May 12th 2017 saw the biggest ever cyber-attack in Internet history. A ransomware named WannaCry stormed through the web. Write an essay on ransomware cyber attack and the measures one can take to protect himself.

Malicious software known as ransomware is created to prevent users from accessing any computer system and holds the owner of the system hostage until the desired ransom is paid. Ransomware frequently enters a computer through open security flaws as a Trojan horse or computer worm. Over 150 nations were impacted by the crypto-ransomware known as WannaCry or WannaCrypt, including India. Major companies and organisations like FedEx, Renault, and the British National Health Service have already been impacted.
A Japanese electronics maker Hitachi, a prominent Korean theatren chain and Chinese government reported that their systems had been affected. Chinese state media reported that 40,000 businesses and institutions have been hit. And that's mere a measure of the electronic consequences of WannaCry. Health care providers in Britain, were forced to turn ambulances away and cancel or delay cancer treatments for patients over the weekend. Ransomware encrypts most of the user files on a Windows PC with virtually unbreakable encryption. The user is informed via a message on the computer screen that he must pay a ransom in the virtual currency Bitcoin. The user may see how much time is left before the ransom is doubled thanks to two countdown clocks on the screen.
Antivirus software helps keep Windows or our PC updated with the most recent security improvements, preventing malware from infiltrating our device. Avoid clicking links in suspicious emails, and only download files from reliable sources. And whenever something unlikely happens our data backup can save us, so store your data somewhere else too, it can be stored in any secondary media storage like a physical hard drive. The banks should update the Microsoft patch as this would help India‘s banking system to insulate against potential threats.
