  • Digitally distributing child pornography

Cybercrime Attack Types

Hackers

Cybercrime can attack in various ways. Here, is some most common cybercrime attack mode:

Hacking:

It is an act of attaining unauthorised access to a computer system or network.

Denial Of Service Attack:

In computing, a denial-of-service attack is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet.

Software Piracy:

Spoofing:

Spoofing is the act of disguising a communication from an unknown source as being from a known, trusted source It is mostly used to get access to exclusive privileges enjoyed by that network or computer.

Cyber Crime Tools

There are many types of Digital forensic tools

Kali Linux:

It is a specially designed program for digital forensics and penetration testing.

OPhcrack:

Ophcrack is a free open-source program that cracks Windows log-in passwords by using LM hashes through rainbow tables.

EnCase:

This software allows an investigator to image and examine data from hard disks and removable disks.

SafeBack:

SafeBack is mainly using for imaging the hard disks of Intel-based computer systems and restoring these images to some other hard disks.

MD5Sum:

md5sum is a computer program that calculates and verifies 128-bit MD5 hashes.
