I just wanted to open QQ Mail to send an email. As soon as I logged in, I was instantly dumbfounded: there were more than two hundred unread emails in my inbox. That alone would not have been scary, but what was terrifying was that they were all alert emails about failed login attempts to this site's admin panel. Didn't that mean someone was brute-forcing the password to this site's backend? Just thinking about it made me break out in a cold sweat, so I hurriedly checked the backend, only to discover that some hacker had not succeeded.

I looked at the contents of the emails and seemed to discover that the hacker trying to brute-force this site's backend was apparently called Angelina. But isn't it a bit stupid to use that username for the attack? Why would I use such a childish username?

It was not until I turned to the last few pages of my inbox that I discovered that, while brute-forcing this site, the hacker Angelina had also bombarded the site's email account, sending a large batch of spam messages to my inbox.

Although I did not suffer any losses this time, I have to complain about QQ Mail's filtering system. Out of several hundred spam emails, you freaking blocked only eight. I am utterly speechless.

After this lesson, I directly changed the password for this site's backend to a random 20-character combination of uppercase and lowercase letters, symbols, and numbers. Hackers, feel free to try harder next time.
