accessible lists of IP addresses published on various online resources. Where Do Public Proxies Come From? Public proxies can come from different sources. First example: An inexperienced server administrator (e.g. an administrator in an educational institution) installs a proxy script for the institution&#8217;s requirements, but does not change the default ports (80, 3128) and does not secure them with a password. In this case the institution&#8217;s server becomes a public proxy. Second example: An Internet user downloads a program that contains a security hole and cannot be updated because the copy protection has been removed (&#8220;cracked software&#8221;) or a Trojan has been installed.
