Vishing Protection Guide: How to Identify and Prevent Voice Phishing Attacks

What is Vishing?

Have you ever received a phone call or suspicious message from "Support" or "Customer Service"?

Vishing is a social engineering phone call. Scammers lure you to influence you to share your personal information and financial details. Scammers will ask for account numbers and passwords. One of the most popular phrases that a scammer might use is "Your account has been compromised". They will identify themselves as your bank or law enforcement. They will offer to help with installing one of their software. If this sounds familiar, it's probably malware and a scam.

Vishing can be any of the following types of messages: an email, text, phone call, or direct chat message that may appear from a trusted source, but be cautious because it's not.

As vishing propagates, it is getting easier for scammers to contact a higher amount of people by placing as many as a hundred calls at a time, using technology that can spoof the caller ID to display a legitimate-looking number.

How to Identify a Vishing Scam

Watch out for these common vishing tactics:

• Impersonation: The caller will identify themselves as the IRS, Medicare, or a Social Security Administrator
• Urgency: The caller will alert you with a sense of urgency, pressuring you to act immediately
• Information Requests: They'll ask for sensitive information such as your name, address, date of birth, social security number, and bank account information

Common Vishing Scenarios

1. Compromised Account Alerts - "Your account has been compromised and we need to verify your identity"
2. Tech Support Scams - "We've detected a virus on your computer and need remote access to fix it"
3. Government Agency Impersonation - "You owe back taxes and will be arrested unless you pay immediately"
4. Bank Verification Calls - "We need to verify recent transactions on your account"

How Can You Protect Yourself from Vishing Attacks?

Best Practices for Vishing Prevention

1. Ask for the caller's identity information and a call back number - Legitimate organizations will provide this information
2. Always avoid pressing buttons from responding to prompts - Don't engage with automated systems from unexpected calls
3. If the call feels obligated, hang up! - Trust your instincts
4. Don't pick up unknown calls - Caller IDs can be faked, meaning the caller is unknown. If this is the case, simply let it bypass to voicemail. Listen to the message and decide whether or not to call back
5. Remember: The IRS does NOT call you - They SEND you a certified letter

Additional Security Measures

• Enable multi-factor authentication (MFA) on all important accounts
• Use call filtering and blocking apps to screen potential scam calls
• Verify caller identity independently - Look up the official phone number yourself and call back
• Never install software at the request of an unsolicited caller
• Be skeptical of urgency - Legitimate organizations give you time to respond

How to Recover from a Vishing Attack

If you've fallen victim to a vishing attack, act immediately:

Immediate Steps

1. Contact Your Bank - If your credit or debit card information was mistakenly given in the process, contact your bank immediately and cancel your card—request a new one
2. Block Fraudulent Transactions - Ask about canceling the fraudulent transaction and blocking any future charges
3. Change Account Numbers - If your account information was compromised, you'll need to change your account number to ensure it doesn't get used on any future transactions
4. Monitor Your Credit - Place a fraud alert on your credit reports and monitor for suspicious activity
5. Report the Attack - File a report with the FTC at IdentityTheft.gov and your local law enforcement

Long-Term Recovery

• Change passwords for all affected accounts
• Enable credit monitoring services
• Review your credit reports regularly
• Document all communication related to the fraud
• Keep records of any financial losses for potential reimbursement

Frequently Asked Questions

Q: How is vishing different from phishing? A: Vishing uses voice calls or voicemail, while phishing typically uses email. Both are social engineering attacks designed to steal personal information.

Q: Can vishing attacks come through text messages? A: Yes, when vishing occurs through text messages, it's often called "smishing" (SMS phishing). The tactics are similar but use text messaging as the delivery method.

Q: Will my bank ever call and ask for my password? A: No, legitimate financial institutions will never call and ask for your full password, PIN, or account number. If someone calls claiming to be from your bank and asks for this information, it's a scam.

Q: How can I verify if a call is legitimate? A: Hang up and call the organization back using a phone number you find independently (not one provided by the caller). Look up the official number on the company's website or your account statements.

Q: What should I do if I think I've been targeted? A: Don't engage with the caller. Hang up immediately, report the number to the FTC, and if you provided any information, follow the recovery steps outlined above.
