threat glossary

WebAssembly Malware

A malicious payload compiled to WebAssembly (WASM) to hinder analysis — used for cryptomining, skimmer obfuscation, and anti-analysis logic.

What it is

WebAssembly malware packages malicious logic into a compiled WASM module that runs in the browser at near-native speed. WASM is harder to statically analyze than JavaScript, so attackers use it for in-browser cryptomining, to conceal skimming logic, and for anti-analysis checks that decide whether to activate the second stage of an attack.

Real-world examples

  • WebAssembly Monero miners (2024–2025).
  • Skimmers obfuscating logic via a WASM blob.
  • WASM-based fingerprinting and anti-headless checks.

How ExploitShield detects it

WASM payloads loaded by a monitored page are flagged, the executing script's call stack is captured, and high-CPU-usage patterns or known mining-pool and exfiltration domains trigger an alert.
