DDoS attack on a MySQL server?

[funchatx]

My friend is having a lot [754.5+ GIB and increasing rapidly] of traffic sent to the level MySQL server since today. He had me help and see what is going on, and his MySQL server is saying that he has 754.5 GIB worth of traffic since this morning. Here is a screen shot:

The number is increasing very fast and I don't know what it is causing it. I think it is a DDoS attack.

Do you have advice on evading DDoS attacks?

If you're talking about a Free Hosting account, individual users don't "have a MySQL server"; those stats would be for ALL accounts combined. Remote MySQL access is not allowed in any case on Free Hosting (MySQL can only be accessed using the server name "localhost"), so the only way to access MySQL is through a web page/script hosted on the account(s), and page/script requests would reflect a DDoS attempt.

Why or how do you think - you as a user has 754.5+ GiB of MySQL storage ?

1 GiB = 1,073,741,824 bytes

so 754.5×1,073,741,824 = 810,138,206,208 Bytes of data

How much data is phpMyAdmin saying you have in that database?
