What is Vishing (Voice Phishing)?

Yes, vishing is indeed a threat to your business. Vishing, a combination of 'voice' and 'phishing,' is a significant cybersecurity threat, manipulates phone communication to trick individuals into revealing sensitive business information. With Americans losing approximately $39.5 billion to vishing phone scams in 2022, it's clear this cyber threat demands attention. The sophisticated nature of these voice call phishing attacks, often involving deepfake technology or social engineering, highlights the urgent need for businesses to improve their defenses.

What is Vishing in Business?

Vishing in business targets individuals through phone calls, aiming to extract confidential information under the guise of legitimacy. Scammers, pretending to be bank officials or IT support, use voice manipulation and social engineering to exploit employees' trust, leading to potential financial loss or unauthorized access to company data.

How to Protect Your Business Against Vishing

To protect your business against vishing, businesses should adopt a multi-layered defense strategy. This includes:

  • Security Awareness Training: It's important to educate employees about vishing attacks, emphasizing the need to protect sensitive information. Training should cover how to recognize vishing attempts, the types of information at risk, and the potential impacts of a breach.
  • Use Vishing Simulation: Vishing simulation tools like Keepnet Labs’ Vishing Simulator in your cybersecurity training can greatly improve your employees’ readiness to vishing attacks. These tools simulate real-life vishing attacks, providing employees with practical experience in identifying and responding to phishing attempts via phone calls.
  • Two-Factor Authentication (2FA): Implementing 2FA adds an extra layer of security, making it significantly more challenging for attackers to gain unauthorized access through stolen credentials.
  • Harden Telephone Systems: Enhance your telephone system's security with caller ID verification, call blocking, and authentication features to deter attackers from spoofing phone numbers and impersonating legitimate contacts.
  • Multi-layered Security Measures: Protect sensitive data with encryption, secure storage solutions, and stringent access controls. This comprehensive approach makes it difficult for attackers to utilize any information gained from vishing.
  • Monitoring for Suspicious Activity: Keep a vigilant eye on telephone networks for any unusual activity that could indicate a vishing attempt, enabling early detection and response.
  • Educating on Caller Verification: Train users to verify the identity of callers before divulging any sensitive information. This step is vital as attackers often pose as credible sources to extract data.
  • Voice Biometrics: Utilize voice biometric technology to authenticate legitimate callers accurately, reducing the risk of impersonation and unauthorized access.
  • Secure VoIP Infrastructure: Ensure your VoIP systems are securely configured and shielded from unauthorized access and threats. Employing firewalls, encryption, and other protective measures is essential for defending against potential vulnerabilities.
  • Trusted Call-back Procedures: Implementing a verification process for callers can significantly enhance security. This approach involves verifying a caller's identity through a separate authentication process before any sensitive information is shared.
  • Strong Passwords and Authentication Practices: Adopting robust passwords combined with strong authentication methods helps ensure that only authorized individuals can access your systems. This might include using two-factor or multi-factor authentication for an added security layer.

What Should I Do if My Company Is the Victim of Vishing?

If your company becomes a victim of a vishing attack, acting as fast as possible and strategically is key to mitigating the impact:

  • Immediately report the incident to law enforcement and cybersecurity authorities to help track the perpetrators and alert them to the scam's tactics.
  • Assess and document the damage to understand the scope of the breach and identify compromised data and systems.
  • Secure your systems by changing any compromised credentials, including passwords and usernames, to prevent further unauthorized access.
  • Inform stakeholders about the breach, including what happened, the potential impact, and what is being done in response.
  • Review and update security protocols based on the attack analysis to strengthen defenses and prevent vishing attacks. This includes implementing regular data backups and enhancing employee training on cybersecurity awareness.
  • Monitor for further suspicious activity to catch any additional attempts early and to protect against the potential for multi-pronged attacks.
