Bloody Wolf, a mysterious hacking group of unknown provenance, has been attributed to a series of sophisticated cyber attacks targeting finance, government, and information technology (IT) sectors in Kyrgyzstan and Uzbekistan. The attackers, who have employed spear-phishing attacks to target entities in Kazakhstan and Russia, have demonstrated an impressive ability to weaponize low-cost, commercially available tools into regionally targeted cyber operations.
The use of Java-based loaders in these attacks highlights the importance of keeping software up-to-date and vigilant about potential security threats. The attackers' reliance on a bespoke JAR generator or template suggests that they are willing to invest time and resources into creating custom tools, further underscoring the sophistication of their operations.
By staying informed about emerging threats and adapting our security strategies accordingly, we can reduce the risk of falling victim to sophisticated exploits like those attributed to Bloody Wolf. The targeting of Kyrgyzstan and Uzbekistan using similar initial access techniques marks an expansion of Bloody Wolf's operations in the region. The attacks have been notable for incorporating geofencing restrictions, which cause requests originating outside of the country to be redirected to the legitimate data.egov[.]uz website.
This attack campaign serves as a stark reminder of the importance of robust cybersecurity measures and the need for continued vigilance in terms of potential security threats.

Bloody Wolf, a mysterious hacking group of unknown provenance, has been attributed to a series of sophisticated cyber attacks targeting finance, government, and information technology (IT) sectors in Kyrgyzstan and Uzbekistan. The attacks, which began as early as June 2025, have expanded to include the latter country, with Group-IB researchers Amirbek Kurbanov and Volen Kayo reporting that the threat actor has demonstrated an impressive ability to weaponize low-cost, commercially available tools into regionally targeted cyber operations.
The attackers, who have been identified as using spear-phishing attacks to target entities in Kazakhstan and Russia, have employed a combination of social engineering and Java-based loaders to deploy the NetSupport RAT. The Java Archive (JAR) files, which are built with Java 8, have been observed to be bespoke, suggesting that the attackers may be utilizing a custom JAR generator or template.
According to Group-IB, the NetSupport RAT payload is an old version of NetSupport Manager from October 2013. The attackers' approach has allowed them to maintain a strong foothold across the Central Asian threat landscape, exploiting trust in government institutions and leveraging simple JAR-based loaders to remain effective while keeping a low operational profile.
The targeting of Kyrgyzstan and Uzbekistan using similar initial access techniques marks an expansion of Bloody Wolf's operations in the region. The attacks have been notable for incorporating geofencing restrictions, which cause requests originating outside of the country to be redirected to the legitimate data.egov[.]uz website. Requests from within Uzbekistan have been found to trigger the download of the JAR file from an embedded link within the PDF attachment.
The use of Java-based loaders in these attacks highlights the importance of keeping software up-to-date and vigilant about potential security threats. The attackers' reliance on a bespoke JAR generator or template suggests that they are willing to invest time and resources into creating custom tools, further underscoring the sophistication of their operations.
Bloody Wolf's tactics, tactics, and procedures (TTPs) have been observed to follow a similar approach in both Kyrgyzstan and Uzbekistan. The message recipients are tricked into clicking on links that download malicious Java archive (JAR) loader files along with instructions to install Java Runtime. Once launched, the loader then proceeds to fetch the next-stage payload from infrastructure under the attacker's control, setting up persistence through various means.
The attackers have employed a range of techniques to ensure the success of their operations, including creating scheduled tasks, adding Windows Registry values, and dropping batch scripts to specific folders on the compromised system. These actions allow the attackers to maintain access to the compromised systems, even after initial malicious activity has ceased.
In conclusion, Bloody Wolf's sophisticated exploit is a stark reminder of the evolving nature of cyber threats. As threat actors continue to adapt and evolve their tactics, it is essential for organizations and individuals alike to remain vigilant and proactive in terms of security measures.
