: Be cautious if you find this file unexpectedly on your system. It is sometimes bundled with "cracked" software or malware to help the malicious program communicate back to its "command and control" server while bypassing local firewalls.

: While proxy_prem.txt is a static list, it can sometimes be used to feed more complex PAC files which dynamically decide when to use a proxy based on the URL being visited. Safety & Security Considerations

: Using proxies from an unverified proxy_prem.txt list can be dangerous, as the proxy provider can potentially monitor all unencrypted traffic passing through their server.
