How does a computer or mobile phone virus spread by scanning a QR code?

The virus link is hidden in the QR code map, and the user's mobile phone will jump out of the installation software after "scanning". After installation, the virus will automatically run in the background, and at the same time automatically intercept the SMS and forward it to the virus producer's mobile phone, so that even if your bank card or Alipay is bound to the mobile phone, the virus producer can still transfer all your funds through the intercepted SMS.

An important feature of QR code virus is that it will automatically connect to the designated website or download malicious applications after scanning, so you must pay attention to the results returned after scanning with your mobile phone. For example, it is obviously a WeChat QR code, but after scanning, the software download and installation interface is called up. This is to pay attention to close the installation window in time to avoid bringing opportunities for virus invasion.

Two-dimensional code is also called two-dimensional bar code, and the common two-dimensional code is QR code, which is a coding method. Compared with the traditional bar code, it can store more information and represent more data types.
