That functionality is coded not by WP engineers but by computer engineers that have studied the WP code.  Can WordPress Plugins Contain Viruses? Important Questions  How Vulnerable Are Plugins To Viruses?

However, in a well-regulated community like the WP community, it is seldom that plugins have virus issues.  What Should I Do To Protect Myself?

Have A Secure Password    Donu2019t use anything that resembles an actual word, use numbers, and special characters and overall just be smart about your passwords.
