Ransomware – The Facts
Ransomware is a piece of malicious software that encrypts users data and demands payment in return for the decryption key. It is able to evade detection by normal anti-virus products and for this reason is a real threat to your business.
How does the infection take place?
- An e-mail is received by the user, which contains a malicious link or an attachment. The infection may also originate from a malicious website.
- When the link is followed or the attachment is opened, a downloader is placed on the users system.
- The downloader then downloads the ransomware program on the system.
- The ransomware starts to encrypt the entire hard disk content. If a network drive is mapped to the computer it will also encrypt this also.
- A warning similar to the one below is displayed on the screen with instructions on how to pay for the decryption key.
