Metadata extraction allows attackers to collect sensitive information from digital files.

EXIF (Exchangeable Image File Format) (Option A):

EXIF metadata contains camera details, GPS coordinates, timestamps, and software versions used to edit the file.

Attackers use tools like ExifTool to extract metadata for reconnaissance.

Penetration testers use OSINT (Open-Source Intelligence) tools to collect and analyze reconnaissance data.

Maltego (Option C):

Maltego is a powerful graph-based OSINT tool that integrates data from multiple sources (e.g., social media, DNS records, leaked credentials).

It automates data correlation and helps visualize connections.

Channel Scanning:

Wireless communications can be disrupted by identifying and interfering with the channels used by Wi-Fi networks.

Channel scanning allows the tester to map all active Wi-Fi channels, identify the target network, and determine possible jamming or interference strategies.

Why Not Other Options?

A (Port mirroring): This applies to wired network traffic duplication for monitoring purposes and is unrelated to wireless disruption.

B (Sidecar scanning): Not a relevant technique in the context of wireless disruption.

C (ARP poisoning): This targets Ethernet/IP communication in a local network, not wireless communication at the radio frequency level.

Using dig with a wordlist to identify subdomains is an effective method for subdomain enumeration. The command cat wordlist.txt | xargs -n 1 -I 'X' dig X.mydomain.com reads each line from wordlist.txt and performs a DNS lookup for each potential subdomain.

Command Breakdown:

cat wordlist.txt: Reads the contents of wordlist.txt, which contains a list of potential subdomains.

xargs -n 1 -I 'X': Takes each line from wordlist.txt and passes it to dig one at a time.

dig X.mydomain.com: Performs a DNS lookup for each subdomain.

Why This is the Best Choice:

Efficiency: xargs efficiently processes each line from the wordlist and passes it to dig for DNS resolution.

Automation: Automates the enumeration of subdomains, making it a practical choice for large lists.

Benefits:

Automates the process of subdomain enumeration using a wordlist.

Efficiently handles a large number of subdomains.

References from Pentesting Literature:

Subdomain enumeration is a critical part of the reconnaissance phase in penetration testing. Tools like dig and techniques involving wordlists are commonly discussed in penetration testing guides.

HTB write-ups often detail the use of similar commands for efficient subdomain enumeration.
