What is Joanap in COBRA’s IT Operations?
Joanap is a remote access trojan (RAT) that is used by HIDDEN COBRA actors to establish peer-to-peer communications and manage botnets for various cyber operations. It is a fully functional RAT that can receive multiple commands from the command and control server controlled by the North Korean government. Joanap can perform tasks such as exfiltrating data, downloading and running additional malware, initializing proxy communications, and managing files and processes on compromised Windows devices.
It is typically delivered as a file dropped by other malware, either through compromised websites or malicious email attachments. Once installed, Joanap encrypts its communication with the command and control server using Rivest Cipher 4 encryption.
Characteristics of Joanap:
- Acts as a remote access trojan (RAT)
- Establishes peer-to-peer communications
- Manages botnets for cyber operations
- Receives commands from the command and control server
- Exfiltrates data
- Downloads and runs additional malware
- Initializes proxy communications
- Manages files and processes on compromised Windows devices
- Encrypts communication with Rivest Cipher 4 encryption
Joanap plays a crucial role in COBRA’s IT operations, enabling them to gain unauthorized access, control compromised systems, and carry out malicious activities. Understanding the characteristics of Joanap helps in recognizing and mitigating the risks associated with HIDDEN COBRA attacks.
Joanap is a versatile remote access trojan used by HIDDEN COBRA to establish communication channels and manage botnets. Its ability to perform various tasks makes it a powerful tool for executing cyber operations.

| Rivest Cipher 4 Encryption | Secures communication with the command and control server |
Understanding Brambul, the SMB Worm Used by COBRA
Brambul is an SMB worm used by HIDDEN COBRA for network exploitation. It takes advantage of the Server Message Block (SMB) protocol, similar to the WannaCry ransomware, to propagate and infect other systems. This worm operates as either a service dynamic link library file or a portable executable file, often infiltrating victim networks through dropper malware.
Once executed, Brambul employs brute-force password attacks, using a pre-determined list of embedded passwords, in an attempt to gain unauthorized access to victim systems. It establishes communication with the command and control server via email, sending vital information about the compromised systems such as IP addresses, hostnames, and usernames, along with passwords. Additionally, Brambul possesses the capability to generate and execute a “suicide script”.
Understanding the characteristics and behavior of Brambul is crucial for effective network defense against COBRA’s cyber attacks. By identifying its entry points, utilizing secure authentication systems, and implementing robust password policies, organizations can enhance their network security and minimize the risk of Brambul infection.
“The Brambul worm is a significant threat to network security, utilizing SMB vulnerabilities to spread and exploit victim systems. Understanding its behavior and implementing adequate defense measures is crucial for safeguarding against COBRA’s malicious activities.”
To further illustrate the impact of Brambul, here is a table highlighting its key characteristics:
| Characteristic | Description |
|---|---|
| Propagation | Utilizes the SMB protocol to spread and infect other systems. |
| Infiltration | Often delivered and installed on victim networks through dropper malware. |
| Unauthorized Access | Launches brute-force password attacks to gain entry into victim systems. |
| Communication | Sends information about compromised systems to the command and control server via email. |
| Suicide Script | Has the capability to generate and execute a “suicide script” on infected systems. |
As demonstrated, Brambul poses a significant threat to network security. Understanding its characteristics allows organizations to implement appropriate defense strategies and minimize the potential damage caused by COBRA’s cyber operations.
Network Security Implications of COBRA’s Activities
The activities of HIDDEN COBRA have far-reaching implications for network security. These actors often target systems running older, unsupported versions of Microsoft operating systems, taking advantage of vulnerabilities in these systems. Moreover, they exploit vulnerabilities in applications such as Hangul Word Processor, Adobe Flash Player, and Microsoft Silverlight to gain initial entry into users’ environments.
To mitigate the risk of COBRA attacks, it is highly recommended that organizations upgrade their applications to the latest versions and patch levels. By doing so, they can effectively mitigate the vulnerabilities that COBRA actors exploit. Network administrators should also closely monitor network perimeter logs for any IP addresses associated with HIDDEN COBRA and take immediate measures to remove any detected malware.
The Impact of COBRA’s Targeting Strategy
COBRA’s deliberate focus on older, unsupported systems and vulnerable applications poses a significant challenge for network defenders. Without proper network defense measures, organizations may remain exposed to COBRA’s malicious cyber activities and the potential repercussions that follow.
