What it detects

This rule detects a Run key persistence entry whose value references a SOCKS5 proxy component or the PerfLogs staging path. SystemBC establishes a SOCKS5 proxy for command-and-control and anchors it via an autorun registry value, combining persistence with proxy-based C2 tunneling.
