  • Globally uncommon IP address connection from a signed process Informational 3 variations

    A signed process connected to an external IP address that, on a global level, it usually doesn't connect to.

    Activation:
    14 Days
    Training:
    30 Days
    Test:
    N/A (single event)
    Deduplication:
    1 Day
    ATT&CK tactics: Defense Evasion (TA0005) Command and Control (TA0011)
    ATT&CK techniques: System Binary Proxy Execution (T1218) Application Layer Protocol (T1071)
    Required data: XDR Agent
    Detector tags: Global Anomaly Analytics
    Attacker's goals: Attackers may use various methods to execute code in the context of a signed process to avoid detection.
    Investigative actions: Verify the destination IP address reputation. Check whether the actor process loaded a suspicious DLL before the alert. Check if the actor process was injected before the alert. Verify whether the process execution and connections are legitimate.
