5 dumb tech security mistakes you're making

You might think you have a solid cybersecurity plan. You use strong passwords and defensive measures like VPNs and firewalls. But even the strongest shield gets dented from time to time.

It is hard to remember all the settings you have adjusted and the passwords you have made over the years. Let this be your reminder to go in and make a few quick changes to protect yourself.


1. Using the same PIN for your phone lock screen as your bank

You do not want to remember a bunch of codes. They are easy to forget, so you keep it simple and reuse the same PIN.

Do not give in to temptation! It could lead you to financial ruin. Say you are relaxing in the coffee shop, and you open your phone. Someone standing behind you could notice your code, write it down and start using it to access your bank account within minutes.

To protect yourself, use different PINs. If you are struggling to remember them all, consider a password manager.

2. You keep Bluetooth on 24/7

Bluetooth is a short-range wireless radio technology that works similarly to Wi-Fi and cellular networks but performs simpler tasks at shorter ranges. You do not need a cellular signal or network connection to use Bluetooth, and it does not use data.

As with a Wi-Fi network or other connection, Bluetooth has vulnerabilities. Hackers and scammers must be close to you to use Bluetooth to hijack your phone — but in just about any public space, you are arm's length from strangers.

There are a couple of ways to disable Bluetooth on your iPhone. Go to Settings > Bluetooth and switch it off. You can also swipe down from the top right of your screen to open the Control Center and tap the Bluetooth icon.

The same steps work for Android phones: Go to Settings > Connected Devices > Connection Preferences > Bluetooth and switch it off. (Note: Steps vary based on your phone's model. Look or search for Bluetooth if these steps do not match your phone.)

3. Leaving your Wi-Fi network or router unprotected

Few things make a cybercriminal drool more than an unsecured Wi-Fi connection. If they feel particularly nefarious, they can use your network to attack your gadgets. How about stealing your personal information?

They could even download dangerous files or visit illegal websites through your router.

4. You hit unsubscribe on spam

With reputable companies, clicking unsubscribe should do the trick. If you are receiving newsletters or promotional emails from brands you know, they generally follow email marketing regulations. Go ahead and hit that unsubscribe button.

For unsolicited spam from unknown senders? Clicking unsubscribe may indeed make things worse. You inadvertently confirm that your email address is active  possibly leading to even more spam. If it is a random email about a long-lost prince or a miracle cure, steer clear of the unsubscribe link. Mark the email as spam in your email client.

5. You click ads and download files from random sites

This is an easy way to hurt your computer. If you see an item you like in an ad, it is best not to click it. You are better off heading to your search bar and visiting the brand website. There, search for the item in the ad.

Sure, it requires a few extra steps, but it is better to be safe than sorry. After all, it is super easy for cybercriminals to create malicious ads. They might even masquerade as authentic companies to get your guard down.

That is why you should not click on ads, even if they look safe and legitimate. Instead, find the source yourself.
