FAQs
The Office of Foreign Assets Control (OFAC) is a financial intelligence and enforcement agency within the U.S. Department of the Treasury. Its primary role is to administer and enforce economic and trade sanctions that support U.S. national security and foreign policy objectives by targeting foreign countries, regimes, terrorists, narcotics traffickers, and other threats.
A bulletproof hosting (BPH) provider offers internet hosting services with minimal regulatory oversight, designed to resist complaints and takedown requests. This enables cybercriminals to host illicit content (like malware, ransomware, and darknet markets) without interruption, making it difficult for law enforcement to disrupt their malicious operations.
OFAC identifies and tracks crypto-related cybercrime by including cryptocurrency addresses as identifiers in sanctions designations. They work with blockchain intelligence firms to trace transactions, analyze on-chain activity, and surface hidden connections between illicit actors and their digital assets. This allows for public attribution and aids compliance efforts by crypto sector participants.
