Can text messages be intercepted over WiFi?
Text messages can be intercepted over WiFi under certain circumstances. When you send a text message over WiFi, it is transmitted through the internet rather than through your cellular network. This means that anyone with access to the WiFi network or the internet connection can potentially intercept your text messages.
However, it’s worth noting that intercepting text messages over WiFi is not a straightforward process. It requires a certain level of technical expertise and specialized software. Additionally, many messaging apps and services use end-to-end encryption, which makes it difficult for interceptors to read the contents of the messages.
How do hackers intercept text messages over WiFi?
Hackers can intercept text messages over WiFi by using various techniques such as packet sniffing, man-in-the-middle (MITM) attacks, and exploiting vulnerabilities in the WiFi network or the messaging app. Packet sniffing involves capturing and analyzing the data packets transmitted over the WiFi network, while MITM attacks involve intercepting the communication between the sender and the receiver.
To intercept text messages, hackers may also use specialized software such as Wireshark or tcpdump to capture and analyze the data packets. They may also use malware or viruses to infect the sender’s or receiver’s device and gain access to the text messages.
Can you intercept text messages on a public WiFi network?
Yes, it is possible to intercept text messages on a public WiFi network. Public WiFi networks are often unsecured, which makes it easier for hackers to intercept data transmitted over the network. When you send a text message over a public WiFi network, it is transmitted through the network and can be intercepted by anyone with access to the network.
However, many messaging apps and services use end-to-end encryption, which makes it difficult for interceptors to read the contents of the messages.
