# Vishing Red Flags Employees Miss on Live Calls

“This is IT. We detected a security problem with your account, and I need you to fix it before you lose access.”

The caller knows your name, your company, and the system you use. They sound competent. They may even know your manager or refer to a real support ticket. Then they ask you to open a link, approve a sign-in, share your screen, install a support tool, or confirm a payment while they stay on the phone.

You do not have to determine whether the caller is a criminal before protecting yourself. Use this sentence:

> “I don’t complete security-sensitive requests on an unexpected call. I’m going to end this call and verify it through our official channel.”

Then stop the requested action, end the call, and contact the person or function through a route you obtain independently. Do not use a number, link, transfer, QR code, or messaging account the caller supplied.

The rule works whether the voice belongs to a scammer, an AI system, or a legitimate colleague using an unusual number. Instead of deciding whether the person sounds real, ask: “Will this request survive our normal verification process?”

## What You’ll Learn

- Which behaviors matter more than caller ID, a familiar voice, or accurate personal details
- How authority, urgency, channel control, and callback resistance combine into a stronger warning pattern
- What to say when a caller claims to represent IT, an executive, a vendor, a bank, or another trusted party
- How to end the interaction and verify the request through a channel the caller does not control
- What to report immediately if you may already have shared information, granted access, approved a request, installed software, sent files, or moved money

## Stop Trying to Decide Whether the Voice Is Real

Employees are often told to listen for strange pauses, robotic phrasing, unnatural breathing, flat emotion, or background noise. Those details can make a call suspicious, but they cannot make it safe. [Deepfake detection tools face similar real-world limits](/blog/why-deepfake-detection-tools-fail-in-real-world-deployment), so neither human ears nor automated classifiers should make the verification decision alone. A real person can have a poor connection, use a script, speak with an unfamiliar cadence, or call from a noisy room. A synthetic voice can sound natural and familiar.

The [FBI has warned](https://www.ic3.gov/PSA/2025/PSA250515) that AI-generated audio may sound nearly identical to a known contact. Its May 2025 public service announcement described a specific campaign in which malicious actors used texts and AI-generated voice messages to impersonate senior US officials, establish rapport, and seek access to accounts. That warning does not mean every vishing call uses a live voice clone. It shows why recognizing a voice is no longer strong enough to authenticate a request.

In a controlled study of 4,100 US adults, [Heiding, Verdun, Lermen, and coauthors](https://arxiv.org/abs/2607.09970) found that caller persuasiveness predicted stated willingness to comply more strongly than whether the voice seemed human. General familiarity with AI did not improve detection accuracy. The study measured self-reported willingness in consumer-scam scenarios rather than completed fraud or employee failure rates. Its results suggest that persuasiveness can matter more than an artificial-sounding voice.

Caller ID is weak evidence for the same reason. Numbers and display names can be spoofed. A caller can also use a legitimate service, a compromised account, or a number that resembles an internal extension. Accurate details do not solve the problem either. Job titles, managers, vendors, technology platforms, office locations, travel plans, and support processes may be public, purchased, stolen, or learned during earlier calls.

Audio artifacts, caller ID, and personal knowledge may raise suspicion, but they cannot establish identity. Evaluate the request instead:

- Did you expect the contact?
- Is the caller asking for information, access, approval, software, files, or money?
- Are they controlling the contact route and asking you to bypass normal procedure?
- Can you end the call and verify independently without resistance?

You do not need to outsmart a voice clone. You need a verification process the caller cannot control.

## How a Vishing Call Escalates While You Are Still Talking

Vishing is voice phishing: social engineering conducted by phone or another voice channel. The call may feel like an ordinary workplace interaction because the attacker builds it from familiar parts.

A typical call develops through four phases:

1. **Opening contact:** The caller creates a plausible reason for reaching you.
2. **Trust building:** They use authority, accurate details, helpfulness, or small requests to lower your guard.
3. **Pressure:** They introduce urgency, secrecy, embarrassment, or a supposed exception to normal procedure.
4. **Risky action:** They steer you toward credentials, MFA, screen sharing, software, files, a payment, or another channel they control.

