Government Issues Warning Against Rising Vishing Threat: What You Need to Know

Last month, the government released a circular warning its employees of a sophisticated cybercrime— vishing. Short for voice+phishing, it’s a technique wherein a threat actor calls the victim over the phone and tries to trick her into clicking on malicious files or emails, which can then take one to a legitimate-looking website asking her to share personal information.

The Nature of Vishing Attacks

  1. Social Engineering Tactics
    • Unlike online scams that rely on malware, vishing uses social engineering, where the threat actor uses psychological tactics to trick the victim into taking a certain action.
    • Attackers often pretend to be authoritative figures, such as bank representatives or government officials, to exploit a sense of urgency.
  2. AI Amplification
    • Artificial intelligence enables attackers to imitate voices and mannerisms, making it easier to deceive victims.
  3. Common Techniques
    • Pre-recorded messages: Automated calls claim urgency related to financial matters, prompting victims to take actions.
    • Requesting sensitive information: Attackers ask for personal and sensitive information under various pretexts.
    • Pretending to be government officials: Claiming authority to extract information or compliance from victims.
    • Fear and urgency tactics: Creating a sense of urgency or threat to manipulate victims.
  4. Indicators of Vishing Attacks
    • Poor audio quality: Robotic-sounding voices or background noises indicate potential vishing attempts.
    • Unsolicited requests: Calls asking for sensitive information without prior context or validation.

Protection Measures

  • Independently verify callers’ identity: Avoid sharing personal information without confirming the caller’s authenticity.
  • Stay vigilant: Be aware of common vishing techniques and remain calm in urgent situations.
  • Screen calls: If in doubt, screen calls and avoid engaging with suspicious ones.
  • Do not confront the caller: Refrain from engaging with suspicious callers to avoid potential recording of sensitive information.

Response to Vishing Attacks

  • Contact authorities: Report any suspected vishing attempts to relevant authorities, such as banks and law enforcement.
  • Secure sensitive accounts: Change passwords and review accounts for any unauthorized activity.
  • Educate others: Spread awareness about vishing attacks to prevent future incidents.
