Identifying whether you've been hacked often comes down to recognizing unusual or unexpected behavior on your devices or online accounts. While some signs are blatant, others can be subtle indicators of a compromise.
Common Signs of a Hacked Device or Account
A hack can manifest in various ways, from overt messages demanding payment to subtle changes in your browser's behavior. Here are the key indicators that suggest your system or online accounts may have been compromised:
- Ransomware Messages: One of the most direct signs is seeing a message on your screen demanding payment (often in cryptocurrency) to unlock your files or regain access to your computer. This indicates your system has been encrypted by ransomware.
- Fake Antivirus Alerts: You might encounter persistent pop-up warnings or messages from an antivirus program you don't recognize or didn't install. These fake alerts typically claim your computer is heavily infected and urge you to pay for a "full version" or "fix" to remove non-existent threats.
- Unwanted Browser Toolbars: Your web browser may suddenly display new toolbars, extensions, or add-ons that you didn't intentionally install. These often come bundled with other software and can alter your browsing experience.
- Redirected Internet Searches: When you try to search for something online, your browser might automatically redirect you to a different search engine or a malicious website, even if you typed in a legitimate URL. This is a classic sign of browser hijacking.
- Frequent, Random Popups: Experiencing an unusual increase in pop-up advertisements, especially when you're not actively browsing the web or when they appear in unexpected places, can indicate adware infection. These pop-ups are often irrelevant and disruptive.
- Unsent Social Media Invitations or Messages: Your friends or contacts might inform you that they've received invitations to connect, messages, or posts from your social media accounts that you never sent. This suggests your social media account has been compromised and is being used to spread spam or malware.
- Online Password Isn't Working: If you suddenly find yourself unable to log into an online account (like email, banking, or social media) and you're certain you're using the correct password, it's a strong indicator that a hacker has gained access and changed your password.
