On June 16th, the Slow Mist security team recently reported a major incident: an investor purchased a cold wallet through a short video platform, resulting in the theft of cryptocurrency assets worth 50 million yuan. The wallet had been pre-set with a backdoor by hackers during private key generation, and the assets were completely emptied within hours. Such "fake cold wallets" are common, especially hardware wallets purchased through unofficial channels, which are easily tampered with and pose significant risks.
The truly secure approach is: generating private keys offline, manually writing down the seed phrase, storing it physically isolated, away from power sources and networks, to be considered a "genuine cold wallet". Unfortunately, most users find it difficult to do this, ultimately leading to tragedy due to momentary carelessness or convenience-seeking.
