Most NFC communications do not include encryption mechanisms during its data exchange, it relies on the short range (i.e., less than 4 cm) to guarantee absence of eavesdropping attacks. However, the

The Term Hacker.

the term “hacker” has evolved quite dramatically over the years as the public’s awareness of technology has increased and as a sensationalist mass media continues to color the public’s opinion of hackers. In the beginning, a hacker was someone who worked passionately for the sake of curiosity and exploration.

Reverse Engineering - Playing with gdb

Playing a very basic level of a known wargame the other day I was trying to solve the following problem: Given an executable (ELF, Linux) which accepts a password as an argument and verifies if this is correct, find this string. As most of the problems, it’s quite easy if
