CyberGuard Tips

The single most exploited weakness in home computing is not a clever new hacking technique. It is the "Remind me later" button. Security researchers consistently find that the overwhelming majority of successful attacks use vulnerabilities that were patched months or years earlier — flaws with a fix already sitting on the vendor's server, waiting for someone to click install. Updating is boring, it interrupts your work, and occasionally it breaks something. Here is what is actually happening when you postpone one, how the risk window works, and how to set things up so updates stop being a decision you have to make. What a Security Update Actually Contains Software ships with bugs. Some of those bugs let an attacker do something the developer never intended — read memory they should not see, run code from a file that was supposed to be just data, escalate from a limited account to full administrator. When a researcher finds one, it is assigned a CVE identifier and re...

Ransomware negotiators will tell you the same thing every time: the victims who walk away without paying are not the ones with the best antivirus. They are the ones with a working backup. Everything else in security is about preventing an attack. Backup is the only control that decides how bad it is when prevention fails — and prevention eventually fails for everyone. What the 3-2-1 Rule Actually Means It is the oldest and most reliable backup principle in existence, and it survives because it defeats every common failure mode at once. 3 copies of your data. The original plus two backups. Two copies protect against one failure; three protect against the failure that happens while you are restoring from the second. 2 different types of media. Do not keep both backups on identical drives bought on the same day. Drives from the same batch fail at similar times. Mix an external drive with cloud storage, or an SSD with a network drive. 1 copy offsite. Fire, flood, and ...

One day your computer is fine. The next, every file you own — photos, documents, work files — is locked behind a screen demanding $500 in Bitcoin. This is ransomware, and in 2026, it's more dangerous than ever. Ransomware attacks increased by 73% in 2025 , and cybercriminals are now using AI to make them smarter, faster, and nearly impossible to detect before it's too late. Whether you're an individual user or a small business owner, this guide will show you exactly how ransomware works — and how to stop it. 1. What Exactly Is Ransomware? Ransomware is a type of malicious software (malware) that encrypts your files, making them completely inaccessible. The attackers then demand a ransom — usually in cryptocurrency — in exchange for the decryption key. Think of it like this: imagine someone broke into your home, put every item in a locked safe, and slid a note under the door saying "Pay $1,000 or you'll never see your stuff again." That's exactl...
