Virus in the extension or on the server?

Question

Google Chrome

Hey!
I have a chrome browser extension. Before the last update, everything was fine, but now some pages that my plugin interacts with have ads. I checked my JS files - everything is clean, and it couldn't be superfluous, I use git. it would be immediately obvious. moreover, I have the plugin installed from a folder, since I often write updates, and other users from the Google store.
I dug into the recorded har file and saw that advertising garbage is added when there is a request to the server (not mine, but the target site for the plugin) to unload the next js that is used on the page, and the response is 307 "Temporary Redirect" status and the Location is transmitted link to js itself with ads.

Here is the question - is it the server or my plugin? where does it come from in my plugin? how can i check exactly? and I requested this JS through postman 100 times and nothing, everything is fine.

Answer 1

beautifully twisted but confused himself
on the subject - if you are the author of the plugin, then on the server, not you - in the plugin
