Threat Overview
AlienVault has recently published a threat report highlighting the activities of a nation-state actor known as Secret Blizzard. This actor group, associated with Russia, has been observed using tools and infrastructure from other malicious actors to compromise targets in Ukraine.
Background
In between March and April 2024, Secret Blizzard utilised the Amadey bot malware associate with cybercriminal activity for deployment purposes as well. Moreover, in January 2024, Secret Blizzard leveraged a backdoor from Storm-1837 to install its malware.
Scope
The attack was conducted against Ukrainian military targets and involved multiple attack vectors including strategic web compromises, adversary-in-the-middle campaigns, and spear-phishing for the initial access.
Tactics, Techniques, and Procedures (TTPs)
Secret Blizzard’s approach to attacking targets is diverse and innovative. The actor employs various techniques including:
Strategic Web Compromises: Targeting websites and domains belonging to Ukrainian military institutions.
Adversary-in-the-Middle: Intercepting communications between servers, devices, or networks.
Access Vector
Secret Blizzard utilized Amadey bot malware associated with cybercriminal activity for deployment purposes. Additionally, in January 2024, Secret Blizzard leveraged a backdoor from Storm-1837 to install its malware.
Prior exploitation techniques used by the actor include:
Amadey Bot Malware: The amadey bot malware was exploited for deployment purposes as well. This malware is also associated with cybercriminal activity and provides the attacker with malicious code for compromise.
Tools and Infrastructure Used
Secret Blizzard has used tools and infrastructure from other threat actors, including:
Tavdig and KazuarV2 Backdoors: The Tavdig and KazuarV2 backdoors were employed by the actor to deploy its custom malware on Ukrainian military devices.
Techniques Exploited for Execution of Attacks
The actor relies on various techniques such as spear-phishing to gain initial access.
Nigerian scams and spoofing attacks are frequently used by cyber attackers, including adversary groups who want to infiltrate networks remotely without revealing their intent. This technique can be employed to trick users into divulging sensitive information.
Spear phishing is often used by adversary groups to bypass security defenses. This technique is employed to trick users into divulging sensitive information which helps to execute further attacks and exploits.
Tactics, Techniques, and Procedures (TTPs) are an extremely effective method of achieving the goals of your attack vector.
Protecting yourself against such sophisticated attack methods can seem daunting, however it is essential not to be caught off guard.
The consequences range from data theft and loss, through the exploitation of sensitive information or complete takeover of network systems.
A successful breach of a major organization’s secure system could result in huge financial gains, both for your hackers and their employers if sold on the black market.
Initial Access
Spear phishing is often used by adversary groups to bypass security defenses. This technique is employed to trick users into divulging sensitive information which helps to execute further attacks and exploits.
It’s because they know exactly which companies are using the most popular software, and therefore use these platforms when launching a targeted attack.
Recommendations
Based on the threat report, several recommendations can be made for improving cybersecurity posture:
Monitor activity from known adversary groups, such as Storm-1837.
Implementing robust security controls and protocols helps protect an organization’s sensitive assets in these advanced threats. Regularly updating your software packages is also recommended to prevent exploitation by zero-day vulnerabilities, or through the exploitation of newly discovered vulnerabilities and bugs.
Regular maintenance and monitoring can identify vulnerabilities. An organization should have multiple layers of protection against their threat vector as well. Firewalls and intrusion detection systems are some examples.
Cybersecurity Tips:
One of the most effective methods in preventing cyber security threats is to implement robust security measures such as multi factor authentication, two factor login, firewalls and more.
Cyber Security Awareness Month
is recognized internationally as an occasion to increase security measures in protecting sensitive data that could provide the advantage over competitors.

In the ever-evolving landscape of cybersecurity, staying ahead of emerging threats is crucial for protecting sensitive information and maintaining operational integrity. A recent threat report published by CyberHunter_NL on February 12, 2025, highlights a critical vulnerability in Ivanti Connect Secure that is being actively exploited to deploy an advanced malware variant known as SPAWNCHIMERA.
The vulnerability, identified as CVE-2025-0282, is a stack-based buffer overflow that allows remote unauthenticated attackers to execute arbitrary code on vulnerable devices. This flaw was disclosed in January 2025 and has since been targeted by multiple threat actors, underscoring the urgency for organizations to take immediate action.
SPAWNCHIMERA malware is particularly concerning due to its advanced capabilities and stealthy nature. Once deployed, it can compromise systems, exfiltrate data, and potentially disrupt critical operations. The malware’s ability to evade detection makes it a formidable adversary, requiring robust security measures to mitigate the risk.
The threat report provides valuable insights into the tactics, techniques, and procedures (TTPs) employed by the attackers. Understanding these TTPs is essential for developing effective countermeasures. For instance, the report details how the vulnerability is exploited through remote code execution, allowing attackers to gain unauthorized access to systems. This information can guide security teams in identifying potential indicators of compromise (IOCs) and implementing proactive defenses.
One of the key recommendations from the report is to apply the latest patches and updates provided by Ivanti. Patching vulnerabilities promptly is a fundamental aspect of cybersecurity hygiene and can significantly reduce the risk of exploitation. Organizations should also consider deploying intrusion detection systems (IDS) and intrusion prevention systems (IPS) to monitor network traffic for suspicious activities.
Additionally, the report emphasizes the importance of regular security audits and vulnerability assessments. These practices help identify weaknesses in the system before they can be exploited by malicious actors. Conducting thorough risk assessments allows organizations to prioritize their security efforts effectively.
Another critical recommendation is to implement multi-factor authentication (MFA) for all user accounts. MFA adds an extra layer of security by requiring multiple forms of verification, making it more difficult for attackers to gain unauthorized access even if they manage to exploit a vulnerability.
Network segmentation is also highlighted as a best practice. By isolating different parts of the network, organizations can limit the lateral movement of malware and contain potential breaches. This approach helps in minimizing the impact of an attack and provides more time for security teams to respond effectively.
The report also advises on the importance of employee training and awareness programs. Human error remains one of the leading causes of security breaches, and educating employees about cyber threats can significantly enhance an organization’s overall security posture. Regular training sessions should cover topics such as phishing attacks, password management, and safe browsing practices.
In conclusion, the threat report on SPAWNCHIMERA malware serves as a stark reminder of the persistent dangers in the cybersecurity landscape. By understanding the TTPs employed by attackers and implementing robust security measures, organizations can better protect themselves against this advanced malware variant. Patching vulnerabilities, deploying IDS/IPS systems, conducting regular audits, implementing MFA, segmenting networks, and educating employees are all essential steps in mitigating the risk posed by SPAWNCHIMERA.
