On August 2025, Hexotic was exploited in a input validation, resulting in approximately $500 in losses. That makes the Hexotic exploit the 446th largest DeFi incident out of 690 documented in our archive.
Attack Mechanics: How the Hexotic Input Validation Played Out
Exploit Class Applied to Hexotic
The Hexotic incident on August 31, 2025 is classified as a Input Validation. The contract accepts an attacker-controlled input it should have rejected. In the full archive, Hexotic is 1 of 21 documented input validation incidents.
Hexotic in Context
At $500, the Hexotic exploit is a minor (<$1M) event compared to the largest same-class incident in our archive — OrbitChain (2024) at $81M.
Prior Input Validation Before Hexotic
The nearest input validation incident before Hexotic was Moonhacker, 251 days earlier on December 23, 2024 ($318.9K lost). The same exploit class surfaced again within the input validation attack surface.
Hexotic Vulnerability Signature
The primary source categorises the Hexotic exploit specifically as “Incorrect Input Validation”. This narrower label is entity-specific: it reflects how the Hexotic contract failed, rather than the broad input validation pattern alone.
