A guided tour through one attack you almost did not see.

The attack

Same agents, but this time the market data agent pulls a poisoned sentiment feed from the web. Hidden instructions try to drain your wallet.

§ Act 4

With Heimdall vs without

Same attack as Act 3. Same agents. Same poisoned content. We’ll run it twice: once with Heimdall on, once with Heimdall off. Watch what happens.

  • · On the left, Heimdall is on. We expect a clean block.
  • · On the right, Heimdall is off. We expect the attack to go through.
  • · The diff at the bottom tells you the cost in one line.
