What Is WiFi Siphoning And How Does It Happen?
WiFi siphoning, also known as WiFi hijacking or WiFi theft, occurs when someone uses your WiFi network without your permission. This can happen when a neighbor or someone nearby discovers your WiFi network’s name (SSID) and password, either by guessing it or using specialized software to crack the password.
WiFi siphoning can also occur when a device is connected to your network without your knowledge, such as when a guest connects to your network and forgets to disconnect, or when a device is infected with malware that allows hackers to access your network. In some cases, WiFi siphoning can be intentional, such as when someone sets up a rogue access point to intercept your internet traffic.
How Can I Tell If Someone Is Siphoning Off My WiFi?
If someone is siphoning off your WiFi, you may notice a decrease in your internet speed, as the additional devices connected to your network consume bandwidth. You may also notice strange devices connected to your network when you check your router’s device list. Additionally, you may receive notifications from your internet service provider about unusual activity on your account.
Another way to detect WiFi siphoning is to check your router’s logs for suspicious activity, such as unfamiliar devices connecting to your network at odd hours. You can also use network scanning software to detect devices connected to your network and identify any unknown devices.
What Are The Risks Of WiFi Siphoning?
WiFi siphoning can pose several risks to your internet security and personal data. When someone is connected to your network, they can potentially access your personal files, intercept your internet traffic, and steal sensitive information such as passwords and credit card numbers.
Additionally, if someone is using your WiFi network for malicious activities, such as downloading copyrighted content or engaging in cybercrime, you may be held liable for their actions.
