Major Exploit Rocks Bittensor: $8 Million in TAO Tokens StolenBittensor, a decentralized AI network, faced a significant exploit on July 2, 2024, resulting in the loss of $8 million worth of TAO tokens, equivalent to 32,000 TAO, according to blockchain investigator ZachXBT. This breach occurred due to a leaked private key, which allowed the attacker to drain assets from users' wallets. The incident began at 7:06 P.M. UTC, with the funds being transferred out swiftly. By 7:25 P.M. UTC, abnormal transfer volumes were detected, prompting the creation of a war room. Within 15 minutes, validators were placed behind a firewall, and safe mode was activated to prevent nodes from connecting to the chain, effectively neutralizing the attack by 7:41 P.M. UTC.Source: ZachXBTThe root cause was identified as a malicious package in the PyPi Package Manager, version 6.12.2, masquerading as a legitimate Bittensor package. This package contained code designed to steal unencrypted coldkey details and send them to a remote server controlled by the attacker. The Bittensor team quickly confirmed the incident and put the chain in "safe mode," allowing only block production while halting all transactions. Regular software updates were postponed until the chain could be fully restored. Co-founder Ala Shaabana assured that the attack had been contained and that the team was investigating all possibilities. Despite the exploit, some validators, such as RoundTable 21, reported their delegators' funds remained secure. By way of an update, we have contained the attack and put the chain into safe mode (blocks producing but no transactions are permitted).We’re still mid investigation and are considering all possibilities. Stay tuned.— Ala (@shibshib89) July 3, 2024 The immediate consequence was a 15% drop in the price of TAO, hitting a six-month low of $227 before slightly rebounding to $240, then falling again due to the bearish market sentiment at the time of writing. In response to the attack, Bittensor's developers paused all blockchain transactions to investigate and mitigate the issue. The OpenTensor Foundation (OTF) proposed burning 10% of the TAO supply to stabilize the token's price and restore confidence, with users invited to vote on the proposal. Bittensor Community UpdateYesterday at 7:41 PM UTC, we took the decision to place the Opentensor Chain Validators behind a firewall and entered safe-mode on Subtensor due to an attack that affected multiple participants in the Bittensor community.We have put together a…— Openensor Foundaion (@opentensor) July 3, 2024 This sparked a community debate on the decentralization claims of Bittensor, with critics arguing that the ability to halt the chain contradicted decentralization principles, while supporters deemed it necessary for asset protection.So Bittensor $TAO got halted after a number of wallets got drained (again).It might be a pro that the chain that can be halted is instances like this, but I think the reputation damage for a 'decentralized AI' protocol is more relevant. After all, if devs can switch off the…— Moerg 'Mo' (@Fibonaccious) July 3, 2024 The OTF outlined a recovery plan to gradually resume normal operations, with regular updates to the community. Users were advised to create new wallets and transfer their funds once normal operations resumed. Upgrading to the latest version of Bittensor was strongly recommended. - If you hold TAO on exchanges you are not at risk.- If you installed Bittensor 6.12.2 from source you are not at risk.- If you used a web wallet you are not at risk.- If you installed Bittensor 6.12.2 from PyPy but did not run any commands you are not at risk.- If you…— const (@const_reborn) July 3, 2024 To prevent future exploits, Bittensor plans to implement enhanced package verification processes, increase the frequency of security audits, adopt best practices in public security policies, and improve monitoring and logging of package uploads and downloads. These measures aim to bolster the security infrastructure and restore confidence in the TAO ecosystem. ConclusionBittensor's swift response to the $8 million TAO token exploit highlights the network's resilience and commitment to security. As the community debates decentralization principles, the planned security enhancements and recovery measures aim to restore trust and safeguard users' assets. FAQsWhat caused the Bittensor exploit?The exploit was caused by a leaked private key, allowing the attacker to drain $8 million worth of TAO tokens from users' wallets. It was traced to a malicious package in the PyPi Package Manager version 6.12.2, which stole coldkey details.How did Bittensor respond to the attack?Bittensor placed the chain in "safe mode," halting all transactions and allowing only block production. Validators were placed behind a firewall, and regular software updates were postponed until the chain could be fully restored.What was the impact on TAO's price?The price of TAO dropped by approximately 15%, reaching a six-month low of $227 before slightly rebounding to $240. This immediate consequence reflected the shock and subsequent efforts to stabilize the token's value.What measures are being taken to prevent future exploits?Bittensor will implement enhanced package verification processes, increase the frequency of security audits, adopt best practices in public security policies, and improve monitoring and logging of package uploads and downloads.
