A new wave of cyberattacks has emerged, targeting a wide range of organizations globally. These attacks are exploiting a previously unknown vulnerability in Microsoft Windows, known as a zero-day flaw, to infiltrate systems for espionage, data theft, and even cryptocurrency theft. This vulnerability, tracked as ZDI-CAN-25373 by Trend Micro researchers, has been actively exploited since 2017 by various state-sponsored groups. The attacks are both financially motivated and focused on espionage, affecting sectors such as government, finance, telecom, energy, and military. This article dives deep into the details of this ongoing campaign and the vulnerability at its core.

Cybercriminals, working for at least six nation-states, have been exploiting a zero-day vulnerability in Microsoft Windows, identified as ZDI-CAN-25373. This flaw allows attackers to execute malicious commands through shortcut (.lnk) files, which are disguised in a way that the Windows operating system fails to display their true nature. According to Trend Micro researchers, this vulnerability has been used for espionage, data theft, and the theft of cryptocurrencies.
Since 2017, multiple state-sponsored groups, particularly from North Korea, have been using this exploit to target governments, think tanks, and organizations in critical sectors such as finance, military, and energy. Researchers discovered the flaw in September and reported it to Microsoft. However, the vulnerability has not yet received a Common Vulnerability Exposure (CVE) identifier, and Microsoft has yet to commit to a fix.
Trend Micro’s report indicates that at least 300 organizations have been affected, with thousands of devices compromised worldwide. The majority of attacks have been traced back to North Korean groups, specifically APT43 and APT37, with significant involvement from cybercriminals in Russia, China, Iran, and other countries. These state-sponsored attacks are often financially motivated, particularly in the case of North Korea, where cryptocurrency theft appears to be a primary objective.
One of the unique aspects of this exploit is the novel malware payload. Attackers use cleverly disguised shortcut files to make malicious code appear harmless, taking advantage of how Windows displays files. The flaw has been difficult to patch, and Microsoft’s response has been criticized, with many experts suggesting that the company’s reluctance to address the issue highlights a broader problem with its handling of zero-day vulnerabilities.
What Undercode Says:
The exploitation of ZDI-CAN-25373 reveals several key points about modern cyber warfare and the evolving methods used by state-sponsored cybercriminals. The use of zero-day vulnerabilities for espionage is not a new concept, but the scale and longevity of this exploit are particularly alarming. The fact that it has been active for over eight years before discovery suggests that many other undiscovered vulnerabilities are likely being exploited in similar ways.
What stands out in this case is the involvement of multiple nation-state actors, each using the same vulnerability for different purposes. North Korea, for example, has been particularly active, with a clear financial motivation behind many of its attacks, such as stealing cryptocurrency. This highlights the growing importance of digital currency as a target for cybercriminals, especially state-backed ones who are increasingly relying on cryptocurrency for funding.
The vulnerability’s impact is widespread, affecting not just government entities but also organizations in critical infrastructure sectors like energy and telecom. The fact that these organizations are prime targets for espionage demonstrates the continuing trend of cyberattacks as a strategic tool for national security.
Microsoft’s handling of the issue has sparked significant debate. The company has downplayed the severity of the problem, stating that the method of attack is limited in its practical use. However, experts argue that any vulnerability that is actively exploited in the wild should be treated with urgency. Furthermore, the fact that this zero-day has remained undetected for so long points to larger systemic issues in how software companies, including Microsoft, address security vulnerabilities. The company’s reluctance to implement a fix is frustrating, especially when the flaw’s exploitation is so widespread.
While Microsoft’s response may not immediately address the problem, the awareness raised by Trend Micro’s research is crucial for defenders. It provides them with the necessary information to protect their systems, despite the lack of an official patch. Additionally, this case underscores the need for greater collaboration between cybersecurity researchers, tech companies, and governments to better detect and respond to zero-day vulnerabilities.
Fact Checker Results
1. Trend
- The flaw remains unpatched, and Microsoft’s stance on the issue is consistent with their past responses to similar vulnerabilities.
- Although Microsoft downplays the urgency, the long-term exploitation of this zero-day demonstrates a critical gap in cybersecurity that needs to be addressed by the company.
