Bittensor was forced to halt its network activity on July 3 following a series of wallet drains that stole at least $8 million worth of digital assets.
The network outage aiming to contain the exploit was announced by Ala Shaabana, the co-founder of Bittensor, in a July 3 X <a href="https://x.com/shibshib89/status/1808306071263760612" target="_blank" rel="noopener nofollow">post</a>:
<blockquote data-ct-non-breakable="true">
 “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.” 
</blockquote>
Hacks and exploits remain among the most pressing concerns for the crypto space, delaying mass adoption. In the past 13 years, the crypto industry <a href="https://cointelegraph.com/news/crypto-hacks-19-billion-13-years">suffered nearly $19 billion worth of thefts</a>, with&nbsp;785 reported crypto hacks.

The theft was first discovered by pseudonymous onchain investigator ZachXBT in a July 3 Telegram message. He wrote:
<blockquote data-ct-non-breakable="true">
 “Bittensor was halted due to additional thefts earlier today potentially as a result of private key leakage.”
</blockquote>
The unknown address “5FbW” was exploited to obtain 32,000 Bittensor (TAO) tokens worth approximately $8 million.
This latest attack comes a month after a different wallet was drained for $11.2 million worth of TAO tokens on June 1, according to ZachXBT.

While smart contract vulnerabilities previously accounted for the lion’s share of hacked funds, <a href="https://cointelegraph.com/news/crypto-hacks-2024-private-key-leaks">private key leaks have surpassed</a> smart contract-related attacks.
Over 55% of the hacked digital assets were lost to private key leaks during 2023, <a href="https://info.merklescience.com/hackhub-report-2024" target="_blank" rel="noopener nofollow">according</a> to Merkle Science’s “2024 Crypto HackHub Report” report.

This is partly because hackers are vying for easier targets, according to Mriganka Pattnaik, co-founder and CEO of crypto risk and intelligence platform Merkle Science.
Pattnaik told Cointelegraph:
<blockquote data-ct-non-breakable="true">
 “While smart contract vulnerabilities remain a concern, hackers increasingly target areas outside smart contracts, like private key leaks. These leaks, often due to phishing attacks or insecure storage practices, have led to significant losses.”
</blockquote>
Meanwhile, hacked funds lost to smart contract vulnerabilities fell 92% to $179 million in 2023, down from a staggering $2.6 billion in 2022.
