Sykipot
Sykipot is malware referenced in reporting on Chinese cyber operations. In September 2013, Chinese hackers used Sykipot to target entities in the U.S. defense industrial base as well as organizations in telecommunications, computer hardware, government contracting, and aerospace. Reported behavior includes account and privilege discovery using commands such as net group "domain admins" /domain and net localgroup "administrators" to enumerate privileged group membership, remote system discovery using net view /domain to list hostnames of available systems on a network, and service discovery using net start to display running services. Sykipot also uses SSL to encrypt command-and-control communications.

Persistence
"The National Defense University discovered Chinese malware in its computer systems." and repeated references to intrusions involving malware (e.g., Luckycat; Sykipot; malware spread to foreign government websites).
The content repeatedly describes malware and threat actors establishing persistence by adding values under HKCU/HKLM\Software\Microsoft\Windows\CurrentVersion\Run or RunOnce, and by placing executables, scripts, or .lnk files in the Startup folder.

Discovery
"actors used the following command ... to obtain information about services: net start"; "APT1 used the commands net start and tasklist to get a listing of the services on the system"; "OilRig has used sc query on a victim to gather information about services"; "Indrik Spider has used the win32_service WMI class to retrieve a list of services"
The content repeatedly describes malware and threat actors using commands and APIs such as ipconfig /all, ifconfig, arp -a, route print, nbtstat, netsh, GetAdaptersInfo, and GetIpNetTable to gather IP addresses, MAC addresses, DNS, DHCP, gateways, routing tables, ARP cache, proxy settings, domains, and network adapter/interface details.
During the 2015 Ukraine Electric Power Attack, Sandworm Team remotely discovered systems over LAN connections. OT systems were visible from the IT network as well, giving adversaries the ability to discover operational assets.
The content repeatedly describes malware and threat actors obtaining lists of running processes, using utilities such as tasklist, ps, WMI, Get-Process, CreateToolhelp32Snapshot, EnumProcesses, and similar APIs/commands to enumerate active processes on victim systems.
Brute Ratel C4 can use LDAP queries, net group "Domain Admins" /domain and net user /domain for discovery. OilRig has run net group "domain admins" /domain and net group "Exchange Trusted Subsystem" /domain to get account listings on a victim. Wizard Spider has identified domain admins through the use of net group "Domain admins" /DOMAIN.
Multiple actors and tools are described enumerating domain users/admins via Windows net commands (e.g., net user /domain, net group "Domain Admins" /domain), LDAP/AD queries (e.g., Get-ADUser, Get-ADGroupMember), and AD enumeration utilities (e.g., AdFind, BloodHound, AD Explorer).

Command and Control

Command and Control
“Chinese hackers used malware, known as ‘Sykipot’…” / “discovered Chinese malware in its computer systems.” / “used their access to spread malware to foreign government websites.”
The content repeatedly describes malware and threat actors using SSL, TLS, HTTPS, RSA, AES, Blowfish, RC4, ECIES, Diffie-Hellman, OpenSSL, WolfSSL, and mutual TLS to protect command and control traffic.
Multiple malware families and intrusion sets are described as encrypting C2 traffic using SSL/TLS/HTTPS (e.g., "used HTTPS for command and control", "encrypts C2 communications with TLS", "uses SSL for encrypting C2 communications", "TLS-encrypted WebSocket Protocol (WSS) for C2").
