Execution

T1047 antivm_wmi: Uses WMI to detect virtual environment
T1047 has_wmi: Executes one or several WMI requests

Privilege Escalation

T1134 opens_thread_token: Opens the access token associated with a thread
T1134 opens_process_token: Opens the access token associated with a process

Defense Evasion

T1497.001 antivm_wmi: Uses WMI to detect virtual environment
T1497.003 antisandbox_sleep: The process attempted to slow down analysis
T1497 evasion_printers: Attempts to detect Sandbox by exploring existing printers
T1497 evasion_diskenum: Sandbox evasion using enumeration of partitions
T1497.001 antivm_generic_productname: Checks system product name in registry, possibly for anti-virtualization
T1497.002 antivm_usbstor: Reads information about usbdevices from regkey
T1134 opens_thread_token: Opens the access token associated with a thread
T1134 opens_process_token: Opens the access token associated with a process
T1027.002 packer_entropy: Probably contains compressed or encrypted data

Discovery

T1033 recon_beacon: The process has sent information about the computer over the network
T1083 crawls_directories: Opens a huge number of directories all over disk C: (possibly, searches for sensitive data)
T1497.001 antivm_wmi: Uses WMI to detect virtual environment
T1082 has_wmi: Executes one or several WMI requests
T1518 locates_browser: Attempts to identify where browsers are installed
T1497.003 antisandbox_sleep: The process attempted to slow down analysis
T1016 get_hostname: Attempts to get hostname
T1497 evasion_printers: Attempts to detect Sandbox by exploring existing printers
T1497 evasion_diskenum: Sandbox evasion using enumeration of partitions
T1497.001 antivm_generic_productname: Checks system product name in registry, possibly for anti-virtualization
T1497.002 antivm_usbstor: Reads information about usbdevices from regkey

Command and Control

T1071.001 recon_beacon: The process has sent information about the computer over the network
T1071.001 network_cnc_http: Suspicious HTTP traffic
T1071.001 network_http: Performs HTTP requests

Exfiltration

T1022 encrypts_pc_info: Collects and encrypts information about the computer (possibly for exfiltration)

Impact

T1486 modifies_files: Cryptolocker indicators detected (renamed 500 or more files)