Not every attack races through these phases. [Google Threat Intelligence Group reported](https://cloud.google.com/blog/topics/threat-intelligence/targeted-campaign-us-law-firms) one Silent Ransom Group incident in which the same target received five calls over three days. A patient caller can gather context, normalize the interaction, and make the final request feel like a continuation of legitimate work.

Look for clusters. One unfamiliar number proves little. An unexpected personal-cell call from “IT,” followed by a mandatory account change, an attacker-supplied login page, live coaching through MFA, and resistance to an independent callback is a much stronger warning pattern.

## Opening Red Flags: Unexpected Contact and Borrowed Authority

During the opening, the caller tries to turn an unverified identity into an accepted role. Two signals matter immediately: you did not expect the contact, and the caller wants their claimed authority to substitute for verification.

### Red flag 1: The contact is unexpected or off-channel

**What the caller may say:** “I’m following up on your support issue.” “We need to complete a security update.” “Your account was flagged.” “I was asked to call your mobile because you are not responding on Teams.”

**What the tactic is doing:** The caller is giving the interruption a work-shaped explanation. Reaching a personal phone can make the interaction feel urgent or privileged. Referring to a ticket or current issue can make the call feel expected even when you did not initiate it.

Google’s Threat Intelligence Group documented this pattern in its reporting on [BlackFile, also tracked as UNC6671](https://cloud.google.com/blog/topics/threat-intelligence/blackfile-vishing-extortion-operation). Callers targeted employees’ personal mobile phones, impersonated IT or help-desk staff, and used mandatory passkey or MFA updates as pretexts. GTIG said the group had targeted dozens of organizations across North America, Australia, and the UK. “Targeted” does not mean every organization was compromised, but it shows how deliberately attackers can select the contact route and story.

An unfamiliar number alone is not proof of fraud. The important mismatch is between the contact and your known workflow. Did you open a ticket? Does IT normally call personal phones? Is an account migration actually scheduled? Would this change normally begin with an unsolicited call?

**What you can say:**

> “Please give me the ticket or reference number. I’ll end this call and contact the help desk through our internal directory.”

A reference number gives your real support team context but does not authenticate the caller. A plausible number should not persuade you to continue.

### Red flag 2: The caller borrows authority

**What the caller may say:** “I’m calling from security.” “The CEO needs this handled before the board meeting.” “This is the fraud department.” “I’m working with law enforcement.” “Your account manager escalated this to me.”

**What the tactic is doing:** Titles and institutions discourage ordinary questions. The caller wants you to treat rank, expertise, or urgency as proof of identity. They may sound calm and professional rather than aggressive. Quiet authority can be more persuasive because it resembles a routine workplace interaction.

The FBI’s senior-official warning illustrates why recognition and status are not verification. The campaign used the identities of senior officials to build rapport before trying to move targets toward account access. The same principle applies at work: a familiar name may be part of the pretext.

**What you can say:**

> “I need to verify requests of this type through our normal process. I’ll contact the appropriate office using the directory.”

You do not need to accuse the caller of lying. State the process, end the interaction, and use the process.

## Trust-Building Red Flags: Accurate Details, Helpfulness, and Small Commitments

Effective vishing calls often begin with information and assistance. The caller may know enough to sound like an insider, help with a minor problem, or ask questions that seem harmless.

### Red flag 3: Accurate details are presented as proof

**What the caller may say:** “I’m looking at the ticket you opened yesterday.” “Your manager, Elena, approved the change.” “You use Okta for this account, correct?” “I know you are traveling, so we need to fix this before your next login.”

**What the tactic is doing:** Specificity creates credibility. Yet the caller may have gathered details from company websites, social media, data brokers, stolen email, previous conversations, or a compromised colleague. A real ticket number could also come from an earlier breach or from someone who called the help desk to learn its procedures.

