Magento ver。 1.7.0.2价格是黑客入侵

Question

I am using Magento ver. 1.7.0.2. Some Hackers are hacking the website. They are decreasing the price 96% at evening and users are purchasing the item at cheaper price. I am not able to figure out magento 1.7.0.2 security threads. Please suggestion me how can stop this hack.

Is there SQL Injection? Any Script? Bot attack?

Please suggest the solution.
