Reverse shell from powershell.exe following Remote Mouse port 1313 exploitation
This rule detects a sequence of events where a host initiates a network connection on port 1313 (a common port associated with certain web-based C2 or exploitation frameworks) followed shortly by an outbound network connection initiated by PowerShell within a 5-minute window. This behavior is indicative of a post-exploitation phase where an initial entry point leverages a malicious script or shell to establish persistent communication.
