Ransomware definition: What is ransomware?
Ransomware is a type of malware that encrypts a user’s files and demands a ransom be paid to the attacker to decrypt the files.
Ransomware attacks are increasingly common, and they can be devastating for businesses and individuals who are targeted.
There are many different types of ransomware, and new variants are constantly being developed. It is important to be aware of the threat of ransomware and to take steps to protect your data.
How does ransomware work?
Ransomware typically spreads through email attachments or by visiting infected websites.
Once a computer is infected, the ransomware will encrypt files on the hard drive and any connected devices. The cyber criminal will then demand a ransom, usually in the form of cryptocurrency, to decrypt the files.
Paying the ransom does not guarantee that the files will be decrypted, as the attacker might not provide the key.
How to prevent ransomware
There is no guaranteed way to prevent ransomware. However, there are steps organizations can take to reduce the risk of getting infected.
1) Back up data regularly
Regular data backups provide a way to restore files that have been encrypted by ransomware without having to pay the ransom.
2) Keep systems and software up to date
Patching vulnerabilities makes it much harder for attackers to exploit them.

3) Train employees on ransomware
Teach staff how to identify phishing emails, not to click links or open attachments in suspicious emails, and how to report suspicious emails to their IT department.
