AA22-108A: TraderTraitor: North Korean State-Sponsored APT Targets Blockchain Companies

Original release date: April 18, 2022

Summary

Actions to take today to mitigate cyber threats to cryptocurrency:

• Patch all systems.

• Prioritize patching known exploited vulnerabilities.

• Train users to recognize and report phishing attempts.

• Use multifactor authentication.

The Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), and the U.S. Treasury Department (Treasury) are issuing this joint Cybersecurity Advisory (CSA) to highlight the cyber threat associated with cryptocurrency thefts and tactics used by a North Korean state-sponsored advanced persistent threat (APT) group since at least 2020. This group is commonly tracked by the cybersecurity industry as Lazarus Group, APT38, BlueNoroff, and Stardust Chollima. For more information on North Korean state-sponsored malicious cyber activity, visit https://www.us-cert.cisa.gov/northkorea.

The U.S. government has observed North Korean cyber actors targeting a variety of organizations in the blockchain technology and cryptocurrency industry, including cryptocurrency exchanges, decentralized finance (DeFi) protocols, play-to-earn cryptocurrency video games, cryptocurrency trading companies, venture capital funds investing in cryptocurrency, and individual holders of large amounts of cryptocurrency or valuable non-fungible tokens (NFTs). The activity described in this advisory involves social engineering of victims using a variety of communication platforms to encourage individuals to download trojanized cryptocurrency applications on Windows or macOS operating systems. The cyber actors then use the applications to gain access to the victim's computer, propagate malware across the victim's network environment, and steal private keys or exploit other security gaps. These activities enable additional follow-on activities that initiate fraudulent blockchain transactions.

The U.S. government previously published an advisory about North Korean state-sponsored cyber actors using AppleJeus malware to steal cryptocurrency: AppleJeus: Analysis of North Korea's Cryptocurrency Malware. The U.S. government has also previously published advisories about North Korean state-sponsored cyber actors stealing money from banks using custom malware:

• HIDDEN COBRA – FASTCash Campaign


• FASTCash 2.0: North Korea's BeagleBoyz Robbing Banks

This advisory provides information on tactics, techniques, and procedures (TTPs) and indicators of compromise (IOCs) to stakeholders in the blockchain technology and cryptocurrency industry to help them identify and mitigate cyber threats against cryptocurrency.

Technical Details

Threat Update

The U.S. government has identified a group of North Korean state-sponsored malicious cyber actors using tactics similar to the previously identified Lazarus Group (see AppleJeus: Analysis of North Korea's Cryptocurrency Malware). The Lazarus Group used AppleJeus trojanized cryptocurrency applications targeting individuals and companies—including cryptocurrency exchanges and financial services companies—through the dissemination of cryptocurrency trading applications that were modified to include malware that facilitates theft of cryptocurrency. As of April 2022, North Korea's Lazarus Group actors have targeted various firms, entities, and exchanges in the blockchain and cryptocurrency industry using spearphishing campaigns and malware to steal cryptocurrency. These actors will likely continue exploiting vulnerabilities of cryptocurrency technology firms, gaming companies, and exchanges to generate and launder funds to support the North Korean regime. 

Tactics, Techniques and Procedures

Intrusions begin with a large number of spearphishing messages sent to employees of cryptocurrency companies—often working in system administration or software development/IT operations (DevOps)—on a variety of communication platforms. The messages often mimic a recruitment effort and offer high-paying jobs to entice the recipients to download malware-laced cryptocurrency applications, which the U.S. government refers to as "TraderTraitor."

The term TraderTraitor describes a series of malicious applications written using cross-platform JavaScript code with the Node.js runtime environment using the Electron framework. The malicious applications are derived from a variety of open-source projects and purport to be cryptocurrency trading or price prediction tools. TraderTraitor campaigns feature websites with modern design advertising the alleged features of the applications (see figure 1).

 

Figure 1: Screenshot of CryptAIS website

The JavaScript code providing the core functions of the software is bundled with Webpack. Within the code is a function that purports to be an "update," with a name such as UpdateCheckSync(), that downloads and executes a malicious payload (see figure 2). 

