#Trust Wallet安全事件 Just finished reviewing the complete recap of the Trust Wallet private key vulnerability incident, and I really need to sound an alarm to everyone. The news that $1.5 billion worth of Bitcoin private keys were cracked may seem distant from us, but the underlying random number generation vulnerability has been threatening our wallet security all along.

Here's a clear summary for you: Weak random number algorithms (like Mersenne Twister) may seem advanced, but they simply cannot generate truly 256-bit random numbers; they only cycle within a limited range. This means hackers can quickly enumerate all possible weak private keys through brute force, directly unlocking your wallet—this is not a matter of probability, but an inevitable certainty.

Between 2019 and 2020 alone, over 53,500 BTC from Lubian mining pools fell into this dangerous zone, and 220,000 weak-key wallets are still continuously receiving assets. During the large-scale transfers at the end of December 2020, 136,951 Bitcoins were drained within hours, worth $3.7 billion. Although Trust Wallet later fixed the vulnerability, it was only publicly disclosed in April 2023 after being discovered in November 2022, during which hackers had already made multiple gains.

For us crypto enthusiasts, the lesson is very straightforward: when managing your own wallets, always use official wallets from reputable projects or hardware wallets. Don't be tempted to generate private keys with obscure tools just to save a few bucks. Before interacting with new projects, check their random number generation mechanisms. If you're unsure, use audited hardware wallets like Ledger or Trezor. The last point is crucial—regularly check the security of old wallet private keys, so that addresses created years ago don't become hidden risks.

No matter how low the security cost, it cannot be skipped. This is the first lesson for all crypto enthusiasts.
