This rule monitors for the execution of the ProxyChains utility. ProxyChains is a command-line tool that enables the
|
|
routing of network connections through intermediary proxies, enhancing anonymity and enabling access to restricted
|
|
resources. Attackers can exploit the ProxyChains utility to hide their true source IP address, evade detection, and
|
|
perform malicious activities through a chain of proxy servers, potentially masking their identity and intentions.
