WannaCry ransomware has launched an attack in over 150 countries, impacting over 10,000 organizations such as health ministries, banks and telecommunication companies and 200,000 individuals. PCs/servers without Cloud Backup will have difficulties retrieving data when an attack strikes.
What is WannaCry and how does it work?
Some individuals found their PCs affected with the notorious ransomware this Monday. The virus takes control and tries to encrypt users’ “FILES”. Once successful, it will request you to make payment to get back your files (decrypt). Ransomware blocks your data access until a ransom is paid – it was combined with a worm inside application, a program that is able to replicate and spread to other computers. According to some Security Experts, there will be another attack to come. So make sure your PCs are ready with the most updated patch files and your security is up to date.
How WannaCry Ransomware gets onto a computer
The most common ways in which Ransomware Trojans are installed are:
- Via phishing emails
- As a result of visiting a website that contains a malicious program
After the Trojan has been installed, it will either encrypt information that’s stored on the victim’s computer or block the computer from running normally – while also leaving a ransom message that demands the payment of a fee, in order to decrypt the files or restore the system. In most cases, the ransom message will appear when the user restarts their computer after the infection has taken effect.
What has Microsoft done?
As many corporations are still using the old operating systems, such as Windows XP, Microsoft has decided to take action, and announced a new patch to block the new ransomware. It’s called ‘WannaCrypt Window XP Patch’.
