Description

Downloading a WP installation from a plesk server using no encryption (insecure) resulted in several of its core and plugin files downloaded with what I assume is some sort of binary/invalid data in them along plain text. Samples of the affected files include .CSS and .PHP files.

Attempting to copy the contents (copy-paste) results in truncated data up to the point of corruption.

There were no errors or warnings displayed on the log area during download.

Damage occurred during download and corrupted data was uploaded 'successfully' in that is seems to match the corrupted data.

A second attempt to download the same WP installation resulted in errors on the same files but damaged data occurred at different locations.

The sample files:

/blog/wp-content/plugins/amazon-s3-and-cloudfront/vendor/Aws3/aws-autoloader.php
/blog/wp-includes/css/dashicons.css

Using a different software (phpStorm + Explicit FTPS + Passive) to transfer the files did not result in corruption.

Looks like a rogue network component modified the traffic. Please use FTP over TLS to detect such modification.
