RATANKBA is a malware family associated in the provided content with Lazarus Group. It has been delivered to victims via a compromised legitimate website. The malware performs host and network reconnaissance on Windows systems, including querying the Registry key HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\InternetSettings, executing whoami and query user for user discovery, running net user for account discovery, using net view /domain and net view for remote system discovery, and using tasklist /svc to enumerate running tasks/services. The content also states that RATANKBA uses WMI for process monitoring and cmd.exe to execute commands. A variant exists that uses a PowerShell script instead of the traditional PE form. Additional behavior mentioned in the supporting content includes use of netstat -ano to search for specific IP address ranges. High-confidence indicators and artifacts directly referenced include the Registry path HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\InternetSettings and command lines such as whoami, query user, net user, net view /domain, net view, tasklist /svc, cmd.exe, and netstat -ano.

Lazarus Group delivered RATANKBA and other malicious code to victims via a compromised legitimate website.
17 distinct techniques documented for this family, organized by ATT&CK tactic.
The content repeatedly describes threat actors and malware using WMI/WMIC/wmiexec for remote execution, lateral movement, discovery, persistence, and administrative actions; e.g., 'APT41 used WMI in several ways, including for execution of commands via WMIEXEC as well as for persistence via PowerSploit' and 'Scattered Spider used Windows Management Instrumentation (WMI) to move laterally via Impacket.'
The content repeatedly describes threat actors and malware using PowerShell scripts/commands for execution, download, staging, reconnaissance, persistence, credential access, lateral movement, and defense evasion; e.g., "Sandworm Team used PowerShell scripts to run a credential harvesting tool in memory to evade defenses."
"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 querying, enumerating, opening, and reading Windows Registry keys and values, e.g., "APT41 queried registry values to determine items such as configured RDP ports and network configurations" and "Reg may be used to gather details from the Windows Registry of a local or remote system at the command-line interface."
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 collecting usernames, identifying logged-in users, running whoami/query user/quser, checking whether the current user is an administrator, enumerating user sessions, and gathering account details from compromised hosts.
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.
The content is a long ATT&CK-style listing of malware and threat actors that collect host details such as OS version, hostname, architecture, CPU, memory, BIOS, language, and other basic system characteristics; examples include use of commands like systeminfo, ver, uname, sw_vers, and WMI queries.
“actors used the following commands… to enumerate user accounts: net user >> %temp%\download; net user /domain >> %temp%\download … APT1 used the commands net localgroup, net user, and net group to find accounts… APT32 enumerated administrative users using the commands net localgroup administrators … OilRig has run net user, net user /domain, net group "domain admins" /domain …”
