Cybersecurity is a critical concern in today’s connected world, and it’s getting more important every day. Knowing when your technology is compromised can save you from significant risks, so let’s look at some key signs to look for and steps to secure your devices.
Unusual performance and unexpected activity
If you notice that your device suddenly slows down or see strange behaviors, like apps opening by themselves, it could be an indication that there is a problem. You may also notice an increase in data usage, unexplained logins to accounts, or unexpected charges on your statements.
Tip: Monitor your device’s task manager to check for unfamiliar processes. Keep a log so you are better able to notice unusual processes.
Unauthorized access to accounts
Hackers often aim to gain access to your accounts or even use your device to hack others to cover their tracks at your expense. Regularly check your email and online accounts for login attempts from unfamiliar locations or devices. Contact your email provider and change your password if you notice any.
Tip: Enable two-factor authentication (2FA) wherever possible.
Alerts from your internet provider or software
Sometimes, your ISP or antivirus software may detect unusual activity and alert you. Please don’t ignore these warnings, as they can signal that your device is part of a larger scheme.
Tip: Always use trusted antivirus software and keep it updated to catch potential threats early.
Tools to stay proactive
Keeping your devices and networks secure requires regular checks to ensure your software and firmware are up to date. Use secure passwords and avoid reusing them across platforms. It may be easier to remember one password, but if a hacker learns it, they will have access to everything. Many online services will help you create and manage passwords, and we even have a simple Python script that will help you here at GeekSided.
It’s also a good idea to monitor your home network for unknown devices that are within the range of your router, even if they aren’t necessarily trying to connect to get familiar with your internet environment.
