Spam and viruses are becoming more and more rampant, not only because mail plays a more and more important role in business, but also because of the low cost and high income of crime. In recent years, many wrongdoers have devoted themselves to making profits through e-mail fraud and come up with a variety of ingenious ideas, resulting in relevant service providers increasing their R & D investment in the field of security year by year to deal with possible loopholes and prevent them in case.

There are many users whose email client settings automatically load pictures, and many email users who can't resist curiosity to click. So this situation and users are taken advantage of by *. When they need to know the network situation of the * target, so as to adjust the * strategy and set * tactics, they will send an email to the * target and embed a 1X1-sized pixel image in the email, and the recipient will load the image saved on the * server when opening or forwarding the email. * the recipient is then lured to forward the email to the company's IT department, business department, finance department, etc., and when these departments receive the email, * know the relevant equipment information and IP address.
