- Phishing emails: A ransomware attachment can be included in phishing emails that are designed to trick you into opening them. Phishing emails often look like they are from a legitimate source, such as a bank or government agency. Understand more about how phishing works from this source.
- Infected websites: Ransomware can also be downloaded from infected websites. When you visit an infected website, a malicious script can be launched on your computer without your knowledge.
