Cybersecurity and Infrastructure Security Agency Logo National Cyber Awareness System: AR19-304A: MAR-10135536-8 North Korean Trojan: HOPLIGHT [ https://www.us-cert.gov/ncas/analysis-reports/ar19-304a ] 10/31/2019 10:57 AM EDT Original release date: October 31, 2019 Description Notification This report is provided "as is" for informational purposes only. The Department of Homeland Security (DHS) does not provide any warranties of any kind regarding any information contained herein. The DHS does not endorse any commercial product or service referenced in this bulletin or otherwise. This document is marked TLP:WHITE--Disclosure is not limited. Sources may use TLP:WHITE when information carries minimal or no foreseeable risk of misuse, in accordance with applicable rules and procedures for public release. Subject to standard copyright rules, TLP:WHITE information may be distributed without restriction. For more information on the Traffic Light Protocol (TLP), see http://www.us-cert.gov/tlp. 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--- 1 0 UNL10U 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: ---Begin LFSR Decryption Script--- class lfsr: def _init_(self): self.b = (0, 0, 0, 0) self.data = b" self.L= 0 def lfsr_init(self, data): self.L = len(data) self.data = data self.b[0] = 0 self.b[1] = 0xc2b45678 self.b[2] = 0x90abcdef self.b[3] = 0xfe268455 for i in range(int(self.L / 3)): self.b[1] ^= self.b[2] self.b[2] ^= self.b[3] self.b[3] ^= self.b[1] for i in range{self.L % 3): self.b[1] |= self.b[2] self.b[2] |= self.b[3] self.b[3] |= self.b[1] def lfsr_1(self): r = 0 if (self.b[1] & 0x200) == 0x200: r += 1 if (self.b[2] & 0x800) == 0x800: r += 1 if (self.b[3] & 0x800) == 0x800: r += 1 if r <= 1: self.b[0] = 1 else: self.b[0] = 0 def lfsr_2(self): v1 = self.b[1] r = (self.b[1] >> 9) & 1 v3 = r == self.b[0] self.b[0] ^= r if not v3: r = (v1 ^ ((v1 ^ (( v1 ^ (v1 >> 1)) >> 1)) >> 3)) >> 13 v4 = 2 * (v1 & 0x3ffff) self.b[1] = v4 if (r & 1): self.b[1] = v4 ^ 1 def lfsr_3(self): v1 = self.b[2] r = (self.b[2] >> 11) & 1 v3 = r == self.b[0] self.b[0] ^= r if not v3: r = (v1 ^ ((v1 ^ ((v1 ^ (v1 >> 1)) >> 4)) >> 4)) >> 12 v4 = 2 * (v1 & 0x1fffff) self.b[2] = v4 if (r & 1): self.b[2] = v4 ^ 1 def lfsr 4(self): v1 = self.b[3] r = (self.b[3] >> 11) & 1 v3 = r == self.b[0] self.b[0] ^= r if not v3: r = (v1 ^ ((v1 ^ ((v1 ^ (v1 >> 1)) >> 3)) >> 1)) >> 17 v4 = 2 * (v1 & 0x3fffff) self.b[3] = v4 if (r & 1): self.b[3] = v4 ^ 1 def lfsr_genKeyByte(self): self.lfsr_1() self.lfsr_2() self.lfsr_3() self.lfsr_4() v2 = self.b[1] ^ self.b[2] ^ self.b[3] r = (v2 >> 0x18) ^ (v2 >> 0x10) ^ (v2 >> 0x8) ^ v2 r &= 0xff return r def crypt(self): r= b" for i in range(len(self.data)): k = self.lfsr_genKeyByte() r += bytes([self.data[i] ^ k]) return r ---End LFSR Decryption Script--- The following notable strings have been linked to the use of the SSL certificates and can be used to identify the malware: ---Begin Notable Strings--- fjiejffndxklfsdkfjsaadiepwn ofuierfsdkljffjoiejftyuir reykfgkodfgkfdskgdfogpdokgsdfpg ztretrtireotreotieroptkierert etudjfirejer yrty uiyy uiyiyj lildvucv erfdfe poiiumwq ---End Notable Strings--- The next four artifacts contain identical characteristics as those described 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. 