WannaCry Ransomware Definition
WannaCry Ransomware is a type of malicious software from cryptovirology that threatens to publish the victim’s data or perpetually block access to it unless a ransom is paid. It specifically targets systems running the Microsoft Windows operating system, encrypting data and demanding ransom payments in the Bitcoin cryptocurrency.
What is WannaCry Ransomware?
WannaCry Ransomware is a cyber threat that is categorized as a cryptoworm.
It is not a typical virus, but a piece of malicious software that encrypts files on a victim’s computer and renders them inaccessible.
The creators of WannaCry then demand a ransom from the victim, payable in Bitcoin, to unlock the files.
Who is behind WannaCry Ransomware?
The exact identity of the creators of WannaCry Ransomware is unknown, but it is believed to be the work of a group called the Lazarus Group.
This group is thought to have ties to North Korea.
However, the North Korean government has denied any involvement in the cyber attack.
When did WannaCry Ransomware occur?
The WannaCry Ransomware attack occurred in May 2017.
It spread rapidly across the globe, affecting organizations and individuals in over 150 countries.
Where did WannaCry Ransomware spread?
WannaCry Ransomware spread worldwide, affecting over 200,000 computers across 150 countries.
It hit many large organizations, including the National Health Service in the UK, telecom companies in Spain, and FedEx in the United States.
Why is WannaCry Ransomware significant?
WannaCry Ransomware is considered one of the most destructive and widespread cyber attacks in history.
It caused massive disruption, particularly in the healthcare sector, and economic losses estimated in the billions of dollars.
The attack highlighted the vulnerability of critical infrastructure to cyber threats and led to increased focus on improving cybersecurity.
How does WannaCry Ransomware work?
WannaCry Ransomware exploits a vulnerability in Microsoft Windows known as EternalBlue, which was initially discovered by the National Security Agency (NSA) in the United States.
Once it infects a computer, the ransomware encrypts the user’s files and displays a message demanding a payment in Bitcoin to decrypt the files.
It also has a worm-like ability to spread to other computers on the same network.
