If a match is found in the password hash, John the Ripper then displays the password in raw form as the cracked password. It will then match the hashed passwords with the initial hashed password and try to find a match. Now to crack the password, John the Ripper will identify all potential passwords in a hashed format. This bunch of passwords stored together is known as a password dictionary.

It has a bunch of passwords in both raw and hashed format. John the Ripper is a free, open-source password cracking and recovery security auditing tool available for most operating systems. The hashing algorithm converts the raw password into a series of characters (hash) that would take a lot of time and resources to decode. When you enter a password into an account, the password is not saved in a raw format. Having known what Penetration testing is, let’s see what password cracking is:įirst, let’s understand how passwords are stored on your PC or any server. This type of penetration testing is known as social engineering.

The pen tester can try to extract useful information from an employee by asking questions or deceiving the employee. Social Engineering- It is said that the weakest link in any security system is the human being.

Internal Pen Test- This is a type of Pen testing where the attacker tries to gain access to a system by physically accessing the internal resources, implanting a malicious drive, or taking the role of an ill-intended employee that grants remote access to private data. Loopholes like these are identified and sealed before unwanted parties gain access. Vulnerabilities exploited can grant access to the Pentester to remotely gain access to private data. Let’s take a look at some common ways a system’s vulnerability can be exploited.Įxternal Pen Test - This is a type of attack where a pen tester uses publicly available information to try to gain access into a system. Penetration testing can be practiced in different ways. On the other hand, trying to bypass the system’s security without permission is considered illegal and hence known as Red Hat hacking.

This is an attempt to identify the level of a security system by trying to gain access into the system through identified vulnerabilities with permission from authorized personnel. This form of hacking is commonly known as penetration testing, also known as pen test. Well, you might be right.īut, hacking is also an attempt to explore methods of breaching a defense mechanism and exploiting a weakness of a system to prevent unauthorized parties into the system by sealing the loopholes found in the system. From your perspective, you might think that hacking is the act of trying to gain access to certain network servers. Most people often misunderstand the term hacking.