Mandiant’s technical analysis, [“Hello, Operator?”](https://cloud.google.com/blog/topics/threat-intelligence/technical-analysis-vishing-threats), describes attackers researching employees, applications, phone numbers, organizational structures, and support processes before calling. Good preparation lets a false story contain true facts.

**What you can say:**

> “I’m not going to confirm additional information on an inbound call. I’ll check the request through the official ticketing system.”

Do not reward accurate knowledge with more data. Move the request into the system that owns the information.

### Red flag 4: “Verification” asks you to authenticate the attacker

**What the caller may say:** “I need to verify you before I can secure the account.” “Read me the six-digit code.” “Approve the test notification.” “Sign in while I check the error.” “Tell me which devices appear in your account.”

**What the tactic is doing:** The caller reverses the meaning of verification. Instead of proving their identity to you, they ask you to complete an action that may give them access. A password, one-time code, MFA approval, recovery answer, login session, or new device registration can help authenticate the attacker.

In the BlackFile workflow reported by GTIG, targets were directed to lookalike single sign-on pages. The [full Okta and MFA attack path](/blog/how-vishing-attacks-bypass-okta-mfa-defense-guide-for-2026) can include real-time credential and MFA relay, followed by registration of an attacker-controlled authentication factor. From the employee’s perspective, the steps could resemble a legitimate security update. The risk was in performing them inside a workflow initiated and controlled by the caller.

**What you can say:**

> “I can’t share credentials or codes, approve sign-ins, or change authentication during an unexpected call. I’ll contact security directly.”

If your organization has a formal verification method, follow it. Do not substitute a caller-designed “test.”

### Red flag 5: Small commitments keep escalating

**What the caller may say:** “First, just confirm your email address.” “Open the settings page so I can see which version you have.” “Join this meeting while I walk you through it.” “Since you are already there, click the support link.”

**What the tactic is doing:** Each step makes the next one feel smaller. Confirming a harmless fact can become opening a page, joining a meeting, sharing a screen, or approving a prompt. You may continue because stopping feels awkward after you have already cooperated.

The five-call Silent Ransom Group incident reported by GTIG shows that a slow, friendly approach can build trust across several days. The attacker does not need every action on the first contact.

**What you can say:**

> “I’m stopping here and checking the request through our approved channel before I do anything else.”

Past cooperation does not obligate you to continue. You can reset the interaction at any point.

## Pressure Red Flags: Urgency, Secrecy, and Procedure Bypass

Pressure narrows your attention. The caller wants the consequence of delay to feel more dangerous than the action they are requesting.

### Red flag 6: Urgency is used to remove thinking time

**What the caller may say:** “Your account will be disabled in ten minutes.” “We are actively seeing an attacker in your session.” “The payment must clear today.” “The client will lose access if you hang up.” “The executive is waiting.”

**What the tactic is doing:** A deadline turns verification into an apparent threat. You may fear being blamed for an outage, breach, missed payment, or angry executive. The caller can also use helpfulness or flattery: you are the only person who can fix this, and your quick action will save everyone trouble.

Urgency is not always loud. A calm caller can describe a severe consequence with the confidence of someone who expects immediate compliance. Focus on the requested exception regardless of the caller’s emotional volume.

**What you can say:**

> “Urgency does not remove our verification requirement. I’ll contact the official team now.”

If the issue is real, using the approved emergency route should help resolve it. If the caller says the official route is too slow, that is another warning.

### Red flag 7: Secrecy isolates you from a second opinion

**What the caller may say:** “Do not mention this in Teams.” “The investigation is confidential.” “Do not contact your manager yet.” “We cannot involve finance until the transaction is complete.” “You could compromise the case by telling security.”

**What the tactic is doing:** Isolation removes people and controls that could challenge the story. Secrecy may be framed as legal sensitivity, executive confidentiality, fraud prevention, or protection of your colleagues.

Some legitimate work is confidential. Confidentiality should still have an approved verification and authorization path. A caller does not get to invent a private process that excludes every person responsible for oversight.

