Moved from The Lounge forum, accordingly to Website & Server Hacking.

am looking for effective methods for hacking websites

It's not possible to generalize attack vectors, without assessing and researching the security and vulnerabilities (If any) of the website(s) In question.

ok i get it, so it all depends on the vulnerabilities detected for each site ...

Correct.

There must be a flaw, some sort of weakness/vulnerability to allow exploitation and access the back-end thereafter. It's just a matter of Identifying their security loopholes. I've spent as long as two weeks on one site, and finally gained access.
