I don't WannaCry.

Ransom as defined in the dictionary is a sum of money demanded or paid for the release of a captive. These days such ransom are only seen in the typical daily soaps aka Saas-Bahu serials.

Okey, since we have heard of the ransomware attacks in the news recently. We need to know what is this new form of ransom. A ransomware is a computer virus which encrypts the files on victims computer making them inaccessible until the sum of money is paid.

These attacks are typically carried out by a form of computer virus known as trojan horse or trojan for short. A trojan is legitimate file in disguise which the victim finds unsuspicious and downloads them. Attacker can use a trojan as backdoor to have unauthorized control of the victims computer. Trojan carries the payload which encrypts, manipulates or deletes the HDD contents or the master records.

Ransomwares are not new in the market, they have been around and gained popularity in last 15 years. In fact it was first presented in 1996 in the IEEE conference.

The latest one is WannaCrypt which has infected over 10,000 computers around the world just in 2 days. Interestingly the core of WannaCry ransomwhare is ETERNALBLUE a toolkit developed for the same purpose by NSA which was stolen and later got spread. 

WannaCry came to a halt when darienhuss registered a domain which he found that the virus was trying to reach.
