Hackers are on the prowl. You don’t need to grant them any permission before they invade your system and cause unprecedented harm. So much money has been invested to create a defense mechanism against them. Firewalls have been raised and with each improvement in security, these hackers have come up with a more virulent way to attack and sought out ways to circumvent the system. Most often, the original intent of hackers is to gain access to information or data that ordinarily they should not have access to. Many had been defrauded as a result of hackers having access to their bank accounts. Organizations have crumbled as a result of the nefarious activities of these people. There have been situations when they had gained access to privileged information, encrypted them and requested for a ransom from the victim just to regain access to their own data.
