jQuery files infect WordPress sites with malware

To make detection more difficult, these malicious files replace legitimate files at ./wp-includes/js/jquery/, where WordPress usually stores jQuery files. So, files jquery-migrate.js and jquery-migrate.min.js contain obfuscated code that additionally loads a strange analytics.js file with malware inside.

It will effect wordpress's core js files as well. 

If your website uses WordPress or popular JavaScript plugins such as jQuery Migrate, it is recommended that you regularly conduct a thorough security audit and check for anomalies that could indicate signs of malicious activity.

To fix issue we need to replace/clean js files and requeast to review in google console.

These issue is not only in wordpress but we are seeing in many core php website also.