The update function makes an HTTP POST request to a PHP script hosted on the TraderTraitor project's domain at either the endpoint /update/ or /oath/checkupdate.php. In recent variants, the server's response is parsed as a JSON document with a key-value pair, where the key is used as an AES 256 encryption key in Cipher Block Chaining (CBC) or Counter (CTR) mode to decrypt the value. The decrypted data is written as a file to the system's temporary directory, as provided by the os.tmpdir() method of Node.js, and executed using the child_process.exec() method of Node.js, which spawns a shell as a child process of the current Electron application. The text "Update Finished" is then logged to the shell for the user to see.

Observed payloads include updated macOS and Windows variants of Manuscrypt, a custom remote access trojan (RAT), that collects system information and has the ability to execute arbitrary commands and download additional payloads (see North Korean Remote Access Tool: COPPERHEDGE). Post-compromise activity is tailored specifically to the victim's environment and at times has been completed within a week of the initial intrusion.

Indicators of Compromise

DAFOM

DAFOM purports to be a "cryptocurrency portfolio application." A Mach-O binary packaged within the Electron application was signed by an Apple digital signature issued for the Apple Developer Team W58CYKFH67. The certificate associated with Apple Developer Team W58CYKFH67 has been revoked. A metadata file packaged in the DAFOM application provided the URL hxxps://github[.]com/dafomdev for bug reports. As of April 2022, this page was unavailable.

TokenAIS

TokenAIS purports to help "build a portfolio of AI-based trading" for cryptocurrencies. Mach-O binaries packaged within the Electron application contained an Apple digital signature issued for the Apple Developer Team RN4BTXA4SA. The certificate associated with Apple Developer Team RN4BTXA4SA has been revoked. The application requires users to "register" an account by entering an email address and a password to use its features. The malicious TraderTraitor code is a Node.js function called UpdateCheckSync() located in a file named update.js, which is bundled in a file called renderer.prod.js, which is in an archive called app.asar. This function passes the email address that the user provided and the system platform to the C2 server, decrypts the response using AES 256 in CBC mode with the hardcoded initialization vector (IV) !@34QWer%^78TYui and a key provided in the response, then writes the decrypted data to a file and executes it in a new shell.

AlticGO

AlticGO was observed packaged as Nullsoft Scriptable Install System (NSIS) Windows executables that extracted an Electron application packaged for Windows. These executables contain a simpler version of TraderTraitor code in a function exported as UpdateCheckSync() located in a file named update.js, which is bundled in renderer.prod.js, which is in the app.asar archive. The function calls an external function located in a file node_modules/request/index.js bundled in renderer.prod.js to make an HTTP request to hxxps://www.alticgo[.]com/update/. One AlticGO sample, e3d98cc4539068ce335f1240deb1d72a0b57b9ca5803254616ea4999b66703ad, instead contacts hxxps://www.esilet[.]com/update/ (see below for more information about Esilet). Some image resources bundled with the application included the CreAI Deck logo (see below for more information about CreAI Deck). The response is written to disk and executed in a new shell using the child_process.exec() method in Node.js. Unlike newer versions of TraderTraitor, there is no mechanism to decrypt a payload.

Esilet

Esilet claims to offer live cryptocurrency prices and price predictions. It contains a simpler version of TraderTraitor code in a function exported as UpdateCheckSync() located in a file named update.js, which is bundled in renderer.prod.js, which is in the app.asar archive. The function calls an external function located in a file node_modules/request/index.js bundled in renderer.prod.js to make an HTTP request to hxxps://www.esilet[.]com/update/. The response is written to disk and executed in a new shell using the child_process.exec() method in Node.js. Unlike newer versions of TraderTraitor, there is no mechanism to decrypt a payload. Esilet has been observed delivering payloads of at least two different macOS variants of Manuscrypt, 9d9dda39af17a37d92b429b68f4a8fc0a76e93ff1bd03f06258c51b73eb40efa and dced1acbbe11db2b9e7ae44a617f3c12d6613a8188f6a1ece0451e4cd4205156.

CreAI Deck

CreAI Deck claims to be a platform for "artificial intelligence and deep learning." No droppers for it were identified, but the filenames of the below samples, win32.bin and darwin64.bin, match the naming conventions used by other versions of TraderTraitor when downloading a payload. Both are samples of Manuscrypt that contact hxxps://aideck[.]net/board.php for C2 using HTTP POST requests with multipart/form-data Content-Types.

