Posted in 7:19 AM

Everything over the internet is secured by the passwords. You need a login to do any stuff on any social or banking website. Passwords are the first security measure for these type of websites. So, I brought a tutorial on how to hack such sort of login passwords. This tutorial is based on credential harvester attack method. In which you will know about hacking passwords using credential harvester attack method.

HACKING PASSWORDS USING CREDENTIAL HARVESTER ATTACK

REQUIREMENTS

It's very simple and easy to follow. Before you start, you need the following things to work with.

Kali Linux OS
Target Website

STEPS TO FOLLOW

Run the Kali Linux machine. If you have not Kali Linux installed, you can grab a free copy and install it as a virtual machine. You can learn more about Kali Linux VirtualBox installation.
Sign in to Kali Linux by entering username root and password toor.

Cracking Windows 8/8.1 Passwords With Mimikatz

Posted in 10:51 PM

You Might have read my previous posts about how to remove windows passwords using chntpw and might be thinking why am I writing another tutorial to do the same thing! Well today we are not going to remove the windows user password rather we are going to be more stealth in that we are not going to remove it rather we are going to know what is the users password and access his/her account with his/her own password. Sounds nice...

Requirements:

A live bootable linux OS (I'm using Kali Linux)(Download Kali Linux)
Mimikatz (Download | Blog)
Physical Access to victim's machine
A Working Brain in that Big Head (Download Here)

Steps:

1. First of all download mimikatz and put it in a pendrive.

2. Boat the victim's PC with your live bootable Pendrive (Kali Linux on pendrive in my case). And open a terminal window

3. Mount the Volume/Drive on which windows 8/8.1 is installed by typing these commands
in the terminal window:

mkdir /media/win
ntfs-3g /dev/sda1 /media/win

[NOTE] ntfs-3g is used to mount an NTFS drive in Read/Write mode otherwise you might not be able to write on the drive. Also /dev/sda1 is the name of the drive on which Windows OS is installed, to list your drives you can use lsblk -l or fdisk -l. The third flag is the location where the drive will be mounted.

4. Now navigate to the System32 folder using the following command

cd /media/win/Windows/System32

5. After navigating to the System32 rename the sethc.exe file to sethc.exe.bak by typing the following command:

mv sethc.exe sethc.exe.bak

sethc.exe is a windows program which runs automatically after shift-key is pressed more than 5 times continuously.

6. Now copy the cmd.exe program to sethc.exe replacing the original sethc.exe program using this command:

cp cmd.exe sethc.exe

[Note] We made a backup of sethc.exe program so that we can restore the original sethc.exe functionality

7. With this, we are done with the hard part of the hack now lets reboot the system and boot our Victim's Windows 8/8.1 OS.

8. After reaching the Windows Login Screen plugin the usb device with mimikatz on it and hit shift-key continuously five or more times. It will bring up a command prompt like this

9. Now navigate to your usb drive in my case its drive G:

10. Now navigate to the proper version of mimikatz binary folder (Win32 for32bit windows and x64 for 64 bit windows)

11. Run mimikatz and type the following commands one after the other in sequence:

privilege::debug
token::elevate
vault::list

the first command enables debug mode
the second one elevates the privilages
the last one lists the passwords which include picture password and pin (if set by the user)

That's it you got the password and everything else needed to log into the system. No more breaking and mess making its simple its easy and best of all its not Noisy lol...

Hope you enjoyed the tutorial have fun :)

CEH: Fundamentals Of Social Engineering

Posted in 2:23 PM

Social engineering is a nontechnical method of breaking into a system or network. It's the process of deceiving users of a system and convincing them to perform acts useful to the hacker, such as giving out information that can be used to defeat or bypass security mechanisms. Social engineering is important to understand because hackers can use it to attack the human element of a system and circumvent technical security measures. This method can be used to gather information before or during an attack.

A social engineer commonly uses the telephone or Internet to trick people into revealing sensitive information or to get them to do something that is against the security policies of the organization. By this method, social engineers exploit the natural tendency of a person to trust their word, rather than exploiting computer security holes. It's generally agreed that users are the weak link in security; this principle is what makes social engineering possible.

