I have to say that this wave of hacking operations is quite "professional ethics" - picking large investors to attack, and ordinary retail investors directly let them go.

If you can get the contact information of well-known people in the circle, there must be some doorway behind it. This precise targeting technique is obviously aimed at high-net-worth accounts. It is enough to catch a big fish, and the movement is still small, so you can run away when you close the net.

A typical upgraded version of social engineering is much smarter than a low-end scam that casts a net indiscriminately.