**What you can say:**

> “I can’t act outside our approval process. I’ll verify this with the authorized contact.”

If the caller threatens consequences for reporting or checking, end the call immediately.

### Red flag 8: Normal procedure is treated as an obstacle

**What the caller may say:** “The portal is down.” “This is an exception.” “The ticket will be created afterward.” “The normal approver is unavailable.” “Security told us not to use the usual channel.”

**What the tactic is doing:** The caller explains why the organization’s normal controls supposedly cannot be used today, then turns one failed safeguard into a caller-selected alternative.

Real outages and exceptions happen. They should activate documented contingency procedures rather than a process invented during an unverified inbound call.

**What you can say:**

> “I’ll use our documented exception process and contact the responsible team independently.”

Do not debate whether the caller’s explanation is technically possible. If the request cannot survive the approved fallback process, you should not carry it out.

## The Ask: When the Call Moves Into Your Browser, Authenticator, or Wallet

Vishing is not limited to information spoken aloud. The phone call often acts as a control layer for an action elsewhere. The caller keeps you occupied while directing what you click, approve, install, copy, upload, or pay.

### Red flag 9: The caller controls the next channel

**What the caller may say:** “Use the link I just sent.” “Call the direct number on your screen.” “Scan this QR code.” “Move to Signal so we can continue securely.” “Join my Teams meeting.” “Open the private note before it expires.”

**What the tactic is doing:** The attacker is building a closed path. Every apparent verification step leads back to infrastructure or accounts they control. A professional-looking portal, familiar conferencing platform, or recognized messaging app does not make the route independent.

The FBI’s 2025 warning noted attempts to move targets to another messaging platform. GTIG’s Silent Ransom Group reporting described the use of familiar tools including Zoom, Microsoft Teams, Quick Assist, remote monitoring and management software, and self-destructing Privnote links. The tool itself may be legitimate. The risk comes from entering a session or following instructions initiated by an unverified caller.

**What you can say:**

> “I won’t use a link or contact route supplied during this call. I’ll open the official service myself.”

### Red flag 10: The request changes access, control, data, or money

Treat any of the following as a verification boundary. Stop before acting on an unexpected call.

| Caller’s request | Likely attacker objective | Safe employee response |
|---|---|---|
| Share a password, recovery answer, or one-time code | Take over an account or reset access | Do not disclose it. End the call and contact security through the approved route. |
| Approve an MFA push or “test” login | Authenticate the attacker’s session | Deny or leave it untouched and report the unexpected prompt. |
| Add a phone, passkey, authenticator, or device | Establish persistent attacker access | Make no authentication changes until the request is independently verified. |
| Open a link, scan a QR code, or sign in to a supplied page | Capture credentials, tokens, or payment details | Close or avoid the supplied route and open the official service independently. |
| Share your screen or start a remote-support session | Observe sensitive data or control the device | Decline and initiate support through the approved portal. |
| Install AnyDesk, another RMM tool, or a “security update” | Gain remote access and maintain control | Do not install it. Contact IT or security using a trusted channel. |
| Paste a command or run a script | Execute malware or change security settings | Stop. Do not run or repeat the command. Report the request. |
| Send, upload, or move files | Steal data or stage it for extortion | Do not transfer the files. Notify the data owner or security team. |
| Change bank details, send a wire, buy gift cards, or transfer crypto | Redirect funds | Use recorded contact details and the required second approver before any change. |
| Confirm personal, customer, or company information | Build a pretext, answer recovery questions, or enable fraud | Disclose no more information and report what was requested. |
| Keep the call secret or move to another messaging app | Isolate you and preserve attacker control | End the interaction and involve the authorized team. |

BlackFile and Silent Ransom Group illustrate different branches from the same kind of call. BlackFile used lookalike SSO pages, real-time credential and MFA relay, and new authentication-factor registration. The [Silent Ransom Group attack chain](/blog/silent-ransom-group-law-firms) used IT or security pretexts to lead targets toward screen sharing, remote-access tools, copied commands, file discovery, and theft. Do not collapse the two campaigns into one attack chain. The common lesson is that the caller’s end goal often exists outside the voice channel.

