PRC-Nexus REDCap Exploitation (INFINITERED)
This rule detects potential exploitation attempts targeting REDCap, specifically looking for file events involving 'help.php' or 'Upgrade.php', or network events where the remote URL contains 'REDCAP-TOKEN'. These indicators suggest an attacker might be trying to exploit known vulnerabilities or exfiltrate data from a REDCap instance.
