With the popularity of mobile payment and finance applications, our cell phones are facing greater security risks, which can cause serious property loss if they are implanted with Trojan horses or encounter sniffing attacks. The external links present in spam messages (Figure 1) are the invasion channel for most of the risks, so the first thing we need to do is to prevent stepping into the deadly trap by mistakenly clicking it.
External links in SMS messages can lead to web pages with Trojan horses or fake websites of Taobao or carriers, making it impossible to protect against them. The good news is that many new phones now have SMS fraud prevention features integrated into the SMS app, and all we have to do is find and turn them on.
Take Huawei/Glory cell phone as an example, in the SMS interface, click the three dots icon in the upper right corner to enter the settings, you can see the “Malicious URL identification” option (Figure 2), its effect is to automatically network to identify the authenticity and security of external links in SMS, if there is a risk when you click on it will pop up a warning prompt. The OPPO phone can enter “Settings → System Applications → Information”, where you can also see the “malicious URL identification” function (Figure 3), can be turned on and off at any time.
Tip similar settings entrance and name may differ between different brands of cell phones, so you can be patient and look for it.
