[C++] To String function

Mon, 30 Jan 2012 17:41:20 +0000

Okay, this may be noobish but I just now discovered the magical wonder of templates. With this new sorcery, I made a to string function. It converts whatever you give it to a string.

Code:

template

std::string tos(T x)

{

    std::stringstream y;

    y << x;

    return y.str();

}

Yeah, it's nooby, but I find it quite awesome xD

torrenting and private torrents

Wed, 25 Jan 2012 09:23:41 +0000

Are any of you guys interested in torrenting? I'm part of a private group that's invitation-based and has private torrents. I was wondering if you guys have anything to share to the torrenting community at http://egutorrents.me. We have hacking literature, games, ebooks, videos, music, and n0rp. All that's required is an email (you can send it privately via PM).

If you guys have anything to share to the hacking community, please feel free to PM me!

Does anyone here lurk around in projecteuler.net? It's a fun site with math challenges. I suggest using this thread as a place to share pseudocode and help each other on the challs.

Batch file fail

Mon, 02 Jan 2012 11:13:41 +0000

Hello, all remember that batch program i said i was making? well, i seem to have a problem i cant seem to fix and i was wondering if anyone could help.
the program revolves mostly around being able to do things to other peoples computer from your computer, and at the moment, i can only seem to get that to work with shutdown.exe, due to the /m \\ command. how ever taskkill or start commands do not have things like that, so im not sure how to make it affect other computers. i tried these line of code here:
echo Type the compter name of the victim here
set /p d=computername:

echo Type the victims program here
set /p a=program:

%w%=taskkill /F /IM %a%

net send %w% %d%

pause >NUL
goto start

When ever i run this, my in tensions were to the computer to take information from the taskkill line and then send that code to another computer to be executed there, how ever instead it executes the taskkill line on my computer as well. so what i need it something telling my computer to use that line for what it needs to do, but not execute it. any suggestions?

[C++] Finding Primes

Wed, 14 Dec 2011 04:55:16 +0000

When you are doing cryptography, you are often required to find large prime numbers. Seeing as I am horrible at math, I thought I might share this quick but ugly fix.

Quote:A prime is a number that is only evenly divisible by itself and one.

Numbers that can't be prime are 1 and everything below that.
The only even numbered prime is 2. No other prime is even.

The easiest way to check and see if a number is prime is to simply divide it by every number lower than it. If none of those numbers (between 2 & the number before itself) divide it evenly, then it is prime.

Here is an example of that:

Code:

int tprime(int test_num)

{

    int i;

    for (i = 2; i < test_num; i++)

    {

        if(test_num%i == 0) return false;

    }

    return test_num;

}

However, when numbers get really really big (which they do in a lot of cryptography algorithms), something like this will strain the computer to check for prime.

One way we can reduce that is to figure out which numbers we already know won't be divisible by it evenly. First off is even numbers. If it can be divided evenly, then there is no reason to check even numbers, seeing as 2 is the only even prime. That eliminates half of the work already.

Next is: What is the last possible divisible number in that set?

Say we have the number 100.
What is the highest number you can use to divide this evenly?
The answer is 50. Anything higher than half that number, and there is no way you can divide it evenly. So that is more work the computer doesn't have to do.

So lets try and implement these two ideas into the code I gave you above.

Code:

int tprime(int test_num)

{

    if (test_num == 2) return 2;

    if (test_num%2 == 0) return false;

    int i = 3;

    int sprime = test_num;

    test_num = ((test_num - 1) / 2);

    for (i; i < test_num; i++)

    {

        if(sprime%i == 0) return false;

    }

    return sprime;

}

The above solution found "1010033" (a 7 digit number) to be a prime in 0.104ms.
That however is no accomplishment what so ever. In certain cryptography algorithms, primes will be much larger than 7 digits long.

Anyways, I hoped you guys found this semi-useful. This isn't the best method of doing this by the way. It is only the best I can think of. There are many more complex and efficient algorithms for finding whether or not a number is prime. I just don't understand them at the moment, but I think what I presented was a very beginner level way to finding out if a number is prime. You can use it, just don't stop questioning if there is a better way to do it

BreakingSec Renaissance

Current Date: 12/13/11

Some changes to increase fun around the site!

1.) More posting
2.) Podcasts once every week
3.) Scheduled group IRC twice a week
4.) Virtual high fives and oreos
5.) More fun!

Okay I may have made number 4 up, but that shouldn't change the fact that we're going to have fun. The podcasts will start this week maybe by Thursday or Friday we can have one up for the public. The scheduled group IRC chats will begin next week.

Podcast: 12/15/11 or 12/16/11

IRC: 12/??/11 and 12/??/11

Post below on what time would be best for the group IRC's.

It's official. We're staying up

PHP tutorial 1

Sat, 10 Dec 2011 03:32:04 +0000

Here is a PHP tutorial for beginners, this will go over basic output with PHP.

PHP Code:

echo "This will be the output."; 

This above line will output the text "This will be the output" without the quotations

The entire code should look like:

PHP Code:

//Begin every code with this line
echo "This will be the output.";  //This is the output line of the code
?>                                        //This should be at the end of every code 

So that is probably one of the simplest things you can ever do with PHP.

I found this on the internet the other day looking for other hacking sites.

It's not really a hacker community, but more like webhost for skid tools(in spanish).
XP I find this great for learning Spanish.

May not be shutting down?

Fri, 09 Dec 2011 02:09:16 +0000

Due to an awesome friend willing to loan us the money to tide us over we most likely will not be shutting down. I would like to see action on this site get back to it's "pre-spam" levels in light of this news.

ALSO

I will be hosting a podcast along with several other people starting next thursday hopefully. It will be posted on breakingsec for anyone interested in listening.

Site Closing. [redacted]

Thu, 08 Dec 2011 09:10:17 +0000

From now until December 13th the site will continue to run as usual. On that day I am taking down the site and replacing it with a simple webirc/chat where people can drop by to have a final talk. I will be making a back up in case we find the funds to restart this in the future.

3Ethical/Breakingsec have been very important to me in the last 4 or 5 years. Not just the websites themselves, but the communities. I have seen hundreds of members pass through in and out, with a faithful few deciding to stick around. I have developed many strong friendships through this website which makes it even harder to see it go. We have been hacked 4 times. Had our site deleted 2 times, and yet still through adversity we thrived. Managing thousands of posts and regaining hundreds upon hundreds of members even after every single time.

We may not have been a major site, or boasted the most impressive hacking names on the internet, but infamy was never the goal of 3Ethicalhackers. We were there simply because we were brought together in the quest of knowledge, skill and for some of us, just the sense of community.

For me, this is like watching your house burn slowly. With nothing you can do about it except accept what's happening. 3Ethical will always be the most important group of individuals I've met online. And I will sorely miss every one of you. (Even Hacker99)

I hope that one day in the future I can come back here and restart this with more vigor and energy than I had showed it even in my more youthful days.

DOS

Mon, 05 Dec 2011 21:16:15 +0000

Hi all,
I'm new to hacking and I here a lot of people say (not particularly on this site but in general) that its very easy to run a DOS attack. So my question is, how do you run one? I understand the basic concept of it, but if anyone could include a tutorial of how to do one, then that would be very helpful. Also I understand that you can either DOS a website, or a computer through an IP address, whats the difference in running the two?
thanks guys,
Sam
