FBI: Infrastructure Used to Manage Domains Related to Cryptocurrency Investment Fraud Scams between October 2023 and April 2025


The Federal Bureau of Investigation (FBI) is releasing this FLASH to disseminate indicators of compromise (IOCs) associated with malicious cyber activities linked to Funnull Technology Inc. (Funnull).

Ultimately, money sent to these platforms is not invested, and instead goes directly to the scammers. Funnull facilitates these scams by purchasing IP addresses and providing hosting services and other internet infrastructure to groups performing these frauds.
