120,000 Bitcoin (BTC) Wallets at Risk With This Vulnerability
The post 120,000 Bitcoin (BTC) Wallets at Risk With This Vulnerability appeared on BitcoinEthereumNews.com.
Thousands of Bitcoin (BTC) wallets are prone to brute force attacks Three steps to make your funds safe Due to a known bug in the Libbitcoin Explorer (bx) 3.x library, over 120,000 Bitcoin (BTC) wallets globally can be hacked. A weak random number generation principle makes it easier for potential malefactors to guess seed phrases. Security researchers share some easy steps to protect your funds. Thousands of Bitcoin (BTC) wallets are prone to brute force attacks First discovered in November 2023, the vulnerability in Libbitcoin Explorer (bx) 3.x still makes non-custodial BTC wallets prone to brute force attacks. An overview of the potential hack vector was shared by the OneKey wallet team yesterday, Oct. 17, 2025. The vulnerability disclosed in the Milk Sad incident does not affect the mnemonic or private key security of any OneKey hardware or software wallet. Vulnerability Overview The issue originated from Libbitcoin Explorer (bx) 3.x, which generated random numbers using the Mersenne… pic.twitter.com/BsqhFIeNsl — OneKey (@OneKeyHQ) October 17, 2025 The library in question — a toolkit of software development instruments for Bitcoin (BTC) wallets in the C++ programming language — generated random numbers using the Mersenne Twister-32 algorithm seeded only by the system time. Since the seed space was limited to 2³² values in that case, the generated random numbers appeared to be more vulnerable to brute-force enumeration. As a result, wallets generated with certain versions of Trust Wallet and directly with Libbitcoin Explorer (bx) 3.x can be recovered by malefactors. Within a short time, attackers can derive private keys: Because the seed space is so small, a high-performance personal computer can enumerate all possible seeds within days, allowing attackers to predict private keys generated at arbitrary time points and steal assets on a large scale. As such, the weakness in RNG, despite being known…
