Imposter scams have emerged as a dominant force in cyber-enabled fraud, eclipsing traditional phishing in terms of scale and impact. By leveraging social engineering tactics, spoofing technologies, and psychological manipulation, attackers deceive victims into divulging sensitive information or transferring funds.
Social Engineering Techniques:
- Exploiting human psychology: manipulating trust, fear, urgency, or perceived authority
- Caller ID spoofing: using VoIP tools to mimic legitimate numbers
- Phishing pages: cloning official sites using tools like HTTrack or Evilginx
- Email spoofing: exploiting SMTP vulnerabilities or using tools like SendEmail and SET Toolkit
- SMS spoofing: abusing compromised or unauthorized SMS gateways
- Impersonation on messaging platforms: replicating profile pictures and usernames on platforms like WhatsApp
- Deepfake voice and video: using advanced tools like ElevenLabs or Descript to mimic real individuals
Malware and Phishing Attacks
- Malware delivery: delivering spyware or remote access trojans (RATs) like njRAT or Quasar via malicious links
- Vishing (voice phishing): live callers deceiving victims into disclosing sensitive data like OTPs and PINs
