Stop help desk vishing before credentials change.
Scattered Spider-style attacks can turn help desk resets into account takeovers. imper.ai detects impersonation and scores the risk. For established employees, AI-Driven Contextual Verification adds work-based assurance when needed.
How imper.ai works
From help desk request to secure recovery.
Agent-assisted, IVR, and self-service requests use the same verification flow. imper.ai assesses impersonation risk and returns a result before credentials change.
Initiate verification
The requester enters a secure, browser-based verification flow through the existing recovery process.
Sends a secure link during the call.
Initiates verification through the phone system.
Starts verification within the recovery portal.
No app installation. When work email is unavailable, an approved alternative such as SMS can deliver the link.
Detect impersonation and assess risk
When the link opens, imper.ai analyzes the operating environment and produces an impersonation risk score. Additional assurance can be applied where needed.
Complete or escalate recovery
The results return to the recovery workflow before a password reset, MFA change, or account unlock.
Approved requests continue, including automated recovery.
Require manager approval where policy calls for it.
Hold suspicious requests and alert the right team.
Two technologies behind the decision
Impersonation Detection Engine
Analyzes device, network, location, environment and behavioral signals to identify impersonation patterns and produce a real-time risk score, even on the first interaction.
AI-Driven Contextual Verification
When additional assurance is needed, uses dynamic questions based on an established employee’s recent work activity in connected systems such as email, calendar and HR.
Illustrative question: “Which meeting did you attend yesterday?”
Built into recovery
Secure resets in the tools your help desk already uses.
Bring the decision into ServiceNow, without moving agents into a separate console.
The help desk task receives the result. Approved recovery can continue through connected identity systems; other requests remain with the appropriate team.
Return the score and any verification outcome directly to the agent.
Let approved resets continue through connected identity systems.
Route requests for additional approval, proofing or security review.

Why now
Why attackers target the IT help desk.
Scattered Spider and other social-engineering attackers exploit routine password and MFA recovery. Stolen employee information makes their calls more convincing.
Voice phishing drives cloud intrusions
Mandiant ranked voice phishing the top initial infection vector in its 2025 cloud investigations.

Also tracked in reporting as UNC3944 or Octo Tempest, Scattered Spider has used employee impersonation to target help desk resets. MGM is a prominent example.

A compromised account can become a business-wide incident.
A fraudulent reset can lead to operational disruption, data exposure, and costly recovery. The impact is not limited to global enterprises.

For a smaller company, the fallout can mean missed orders, interrupted services, and days of incident response.
Gartner Hype Cycle for Digital Identity, 2026
A new workforce identity control has entered Gartner’s Digital Identity Hype Cycle.
Workforce Identity Impersonation Detection
Gartner tracks Workforce Identity Impersonation Detection as an emerging technology focused on attacks that arise when threat actors impersonate employees, especially in social-engineering scenarios.
Production evidence
Impersonation leaves detectable traces.
Across 450 password-reset attempts reviewed at a retail help desk, imper.ai found suspicious patterns in individual requests and across repeated interactions.
On a single request, imper.ai identified VPN, latency, and channel inconsistencies. The agent had noticed nothing unusual in the caller’s voice.
The same employee identity appeared across sessions with different devices, locations, ISPs, and phone infrastructure.
The same environment and phone number appeared behind two employee identities within hours.

What is help desk vishing?
Help desk vishing is voice-based social engineering. Attackers impersonate employees to persuade IT support to reset passwords, re-enroll MFA, unlock accounts, or change recovery details.
How can companies stop Scattered Spider-style help desk attacks?
Evaluate the requester before resetting credentials. imper.ai detects impersonation, produces a risk score, and can verify established employees through recent work context when additional assurance is needed.
Can employees be verified when their work email is locked?
Yes. An agent can send the secure verification link through an approved alternative, such as SMS, when the employee cannot access work email.
Does every employee have to answer work-context questions?
No. Contextual verification can be used for established employees when additional assurance is appropriate. It is not required for every recovery request.
How does imper.ai work with ServiceNow and other recovery channels?
imper.ai returns risk and verification results to supported recovery workflows, including ServiceNow, IVR, and self-service. Organizations can configure when to proceed, step up, review, or stop.
Stop impersonation before the reset.
Detect risky recovery requests and verify established employees through their work context before passwords or MFA factors change.
