HIPAA Compliance Checklist for 2025
A call from your “bank” asking to verify account details may sound harmless, but it could be a trap. This technique, known as vishing (voice phishing), is one of the fastest-growing SaaS security risks targeting individuals and enterprises alike.
According to the FBI’s Internet Crime Report 2023, vishing and related phishing scams led to losses exceeding $2.7 billion. Attackers exploit trust and urgency in phone calls, tricking victims into sharing credentials, financial data, or system access.
In this guide, we’ll break down what vishing is, explore real-world examples, and share practical prevention tips to help both individuals and enterprises stay safe.
TL;DR
- Vishing is voice-based phishing, where attackers use phone calls or voice messages to trick victims into revealing sensitive data.
- Common tactics include impersonation and urgency, such as fake bank alerts, tech support calls, government impersonation, or healthcare scams.
- Attacks exploit human trust and emotion, often bypassing traditional cybersecurity defenses like firewalls or antivirus software.
- Prevention relies on awareness and controls, including security drills, MFA, strict data-sharing policies, and verification protocols.
- CloudEagle.ai helps enterprises reduce vishing risks through automated access control, just-in-time permissions, centralized visibility, and audit-ready compliance tools.
What is Vishing?
Vishing is a social engineering attack where cybercriminals use phone calls or voice messages to trick victims into revealing sensitive information. Unlike other causes of data breaches, which relies on fraudulent emails, vishing leverages the human element of trust in voice communication.
Key characteristics of vishing attacks include:
- Impersonation of trusted entities such as banks, government agencies, or IT departments.
- Urgent requests for action, like verifying account details or resetting passwords immediately.
- Manipulation of emotions, often using fear or authority to pressure victims into compliance.
A common example is a scammer posing as a bank representative claiming suspicious activity on your account. The victim, fearing financial loss, may provide PINs or credentials without verifying the caller’s legitimacy.
Vishing is dangerous because it bypasses many traditional cybersecurity defenses. Firewalls or antivirus software can’t detect a malicious phone call, which makes awareness and vigilance the first line of defense.
How Does Vishing Work?
Vishing works by exploiting trust in voice communication and creating a false sense of urgency. Attackers use convincing scripts and spoofed numbers to appear legitimate. The process typically unfolds in a few key stages:
Target Identification
Attackers may collect information from common causes of data breaches, social media, or public records to personalize the call.
Impersonation of Authority
The scammer poses as a trusted entity, such as a bank officer, IT support, or government representative.
Psychological Manipulation
Victims are pressured with fear (fraud alerts, tax penalties) or incentives (refunds, prize winnings).
Extraction of Sensitive Data
The attacker requests account numbers, passwords, or verification codes under the guise of “helping.”
Exploitation
Once obtained, the information is used for identity theft, fraudulent transactions, or account takeovers.
In 2020, the Twitter Bitcoin Scam exposed how effective vishing can be. Hackers used phone calls to trick Twitter employees into revealing internal credentials.
With this access, they hijacked high-profile accounts (including Barack Obama and Elon Musk) to promote a cryptocurrency scam. The attackers made over $100,000 in Bitcoin within hours.
Common Examples of Vishing Attacks
Vishing attacks don’t follow a single pattern; they adapt depending on the victim and the attacker’s goal. Some scams target individuals for quick financial gain, while others aim at employees inside enterprises to breach sensitive systems.
1. Fake Bank or Credit Card Alerts
Banks often alert customers about suspicious activity via phone calls or messages. Vishing attackers exploit this by pretending to be bank representatives, urging urgent action. Unsuspecting victims may share sensitive account information, believing the call is legitimate.
These calls often leverage fear and urgency, instructing users to “verify” account numbers, authentication methods, or OTPs. Attackers may even spoof official bank numbers to appear authentic.
According to cybersecurity expert Kevin Mitnick,
“Humans are the weakest link in security, and vishing preys on that trust.”
Victims of fake bank alerts can face unauthorized transactions, identity theft, and financial loss. Awareness campaigns, multi-factor authentication, and verifying calls through official channels can help prevent such attacks.
2. Tech Support Scam Calls
Tech support scams have become a significant concern, with attackers impersonating legitimate companies to deceive victims. These scammers often claim that a computer has a virus or other issues and offer to fix them for a fee.
A notable statistic highlights the severity of this issue: In 2024, Forbes revealed that losses attributable to tech support scams amounted to $1.464 billion, marking a $500 million increase from 2023. This alarming rise underscores the growing sophistication and impact of such scams.
To protect oneself, it's crucial to be cautious of unsolicited tech support calls. Always verify the identity of the caller through official channels and avoid granting remote access to your computer unless you're certain of the person's legitimacy.
3. IRS or Government Agency Impersonation
Vishing attacks often exploit fear and urgency by impersonating government agencies, particularly tax authorities. Attackers call individuals claiming unpaid taxes or legal action, pressuring them to act immediately. Common tactics used by scammers include:
- Threatening legal consequences: Claiming lawsuits, arrest warrants, or heavy fines for non-compliance.
- Requesting immediate payment: Asking for payment via gift cards, wire transfers, or prepaid debit cards.
- Requesting sensitive personal data: Asking for Social Security numbers, bank details, or login credentials.
