About Remote Code Execution - Windows LNK File (CVE-2025-9491) vulnerability

About Remote Code Execution – Windows LNK File (CVE-2025-9491) vulnerability. A vulnerability in the Microsoft Windows shortcut (.LNK) handling mechanism allows malicious command-line arguments to be hidden in the Target field using whitespace characters, making them invisible to standard tools. Opening such an LNK file may lead to arbitrary code execution.

🔻 Peter Girnus, an expert at Trend Micro, notified Microsoft about the vulnerability on September 20, 2024, but they decided not to fix it. 🤷‍♂️ On August 26, 2025, this 0-day vulnerability (ZDI-CAN-25373) was assigned the identifier CVE-2025-9491.

👾 On March 18, 2025, Trend Micro reported that this vulnerability was exploited in APT attacks, and on October 30, Arctic Wolf Labs confirmed it was used to deploy PlugX malware against Hungarian and Belgian diplomatic missions.

🛠 The method for modifying .LNK files is described in the Trend Micro report.
