Summary

Description

This Malware Analysis Report (MAR) is the result of analytic efforts between Department of Homeland Security (DHS), the Federal Bureau of Investigation (FBI), and the Department of Defense (DoD). Working with U.S. Government partners, DHS, FBI, and DoD identified Trojan malware variants used by the North Korean government. This malware variant has been identified as HOPLIGHT. The U.S. Government refers to malicious cyber activity by the North Korean government as HIDDEN COBRA. For more information on HIDDEN COBRA activity, visit https[:]//www[.]us-cert.gov/hiddencobra.

DHS, FBI, and DoD are distributing this MAR to enable network defense and reduce exposure to North Korean government malicious cyber activity.

This MAR includes malware descriptions related to HIDDEN COBRA, suggested response actions and recommended mitigation techniques. Users or administrators should flag activity associated with the malware and report the activity to the Cybersecurity and Infrastructure Security Agency (CISA) or the FBI Cyber Watch (CyWatch), and give the activity the highest priority for enhanced mitigation.

This report provides analysis of twenty malicious executable files. Sixteen of these files are proxy applications that mask traffic between the malware and the remote operators. The proxies have the ability to generate fake TLS handshake sessions using valid public SSL certificates, disguising network connections with remote malicious actors. One file contains a public SSL certificate and the payload of the file appears to be encoded with a password or key. The remaining file does not contain any of the public SSL certificates, but attempts outbound connections and drops four files. The dropped files primarily contain IP addresses and SSL certificates.

Description

This artifact is a malicious 32-bit Windows executable. When executed the malware will collect system information about the victim machine including OS Version, Volume Information, and System Time, as well as enumerate the system drives and partitions.

The malware is capable of the following functions:

---Begin Malware Capability---

Read, Write, and Move Files
Enumerate System Drives
Create and Terminate Processes
Inject into Running Processes
Create, Start and Stop Services
Modify Registry Settings
Connect to a Remote Host
Upload and Download Files

---End Malware Capability---

The malware family has 2 versions. Both are nearly identical in functionality but use slightly different command codes. So if the opcode for Keepalive in version 1 is 0xB6C1, the opcode in version 2 will be 0xB6C2.

There may be some versions of the malware that have limited/additional functionality, but most will have these command codes:

---Begin Version 1 Command Codes---

0xB6A4 GetComputerlnfo
   -Gets OS Version
   -Opens and sends back multiple registry keys
       Keys are encrypted in actually binary using RC4 with 16 byte key (af 3d 78    23 4a 79 92 81 9d 7f 20 47 ad e3 f2 b3). Keys are decrypted prior to calling RegOpenKey/RegQueryValue.
   -Calls GetSystemlnfo, returns results of a SYSTEM_INFO struct
   -Calls GetSystemMetrics and returns results
0xB6AS GetDriveslnfo
   -Gets info about different drives/share drives on system as well as memory available/memory used on those drives
0xB6A6 Directorylist
   -Gives list of all files in a directory that is specified by the C2
0xB6A7 SendFile
   -Sends a file from the victim machine to the C2 that is specified by the C2
0xB6A8 ReceiveFile
   -Victim machine receives file from the C2
0xB6A9 CreateProcess
   -Calls CreateProcessW to run a process via the command line. C2 specifies the path of the file to be run via command line.
0xB6AA EnableLogging
   -Prior to victim and C2 closing out a connection the victim will spawn a new thread that will compile a comprehensive log of system/session information. Inside this thread it opens a file that is named randomly and places it in the temp directory. It puts all the log results into this file.
0xB6AB Deletefile
   -Deletes file specified by the C2.
0xB6AC RunCmdPipe
   -Runs CreateProcessW to run a process via the command line. The process will be cmd.exe and the arguments will be the windows cmd command that the C2 specifies. The results of this command will be sent to a temporary file and then read back to the C2 from that file. Afterwards that file is deleted.
0xB6AD Processlist
   -Gets a list of processes
0xB6AE KillProcess
   -Kills process based on the PID that the C2 supplies.
0xB6AF TestEncryption
   -Tests LFSR encryption, no real functionality
0xB6B0 Uninstall
   -Uninstalls the implant from the victim box
0xB6B2 GetConfig
   -Gets the current callback config file from memory, returns the list to C2. There are 10 IP options in this config.
0xB6B3 SetConfig
   -Gets the current callback config file from memory, allows C2 to change the configurations. This will change the beacon IP to whatever the C2 wants.
0xB6B4 SetCurrentDirectory
   -Changes current working directory to the path supplied by C2
0xB6B5 GetCurrentDirectory
   -Gets the current working directory and returns it to the C2
0xB6C1 KeepAlive
   -C2s sends this as a keep alive to the victim, victim responds with confirmation    that it received the keep alive and keeps session open

---End Version 1 Command Codes---

The malware is capable of opening and binding to a socket. The malware uses a public SSL certificate for secure communication. This certificate is from www.naver.com. Naver.com is the largest search engine in Korea and provides a variety of web services to clients around the world.