## The Clearest Test: What Happens When You Propose an Independent Callback

An independent callback is one of the strongest practical checks available during a suspicious call. It breaks the caller’s control of the conversation and contact route.

“Independent” is the critical word. Obtain the number or route from a source the caller did not provide, such as:

- Your company directory or approved help-desk portal
- A known internal contact already saved in your address book
- The official organization website or authenticated customer portal you open yourself
- The number on the back of a payment card or on a trusted statement
- A recorded vendor contact already held by procurement or finance

A transfer from the original caller is not independent. Neither is a “direct line,” link, QR code, callback button, email, or text they send during the call.

Watch how the caller responds when you propose ending the conversation. Warning signs include:

- Insisting that you remain connected while you complete the steps
- Claiming that hanging up will cancel protection or lock the account
- Telling you the official number cannot reach the right team
- Becoming angry when you mention a manager, second approver, IT, or security
- Offering to transfer you rather than letting you reconnect independently
- Repeating that there is no time for normal verification

Use a short statement:

> “Our policy requires me to end the call and verify independently. I’ll follow up through the official channel.”

Callback resistance is a strong warning, although it does not prove fraud. A legitimate caller may be impatient or unfamiliar with your procedure. A skilled attacker may calmly accept the callback because they have prepared another route. Obtain the contact details yourself and verify the request through the official process, even if you reconnect with someone who sounds convincing.

## What to Say During a Suspicious Call

You do not need a perfect explanation. You need a phrase you can remember while someone is applying pressure. State the policy, repeat it once if necessary, and end the call. Avoid debating the story or trying to catch the caller in a lie.

### General unexpected request

**Say:** “I don’t complete security-sensitive requests on an unexpected call. I’m going to verify this through our official channel.”

**Caller may respond:** “I only need thirty seconds, and then you can call anyone you want.”

**Repeat and exit:** “I need to verify first. I’m ending the call now.”

### IT or security call

**Say:** “Please give me the ticket number. I’ll contact the help desk through our internal directory.”

**Caller may respond:** “I am the escalation desk. If you call the main line, they will send you back to me.”

**Repeat and exit:** “That’s fine. I’ll start with the approved help-desk route.”

### Credential or MFA request

**Say:** “I can’t share passwords or codes, approve sign-ins, or change authentication over the phone. I’ll contact security directly.”

**Caller may respond:** “The prompt is only a test. Denying it will lock your account.”

**Repeat and exit:** “I won’t act on an unexpected authentication prompt. I’m contacting security now.”

### Executive request

**Say:** “I need to verify this through the normal approval process. I’ll call back using the number in our company directory.”

**Caller may respond:** “Do you really want to delay the CEO over a routine request?”

**Repeat and exit:** “The approval process applies regardless of seniority. I’ll follow it now.”

### Finance or payment request

**Say:** “I can’t change payment instructions or authorize funds from an inbound call. I’ll verify with the recorded contact and a second approver.”

**Caller may respond:** “The current contact is involved in the fraud, so you cannot call them.”

**Repeat and exit:** “I’ll escalate through our approved finance and fraud process.”

### Vendor or bank call

**Say:** “I’ll contact your organization using the number in our records or the official portal.”

**Caller may respond:** “That number will not reach this investigation team. Use my direct line.”

**Repeat and exit:** “I’ll begin with the official number and let them route me.”

### Screen sharing, remote support, or software installation

**Say:** “I don’t start remote sessions or install tools from an unsolicited call. I’ll open a support ticket through the approved portal.”

