【Coin World】Do you remember that event that shook the entire encryption circle? The well-known hardware wallet manufacturer Ledger suffered a severe data breach in 2020. The hacker subsequently made public the customer information database stolen in June, involving over a million user email addresses.

This incident sounded the alarm for the encryption community at the time - even reputable hardware wallet service providers in the industry find it difficult to completely avoid data security risks. A large number of users' email addresses were leaked, followed by a surge in phishing attacks and scam emails.

This case reminds us of several key points: first, the private key security of the hardware wallet itself may not be an issue, but the surrounding user data also needs to be protected; second, even when choosing mainstream platforms, one must be vigilant against subsequent social engineering attacks and information fraud; finally, regularly updating security habits and enabling multi-layer protection is the long-term strategy. Now, five years have passed, and the importance of security protection has become even more prominent.

It's a good thing I didn't fill in my real email at the time, I avoided a disaster.

Oh no, Ledger really can't hold it together. Once a million email addresses were leaked, they directly became targets for scams.

This is why I never trust any big companies; no matter how tough the wallet is, it can't stop insiders.

The ledger situation is still too disappointing; even a big brand can't guarantee anything.

It's truly unbelievable that even Ledger can be compromised, and they still dare to say that hardware wallets are the most secure? --- When the million email leak happened, I almost fell for it too, but thankfully I reacted quickly. --- That’s why I say, no matter how big the platform is, it can't be relied upon; multi-signature wallets are the way to go. --- Five years in and still making the same mistakes? The security awareness in Web3 is really concerning. --- If this Ledger incident happened now, it would already be doomed; at that time, the community wasn't strong enough. --- Having a private key doesn't help if the email is leaked; it just becomes someone else's hunting ground. --- How can people still use Ledger? I've already migrated everything to Trezor. --- This is called a lesson, but most people just can't learn... they still don't even do their own research (DYOR). --- When the phishing emails were rampant, it was really annoying, and I still occasionally receive the altcoin versions. --- No matter how many layers of protection there are, you can't guard against human nature; the key is to recognize the risks.

The Ledger incident was really something, a million email addresses just leaked like that. It doesn't matter how well the Private Key is protected, once the email is exposed, it's game over.
