  • Manipulation of service imagepath configuration Informational Persistence

    This key specifies the location of the executable file for the driver or service. Malicious executables might be installed in these paths.

    Indicator:

    Registry action type = create_registry_key , set_registry_value AND registry key name = *\services\*\imagepath Host host os = windows

    ATT&CK tactics: Persistence (TA0003)

  • Modification of systemd service files Informational Persistence

    An attacker may create or modify systemd service unit files to establish persistence between reboots.

    Indicator:

    File action type = write , create AND file path =~ (^/etc/systemd/system/|^/usr/lib/systemd/system/|^/run/systemd/system/|/lib/systemd/system/|\.config/systemd/user/|^/etc/systemd/user/|\.local/share/systemd/user/|^/run/systemd/user/|^/usr/lib/systemd/user/).*\.service Host host os = linux

  • Multiple RDP sessions enabled via Registry Medium Persistence

    Attackers may allow multiple RDP sessions, so they could access the machine at the same time the user does.

    Indicator:

    Registry registry key name = HKEY_LOCAL_MACHINE\SYSTEM\*ControlSet*\Control\Terminal Server AND registry value name = fSingleSessionsPerUser AND action type = set_registry_value Host host os = windows

  • New service created via command line Informational Persistence

    Attackers may leverage services to gain persistence on an endpoint.

    Indicator:

    Process action type = execution AND target process cmd = *create*binpath* AND target process name = sc.exe

  • Persistence through service registration Informational Persistence

    An attacker may add or modify system services to persist on a host.

    Indicator:

    File action type = write , create , rename AND file path =~ /etc/(init.d/|rc|systemd|inetd.conf|modules|modprobe.conf|inittab).*|/lib/systemd.* Host host os = linux

  • PowerShell creates a new service Low Persistence

    PowerShell creates a new service via a command line. This can be used by attackers to be persistent on a machine.

    Indicator:

    Process action type = execution AND target process cmd = *New-Service* AND target process name = powershell.exe
