Changpeng Zhao, the founder of Binance, has responded to the recent disclosure of a severe vulnerability impacting cryptocurrency wallets using Libbitcoin Explorer 3.x.
Binance CEO CZ Speaks Out After Libbitcoin Vulnerability
Due to a fault in the random number generator’s use of a 32-bit seed, it is inadequately random for modern cryptographic problems like GPUs, which is where the vulnerability comes from. CZ has made statements about this situation.
Serious Vulnerability in Libbitcoin Explorer 3.x
According to SlowMist, Distrust discovered a serious vulnerability on August 10 that affects cryptocurrency wallets using Libbitcoin Explorer 3.x. Through the use of the Mersenne Twister pseudo-random number generator (PRNG), this issue enables unauthorized access to private keys and has real-world effects.
The implementation of the PRNG in Libbitcoin Explorer version 3.x is where the vulnerability originates. This implementation uses a 32-bit system time as its seed and the Mersenne Twister algorithm. Through the use of brute-force techniques, attackers can quickly find a user’s secret key using this risky method.
This issue affects users of Libbitcoin Explorer 3.x and developers who use libbitcoin-system 3.6 to build libraries. Affected cryptocurrencies include Dogecoin, Solana, Litecoin, Bitcoin Cash, Zcash, Ripple, Ethereum, and Ripple.
