Unknown file in WordPress core(Scan)

  • Hi,

    It was an automatic scan of the website using Wordfence.

    I have a few unknown files after upgrading to WordPress 5.4, and it says the following message:
    This file is in a WordPress core location but is not distributed with this version of WordPress. This scan often includes files leftover from a previous WordPress version, but it may also find files added by another plugin, files added by your host, or malicious files added by an attacker

    Files as:
    wp-includes/class-wp-object-cache.php
    wp-includes/css/dist/block-directory/style-rtl.css
    wp-includes/css/dist/block-directory/style.css
    and 9 more like this.

    So, I was suggested by the Wordfence team to open the topic here, as there seems to be an issue with WordPress connection in my website. I’ve added the thread link below so that you guys can get up to speed. ??

    Thanks

    Assume you’ve been hacked and remove then replace the WP core files.

    Get a fresh cup of coffee, take a deep breath and carefully follow this guide. When you’re done, you may want to implement some (if not all) of the recommended security measures.

    If you’re unable to clean your site(s) successfully, there are reputable organizations that can clean your sites for you. Sucuri and Wordfence are a couple.

    Hi @sterndata

    I’m not hacked I can confirm that very well. And as mentioned in the Wordfence support ticket, these files exist in WordPress 5.4 but do not exist in WordPress 5.3.2, so this might indicate that your site is not able to connect to the www.remarpro.com API, as mentioned by @wfphil.

    So, you’re saying that these files are not part of WordPress 5.4? Or is there something else that I’m missing?

    You can see the list of files here: https://github.com/WordPress/WordPress/tree/master/wp-includes

    What does Site Health say about conecting to the wp.org API?

    It says www.remarpro.com is reachable.

    And I checked all the files are there in the directory on Github. So, what now?

    Then that’s not the issue.

    >> nd I checked all the files are there in the directory on Github <<

    I think you need to go back to WordFence and ask them why they’re reporting valid files as incorrect.

    Hi,

    So, if the API is reachable then there’s some issue with Wordfence?

    Those files are part of 5.4, as wpphil mentioned. So, yes, you need to ask them.
