I received a physical examination text message from a class teacher, and the teacher said it was not sent by him. Is this a scam message?

To be sure, these short messages will let you install a "physical examination report", and the software contains the malicious plug-in "a.privacy.emial.d". The risk is that the background intercepts the short message and forwards it to the designated number, revealing the account number or password in the user's short message. You don't click on the link in the text message; Secondly, with the help of security software such as Tencent Mobile Manager, pseudo base station messages and harassing messages can be identified and intercepted. Even if you accidentally visit the phishing website and install the risk APP, you can remind the risk items, kill the virus, stop the operation in time and avoid property losses through Tencent Mobile Manager.
