Bittensor Identifies Malicious Package as Cause of $8 Million Drain
Bittensor, a decentralized AI network, experienced a severe security breach on July 2, which resulted in the theft of $8 million worth of TAO tokens.
The OpenTensor Foundation (OTF), the organization behind Bittensor, has taken swift action to mitigate the damage. In its July 3 postmortem report, the OTF identified a malicious package in the PyPi Package Manager as the root cause of the breach.

The breach affected users who downloaded the PyPi Package Manager version 6.12.2 between May 22 and May 29 and performed specific operations such as staking, wallet transfers, or delegation.
– 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
