A viral Node.js honeypot runs for six months and records every live exploit against a quiz game that draws 200K users in 2 weeks and 35K in 24 hours; documented attacks include score inflation by submitting repeated requests, timer manipulation, scraping-based DDoS and comment spam, and Node.js specifics: CPU-bound event-loop DoS, JSON query operator injection, and a V8 predictable math.random exploited to reverse MD5 reset passwords via rainbow tables; fixes include moved score calculation to server plus server-side validation and request flags.
