15. T1016 System Network Configuration Discovery Discovery

    What they do: Play has used the information-stealing tool Grixba to enumerate network information.

    What that means: Adversaries may look for details about the network configuration and settings, such as IP and/or MAC addresses, of systems they access or through information discovery of remote systems.

16. T1018 Remote System Discovery Discovery

    What they do: Play has used tools such as AdFind, Nltest, and BloodHound to enumerate shares and hostnames on compromised networks.

    What that means: Adversaries may attempt to get a listing of other systems by IP address, hostname, or other logical identifier on a network that may be used for Lateral Movement from the current system.

17. T1057 Process Discovery Discovery

    What they do: Play has used the information stealer Grixba to check for a list of security processes.

    What that means: Adversaries may attempt to get information about running processes on a system.

18. T1082 System Information Discovery Discovery

    What they do: Play has leveraged tools to enumerate system information.

    What that means: An adversary may attempt to get detailed information about the operating system and hardware, including version, patches, hotfixes, service packs, and architecture.

19. T1083 File and Directory Discovery Discovery

    What they do: Play has used the Grixba information stealer to list security files and processes.

    What that means: Adversaries may steal data by exfiltrating it over a different protocol than that of the existing command and control channel.

26. T1486 Data Encrypted for Impact Impact

    What they do: Playcrypt encrypts files on targeted hosts with an AES-RSA hybrid encryption, encrypting every other file portion of 0x100000 bytes.

    What that means: Adversaries may encrypt data on target systems or on large numbers of systems in a network to interrupt availability to system and network resources.

27. T1490 Inhibit System Recovery Impact

    What they do: Playcrypt can use AlphaVSS to delete shadow copies.

    What that means: Adversaries may delete or remove built-in data and turn off services designed to aid in the recovery of a corrupted system to prevent recovery.

Software Play has been seen using, grouped by what it is used for. Legitimate administration tools appear here because these actors routinely abuse them — presence in this list is not itself malicious.
