The risk

Where vendor impersonation shows up

Banking detail changes under pressure

Spoofed vendors pushing accounts payable to update payment details for an urgent invoice or onboarding.

Established-relationship abuse

Attackers who reference real invoices and history to make a redirect feel routine.

The attack playbook

How a vendor impersonation attack unfolds

These attacks move through a recognizable sequence. Diopter scores that sequence while the call is still in progress.

01
Authority

A known vendor reaches out

The caller references real invoices and history, presenting as a supplier the team already pays.

02
Urgency

An urgent invoice

A late payment or a deadline frames the banking change as time-sensitive.

03
Isolation

A new point of contact

The request comes from a fresh email domain or number, away from the established channel.

04
Escalation

The change is pushed

A detail update becomes a full banking redirect for current and future payments.

05
The ask

Payment is redirected

Accounts payable updates the record and the next payment leaves for the attacker's account.

How Diopter helps

What Diopter looks for

01

Identity and payment verification

Confirm the vendor contact and validate the new banking details against fraud signals.

02

Synthetic media on vendor calls

Score the call for cloned voice and deepfake video used to authorize the change.

03

Pressure and policy checks

Detect the urgency and out-of-policy framing that accompanies a payment redirect.

Verdict
Hold the banking-detail change

Diopter holds the banking-detail change for verification before accounts payable updates the record.

Why Diopter

Most tools check one clip. Diopter reads the whole call.

Point-in-time detectors answer a single question: is this video or voice fake? A good clone passes that test. Diopter scores the whole conversation, the authority claims, the manufactured urgency, the push to go off-channel, and the escalating ask, then raises a verdict on the pattern a single frame cannot show.

A spoofed vendor can sound routine. A real banking-detail change does not arrive under pressure, off-channel, and outside your controls.

Deployment & trust

Light to deploy, clear about what runs where.

Pilot in days, roll wider through MDM, and keep sensitive call media inside your perimeter.