The malware uses the default certificates/private keys that come with PolarSSL. These are generally used for testing purposes only. Additionally the C2 IPs that act as the server for the TLS handshake require the malware to respond back with a client key. This key is also a default key found within the PolarSSL libraries.

---Begin SSL Certificate Header---

PolarSSL10UPolarSSL Test CA0
110212144407Z
2102121144407Z0<1 0 UNL10U
PolarSSL10UPolarSSL Client 200

---End SSL Certificate Header---

When executed, the malware will attempt a TLS Handshake with one of four hardcoded IP addresses embedded in the malware. These IP addresses are referenced in 'udbcgiut.dat' below. The malware also contains an embedded Zlib compression library that appears to further obfuscate the communications payload.

After the TLS authentication is completed this particular malware does NOT use the session key that is generated via TLS. It uses a custom Linear Feedback Shift Register (LFSR) encryption scheme to encrypt all communications after the completion of the handshake. A python script to decrypt traffic is given below:

Description

This artifact is a malicious PE32 executable with similar characteristics of those described in 23E27E5482E3F55BF828DAB885569033 above.

When this artifact is executed, it will write the file 'udbcgiut.dat' to C:\Users\<user>\AppData\Local\Temp.

The malware will then attempt outbound SSL connections to 81.94.192.147 and 112.175.92.57. Both connection attempts are over TCP Port 443.
The two IP addresses above, as well as the IP addresses 181.39.135.126 and 197.211.212.59 are hard-coded into the malware. However, only connections to the first two IP addresses were attempted during analysis.

Description

'udbcgiut.dat' is dropped by three of the four PE32 executables. This file contains a 32byte unicode string uniquely generated for the infected system, as well as four socket pairs in hexidecimal.

---Begin Decoded Socket Pairs---

197.211.212.59:443
181.39.135.126:443
112.175.92.57:7443
81.94.192.147:7443

---End Decoded Socket Pairs---

The unicode string generated during this analysis was '8a9b11762b96c4b6'. The socket pairs remain the same for all instances of the malware.
For the PE32 executables, 'udbcgiut.dat' was dropped in the victim's profile at %AppData%\Local\Temp. For the 64bit executables, 'udbcgiut.dat' was dropped in C:\Windows.

Description

This artifact is a malicious PE32 executable with similar characteristics of those described in 23E27E5482E3F55BF828DAB885569033 above.

This program attempts to initiate a TLS Handshake to the four IP/Port pairs listed in 'udbcgiut.dat'. If the program is unable to establish a connection, the file 'udbcgiut.dat' is deleted.

After 'udbcgiut.dat' is deleted, an outbound SSL connection is made to 81.94.192.10. The IP address is hard coded in the malware and are not randomly generated.

This artifact also loads several APIs that are commonly associated with Pass-The-Hash (PTH) toolkits, indicating a capability to harvest user credentials and passwords.

Description

This artifact is a malicious x64 executable with similar characteristics of those described in 23E27E5482E3F55BF828DAB885569033 above.

In addition to the capabilities described above, this variant will hook the Windows Local Security Authority (lsass.exe). 'lsass.exe' will check the registry for the data value 'rdpproto' under the key SYSTEM\CurrentControlSet\Control\Lsa Name: Security Packages. If not found, this value is added by 'lsass.exe'.
Next, the malware will drop the embedded file, 'rdpproto.dll' into the %System32% directory.
The file, 'udbcgiut.dat' is then written to C:\Windows. Outbound connection attempts are made to the socket pairs found within this file as described above.

Description

This artifact is 64bit Windows dynamic library file which shares many of the same characteristics and name (Vote_Controller.dll) as 42682D4A78FE5C2EDA988185A344637D above.

When this library is loaded it will look for the file 'udbcgiut.dat' in C:\WINDOWS. If 'udbcgiut.dat' is not found, the file will attempt connections to the same ten IP addresses described under 'rdpproto.dll' above.

One notable difference with this variant is that it uses the Windows Management Instrumentation (WMI) process to recompile the Managed Object Format (MOF) files in the WMI repository. At runtime, the malware will enumerate the drivers located in the registry at HKLM\Software\WBEM\WDM.
These files are then recompiled by invoking wmiprvse.exe through svchost.exe: "C:\Windows\system32\wbem\wmiprvse.exe -Embedding".
MOF files are written in a SQL-like language and are run (compiled) by the operating system when a predetermined event takes place. Recent malware variants have been observed modifying the MOF files within the system registry to run specific commands and create persistency on the system.

