Hacking Activity: Hack a WebServer Web server vulnerabilities A web server is a program that stores files usually web pages and makes them accessible via the network or the internet. A web server requires both hardware and software. Attackers usually target the exploits in the software to gain authorized entry to the server. Default settings— These settings such as default user id and passwords can be easily guessed by the attackers. Default settings might also allow performing certain tasks such as running commands on the server which can be exploited. Misconfigurationof operating systems and networks — certain configuration such as allowing users to execute commands on the server can be dangerous if the user does not have a good password. Bugs in the operating system and web servers— discovered bugs in the operating system or web server software can also be exploited to gain unauthorized access to the system.
In order to provide to security to any system, one should know as how a website can be hacked or what are the different methods that hackers can use to hack a website. In DDOS attack lots of attacking systems are used.
Lots of computers at the same time launch DOS attacks on the same target server. As the DOS attack is distributed on multiple computers, it is called as distributed denial of service attack. In order to launch DDOS attacks, the hackers use a zombie network.
A zombie network is a group on malicious computers on which the hackers quietly installed DOS attacking tools. Whenever the attackers want to launch an attack, they can use all of the computers of the zombie network to carry out an attack.
If there so many members in the zombie network, the attack will be more powerful and just by blocking few IP addresses one cannot survive. There are numerous tools available on Internet which are available free of cost to flood the server to perform an attack and few of the tools also supports zombie network as well.
Once you have downloaded it, extract the files and save it your desktop. If you would like to launch an attack on IP address than put up the IP address in the box and press the lock button just next to the text box you have filled.
In the port type, just put up the port on which you would like to launch attack and the method field select UDP. If you would like to attack on website keep the port as it is but change it for minecraft servers.
Revealing error messages are manna - they can carry invaluable table name and structural details. The following illustrative string is from Imperva.
Microsoft, MySpace, Google This is somewhat more complicated than SQL Injection, and we'll just have a quick look to get a feel for it.
The one thing I really need right now is to see an ad for cheap Cialis.
Maybe the linked page satisfies this craving, maybe not. Nothing dramatic happens when you click the link, at any rate, and the long day wears on. When a link in an IM, email, forum or message board is hexed like the one above, it could contain just about anything. Like this example, from SandSprite , which helps steal a session cookie, which can potentially be used to hijack a session in a web application, or even to access user account details.
Stealing cookies is just the tip of the iceberg though -- XSS attacks through links and through embedded code on a page or even a bb post can do a whole lot more, with a little imagination.
XSS is mostly of concern to consumers and to developers of web applications. It's the family of security nightmares which keeps people like MySpace Tom and Mark Zuckerberg awake at night.
So they're not all bad then, I suppose For additional resources on this topic, here's a great overview of XSS PDF and just what can be accomplished with sneaky links. And here's an in-depth XSS video. Authorization Bypass Authorization Bypass is a frighteningly simple process which can be employed against poorly designed applications or content management frameworks.
You know how it is So they build a content management framework for the Mickey Bags research department. Trouble is that this local portal is connected to other more important campus databases. Next thing you know, there goes the farm Authorization bypass, to gain access to the Admin backend, can be as simple as this: Find weak target login page. View source.
Save to desktop. Open on desktop. Enter anything into login fields, press enter. Hey Presto.
Here's a great video of a White Hat going through the authorization-bypass process on YouTube. This was done against a small university's website. It's a two-minute process. Note that he gets into the User 1 account, which is not the Admin account in this case.
Is Admin User 1 on your User table? Google Hacking This is by far the easiest hack of all. It really is extraordinary what you can find in Google's index. And here's Newsflash 1: you can find a wealth of actual usernames and passwords using search strings. Copy and paste these into Google: inurl:passlist.
Google hacking will primarily be used for finding sites with vulnerabilities. If a hacker knows that, say, SQL Server has certain exploits, and he knows a unique string pushed out by that version in results, you can hone in on vulnerable websites.
