Harmony Network Faces Crisis as Exploit Mints 4 Billion ONE Tokens

Harmony (ONE) has experienced a significant downturn, falling to an all-time low of $0.0005735 during early Asian trading on Wednesday. This drop follows a reported exploit that resulted in the unauthorized minting of roughly 4 billion ONE tokens, which constitutes about 26% of the token's total supply.

According to on-chain analyst Juiceberg, the minting occurred through empty blocks, with around 2.8 billion of the minted tokens quickly moving to exchanges. This influx of tokens contributed to a sell-off, leading to a 29% decline in ONE's price, which was trading near $0.00087 at the time of reporting.

In response to the incident, Harmony has coordinated with exchanges to freeze the funds associated with four identified wallet addresses linked to the exploit. The team is also working on a patch and evaluating rollback options to address the situation. Harmony's official communication stated, "We are working with our team and appropriate exchanges to stop and freeze the funds. We will update when we have new information."

This incident marks Harmony's second major security breach, following the Horizon Bridge attack in 2022, which resulted in the loss of approximately $99.6 million. The root cause of the current exploit has yet to be disclosed by Harmony.

To prevent further unauthorized minting, Harmony has released an emergency validator patch. The patch addresses vulnerabilities in cross-shard receipts, which previously allowed unauthorized transactions to go through. While the patch has been implemented, the network has not yet confirmed how it will handle the excess tokens already minted.

Latest Developments on Harmony's ONE Token Crisis

• Harmony's ONE token experienced a significant crash, plummeting approximately 40% after an exploit resulted in the unauthorized minting of around 4 billion tokens.
• This unauthorized issuance accounts for about 26% of the existing supply of ONE tokens, which stood at roughly 15 billion prior to the incident.
• In response, Harmony has released an emergency software update aimed at preventing further minting of tokens and has urged network operators to implement it immediately.
• Despite the update, Harmony is still assessing how to manage the tokens that were already created during the exploit.
• The network has temporarily paused its token bridge to mitigate risks associated with potentially compromised assets.
• Harmony has requested centralized exchanges to block and freeze funds linked to four specific wallet addresses tied to the exploit.
• The project is exploring rollback options to revert the blockchain to a state before the exploit occurred, which may eliminate the unauthorized tokens but could also affect legitimate transactions made afterward.
• As of now, the market remains bearish, with the ONE token trading above $0.00074 after briefly dropping to $0.000605.

New Developments in Harmony Network Crisis

• Harmony has identified 10,288 unauthorized transactions linked to the minting of fraudulent ONE tokens.
• Approximately 4 billion ONE tokens were minted, constituting about 26% of Harmony's total prior token supply.
• The exploit involved a vulnerability that allowed the attacker to bypass normal validation mechanisms by exploiting empty blocks.
• Roughly 2.8 billion of the minted tokens were quickly sent to various cryptocurrency exchanges.
• ONE token's price dropped between 26% and over 50% intraday following the exploit news.
• Harmony has implemented a software patch to address the vulnerability and paused its bridge to prevent further token movement.
• A potential rollback of the blockchain is being considered to erase the fraudulent transactions.
• This incident follows previous security breaches, including a $100 million exploit in June 2022 and an infinite mint bug affecting 150 million ONE tokens in late 2023.
