Ethical Hacking - ARP Poisoning

 Address Resolution Protocol (ARP) is a stateless protocol used for resolving IP addresses to machine MAC addresses. All network devices that need to communicate on the network broadcast ARP queries in the system to find out other machines’ MAC addresses. ARP Poisoning is also known as ARP Spoofing.

Here is how ARP works −

●      When one machine needs to communicate with another, it looks up its ARP table.

●      If the MAC address is not found in the table, the ARP_request is broadcasted over the network.

●      All machines on the network will compare this IP address to MAC address.

●      If one of the machines in the network identifies this address, then it will respond to the ARP_request with its IP and MAC address.

●      The requesting computer will store the address pair in its ARP table and communication will take place.

Hacker

•  A hacker may refer to any of the following: Computer hacker1. A hacker is a term that first started being used in the 1960s and described a programmer or someone who hacked computer code. Later the term evolved into an individual who had an advanced understanding of computers, networking, programming, or hardware, but did not have any malicious intents. In 1981, Ian Murphy, also known as "Captain Zap", became the first hacker to be convicted of hacking. He hacked into the AT&T computer network and modified the billing rates system, changing the internal clocks so that cheaper late-night rates were billed to customers during mid-day hours. Today, a malicious hacker is usually referred to as a malicious user, black hat, or criminal hacker, which describes any individual who illegally breaks into computer systems to damage or steal information. Some people who consider themselves leet may refer to themselves as a leet haxors, h4x0rs, or HaXXorZ. However, often these users...

What constitutes ethical hacking?

  For hacking to be deemed ethical, the hacker must obey the following rules: 1.        Expressed (often written) permission to probe the network and attempt to identify potential security risks. 2.        You respect the individual's or company's privacy. 3.        You close out your work, not leaving anything open for you or someone else to exploit at a later time. 4.        You let the software developer or hardware manufacturer know of any security vulnerabilities you locate in their software or hardware, if not already known by the company. The term "ethical hacker" has received criticism at times from people who say that there is no such thing as an "ethical" hacker. Hacking is hacking, no matter how you look at it and those who do the hacking are commonly referred to as computer criminals or cyber criminals. However, the work that ethical hackers do for org...

Insecure Cryptographic Storage

●  Description Insecure Cryptographic storage is a common vulnerability which exists when the sensitive data is not stored securely. The user credentials, profile information, health details, credit card information, etc. come under sensitive data information on a website. This data will be stored on the application database. When this data are stored improperly by not using encryption or hashing*, it will be vulnerable to the attackers. (*Hashing is transformation of the string characters into shorter strings of fixed length or a key. To decrypt the string, the algorithm used to form the key should be available) Implication ·          By using this vulnerability, an attacker can steal, modify such weakly protected data to conduct identity theft, credit card fraud or other crimes. Vulnerable objects ·          Application database. Examples In one of the banking application, password database uses unsal...
