Ransomware is a type of malware that makes your data such as documents and photos unavailable. Usually by scrambling (encrypting) the data so it is unusable. Then, offering to unscramble the data if you pay the ransom. Data recovery is not guaranteed after paying ransom.
Ransomware is usually spread as an email attachment or link to malicious program sent by email that appears to be legitimate organisation or from downloading free apps and games from illegal websites. Upon clicking on the attachment or the link, the malware begins scrambling the data and shows a ransom message upon completion.

I’m suspicious about an email, what other clues to look for?

- The sending address doesn’t look like a legitimate business (e.g. firstname.lastname@example.org) or contains foreign language as a sending email address
- The subject line sounds odd, or includes strange punctuation
- Vague information, not referring to a specific account or product
- Poor grammar
- When hovering over links, they don’t point to the legitimate domain for the business e.g. www.anz.freewebs.com (check the official domains of sites you have accounts with)
- Never click links in emails, always type the website address into your browser
- Try googling the address or name of the person in the email, if the top results are security discussion/sites, you will want to research further
