Banks are not prepared for the industrialization of crypto theft

More friction needed with crypto to thrwart bad actors
So-called "Drainer-as-a-Service" platforms that allow low-skilled attackers to execute sophisticated cryptocurrency fraud schemes present a challenge to banks as crypto goes more mainstream, writes Karthik Narayanan, of Entrata.

While bank boards in 2026 are rightfully obsessed with the regulatory hurdles of stablecoin integration and AI-driven compliance, as the GENIUS act finds its foothold within the U.S., a more quiet and efficient revolution is occurring in the shadow economy. It is time we stop viewing crypto theft as a series of isolated hacks and start recognizing it for what it has truly become: a highly scalable model that mirrors the software-as-a-service platforms we use to run banks. If we do not adapt our defensive architecture to counter this "Shopify for theft," the friction of our traditional oversight will continue to be outpaced by the seamless user experience of the criminal enterprise.

The emergence of Drainer-as-a-Service, or DaaS, represents the industrialization of cybercrime. I have watched the evolution of value-exchange firsthand. The modern threat actor is no longer just a lone hacker; they are now platform owners, and their unit economics are becoming increasingly sophisticated. Just as Shopify democratized e-commerce by providing turnkey payment gateways and analytics to legitimate entrepreneurs, DaaS providers now offer sophisticated wallet-draining scripts to affiliates for a percentage of the stolen assets. These platforms offer high-performing, low-attrition tools that can be deployed across thousands of unique domains in minutes. This is not just a security breach; it is a business model disruption that allows low-skill actors to execute high-value heists with the same efficiency that a modern fintech uses to launch a new wallet feature.

Traditional banking compliance is currently ill-equipped to handle this level of speed and scale. I have deep respect for how regulations diverge across jurisdictions, having delivered products under the divergent rules of the U.S., Canada, Brazil and the EU. Yet, these regulatory frameworks move at a human pace, while DaaS platforms operate in real time. By the time a suspicious wallet address is flagged and blacklisted, the DaaS franchisee has already moved the assets through a decentralized mixer and spun up ten new domains.

To counter this, the banking industry must move beyond reactive compliance and toward architectural resilience. Instead of relying solely on static blacklists, we must treat fraud detection as a versioned, observable service in our architecture, utilizing machine learning to detect behavioral patterns such as the reuse of specific device fingerprints or anomalous settlement profiles.

In a new interpretive letter, the Office of the Comptroller of the Currency will allow banks to serve as middlemen for "riskless" crypto trades, extending existing brokerage authority for securities to digital assets.

We also need to implement technical patterns that protect consumers at the protocol level. For example, we should use "circuit breaker" patterns to gracefully prevent cascading issues across every critical flow in the payments ecosystem. A similar philosophy should be applied to wallet interactions. If a transaction signature deviates from a user's typical behavior — much like how we monitor for rent payment anomalies — the system should trigger an architectural circuit breaker that pauses the transaction before the funds leave the institutional custody.

As we plan for new rails, such as the stablecoin settlement projects, we cannot ignore the massive risk of DaaS. The goal is to improve settlement economics and shift costs, but doing so without a robust defensive platform is an invitation to disaster. We must co-create product road maps with risk and compliance teams, ensuring that engineering is a co-owner of the outcome.

The competition is no longer between banks; it is between platforms. The DaaS operators have built high-scale, real-time organizations that partner closely with their own versions of product and risk management. If we are to survive this shift, we must stop treating security as a checkbox and start treating it as a core architectural competency. We must build high-performing, resilient systems that can out-scale the industrialization of theft. Only by adopting an ownership mindset and applying first-principles thinking to our infrastructure can we hope to protect the future of the global payments value chain.
