Let's Hack the World

What is Session Hijacking ? Session hijacking is the act of taking control of a user session after successfully obtaining or generating an authentication session ID. Session hijacking involves an attacker using captured, brute forced or reverse-engineered session IDs to seize control of a legitimate user's Web application session while that session is still in progress. TCP session hijacking is when a hacker takes over a TCP session between two machines. Since most authentication only occurs at the start of a TCP session, this allows the hacker to gain access to a machine. Techniques : There are mainly three methods used to perpetrate a session hijack. These are: 1. Session Fixation: The session fixation attack is a class of Session Hijacking, which steals the established session between the client and the Web Server after the user logs in. Instead, the Session Fixation attack fixes an established session on the victim's browser, so the attack starts...

What is Sidejacking ? Sidejacking is the process of sniffing cookie information, then replaying them against websites in order to clone a victim’s session. We use the term sidejacking to distinguish this technique from man-in-the-middle hijacking. Whereas man-in-the-middle hijacking interferes with the original session, sidejacking does not. The victim continues to use his session blissfully unaware that we are also in his account. SideJacking works only if the site catches a non-SSL cookie, so any Web site that uses SSL exclusively would be safe from SideJackers. SideJacking was first demonstrated by Robert Graham , CEO of Errata Security at Black Hat in 2007. Techniques : All you need to do in order to sidejack is sniff cookies off the wire and edit cookies. This can be done with a wide variety of tools. 1. WinPcap is the industry-standard tool for link-layer network access in Windows environments: it allows applications to capture and transmit network packets by...

What is ARP ? The Address Resolution Protocol (ARP) is a computer networking protocol for determining a network host's hardware address (MAC) or link layer when only its Internet Layer (IP) or Network Layer address is known. In fact it’s a IP to MAC mapping. Broadcast ARP Request: Jessica, the receptionist, tells Word to print the latest company contact list. This is her first print job today. Her computer (IP address 192.168.0.16) wants to send the print job to the office's HP LaserJet printer (IP address 192.168.0.45). So Jessica's computer broadcasts an ARP Request to the entire local network asking, "Who has the IP address, 192.168.0.45?" Unicast ARP Reply: All the devices on the network ignore this ARP Request, except for the HP LaserJet printer. The printer recognizes its own IP in the request and sends an ARP Reply: "Hey, my IP address is 192.168.0.45. Here is my MAC address: 00:90:7F:12:DE:7F" ...

What is Session Fixation ? Session Fixation is an attack that permits an attacker to hijack a valid user session. The attack explores a limitation in the way the web application manages the session ID, more specifically the vulnerable web application. When authenticating a user, it doesn’t assign a new session ID, making it possible to use an existent session ID. The attack consists of inducing a user to authenticate himself with a known session ID, and then hijacking the user-validated session by the knowledge of the used session ID. The attacker has to provide a legitimate Web application session ID and try to make the victim's browser use it. Attack Scenario : 1. Mallory has determined that http://unsafe/ accepts any session identifier, accepts session identifiers from query strings and has no security validation. http://unsafe/ is thus not secure. 2. Mallory sends Alice an e-mail: "Hey, check this out, there is a cool new account summary fe...

How To Hack FACEBOOK ?   Today I'll illustrate the SESSION HIJACKING technique to hack FB Account. In this scope I will be using BACKTRACK , a Penetration Testing Distribution integrated with the below tools for Network Scan, MIMA and Packet Analysis. 1. NMAP 2. ARPSPOOF 3. WIRESHARK And two below scripts which are compatible with Mozilla Firefox will be used for Cookie Injection: 1. GREASEMONKEY 2. COOKIE INJECTOR Techniques:    1. First Scan your network and find the target using NMAP , a Network Scanner. In this case i got 192.168.1.3 as the Target. Backtrack 2. Next I need to start the IP Forwarding which enables my machine to forward any network traffic it receives from the target to the router. Backtrack 3.  Next Man-In-The-Middle-Attack (MIMA) is begun by exploiting ARP Cache Poisoning to intercept network traffic between the target and the router.    First  a malici...

Cookie Stealing Attack: Hack Any Account like Facebook ,Twitter , Gmail , Hotmail , Skype and yahoo etc. Using this method you can hack Any Account like Facebook , Twitter , Gmail ,Hotmail ,Skype and yahoo etc. this works At LAN( local Area Network ) . its best place to hack at university, cafe , public place where computer are on one LAN simple Example WI-Fi. What is Cookies And how the use of stealing cookies? Cookies are file’s that stored on Any computer’s By any website when a you visits them . the cookie used by the web server to check the authenticate the Real user . like you Enter Login in Facebook then a unique string’s Generated and the one copy saved in the web server and other is saved on your Browser as a Cookie file . both are matched when you open a Account. so then finally we will start .  Step 1: Download the Wire Shark and install it.  Step 2: Next open the wire shark and then click on interface.  Step 3: Next choose a interface w...
