New Research Finds Exploitable Vulnerability in DOS-to-NT Path Conversion Process

New research has found that threat actors could exploit the path conversion process from DOS to NT to achieve rootkit-like capabilities to conceal and impersonate files, directories, and processes. This has significant implications for the security of . It highlights the need for greater awareness of potential risks.

What is the DOS-to-NT Path Conversion Process?

The DOS-to-NT Path Conversion Process is a mechanism that is used to translate file and folder paths between the legacy MS-DOS file system and the NTFS file system. This process is necessary to ensure that older software, which still relies on the outdated MS-DOS file system, can still function on newer that use the NTFS file system.

How does the Work?

According to SafeBreach researcher Or Yair, when a user executes a function with a path argument in Windows, the DOS path at which the file or folder exists is converted to an NT path. During this process, a can be exploited, enabling an attacker to impersonate files, directories, and processes and conceal them from detection.

Implications of the :

The discovered by SafeBreach has significant implications for the security of Windows . It highlights the need for greater awareness of potential risks and the importance of implementing effective security measures to protect against such threats.

The discovery of the in the DOS-to-NT Path Conversion Process reminds us of the constant need for vigilance in cybersecurity. As always, individuals and organizations must remain informed of potential risks and take steps to protect themselves against these threats.
