Ransomware
What is Ransomware?
Malware that encrypts your files and demands payment for the decryption key. It spreads through phishing emails, malicious downloads, or compromised remote access. Paying doesn't guarantee you'll get your files back — and marks you as a target for repeat attacks.
Why Ransomware Matters
Recovery without a backup is often impossible. Off-site backups plus basic hardening are far cheaper than the alternative. The best defense is preventing the initial breach and having verified, tested backups.

Backup (the 3-2-1 rule)
A copy of your files stored somewhere else, so a dead computer doesn't mean dead data. The 3-2-1 rule: keep 3 copies of your data, on 2 different types of media, with 1 copy stored off-site — so a single fire, flood, or ransomware attack can't destroy everything.
BackupMalware
Any software written to harm you or your business — viruses, spyware, trojans, ransomware, and adware all fall under this word. It can steal passwords, encrypt files, hijack browsers, or use your computer to attack others.
SecurityEncryption
Scrambling data so only someone with the right key can read it — even if it's stolen.
SecurityPhishing
A fake email, text message, or website that impersonates someone you trust — a bank, a coworker, a service provider — to trick you into handing over passwords, clicking harmful links, or sending money. The message looks legitimate but leads to a copycat site designed to steal your credentials.