**Caller may respond:** “The portal is part of the outage. I need to fix it manually.”

**Repeat and exit:** “I’ll use our documented outage process. I’m ending the call.”

### Pressure to stay connected

**Say:** “I’m ending the call so I can verify independently.”

**Caller may respond:** “Do not hang up. You will interrupt the security process.”

**Repeat and exit:** “I will not continue on an unverified inbound call.”

### You already completed part of the request

**Say:** “I’m stopping here. I may have shared or approved something, and I’m contacting security now.”

**Caller may respond:** “Stopping halfway is what creates the risk. Let me finish securing it.”

**Repeat and exit:** “I’m not taking any more action. I’m reporting this now.”

The broken-record technique is simple: give the boundary, repeat it without adding new details, and leave. “Buying time” means taking control of the workflow long enough to stop, disconnect, and verify safely. It should not keep you in conversation with a suspected attacker.

## How to Verify the Request Safely After You Hang Up

Use a consistent process after any suspicious work call:

1. **Stop the requested action.** Do not enter another code, click another link, change a setting, send a file, or complete a payment.
2. **End the inbound interaction.** Do not keep the caller connected while you verify. If they contacted you through a meeting or messaging app, leave that session too.
3. **Find the official route independently.** Use your company directory, approved ticket portal, known contact, official website, authenticated portal, card, or trusted business record. Never use the caller’s number or link.
4. **Describe the caller and the full request.** Tell the official contact who called, what identity they claimed, what they knew, what they asked you to do, and which channels or tools they supplied.
5. **Involve the required approver.** Identity changes, access changes, payments, vendor bank updates, sensitive file transfers, and exceptional requests may require a manager, data owner, security team, or second financial approver.
6. **Report the original interaction.** Report it even if the request turns out to be legitimate. A culture in which careful verification is normal makes it easier for employees to act quickly when the call is malicious.

Do not treat hearing the same voice on a callback as confirmation. The security comes from using a trusted route and the official process behind it.

## If You Already Shared, Clicked, Approved, Installed, or Paid

Stop and report immediately. Do not wait until you can prove the call was malicious, and do not hide a partial action because you feel embarrassed. Fast, accurate reporting gives the responsible team more options.

Tell IT, security, finance, or the designated incident contact exactly what occurred, including the time, device, account, channel, caller details, requested actions, and anything you completed.

- **You disclosed information:** List what you shared. Include names, customer data, internal details, recovery answers, and any information that could support another call.
- **You entered credentials:** Stop using the supplied page and contact security through a trusted route. Follow your organization’s account-protection instructions.
- **You approved MFA or added a factor or device:** Report which prompt, factor, account, and approximate time were involved. This may indicate an active session or persistent access.
- **You opened a link:** Do not revisit it to investigate. Report the link and what happened after it opened.
- **You started screen sharing:** End the session and report what was visible and whether the caller obtained control.
- **You installed software or pasted a command:** Stop following the caller’s instructions. Use the approved route to tell IT or security exactly what was installed or run. Do not remove tools or alter evidence unless instructed.
- **You sent files:** Identify the files, destination, method, and whether the files contained customer, employee, legal, financial, or security-sensitive data.
- **You initiated a payment:** Contact the authorized finance and banking process immediately. Provide the amount, destination, transaction status, and approval path.

Do not delete messages, clear logs, reset the device, uninstall software, revisit the site, or conduct your own investigation unless the response team directs you to do so. The right containment action depends on what happened and which systems are involved.

## Make It Safe for Employees to End the Call and Report It

Employees cannot consistently follow a verify-and-report rule if the organization treats verification as obstruction. Managers, IT, security, finance, and support teams need to make the safe response practical.

- **Publish trusted contact routes.** Employees should know where to find the official help desk, security reporting channel, finance escalation path, and emergency contacts without searching the open web during a crisis.
- **Set clear inbound-call boundaries.** Define which account changes, authentication actions, remote sessions, payments, and file transfers cannot begin from an unverified inbound call.
- **Document exception procedures.** Outages and urgent incidents need known fallback routes. Otherwise, an attacker can turn “the normal process is unavailable” into a universal bypass.
- **Protect the right to end the call.** State explicitly that employees may disconnect from anyone, including executives, customers, regulators, and security personnel, when verification is required.
- **Use no-blame reporting.** Measure how quickly and accurately employees report the interaction. Near misses and partial compliance contain useful defensive information even when the employee did not recognize the attack immediately.
- **Rehearse the words.** Practice IT, executive, bank, vendor, remote-support, and hybrid call-plus-email scenarios. Employees should say the exit phrase aloud, locate the trusted callback route, and complete the report.

