Ransomware can spread on a network through malicious emails, malicious websites, and through malicious software. Malicious emails may contain malicious links or attachments, or may simply imitate legitimate emails in order to trick users into downloading malware. Malicious websites may download malicious code onto vulnerable computers, while malicious software may be installed on systems accidentally or intentionally by users. Additionally, ransomware may spread across networks through compromised accounts, unpatched remote desktop connections, and insecure file shares.
