What is Ransomware Wanna Cry?
To understand Ransomware Wanna Crypt, let's first talk about Ransomware.
- Ransomware is a type of malicious software (malware) that encrypts multimedia files, documents, and other files on the target computer. Users can only access these files by agreeing to the attacker's 'ransom.' For more details on Ransomware and its history, readers can check out the article on What is Ransomware introduced by Mytour.
- Wanna Crypt, also known as Wanna Cry, has recently been spreading rapidly. Its propagation is highly dangerous, with 90 countries confirming infections of this Ransomware Wanna Crypt, including Vietnam. Wanna Crypt can infiltrate all computers within the same network system through a vulnerability called Eternal Blue, without users needing to click on any links or attachments. Just one infected computer in the system poses a risk to all.
Furthermore, Wanna Crypt only allows you a few hours to pay the ransom if you don't want to lose all your data. While there are methods to remove WannaCry, they are not comprehensive. Therefore, if you've looked into ways to remove WannaCry from your computer, you've only removed part of it.
