Hyperbridge’s $50,000 Treasure Hunt for Digital Ghosts!

by

A Tale of Woe and Bounty

  • Hyperbridge, that grand architect of digital bridges, hath unfurled its coffers on HackenProof, inviting the cunning and the curious to probe its depths.
  • For the discovery of critical vulnerabilities, a princely sum of $50,000 awaits the intrepid soul who dares to venture into the labyrinth of code.
  • The quest encompasses the arcane arts of cross-chain messaging and the sorcery of smart contracts, where logic flaws and reentrancy lurk like shadows in the night.

Behold, Hyperbridge, the brainchild of Polytope Labs, hath cast its net wide, summoning independent security researchers to scrutinize its runtime, pallets, and smart contracts. A bounty of up to $50,000 is promised for those who unearth the most grievous of vulnerabilities. “Come one, come all!” it declares, “For the Hyperbridge bug bounty is now live on HackenProof. Delve into our codebase and submit thy findings through the sacred portal of security!”

The Hyperbridge bug bounty program is now live on HackenProof.

Independent security researchers, heed the call! Review the Hyperbridge codebase and submit thy vulnerability reports through the hallowed platform.

This grand gesture cometh on the heels of a calamity most foul, wherein a nefarious exploit in April 2026 saw the pilfering of $2.5 million. The incident, involving the illicit minting of bridged Polkadot (DOT) tokens and their subsequent liquidation, laid bare the perils of cross-chain messaging and proof verification systems. Ah, the folly of man and machine!

The Hierarchy of Rewards and the Scope of the Quest

The rewards, like the layers of an onion, are tiered by severity:

  • Low severity findings-a mere $200, enough to purchase a modest repast.
  • Medium severity findings-$2,000 to $5,000, a sum fit for a week’s indulgence.
  • High severity findings-$5,000 to $15,000, a treasure to make one’s heart flutter.
  • Critical severity findings-Up to $50,000, a fortune to rival the Tsar’s coffers.

The scope of this grand endeavor encompasses the entire Hyperbridge protocol repository, including the elusive logic flaws, the treacherous access control, and the ever-present specter of reentrancy. Cross-chain message spoofing, state manipulation, and any threat to the integrity of messages or funds are fair game. Yet, beware! Theoretical vulnerabilities without proof, compiler version issues, gas optimizations, code style violations, and front-running attacks of limited impact are cast aside like yesterday’s borscht.

The rules of engagement are strict: disclosures must be made exclusively through HackenProof, with no direct contact with the team or public discussion of findings. Reports shall be reviewed, classified, acknowledged, and approved in due course. Once approved, the reward shall be transferred within three days, swift as a Cossack’s blade. Only the first reporter of a qualifying vulnerability shall be deemed worthy, and submissions must include detailed reproduction steps and proof-of-concept code where applicable. AI-generated reports sans runnable PoCs shall be cast into the void, unheeded and unrewarded.

The Post-Mortem of the Digital Calamity

Following the attack, Hyperbridge published a post-mortem so detailed it could rival the works of Pushkin. The report revealed that the attacker exploited a flaw in the Merkle Mountain Range (MMR) verifier, submitting a forged proof with an out-of-bounds leaf index. The verifier, poor thing, failed to detect leftover leaves after processing peaks, allowing the forged message to be accepted as valid and enabling the unauthorized drainage of funds from the Token Gateway contract. Ah, the folly of trust in a world of deceit!

In the aftermath, Polytope Labs conducted an internal review and commissioned Security Research Labs (SR Labs) to perform an independent audit. Both audits unearthed 14 vulnerabilities across the verification and settlement stack: 1 critical, 3 high, 5 medium, 4 low, and 1 informational. A veritable cornucopia of flaws, each more amusing than the last!

An Aggressive Gambit in the Face of Adversity

This bug bounty program is but the latest in a series of aggressive measures taken by Hyperbridge to fortify its defenses. By opening its code to the wider security industry, it seeks not only to mend its vulnerabilities but also to validate the foundational security of its Interoperable State Machine Protocol (ISMP). A bold move, indeed, akin to inviting the village to inspect one’s undergarments for holes!

Success in this endeavor may yet restore faith in Hyperbridge’s technology stack, paving the way for its implementation in Polkadot and other interconnected chains. Researchers eager to join this noble quest may find further details on the HackenProof page for Hyperbridge Protocol. Go forth, brave souls, and may your findings be as plentiful as the noses on Gogol’s characters!