49757cf85657757704656c079785c072bbc233cab942418d99d1f63d43f28359 Tags trojan Details Name rdpproto.dll Size 391680 bytes Type PE32+ executable (DLL) (console) x86-64, for MS Windows MD5 dc268b166fe4c1d1c8595dccf857c476 SHA1 8264556c8a6e460760dc6bb72ecc6f0f966a16b8 SHA256 49757cf85657757704656c079785c072bbc233cab942418d99d1f63d43f28359 SHA512 b47c4caa0b5c17c982fcd040c7171d36ec962fe32e9b8bec567ee14b187507fe90e026aa05eec17d36c49a924eeaed55e66c95a111cfa9dcae0e305ab9515cac ssdeep 6144:jfsTC8amAXJeZP6BPjIDeLkigDxcvAHjVXjhtBGshMLa1Mj7rtlkiP60dwtudIye:jvg+Rg1cvAHtE0MLa07rt5POui6 Entropy 7.893665 Antivirus Ahnlab Trojan/Win64.Hoplight Antiy Trojan/Win32.Casdet Avira TR/Crypt.XPACK.xuqld BitDefender Trojan.Generic.22790108 ESET a variant of Win64/NukeSped.BV trojan Emsisoft Trojan.Generic.22790108 (B) Ikarus Trojan.SuspectCRC K7 Trojan ( 0054bb211 ) McAfee Hoplight-FDXG!DC268B166FE4 Microsoft Security Essentials Trojan:Win64/Hoplight NANOAV Trojan.Win64.Crypted.excqpl Quick Heal Trojan.Agent Sophos Troj/Hoplight-C Symantec Trojan.Hoplight VirusBlokAda Trojan.Win64.Agent Yara Rules No matches found. ssdeep Matches 99 890d3928be0f36b1f4dcfffb20ac3747a31451ce010caba768974bfccdc26e7c PE Metadata Compile Date 2017-06-06 11:34:06-04:00 Import Hash 360d26520c50825099ec61e97b01a43b PE Sections MD5 Name Raw Size Entropy 3bb2a7d6aab283c82ab853f536157ce2 header 1024 2.524087 b0bf8ec7b067fd3592c0053702e34504 .text 23552 6.180871 6cc98c5fef3ea1b782262e355b5c5862 .rdata 10752 4.635336 484d4698d46b3b5ad033c1a80ba83acf .data 4096 2.145716 a07c8f17c18c6789a3e757aec183aea6 .pdata 2048 3.729952 fae0d0885944745d98849422bd799457 .rsrc 348672 7.997488 0c1c23e1fb129b1b1966f70fc75cf20e .reloc 1536 1.737829 Relationships 49757cf856...

Connected_To 112.175.92.57 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. 70034b33f59c6698403293cdc28676c7daa8c49031089efa6eefce41e22dccb3 Tags trojan Details Name 61E3571B8D9B2E9CCFADC3DDE10FB6E1 Size 258052 bytes Type PE32 executable (GUI) Intel 80386, for MS Windows MD5 61e3571b8d9b2e9ccfadc3dde10fb6e1 SHA1 55daa1fca210ebf66b1a1d2db1aa3373b06da680 SHA256 70034b33f59c6698403293cdc28676c7daa8c49031089efa6eefce41e22dccb3 SHA512 235f7b920f54c4d316386cbf6cc14db1929029e8053270e730be15acc8e9f333231d2d984681bea26013a1d1cf4670528ba0989337be13ad4ada3eeba33bdfe8 ssdeep 6144:d71TKN7LBHvS+bujAfrsxwkm1Ka5l7gTtJUGx:dxKHPuj8WR0K6VgTtZx Entropy 7.829590 Antivirus Ahnlab Trojan/Win32.Hoplight Antiy Trojan/Win32.NukeSped Avira TR/NukeSped.oppme BitDefender Dropped:Trojan.Generic.22954895 Emsisoft Dropped:Trojan.Generic.22954895 (B) Ikarus Trojan.Win32.NukeSped K7 Trojan ( 005329311 ) McAfee Trojan-Hoplight Microsoft Security Essentials Trojan:Win32/Nukesped.PA!MTB NANOAV Trojan.Win32.NukeSped.fpblwf NetGate Trojan.Win32.Malware Quick Heal Trojan.Generic Sophos Troj/Hoplight-C Symantec Trojan.Gen.MBT TrendMicro Trojan.55DEE3DA TrendMicro House Call Trojan.55DEE3DA Yara Rules hidden_cobra_consolidated.yara rule crypt_constants_2 { meta: Author = "CISA trusted 3rd party" Incident = "10135536" Date = "2018-04-19" Category = "Hidden_Cobra" Family = "n/a" Description = "n/a" strings: $ = {efcdab90} $ = {558426fe} $ = {7856b4c2} condition: (uint16(0) == 0x5A4D and uint16(uint32(0x3c)) == 0x4550) and all of them } ssdeep Matches No matches found.

