Ethical Hacking - DNS Poisoning

 DNS Poisoning is a technique that tricks a DNS server into believing that it has received authentic information when, in reality, it has not. It results in the substitution of false IP address at the DNS level where web addresses are converted into numeric IP addresses. It allows an attacker to replace IP address entries for a target site on a given DNS server with IP address of the server controls. An attacker can create fake DNS entries for the server which may contain malicious content with the same name.

For instance, a user types www.google.com, but the user is sent to another fraud site instead of being directed to Google’s servers. As we understand, DNS poisoning is used to redirect the users to fake pages which are managed by the attackers.

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...