Mitigations

North Korean state-sponsored cyber actors use a full array of tactics and techniques to exploit computer networks of interest, acquire sensitive cryptocurrency-intellectual property, and gain financial assets. The U.S. government recommends implementing mitigations to protect critical infrastructure organizations as well as financial sector organizations in the blockchain technology and cryptocurrency industry.

• Apply defense-in-depth security strategy. Apply security principles—such as least access models and defense-in-depth—to user and application privileges to help prevent exploitation attempts from being successful. Use network segmentation to separate networks into zones based on roles and requirements. Separate network zones can help prevent lateral movement throughout the organization and limit the attack surface. See NSA's Top Ten Cybersecurity Mitigation Strategies for strategies enterprise organizations should use to build a defense-in-depth security posture. 


• Implement patch management. Initial and follow-on exploitation involves leveraging common vulnerabilities and exposures (CVEs) to gain access to a networked environment. Organizations should have a timely vulnerability and patch management program in place to mitigate exposure to critical CVEs. Prioritize patching of internet-facing devices and monitored accordingly for any malicious logic attacks. 


• Enforce credential requirements and multifactor authentication. North Korean malicious cyber actors continuously target user credentials, email, social media, and private business accounts. Organizations should ensure users change passwords regularly to reduce the impact of password spraying and other brute force techniques. The U.S. government recommends organizations implement and enforce multifactor authentication (MFA) to reduce the risk of credential theft. Be aware of MFA interception techniques for some MFA implementations and monitor for anomalous logins.


• Educate users on social engineering on social media and spearphishing. North Korean actors rely heavily on social engineering, leveraging email and social media platforms to build trust and send malicious documents to unsuspecting users. A cybersecurity aware workforce is one of the best defenses against social engineering techniques like phishing. User training should include how to identify social engineering techniques and awareness to only open links and attachments from trusted senders.


• Implement email and domain mitigations. Maintain awareness of themed emails surrounding current events. Malicious cyber actors use current events as lure for potential victims as observed during the COVID-19 pandemic. Organizations should have a robust domain security solution that includes leveraging reputation checks and closely monitoring or blocking newly registered domains (NRDs) in enterprise traffic. NRDs are commonly established by threat actors prior to malicious engagement.
  
  
  
  • HTML and email scanning. Organizations should disable HTML from being used in emails and scan email attachments. Embedded scripts may be hard for an antivirus product to detect if they are fragmented. An additional malware scanning interface product can be integrated to combine potentially malicious payloads and send the payload to the primary antivirus product. Hyperlinks in emails should also be scanned and opened with precautionary measures to reduce the likelihood of a user clicking on a malicious link.
  
  
  
  


• Endpoint protection. Although network security is critical, devices mobility often means traveling and connecting to multiple different networks that offer varying levels of security. To reduce the risk of introducing exposed hosts to critical networks, organizations should ensure mobile devices have installed security suites to detect and mitigate malware. 


• Enforce application security. Application allowlisting enables the organization to monitor programs and only allow those on the approved allowlist to execute. Allowlisting helps to stop the initial attack, even if the user clicks a malicious link or opens a malicious attachment. Implement baseline rule sets, such as NSA's Limiting Location Data Exposure guidance, to block execution of unauthorized or malicious programs.
  
  
  
  • Disable macros in office products. Macros are a common method for executing code through an attached office document. Some office products allow for the disabling of macros that originate from outside of the organization, providing a hybrid approach when the organization depends on the legitimate use of macros.
    
    
    
    • Windows specific settings can be configured to block internet-originated macros from running. This can be done in the Group Policy Administrative Templates for each of the associated Office products (specifically Word, Excel and PowerPoint). Other productivity software, such as LibreOffice and OpenOffice, can be configured to set the Macro Security Level.
    
    
    
    
  
  
  
  


• Be aware of third-party downloads—especially cryptocurrency applications. North Korean actors have been increasingly active with currency generation operations. Users should always verify file downloads and ensure the source is from a reputable or primary (preferred) source and not from a third-party vendor. Malicious cyber actors have continuously demonstrated the ability to trojanize applications and gain a foothold on host devices.


• Create an incident response plan to respond to possible cyber intrusions. The plan should include reporting incidents to both the FBI and CISA—quick reporting can reduce the severity of incidents and provide valuable information to investigators. Contact information can be found below.
