What youll learn: In this video, we delve into the emerging threat of CountLoader, a sophisticated malware loader being utilized by Russian ransomware groups. We'll explore its functionalities, the timeline of its deployment, and the broader implications for cybersecurity.

CountLoader has recently come to light as a significant tool in the arsenal of Russian ransomware gangs. Discovered on September 18, 2025, this malware loader is being used to deliver various post-exploitation tools, including Cobalt Strike and PureHVNC RAT. Its versatility is evident as it comes in three different versions: .NET, PowerShell, and JavaScript.

The malware has been observed targeting individuals in Ukraine through PDF-based phishing schemes that impersonate the National Police of Ukraine. Notably, the PowerShell variant has been previously flagged by Kaspersky for its distribution methods, which include deceptive tactics to trick users into installation.

Silent Push, a cybersecurity analysis firm, has highlighted that CountLoader serves as a conduit for other malicious tools, indicating a well-coordinated effort among ransomware affiliates, including those connected to LockBit and Black Basta. The JavaScript version stands out with its advanced capabilities, featuring multiple methods for file downloading and executing malware binaries.

The operational infrastructure of CountLoader is extensive, comprising over 20 unique domains, showcasing the complexity and reach of this threat. Additionally, the malware's ability to gather system information and maintain persistence on infected hosts raises significant concerns for cybersecurity professionals.

As the landscape of ransomware continues to evolve, the interconnected nature of these threat actors becomes increasingly apparent. The DomainTools Investigations team has noted that brand allegiance among these operators is weak, with human capital being the primary asset. This adaptability allows them to reorganize and respond to law enforcement actions effectively.

In light of these developments, organizations and individuals should remain vigilant. Implementing robust cybersecurity measures, including employee training on phishing awareness and maintaining updated security protocols, is crucial. Regular system audits and monitoring for unusual activity can also help mitigate the risks posed by such sophisticated malware.

CountLoader exemplifies the ongoing challenges in the cybersecurity landscape, highlighting the need for continuous vigilance and adaptation to emerging threats. Stay informed and prepared as we continue to monitor this evolving situation.
