In the ever-evolving world of cyber threats, ransomware attacks continue to be a significant concern for governments and organizations across the globe. Recently, the ThreatMon Threat Intelligence Team detected a fresh wave of ransomware activity attributed to the “Devman” group. This cybercriminal group has reportedly added a new victim to its growing list: NSSF Kenya. The attack, which occurred on June 7, 2025, involved the deployment of the malicious nssf.zip file, along with a detailed write-up hosted in nssfwriteup.html. This raises crucial questions about the ongoing impact of ransomware in critical sectors, especially those that handle sensitive financial and social security data.

The ThreatMon Threat Intelligence team has uncovered alarming activity related to the “Devman” ransomware group, which has recently attacked NSSF Kenya, one of the most vital institutions in the country. The attack was traced to June 7, 2025, at precisely 10:52:33 UTC. According to the post, the ransomware group used a malicious zip file (nssf.zip) along with a detailed explanation or “write-up” in an HTML document (nssfwriteup.html) as part of their attack strategy.
This post was shared publicly on social media by the ThreatMon platform, which specializes in monitoring and detecting ransomware activities. It revealed that the Devman group, a known threat actor, continues to target institutions with valuable data, as evidenced by this attack on the National Social Security Fund (NSSF) of Kenya. This attack could have far-reaching consequences, affecting not only the operational capacity of NSSF but also the financial and social security data of millions of Kenyans. While the specifics of the attack are still being analyzed, this serves as a critical reminder of the growing threat of ransomware in the public sector.
What Undercode Say:
Ransomware groups like “Devman” are becoming increasingly sophisticated, targeting high-profile institutions that manage sensitive data. In this particular case, the attack on NSSF Kenya is a reminder of the vulnerabilities present in critical infrastructure, especially in developing countries. Ransomware attacks have moved beyond just corporate targets; they are now impacting government entities and essential services.
The use of a zip file in this attack suggests the exploitation of a simple yet effective delivery method, one that often bypasses traditional email security filters. The HTML write-up accompanying the attack likely provided the attackers with the ability to communicate their demands clearly and to further spread their malicious payload.
Given the growing scale of cyberattacks targeting social security and financial institutions worldwide, there is a pressing need for stronger security protocols within these sectors. In the face of evolving ransomware tactics, it is critical for organizations like NSSF Kenya to invest in more advanced cybersecurity measures to prevent such attacks from succeeding. This may include implementing real-time threat monitoring systems, ensuring regular data backups, and educating staff about potential phishing and malware threats.
As more organizations face such targeted cyberattacks, the implications extend beyond the immediate financial loss. These breaches can erode public trust, disrupt essential services, and lead to long-term reputational damage. Therefore, as cybersecurity becomes an even more crucial component of organizational strategy, it’s important to recognize the increasing threat posed by ransomware groups like Devman and others operating in the dark web.

Prediction 📈
The increasing trend of ransomware attacks targeting government and financial institutions is likely to continue, with cybercriminals adopting more sophisticated techniques. As public and private sectors alike are targeted, there will be a rising demand for robust cybersecurity frameworks, more advanced threat detection systems, and enhanced employee awareness to mitigate such risks. Furthermore, as ransomware attacks continue to evolve, it’s expected that ransom demands will increase, leading to a higher financial impact on victims and, potentially, a broader international response to combat this growing threat.
