Down the Rabbit Hole: JS in Wonderland

Talkat Nordic.js 2017 · 2017-09-07..09-08· [javascript, security]

Shows how to generate digits and letters using only non‑alphanumeric tokens and then assemble and run code by abusing coercion and constructors, e g producing numbers from +![] and building identifiers via string indexing, then invoking code through [].filter.constructor() to execute arbitrary scripts. Provides concrete artifacts: an online converter and a full jQuery screwed rewrite. Demonstrates a real security implication where non‑alphanumeric payloads enable injection on a major site, so the technique is practical and works.
