Mitigating Denial of Wallet risks with Vercel
Blog post from Vercel
Vercel is building controls and anomaly detection to help defend against Denial of Wallet (DoW) attacks, which focus on draining a service's operational budget by exploiting cloud scalability. DoW attacks inflate resource consumption to inflict financial damage, unlike traditional cyberattacks that target code or infrastructure vulnerabilities. These attacks exploit auto-scaling applications by generating illegitimate requests while staying below rate-limiting thresholds, leading to unnecessary scaling of cloud resources and inflated service costs. Vercel's secure by default platform provides granular API rate limiting, a Web Application Firewall (WAF) to filter malicious traffic, real-time monitoring, and configurable spending limits to proactively manage costs, as well as advanced bot protection through behavioral analysis and challenge-based verification.
