#数字货币市场回调 Last year, that group of Lazarus Hackers pulled off another big one. Billions of dollars, just hearing about it is painful. $BTC holders should be more cautious.

How did they get started? The trick is actually not new – disguising as emails like lecture invitations or interview notifications; as soon as you open the attachment, you've fallen for it. Sounds low? But it works, nonetheless.

The data recently uncovered by the South Korean cybersecurity company AhnLab is even more alarming. In February of this year, a leading exchange was hacked for $1.4 billion, and it is basically confirmed that this group was behind it. There is also a strong suspicion regarding the $30 million vulnerability attack on Upbit in Korea. The professionalism of these guys is indeed not to be taken lightly.

What's more troublesome is that with the advancement of AI technology, phishing attacks are becoming increasingly difficult to defend against. Emails are written to look real, and links are disguised seamlessly.

AhnLab's advice is quite practical: enterprises should invest in multi-layer protection without worrying about costs, individual users should enable multi-factor authentication, avoid clicking on suspicious links, and only download from official channels. In this day and age, being cautious is always a good idea. After all, once your wallet is emptied, there won't be time to cry.
