is a ransomware group that first emerged in March 2025 and rapidly claimed over 250 victims across retail, manufacturing, healthcare, finance, and education sectors in the US, France, India, Taiwan, and Japan, using aggressive double-extortion with ransom deadlines as short as two days.