Additionally it encodes it's data with XOR Ox47 SUB Ox28 prior to being TLS encrypted. 73dcb7639c1f81d3f7c4931d32787bdf07bd98550888c4b29b1058b2d5a7ca33 Tags trojan Details Name 3EDCE4D49A2F31B8BA9BAD0B8EF54963 Size 147456 bytes Type PE32 executable (DLL) (GUI) Intel 80386, for MS Windows MD5 3edce4d49a2f31b8ba9bad0b8ef54963 SHA1 1209582451283c46f29a5185f451aa3c989723c9 SHA256 73dcb7639c1f81d3f7c4931d32787bdf07bd98550888c4b29b1058b2d5a7ca33 SHA512 0d3de1758b44597ccc4dad46a9b42626237da425a41b8833bf7549a3c809bd7432ce938cd8757b362e2268bead45a0b212c96cc881737cf0e6952097280d7277 ssdeep 3072:bQGYFFzsaXlvJdbx9NAzDZWaNoh05WKRYW7IWwh7:bSFhLlh9N8DZWaNoG5W8VIWC Entropy 6.605430 Antivirus Ahnlab Trojan/Win32.Akdoor Antiy Trojan/Win32.Autophyte Avira TR/AD.APTLazerus.jtxjg BitDefender Gen:Variant.Zusy.290462 Cyren W32/Trojan.DXJJ-0934 ESET a variant of Win32/NukeSped.AU trojan Emsisoft Gen:Variant.Zusy.290462 (B) Ikarus Trojan.Win32.NukeSped K7 Trojan ( 0052cf421 ) McAfee Trojan-HidCobra Microsoft Security Essentials Trojan:Win32/Autophyte.E!dha NetGate Trojan.Win32.Malware Quick Heal Trojan.Generic Sophos Troj/NukeSpe-I Symantec Trojan.Hoplight TrendMicro BKDR_HO.9D36C86C TrendMicro House Call BKDR_HO.9D36C86C VirusBlokAda Trojan.Autophyte Zillya!

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. fe43bc385b30796f5e2d94dfa720903c70e66bc91dfdcfb2f3986a1fea3fe8c5 Tags trojan Details Name F315BE41D9765D69AD60F0B4D29E4300 Size 147456 bytes Type PE32 executable (DLL) (GUI) Intel 80386, for MS Windows MD5 f315be41d9765d69ad60f0b4d29e4300 SHA1 f60c2bd78436a14e35a7e85feccb319d3cc040eb SHA256 fe43bc385b30796f5e2d94dfa720903c70e66bc91dfdcfb2f3986a1fea3fe8c5 SHA512 bc8f821b4989076e441fbe5668cee0a388adcc375fac4a553f4c27423cd61c4500739820033b32f4197820ddf34decf1a043c6d34619aa18e1a932feb4e4233b ssdeep 3072:pQWbIWSG5bzxbT33FiDZWTNArLioB4Gwhes:pR3SGtJ33YDZWTNMLiGah Entropy 6.477832 Antivirus Ahnlab Trojan/Win32.Agent Antiy Trojan/Win32.Autophyte Avira TR/AD.APTLazerus.ifaaj BitDefender Gen:Variant.Graftor.487501 Cyren W32/Trojan.CTPG-1488 ESET a variant of Win32/NukeSped.AU trojan Emsisoft Gen:Variant.Graftor.487501 (B) Ikarus Trojan.Win32.NukeSped K7 Trojan ( 0052cf421 ) McAfee Trojan-HidCobra Microsoft Security Essentials Trojan:Win32/Autophyte.E!dha NetGate Trojan.Win32.Malware Quick Heal Trojan.Generic Sophos Troj/NukeSpe-D Symantec Trojan Horse TrendMicro BKDR_HO.9D36C86C TrendMicro House Call BKDR_HO.9D36C86C VirusBlokAda BScope.Trojan.Autophyte Zillya!

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). Additional information on malware incident prevention and handling can be found in National Institute of Standards and Technology (NIST) Special Publication 800-83, *"Guide to Malware Incident Prevention & Handling for Desktops and Laptops".* Contact Information * 1-888-282-0870 * NCCICCustomerService () us-cert gov [ https://www.us-cert.govmailto:NCCICCustomerService () us-cert gov ] (UNCLASS) * us-cert () dhs sgov gov [ https://www.us-cert.govmailto:us-cert () dhs sgov gov ] (SIPRNET) * us-cert () dhs ic gov [ https://www.us-cert.govmailto:us-cert () dhs ic gov ] (JWICS) CISA continuously strives to improve its products and services.
