Deadliest Virus In The World.


WannaCry is a ransomware virus that was first discovered in May 2017. It quickly spread to over 150 countries, causing widespread damage to businesses and individuals. The virus is a type of malware that encrypts the victim's files and demands payment in the form of Bitcoin in exchange for the decryption key.

The WannaCry virus was able to spread so quickly because it exploited a vulnerability in older versions of the Windows operating system. The vulnerability, known as "EternalBlue," was discovered by the National Security Agency (NSA) and was later leaked by a group known as the Shadow Brokers. Once the vulnerability was made public, it was quickly exploited by the WannaCry virus.

WannaCry affected a wide range of organizations, including hospitals, universities, and government agencies. The virus was particularly devastating for the National Health Service (NHS) in the United Kingdom, where it caused widespread disruption to healthcare services. In some cases, hospitals were forced to cancel surgeries and redirect patients to other facilities.

The impact of the WannaCry virus was significant, with estimates of the total cost of the attack reaching into the billions of dollars. In addition to the financial cost, the virus also caused significant disruption to businesses and individuals.

The WannaCry virus serves as a reminder of the importance of keeping software and systems updated. The vulnerability that was exploited by the virus had been patched by Microsoft before the attack, but many organizations had not yet applied the update. It's important for individuals and organizations to regularly apply security updates and patches to their systems in order to protect against known vulnerabilities.

Another important aspect in preventing similar attacks is backing up important data, so that in the event of an attack, the data can be restored. Additionally, it's important to be aware of phishing and social engineering tactics. Ransomware attacks often start with a phishing email that tricks the user into downloading the malware.

In conclusion, the WannaCry virus was a devastating ransomware attack that affected organizations in over 150 countries. It exploited a vulnerability in older versions of the Windows operating system and caused widespread disruption and financial damage. The attack serves as a reminder of the importance of keeping systems and software updated and being aware of phishing and social engineering tactics. Additionally, regularly backing up important data is also crucial in case of an attack.
