Polkadot suffered a $1.38 million loss when an attacker resumed an exploit on October 26, using its own relayer before the XCM fix was applied.
The vulnerability had been addressed four months prior, but the attacker leveraged the earlier patch to trigger the loss, highlighting the risk of residual attack vectors even after code updates.
A subsequent network upgrade corrected the token supply without changing individual balances, ensuring that the broader ledger remained intact despite the breach.
During the 24‑hour period following the incident, DOT traded at $0.973256, up 4.0% according to Tradexus live data, indicating that market participants did not penalize the token heavily.
The episode underscores the importance of thorough post‑patch monitoring for blockchain protocols and may prompt validators to audit relayer configurations more rigorously.
