The Windows 64-bit memory dump is a proprietary diagnostic format developed by Microsoft for recording the state of system memory during a critical failure. System administrators and software developers utilize these files to perform post-mortem debugging of kernel-level crashes, driver conflicts, and application instability. Although the format itself is safe, these captures often contain sensitive information such as plaintext credentials or encryption keys, necessitating controlled access to protect data privacy.

How to validate .dmp files in Python
Python

"""Check if file is a valid DMP by magic bytes."""
signature = bytes([0xA1, 0xB2, 0xC3, 0xD4])
with open(file_path, "rb") as f:

How to validate .dmp files in Node.js
Node.js

const signature = Buffer.from([0xA1, 0xB2, 0xC3, 0xD4]);
return buffer.subarray(0, 4).equals(signature);
}
Go

if len(data) < 4 {
return false
}
return bytes.Equal(data[:4], signature)
