In sanctions law, economic resources means assets or services that are not cash but still have value: equipment, software subscriptions, cloud capacity, vehicles, real estate, professional services, or anything else that can be used to obtain funds, goods, or operational support. When a person or entity is listed, others are typically forbidden from making these resources available to them.
This matters in cyber security because attackers rely on infrastructure, access, and intermediaries. A sanctions regime can cut off hosting, payment processing, domain services, managed security tools, or contractor support that would help a malicious operator function. For defenders, the term is important in screening vendors, resellers, and service chains: even if no money changes hands, providing usable services to a listed party may be a compliance violation. In practice, cyber teams and legal teams use this concept to block support paths that keep hostile operations running.
