Ransomware Group

RansomHub

Also known as: RansomHub Ransomware

Status: active • First seen 2024-02200+ known victims

RansomHub is the new kid on the block but they're growing fast. When BlackCat shut down, many of their hackers moved to RansomHub because it offers a better deal - affiliates keep 85% of the ransom. They've already hit hundreds of victims including major companies and seem to be taking over where other groups left off.

Overview

RansomHub is a rapidly growing ransomware-as-a-service operation that emerged in early 2024 and quickly became one of the most active groups. It attracted affiliates from defunct operations like ALPHV/BlackCat and offers an 85/15 profit split favoring affiliates, making it attractive to experienced operators.
