NSM Keyless Recovery v2.0.0 – Public Release

NSM Keyless Recovery v2.0.0 - Public Release

This is the first public release of NSM Keyless Recovery.

This tool is not a ransomware decryptor. It attempts deterministic, donorless structural recovery using only information that survives in files affected by NSM ransomware (.nsm extension).

The original .nsm files are never modified.

IMPORTANT: Please download one of the Public EN/KR ZIP files listed below under Assets.
The automatically generated GitHub Source code (zip) and Source code (tar.gz) archives are NOT the recovery program.

Recovery categories

Current recovery/analysis paths include:

• HWP, HWPX, DOCX, XLSX, PPTX
• PDF
• ZIP
• JPG/JPEG, PNG, TIF/TIFF, PSD
• MP3
• WMV/ASF, MP4, MOV, MTS/M2TS/TS
• limited generic structural carving

Support is conditional. Not every file of a listed type can be recovered.

Important

• Keep the original encrypted .nsm files.
• NO_SAFE_RECOVERY means the public build does not have enough reliable data to reconstruct the file safely; it is not the same as a software error.
• Recovered files may be partial and may be missing metadata or short damaged regions.
• Run recovery work on an isolated/safe Windows system when possible.
• This software does not remove ransomware or recover the attacker's encryption key.

Technical review and feedback are welcome. Please do not post confidential victim files in public issues.