These calls are highly manipulative and can create panic, causing victims to act without verification. Always confirm through official government channels and never share personal information over unsolicited calls.
4. Healthcare and Insurance Scams
Vishing attackers often target individuals by impersonating healthcare providers, insurance companies, or Medicare representatives. They exploit the urgency of medical needs or insurance claims to trick victims into revealing sensitive information.
According to Brian Krebs, cybersecurity journalist,
“Healthcare data is gold to attackers because it’s permanent and uniquely identifies individuals.”
Attackers can sell this information on the dark web or use it for identity theft and fraudulent claims. This makes healthcare vishing one of the most damaging social engineering schemes.
Why is Vishing a Growing Threat?
Vishing attacks are on the rise as cybercriminals exploit the human element of security. Vishing targets users through voice calls, creating a sense of urgency and trust that emails often fail to replicate. The sophistication of these attacks makes even cautious employees vulnerable.
1. Increasing Sophistication of Scammers
Vishing attackers are becoming more advanced, using technology and psychological tricks to deceive victims. They often research targets to make their calls more convincing and tailored.
- Caller ID spoofing: Scammers manipulate phone numbers to appear as legitimate institutions.
- Social engineering scripts: Well-crafted scripts mimic authentic communication patterns.
- Automated calling systems: Bots increase call volume while maintaining personalized touches.
As these tactics evolve, enterprises and individuals must stay vigilant and implement strong verification practices.
2. Vulnerability of Remote and Hybrid Workers
Remote and hybrid work environments have expanded the attack surface for cybercriminals, making employees more susceptible to vishing attacks. Unlike traditional office settings, remote workers often use personal devices and unsecured networks, which can be easily exploited by attackers.
A significant concern is the increased reliance on voice communication for authentication and support. Attackers can impersonate IT support or HR departments, leading to unauthorized access to sensitive information.
For instance, in 2024, Cisco was a victim of a Vishing attack. The attacker convinced the employee to grant remote access, compromising the company's network,
3. Exploiting Human Fear and Urgency
Vishers often manipulate emotions like fear, anxiety, or urgency to trick victims into divulging sensitive information. They create a sense of immediate threat, making rational decision-making difficult.
Impersonating Authorities
Attackers may pose as IRS agents, bank officials, or law enforcement, pressuring targets to act quickly without verification.
Urgent Security Alerts
Fake warnings about account breaches or overdue payments prompt hasty responses, increasing the success rate of attacks.
Time-Sensitive Consequences
Vishing scripts often threaten severe consequences, like account suspension or legal action, exploiting natural human reactions to urgency.
Vishing Prevention Best Practices for Enterprises
Enterprises face rising risks from vishing attacks targeting employees, customers, and partners. Implementing structured prevention measures can reduce exposure, strengthen security awareness, and protect sensitive data from social engineering exploits.
1. Regular Security Drills and Awareness Campaigns
Regular security drills and awareness campaigns are essential in preparing employees to recognize and respond effectively to vishing attacks. These initiatives help cultivate a security-conscious culture within the organization.
According to a 2025 report by KnowBe4, organizations that conducted regular simulated phishing exercises saw a significant reduction in phishing susceptibility. The report revealed that the global Phish-prone Percentage (PPP) decreased by 86% over 12 months of security training.
This statistic underscores the effectiveness of continuous training and simulation in enhancing employee awareness and reducing the risk of successful vishing attacks.
2. Implementing Multi-Factor Authentication (MFA)
Multi-Factor Authentication (MFA) adds an extra layer of security, ensuring that even if attackers gain credentials, unauthorized access is prevented. By combining something users know (password), something they have (security token), or something they are (biometric), enterprises drastically reduce the risk of vishing-related breaches.
Layered Protection
MFA requires multiple verification steps, making it harder for attackers to compromise accounts. This protects sensitive systems from unauthorized access.
Adaptive Authentication
Organizations can apply MFA selectively for high-risk actions or users, improving usability without sacrificing security.
Integration With Existing Systems
MFA can be integrated with enterprise applications, VPNs, and cloud platforms to create consistent security coverage.
User Education
Employees should understand how MFA works and why it’s critical, reducing resistance and encouraging proper usage.
Implementing MFA is especially effective against vishing because attackers often rely on stolen credentials. MFA ensures that a password alone is insufficient, significantly lowering the success rate of such attacks.
3. Limiting Sensitive Data Sharing Over Calls
Enterprises must establish strict policies to prevent employees from sharing sensitive information over phone calls. Attackers often impersonate trusted entities, and restricting what can be disclosed reduces the risk of successful vishing attempts. Here are some best practices:
- Verification Protocols: Always verify the caller’s identity using official channels before sharing any confidential data.
- Role-Based Restrictions: Only employees with specific roles should have access to sensitive information, limiting exposure.
- Predefined Scripts: Use approved scripts for phone interactions to avoid accidental disclosure of critical information.
- Employee Training: Regularly train staff on recognizing social engineering tactics and understanding what information is off-limits.
Limiting sensitive data sharing over calls strengthens an enterprise’s overall security posture. When combined with other preventive measures like MFA, the likelihood of vishing success is significantly reduced.
