Ransomware

Daixin Team is a ransomware and data extortion group active since at least June 2022, known for targeting the healthcare sector, including hospitals, clinics, and related service providers. The group employs a double-extortion model—exfiltrating sensitive data before encrypting systems—and has leaked protected health information (PHI) to pressure victims. Intrusions often involve exploiting VPN vulnerabilities (notably in Fortinet FortiOS) and using compromised credentials for initial access. The ransomware uses AES for file encryption with RSA to protect the keys, and ransom notes direct victims to a Tor-based portal. The U.S. CISA, FBI, and HHS have issued joint advisories warning of the group’s impact on healthcare delivery and patient safety

Sicarii is a pro-Israeli/Jewish-branded ransomware-as-a-service operation that emerged in late 2025, explicitly targeting Arab and Muslim-majority organizations while avoiding Israeli systems, exploiting exposed RDP services and Fortinet devices, with its admin later instructing operators to migrate to the BQTLock platform.

Endurance is a destructive ransomware variant first observed in 2023, developed and operated by the threat actor known as IntelBroker (also referred to as Butler Spider). Rather than encrypting files for decryption, it functions primarily as a data wiper, overwriting file contents, appending randomized filenames, and then deleting the files altogether. The source code for the malware was intentionally made public by the operator, indicating its use as both a tool and a statement. Endurance was used in high-profile breaches, including targeting government agencies, large enterprises, and telecommunications providers.