The most dangerous part of social engineering is that companies with authentication processes, firewalls, virtual private networks, and network monitoring software are still wide open to attacks, because social engineering doesn't assault the security measures directly. Instead, a social-engineering attack bypasses the security measures and goes after the human element in an organization.

Types of Social Engineering-Attacks

There are two types of Social Engineering attacks

Human-Based

Human-based social engineering refers to person-to-person interaction to retrieve the desired information. An example is calling the help desk and trying to find out a password.

Computer-Based

Computer-based social engineering refers to having computer software that attempts to retrieve the desired information. An example is sending a user an email and asking them to reenter a password in a web page to confirm it. This social-engineering attack is also known as phishing.

Human-Based Social Engineering

Human-Based further categorized as follow:

Impersonating an Employee or Valid User

In this type of social-engineering attack, the hacker pretends to be an employee or valid user on the system. A hacker can gain physical access by pretending to be a janitor, employee, or contractor. Once inside the facility, the hacker gathers information from trashcans, desktops, or computer systems.

Posing as an Important User

In this type of attack, the hacker pretends to be an important user such as an executive or high-level manager who needs immediate assistance to gain access to a computer system or files. The hacker uses intimidation so that a lower-level employee such as a help desk worker will assist them in gaining access to the system. Most low-level employees won't question someone who appears to be in a position of authority.

Using a Third Person

Using the third-person approach, a hacker pretends to have permission from an authorized source to use a system. This attack is especially effective if the supposed authorized source is on vacation or can't be contacted for verification.

Calling Technical Support

Calling tech support for assistance is a classic social-engineering technique. Help desk and technical support personnel are trained to help users, which makes them good prey for social-engineering attacks.

Shoulder Surfing

Shoulder surfing is a technique of gathering passwords by watching over a person's shoulder while they log in to the system. A hacker can watch a valid user log in and then use that password to gain access to the system.

Dumpster Diving

Dumpster diving involves looking in the trash for information written on pieces of paper or computer printouts. The hacker can often find passwords, filenames, or other pieces of confidential information.

Computer-Based Social Engineering

Computer-based social-engineering attacks can include the following:

Email attachments
Fake websites
Pop-up windows

Insider Attacks

If a hacker can't find any other way to hack an organization, the next best option is to infiltrate the organization by getting hired as an employee or finding a disgruntled employee to assist in the attack. Insider attacks can be powerful because employees have physical access and are able to move freely about the organization. An example might be someone posing as a delivery person by wearing a uniform and gaining access to a delivery room or loading dock. Another possibility is someone posing as a member of the cleaning crew who has access to the inside of the building and is usually able to move about the offices. As a last resort, a hacker might bribe or otherwise coerce an employee to participate in the attack by providing information such as passwords.

Identity Theft

A hacker can pose as an employee or steal the employee's identity to perpetrate an attack. Information gathered in dumpster diving or shoulder surfing in combination with creating fake ID badges can gain the hacker entry into an organization. Creating a persona that can enter the building unchallenged is the goal of identity theft.

Phishing Attacks

Phishing involves sending an email, usually posing as a bank, credit card company, or other financial organization. The email requests that the recipient confirm banking information or reset passwords or PINs. The user clicks the link in the email and is redirected to a fake website. The hacker is then able to capture this information and use it for financial gain or to perpetrate other attacks. Emails that claim the senders have a great amount of money but need your help getting it out of the country are examples of phishing attacks. These attacks prey on the common person and are aimed at getting them to provide bank account access codes or other confidential information to the hacker.

Online Scams

Some websites that make free offers or other special deals can lure a victim to enter a username and password that may be the same as those they use to access their work system.
The hacker can use this valid username and password once the user enters the information in the website form. Mail attachments can be used to send malicious code to a victim's system, which could automatically execute something like a software keylogger to capture passwords. Viruses, Trojans, and worms can be included in cleverly crafted emails to entice a victim to open the attachment. Mail attachments are considered a computer-based social-engineering attack.
