ExifTool — Metadata Analysis & Manipulation

●​ Purpose: To view, edit, copy, or remove metadata from images or


other files.
●​ Why: Metadata can reveal important forensic info like device used,
location, timestamps, authorship, etc.
●​ Use Case: Checking if an image has GPS coordinates or camera info,
removing metadata for privacy.

Commands
1.Install ExifTool (if not installed):​
​
sudo apt install libimage-exiftool-perl

2.Read all metadata from an image:​


​
exiftool image.jpg
3.Read specific tags:​
​
exiftool -Make -Model -DateTimeOriginal image.jpg

4.Write metadata (e.g., add artist name):​


​
exiftool -Artist="Your Name" image.jpg

5.Delete specific metadata (GPS):​


​
exiftool -GPSLatitude= -GPSLongitude= image.jpg

6.Remove all metadata:​


​
exiftool -overwrite_original -all= image.jpg

7.Copy metadata from one file to another:​


​
exiftool -tagsfromfile source.jpg destination.jpg
strings — Extract Readable Text from Binaries

●​ Purpose: To pull out human-readable strings from executable or


binary files.
●​ Why: You can find hidden messages, passwords, URLs, or
suspicious content inside compiled programs or malware.
●​ Use Case: Discovering URLs or credentials in a suspicious .exe or
.bin file.

1.Basic usage:​
​
strings /bin/ls
2.Set minimum length:​
​
strings -n 8 /bin/ls

3.Show file offsets:​


​
strings -td /bin/ls | head -n 10 # Decimal

strings -tx /bin/ls | head -n 10 # Hex


4.Search for specific text:

​
strings suspicious_file | grep "http://"

binwalk — Analyze Firmware or Binary Files

●​ Purpose: To detect and extract embedded files


or data inside firmware images.
●​ Why: Useful in reverse engineering firmware
to understand how a device works or find
vulnerabilities.
●​ Use Case: Extracting images, file systems, or
configs from an IoT firmware .bin file.
dirb — Discover Hidden Web Directories

●​ Purpose: To brute-force and find hidden/unlinked files or


directories on a website.
●​ Why: These hidden paths could expose sensitive data (admin
panels, backups, config files, etc.).
●​ Use Case: Finding a forgotten /admin_backup/ folder that
exposes credentials.
