Approximately 97% of the initially identified minted tokens reached exchange deposit addresses before the exploit was publicly disclosed.

Subsequent on-chain analysis revealed that the full scope of forged token movements was significantly larger: one malicious wallet alone processed approximately 2.385 trillion ONE through 477 successful transfers in approximately 106 seconds.

The first was a quorum verification flaw: Harmony's consensus function IsQuorumAchievedByMask() measured len(mask.Publics) — counting public keys listed in the signature mask — rather than validating which validators actually signed. This reduced Byzantine Fault Tolerance to a length check on attacker-supplied data, allowing consensus messages carrying zero valid signatures to pass quorum verification and produce unauthorized token-minting blocks. The second was a replay protection weakness: proof fields in cross-shard receipts were not bound to signed block headers, allowing already-processed receipts to be resubmitted as new and trigger duplicate token credits. Together, these two flaws enabled the attacker to generate new ONE tokens through forged empty-block transactions without any corresponding on-chain debits. Harmony published the patch as GitHub PR #5101 and deployed emergency validator release v2026.1.1 on August 12, 2026. Halborn, a blockchain security firm, published a post-mortem analysis of the incident.","heading":"Technical Root Cause","sources":[{"url":"https://cryptoslate.com/harmony-weighs-a-full-blockchain-rollback-after-unauthorized-minting-floods-exchanges-with-billions-in-one/","name":"Harmony weighs a full blockchain rollback after unauthorized minting floods exchanges — CryptoSlate","type":"news_article","credibility":2},{"url":"https://defimon.xyz/blog/harmony-hack-august-2026","name":"Harmony Hack: 4 Billion ONE Minted in Supply Exploit (2026) — Defimon","type":"research","credibility":2},{"url":"https://www.halborn.com/blog/post/explained-the-harmony-hack-august-2026","name":"Explained: The Harmony Hack August 2026 — Halborn","type":"research","credibility":2}],"severity":"critical"},{"content":"The ONE token declined approximately 30–40% in the hours following public disclosure of the exploit.

Harmony stated that 'one fixed rollback window is the fairest and most secure' solution, and explained why alternative approaches were rejected: direct token burning was impractical because tokens had already dispersed across multiple destinations; blacklisting would preserve forged supply while potentially freezing legitimate assets; selective replay risked divergent transaction outcomes due to state differences; and token migration would cause substantially more disruption. The rollback would discard more than 109,000 regular transactions and 315 staking transactions recorded between the exploit and the rollback. Harmony noted that approximately 95.80% of those transactions (104,545 of 109,126) were automated activity — primarily DEX-related — and that the number of discarded transactions should not be treated as equivalent to the number of affected users. The network would use replacement databases rather than in-place rewind functions to ensure validators operated from identical reviewed states. Harmony confirmed rollback execution on August 18, 2026. Validators activated the second stage of the rollback procedure on approximately August 20, 2026 to restore network health.","heading":"Blockchain Rollback: Plan and Execution","sources":[{"url":"https://crypto.news/harmony-plans-chain-rollback-as-forged-one-spreads-across-network/","name":"Harmony plans chain rollback as forged ONE spreads across network — Crypto.news","type":"news_article","credibility":2},{"url":"https://crypto-economy.com/harmony-full-rollback-aug-11-forged-one-exploit/","name":"Harmony Plans a Full Rollback to Aug. 11 After Forged ONE Tokens Trigger Major Exploit — Crypto Economy","type":"news_article","credibility":2},{"url":"https://primexbt.com/news/harmony-plans-rollback-after-exploiter-forges-3-trillion-one-tokens/","name":"Harmony plans rollback after exploiter forges 3 trillion ONE tokens — PrimeXBT","type":"news_article","credibility":2},{"url":"https://www.crowdfundinsider.com/2026/08/298395-harmony-protocol-plans-network-rollback-after-token-forgery-exploit-raising-blockchain-immutability-and-lack-of-decentralization-concerns/","name":"Harmony Protocol Plans Network Rollback After Token Forgery Exploit — Crowdfund Insider","type":"news_article","credibility":2}],"severity":"high"},{"content":"The rollback decision prompted debate within the broader crypto community about blockchain immutability and the degree of centralization present in Harmony's validator set. Critics noted that the ability to execute a full chain rollback — discarding over 109,000 transactions — raised questions about whether the network's governance and validator coordination constituted a meaningful form of decentralization. Crowdfund Insider and other outlets reported these concerns explicitly. The incident drew comparisons to Flow blockchain's response to a similar situation in December 2025, when Flow ultimately abandoned a full rollback proposal in favor of targeted token burns after bridge operators and participants raised concerns about the effect on legitimate activity. Harmony proceeded with the full rollback rather than a targeted approach, citing the dispersal of forged tokens across DEX pools, bridges, contracts, and numerous wallets as making targeted recovery impractical.","heading":"Decentralization and Immutability Concerns","sources":[{"url":"https://www.crowdfundinsider.com/2026/08/298395-harmony-protocol-plans-network-rollback-after-token-forgery-exploit-raising-blockchain-immutability-and-lack-of-decentralization-concerns/","name":"Harmony Protocol Plans Network Rollback After Token Forgery Exploit, Raising Blockchain Immutability And Lack Of Decentralization Concerns — Crowdfund Insider","type":"news_article","credibility":2},{"url":"https://crypto.news/harmony-plans-chain-rollback-as-forged-one-spreads-across-network/","name":"Harmony plans chain rollback as forged ONE spreads across network — Crypto.news","type":"news_article","credibility":2}],"severity":"medium"},{"content":"This 2026 exploit is not Harmony's first major security incident. On June 23–24, 2022, Harmony's Horizon Ethereum Bridge was exploited for approximately $99.6 million in cryptoassets. In that incident, attackers compromised at least two of four private keys controlling the bridge's 2-of-5 multisig validator set and drained bridged assets, which were subsequently swapped for Ether and laundered through Tornado Cash. Blockchain analytics firm Elliptic attributed the 2022 Horizon Bridge hack to APT38, also known as the Lazarus Group — a North Korean state-linked threat actor — within days of the hack. The FBI confirmed this attribution in January 2023. The 2022 incident prompted significant criticism of the low multisig threshold and centralized key custody. The recurrence of a critical consensus-layer vulnerability in 2026 has intensified concerns about Harmony's long-term security posture, as noted by commentary in the Santiment community insights report referencing how the 2026 exploit 'revives Harmony's worst security memories.'","heading":"Prior Security History: 2022 Horizon Bridge Hack","sources":[{"url":"https://medium.com/harmony-one/harmonys-horizon-bridge-hack-1e8d283b6d66","name":"Harmony's Horizon Bridge Hack — Harmony Medium (official post-mortem)","type":"official","credibility":1},{"url":"https://www.elliptic.co/resources/harmony-horizon-bridge-hack","name":"The Harmony Horizon Bridge Hack — Elliptic","type":"research","credibility":1},{"url":"https://app.santiment.net/insights/read/one-exploit-revives-harmony-s-worst-security-memories-11160","name":"ONE Exploit Revives Harmony's Worst Security Memories — Santiment Community Insights","type":"research","credibility":2}],"severity":"high"},{"content":"As of the date of this investigation, several material facts remained unconfirmed by Harmony's team directly.
