Day 5 - “A Christmas DOScovery: Tapes of Yule-tide Past”
The primary objectives of this challenge were :
•How to navigate an unfamiliar legacy system
•Learn about DOS and its connection to its contemporary, the Windows Command Prompt
•Significance of file signatures and magic bytes in data recovery and file system analysis
In this task we had to restore a backup file, we were provided with some of the commonly used Dos commands and utilities.
When we tried to access the backup file we found out there was a file signature problem and we fixed the file signature and restored the backup file.
File signatures, commonly referred to as "magic bytes", are specific byte sequences at the beginning of a file that identify or verify its content type and format. These bytes often have corresponding ASCII characters, allowing for easier human readability when inspected. The identification process helps software applications quickly determine whether a file is in a format they can handle, aiding operational functionality and security measures.
In cyber security, file signatures are crucial for identifying file types and formats. You'll encounter them in malware analysis, incident response, network traffic inspection, web security checks, and forensics.
Here is the walkthrough of Day 5.
