Unlike traditional cyberattacks that target code or infrastructure vulnerabilities, Denial of Wallet (DoW) attacks focus on draining a service's operational budget. At Vercel, we're building controls and anomaly detection to help you defend against these threats and protect your applications. Link to heading What is a Denial of Wallet (DoW) attack? DoW attacks exploit cloud scalability to drive up operational costs. Introduced by OWASP in 2017 , these attacks inflate resource consumption—such as bandwidth or compute power—to inflict financial damage. Unlike Denial of Service (DoS) attacks, which disrupt availability, DoW targets your budget, threatening profitability and long-term sustainability. At its core, a DoW attack is an exhaustion of financial accounts, services, or credits on a cloud-based system. Without the proper protections, these attacks could erroneously charge organizations an uncapped amount. This is especially relevant in elastic cloud environments where costs scale with usage.…
