Stop social engineering at your help desk
Catch attackers who target IT and support desk agents to reset credentials, unlock accounts, and bypass MFA, on the calls where access is one approved request away.
From signals to one action your team can take.
- Synthetic detectedCaller audioClone artifacts in the inbound voice, scored during the call
- DetectedPretextReferences a real open ticket to make the request look routine

Hold the reset. Agents receive a flag during the call before a reset is issued or access is unlocked.
A help desk attack is not one call
The attack is built to survive a single refusal. Here is each stage, and what Diopter does about it.
The pretext
AttackerLearns a real employee's name, manager, and org, then finds an open ticket to reference so the call sounds routine.
DiopterThe open ticket and prior correspondence read as context, so the agent's screen already shows the account's risk state when the call connects.
The inbound call
AttackerCalls the desk as that employee, often with a cloned voice.
DiopterInbound voice scored for cloning and synthesis while the agent is still talking.
The verification step
AttackerDeclines the callback to the number on record, citing travel, a dead token, or a manager waiting.
DiopterVerification resistance and authority framing scored against the steps your desk actually requires.
The escalating ask
AttackerA password reset becomes an MFA re-enrollment, then a new trusted device, then a privilege grant.
DiopterThe escalation arc is scored, and each ask is checked against what the desk may grant without a second approval.
The call back to a different agent
AttackerHangs up after a refusal and redials, reaching a newer agent with the same story and the same ticket.
DiopterThe same voice is matched across tickets and agents, so the second attempt arrives already flagged instead of starting from zero.
What Diopter looks for
Synthetic audio on inbound calls
Score the inbound caller for cloning and synthesis as the conversation happens.
Social engineering and pretext patterns
Detect the pressure, urgency, and authority framing that targets help desk agents under volume.
Out-of-policy verification resistance
Flag callers who push back on standard verification steps or invoke authority to skip them.
Cross-call consistency
Match the same voice across tickets and agents, so a caller refused by one agent is recognized when they immediately re-dial and reach another.
Where help desk attacks show up
- 01
Social engineering credential resets
Attackers call support desks impersonating employees, using scripted pressure to push agents into resetting passwords and bypassing MFA without proper verification.
- 02
Account takeover via IT support
A convincing caller with enough context about an employee can unlock accounts and change access before the agent realizes the request was fraudulent.
- 03
Device and MFA enrollment, the real prize
A password is temporary. Enrolling the attacker's own phone as a trusted factor is durable access that survives the reset, and it is the ask agents are least trained to refuse.
How a help desk attack unfolds
These attacks move through a recognizable sequence. Diopter scores that sequence while the call is still in progress.
An employee is impersonated
The caller presents as a legitimate staff member or contractor the help desk is expected to assist.
Something is locked and urgent
A locked account or a missed deadline frames the request as a simple fix the agent should handle immediately.
Verification steps are resisted
The caller pushes back on additional identity checks, citing urgency or invoking authority to shortcut the process.
Access escalates
A password reset becomes an MFA bypass, then a broader account unlock or privilege grant.
Credentials are handed over
The agent acts before confirming identity, giving the attacker a foothold inside your systems.
Most tools score one call. The attacker is working your queue.
A service desk is not one conversation, it is hundreds a day across a rotating bench of agents, and that is the weakness being attacked. The caller who gets refused does not give up: they hang up, redial, reach someone newer, and reference the same real ticket. Each call in isolation looks like a busy Tuesday. Diopter scores the inbound voice and the pressure pattern in the moment, and recognizes the same caller across tickets and agents, so being turned down once actually means something.
Help desk agents are trained to resolve quickly, and attackers exploit that training. The one who gets refused does not go away, they simply call back and get a different agent.
