    ATT&CK tactics: Credential Access (TA0006) Discovery (TA0007)
    ATT&CK techniques: Network Sniffing (T1040)
    Required data: XDR Agent with eXtended Threat Hunting (XTH)
    Attacker's goals: Enable access to raw network traffic via promiscuous mode, allowing an attacker to sniff credentials and other sensitive data from the organization's network, and in some cases interfere with network communications.
    Investigative actions: Verify whether the process is expected and recognized by IT or the user. Check whether the driver was installed recently. If it was installed using sc.exe, this may indicate malicious activity. Review who executed sc.exe to validate legitimacy.
