In the first half of 2025, hacker activities in the crypto market were frequently in the headlines. The data is shocking: the amount stolen in six months exceeded 24 billion, with over 300 security incidents, more than the entire previous year. Even more heartbreaking is that over 70% of the losses did not come from exchange attacks, but from mistakes made by retail investors themselves.

Why do hackers specifically target retail investors? Frankly, they don't need advanced techniques. Phishing links, malicious authorization, impersonating customer service—these three tactics are enough. Especially when you're rushing to place orders, harvest rewards, or performing frequent operations, your defenses are most likely to collapse. Hackers have already calculated your judgment vulnerabilities during busy times, waiting for you to let your guard down.

The most common trap is the "signature authorization" pit. Many people, when operating decentralized applications, habitually click confirm when the wallet pop-up appears, without paying attention to whether it's "unlimited authorization" or "single authorization." Hackers exploit this loophole, tricking you into approving malicious contracts. Once signed, they can repeatedly transfer your assets without asking for your further approval.

So, the core logic of protecting yourself is simple: requests involving "full authorization" or "unlimited permissions" should be ignored immediately—close them without a second thought; always use a separate temporary wallet when testing new applications; do not casually interact with your main asset account; regularly review authorization records and revoke unnecessary permissions promptly. Making money is hard; safeguarding your assets is the most important.
