The recent Sony hacking incident has many of us worried about our own computer vulnerabilities. This whole episode started as a ransomware attack and when they wouldn’t pay up, the criminals unleashed their fury, not by deleting all of their computer files as is the common assault, but by publishing embarrassing information and threatening harm to customers. And it’s not just global billion dollar industries at risk here, hackers are invading small businesses and everyday people by hijacking Facebook pages, Twitter accounts, online bank information and files.
Small businesses often do not have the luxury of employing an IT specialist or a security team. That’s why it’s important to ensure your computer, the hub of your business operations, is secure from hackers.
The best defense is a good offense.
Here are some offensive strategy musts:
- Invest in a comprehensive anti-virus, anti-malware and computer security software. I like Bitdefender, but there are many good ones. Read reviews.
- Keep your systems updated. Windows, OS, Java, etc. should be set for auto-updates, many of which are related to security.
- Don’t click email links from unknown senders. Use caution with messages containing links from UPS, Fedex and other delivery services about packages, particularly if you are not expecting a delivery. The delivery information almost always goes to the sender, not the recipient.
- Stay away from popup ads on websites. Go to websites direct, not via questionable popups.
- Use your firewall. It will block some things before you even know about them.
- Back up your computer files in a separate drive or with an off-site storage or cloud system. I use Carbonite because of its affordability and ease. There are others.
Should you find yourself victim to a hacker, act quickly. A social media hijack is an easy fix because they have easy steps to follow. Click their “help” button and search for “hacked account.” If your files are being ransomed, here is a suggested defensive strategy:
- Get advice from a computer service center, if they can handle it in a timely manner.
- Check out websites from one or both of these computer security companies. They have instructions and experts to guide you through the steps to remove the virus and retrieve your files without paying a ransom: bleepingcomputer.com, FireEye and Fox-It (CrytoLocker ransomware only).
- Call Microsoft (read their suggestions here) or Apple (yes Macs are being hacked too).
- Think twice before you pay a ransom. Many people pay and their files are not returned.
Be safe.
