TP Link Router Hacking : Demo

Image
TP Link Archer C5 Router Hacking  0 Today we got our hands on a brand new TP Link Archer C5 router which we will be testing for known vulnerabilities such as hidden backdoors and vulnerabilities, brute force default passwords and WPS vulnerabilities. In this new WiFi hacking tutorial we will be using different tools on Kali Linux 2.0 like Reaver, pixiewps and the Aircrack-ng suite to exploit possible vulnerabilities. TP Link is known to use easy to break default passwords such as the WPS PIN as default wireless password or a password which is derived directly from the MAC address. Especially the last one would make it very easy to retrieve the password because the MAC address is not meant to be secret and is actually send with every single wireless packet send from the router. With a packet analyser like Wireshark it is very easy to retrieve MAC addresses from sending and receiving devices, including the router. In this tutorial we’ll be using airodump-ng for this pur...

Hacking and Securing Wing FTP Server 4.3.8

Hacking and Securing Wing FTP Server 4.3.8 In this tutorial we will be looking at how to exploit an authenticated command execution vulnerability in Wing FTP Server 4.3.8 and how to fix this security issue. Authenticated command execution vulnerabilities allow an authenticated attacker to execute arbitrary commands on the target system. In this situation the vulnerability is still ‘protected’ by an authentication layer because the vulnerability resides in the administrator panel. Unauthenticated command execution vulnerabilities are way more dangerous as they reside in publicly accessible places and can be exploited by anyone without authentication. Before we are going to analyse and exploit this vulnerability we will first have a look at Wing FTP Server in general and its extensive list of features. Wing FTP server Wing FTP server is multi-protocol enterprise grade file server with a lot of features that runs on multiple platforms such as Windows, Linux, Mac ...

TCS CodeVita 2016 Round1 Question: Consecutive Prime Sum

Image
Problem : Consecutive Prime Sum Some prime numbers can be expressed as Sum of other consecutive prime numbers. For example 5 = 2 + 3 17 = 2 + 3 + 5 + 7 41 = 2 + 3 + 5 + 7 + 11 + 13 Your task is to find out how many prime numbers which satisfy this property are present in the range 3 to N subject to a constraint that summation should always start with number 2. Write code to find out number of prime numbers that satisfy the above mentioned property in a given range. Input Format: First line contains a number N Output Format: Print the total number of all such prime numbers which are less than or equal to N. Constraints: 1. 2 Sample Input and Output SNo. Input Output Comment 1 20 2 (Below 20, there are 2 such numbers: 5 and 17). 5=2+3 17=2+3+5+7 2 15 1 Pseudo Code: 1. Find all the prime numbers till N     i.  A  is an array length N + 1 initialized with numbers from 0 to N                 ...

TCS CodeVita 2016 Round1 Question: Logic Pyramid

Image
Problem : Logic Pyramid Identify the logic behind the series 6 28 66 120 190 276.... The numbers in the series should be used to create a Pyramid. The base of the Pyramid will be the widest and will start converging towards the top where there will only be one element. Each successive layer will have one number less than that on the layer below it. The width of the Pyramid is specified by an input parameter N. In other words there will be N numbers on the bottom layer of the pyramid. The Pyramid construction rules are as follows 1.      First number in the series should be at the top of the Pyramid 2.      Last N number of the series should be on the bottom-most layer of the Pyramid, with N th  number being the right-most number of this layer. 3.      Numbers less than 5-digits must be padded with zeroes to maintain the sanctity of a Pyramid when printed. Have a look at the examples below to get a pict...