Awareness is one layer. Organizations also need phishing-resistant authentication where appropriate, restrictions on unapproved remote-access software, [strong payment and impersonation controls](/blog/how-to-prevent-business-email-compromise), second approvals, telemetry, and an incident-response process.

## Rehearse the Live Call With Brightside

A written policy can tell employees to verify. A realistic rehearsal can show whether they remember how to do it while a caller sounds helpful, invokes authority, answers objections, and raises the stakes.

Brightside runs [live, adaptive AI vishing simulations](/vishing) rather than prerecorded voicemail tests. The simulated caller responds in real time to hesitation and resistance. Administrators can configure the attack goal, caller persona, employee context, tone, and tactics such as pretexting, authority impersonation, fear or threat, commitment escalation, social proof, and reciprocity.

That flexibility supports the behaviors covered in this guide. One scenario can test whether an employee challenges an unexpected help-desk call. Another can introduce a plausible ticket, then escalate toward MFA approval. An executive pretext can test whether seniority overrides the second-approval rule. A remote-support scenario can measure whether the employee ends the call before sharing a screen or installing software.

Brightside’s Voice attack type covers phone-only scenarios. Its Voice + BEC attack type coordinates a live call with a trackable phishing email, allowing the organization to rehearse the cross-channel path used when a caller sends a login page or other lure. Teams can use preset voices or create custom audio voice clones from a one- to two-minute recording, then take the call themselves in a test launch before launch.

The vishing dashboard reports failed rate, answer rate, median call duration, simulation totals, and failed-rate trends, with CSV export for further analysis. Those measures can help teams see where employees answer, remain engaged, perform the simulated target action, or need more practice. Teams should interpret the numbers alongside reporting behavior and the organization’s policy. Training metrics alone cannot prove that the organization will prevent a compromise.

Brightside is an awareness training and attack-simulation platform. Call blocking, caller authentication, real-time deepfake detection, communications monitoring, and incident response fall outside its scope. In this context, Brightside gives employees a controlled place to experience conversational pressure and practice the stop, verify, and report sequence before a real call.

## Vishing Red Flags FAQs

### What is the biggest red flag during a vishing call?

The most important signal is a request for a sensitive action that depends on you trusting an unverified inbound caller. Risk rises when that request is combined with authority, urgency, secrecy, a caller-controlled link or tool, or resistance to independent verification. You do not need proof of fraud. End the call and verify the request through an official route you find yourself.

### What should I say if a caller claiming to be IT asks me to stay on the line?

Say: “Our policy requires me to end the call and contact the help desk through the official directory. I’ll follow up there.” If the caller argues, repeat the boundary once and disconnect. Do not let the caller transfer you or supply the callback route.

### Can I trust a caller who knows my name, manager, ticket number, or company systems?

No single detail proves identity. Attackers can collect public information, buy stolen data, compromise accounts, question other employees, or study support procedures. Give the details to your official contact as context to check; they do not authorize you to share information or take action.

### How should I verify a suspicious call without using the number the caller gave me?

End the call first. Obtain the number or contact route from your internal directory, approved help-desk portal, authenticated customer portal, official website, payment card, trusted statement, or an existing business record. Explain the original request and ask the official function to confirm it. A transfer, link, QR code, or direct number supplied by the caller is not independent verification.

### What should I do if I already shared information or approved an MFA request?

Stop the interaction and report it immediately through your organization’s approved security channel. State exactly what you shared or approved, which account and device were involved, when it happened, and what the caller asked you to do next. Do not revisit a link, delete evidence, or try to investigate alone. Follow the response team’s containment instructions.
