Vishing
Testing Resilience Against Voice Phishing Attacks
Can your employees detect voice-based manipulation? Vishing (voice phishing) is a social engineering method where attackers impersonate IT staff, managers, banks, or institutions to extract information. Vishing tests help assess how vulnerable your organization is to such threats while raising employee awareness and improving their ability to recognize manipulation.
What are the benefits of Vishing Tests?
Identifying weaknesses in communication protocols
– we assess whether employees disclose confidential information over the phone to unauthorized individuals.
Preventing identity theft and financial fraud
– vishing is used to steal identities, hijack accounts, or trick employees into transferring funds.
Raising threat awareness
– employees learn to recognize voice scams and apply proper response procedures.
Strengthening security policies
– we provide recommendations on verifying caller identity and managing suspicious calls.
What is Vishing and how does it work?
Vishing (voice phishing) is a technique in which attackers use phone calls to manipulate victims into revealing sensitive information or taking unauthorized actions.
During vishing tests, we assess your organization’s exposure to:
- IT impersonation attacks – attackers pose as administrators and ask employees to change passwords, provide 2FA codes, or run malicious software.
- Fake financial requests – scammers impersonate CFOs, accounting staff, or vendors requesting urgent transfers or account details.
- Call center and customer service attacks – we test whether frontline staff verify caller identity before sharing information.
- Password reset fraud – we assess whether attackers can trick employees into resetting passwords and compromising accounts.
- Psychological manipulation – we analyze how employees react to time pressure, threats, or emotional triggers used by fraudsters.
Vishing tests help eliminate both human and procedural vulnerabilities—before attackers can exploit them.
Tools and Techniques We Use
Our vishing simulations employ advanced social engineering methods and organizational vulnerability assessment tools:
- Phone number spoofing – simulating calls from internal numbers, banks, or IT service providers.
- Voice AI & deepfake testing – assessing whether employees can distinguish synthetic voices from real ones.
- A/B attack scenarios – varying test cases to evaluate manipulation effectiveness and staff resilience.
- Call recording & behavior analysis – capturing employee responses and providing actionable recommendations.
- Post-test awareness workshops – training sessions to help staff identify vishing and learn defensive strategies.
Our testing aligns with NIST, ISO 27001, and leading social engineering protection practices.
Frequently Asked Questions
Are vishing tests legal?
Yes. All tests are conducted with organizational consent and follow an agreed scenario. The goal is to educate employees—not to penalize them.
How often should vishing tests be conducted?
We recommend conducting tests at least quarterly, especially for finance, HR, and IT departments or staff with access to sensitive data.
Do the tests involve call recording?
Yes. Calls are recorded for analysis and training purposes, with access restricted to the organization’s designated security contact.
What procedures help protect against vishing?
We recommend implementing call-back verification, where callers are validated via a separate communication channel, and regular staff training on vishing awareness.