Of note, the paravirtual SCSI driver for VMWare Tools is also located in HKLM\Software\WBEM\WDM within a virtual image. When this driver is recompiled by the malware, VMWare Tools no longer works. It cannot be determined if this is an intentional characteristic of the malware to hinder analysis, or simply a symptom of the method used to establish persistence.

Description

This artifact is a malicious PE32 executable. When executed, the artifact sets up the service, 'Network UDP Trace Management Service'.
To set up the service, the program drops a dynamic library, 'UDPTrcSvc.dll' into the %System32% directory.
Next, the following registry keys are added:

---Begin Registry Keys---

HKLM\SYSTEM\CurrentControlSet\services\UDPTrcSvc Name: Type Value: 20
HKLM\SYSTEM\CurrentControlSet\services\UDPTrcSvc Name: Start Value: 02
HKLM\SYSTEM\CurrentControlSet\services\UDPTrcSvc Name: ImagePath Value: "%SystemRoot%\System32\svchost.exe -k mdnetuse"
HKLM\SYSTEM\CurrentControlSet\services\UDPTrcSvc Name: DisplayName Value: "Network UDP Trace Management Service"
HKLM\SYSTEM\CurrentControlSet\services\UDPTrcSvc Name: ObjectName Value: "LocalSystem"
HKLM\SYSTEM\CurrentControlSet\services\UDPTrcSvc\Parameters Name: ServiceDll Value: "%SystemRoot%\System32\svchost.exe -k mdnetuse"
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Svchost\mdnetuse

---End Registry Keys---

The service is started by invoking svchost.exe.

After writing 'UDPTrcSvd.dll' to disk, the program drops two additional files. Similar to 5C3898AC7670DA30CF0B22075F3E8ED6 above, the program writes the file 'udbcgiut.dat' to the victim's profile at %AppData/Local/Temp%. A second file is written to the victim's profile in the %AppData/Local/VirtualStore/Windows% directory and identified as 'MSDFMAPI.INI'. 'MSDFMAPI.INI' is also written to C:\WINDOWS. More information on the content of these files is below.

61E3571B8D9B2E9CCFADC3DDE10FB6E1 attempts the same outbound connections as 5C3898AC7670DA30CF0B22075F3E8ED6, however the file does not contain any of the public SSL certificates referenced above.

Description

This artifact is a malicious 64bit Windows dynamic library. When run the malware drops a Themida packed DLL. This DLL runs and drops another DLL that acts as the Remote admin tool. This RAT is very similar to version 2 in op codes and functionality however it uses real TLS instead of the LFSR encryption. Additionally it encodes it's data with XOR Ox47 SUB Ox28 prior to being TLS encrypted.

Description

This artifact is a malicious PE32 executable that is an add-on tool for other Hoplight implants.

When malware is run it opens a log file C:\WINDOWS\Temp\ndb.dat that is used for the remainder of the program to log all activity.

The malware runs with an IP as an argument. It sends out a beacon to this IP and connects to it using the same FakeTLS/PolarSSL protocol as the other samples. After a successful connection to a C2, it uses a named pipe called \\\\.\\pipe\\AnonymousPipe to connect to a running implant and sends tasking to the running implant. The implant returns the results of these taskings over the named pipe and the malware sends the results back to the C2.

Recommendations

CISA recommends that users and administrators consider using the following best practices to strengthen the security posture of their organization's systems. Any configuration changes should be reviewed by system owners and administrators prior to implementation to avoid unwanted impacts.

  • Maintain up-to-date antivirus signatures and engines.
  • Keep operating system patches up-to-date.
  • Disable File and Printer sharing services. If these services are required, use strong passwords or Active Directory authentication.
  • Restrict users' ability (permissions) to install and run unwanted software applications. Do not add users to the local administrators group unless required.
  • Enforce a strong password policy and implement regular password changes.
  • Exercise caution when opening e-mail attachments even if the attachment is expected and the sender appears to be known.
  • Enable a personal firewall on agency workstations, configured to deny unsolicited connection requests.
  • Disable unnecessary services on agency workstations and servers.
  • Scan for and remove suspicious e-mail attachments; ensure the scanned attachment is its "true file type" (i.e., the extension matches the file header).
  • Monitor users' web browsing habits; restrict access to sites with unfavorable content.
  • Exercise caution when using removable media (e.g., USB thumb drives, external drives, CDs, etc.).
  • Scan all software downloaded from the Internet prior to executing.
  • Maintain situational awareness of the latest threats and implement appropriate Access Control Lists (ACLs).
