curl attack prevention

K.
Hello all!

Can you write me some code which let me sleep calm during the night
and what should I do to prevent some attackers from using curl function?

In Poland there is a big portal which become famous and some attackers
attacked it by using curl function and get all data about users.

Can you wirte me what should I do to prevent my portal from such attack?

Maybe id session regenerating is one of the thing which I should apply after
new login?

Thank you in advance

Well, nothing special about curl.
It is just PHP's way of making http requests.

If the portals are hacked, they are NOT HACKED via Curl, but just USING
Curl.
The portals were unsafe to start with.

Yes, I have made a mistake with saying that they are hacked via curl.
I meant that how to prevent from hacking by using curl.

What things should I apply to make my site safe and be sure that nobody
who uses curl will not hacked my site?

Please answer.
I will be very grateful for help

Safety is not a command-line switch. Safety is looking what needs to be
done and exclude the rest. Like regenerating the session IDs. You should
always do that upon changing the user rights.
Also, take a good look at the file settings and look if sensitive files
are accessible from outside. Look at the possibility of SQL injection if
you use a database, and command-line injection if you call external
programs, e-mail injection if you send mail, etc.

And please don't expect our crystal balls to work if you even don't tell
us what OS you are using.

Safety is details and guarding those details.

Good luck,

The same way you prevent every other type of HTTP mediated attack.

Stop obsessing about Curl.

If you're having trouble understanding how the attack worked then tell
us where we can get more info on it.

Otherwise try google for 'PHP security'

You can't. You can't even tell if the user is using cURL, unless he
tells you.

Make your site safe and no one will be able to hack it - with or without
cURL. But if it isn't safe, it can be hacked - with or without cURL.

I am trying to create a generic function I can call to download all files from a single remote FTP directory -- using CURL. I want to multi-thread it, but need to get the single thread functionality working first before I tackle that. Anyway, in my function I can list all the files, but the function I have, no matter how I try, will only return one file -- the last file. My for() loop seems pretty straightforward, so not sure why only the...
