Public information
The pieces rarely look dangerous on their own.
A job title.
A supplier named in a tender.
A direct phone number in an old event programme.
A photograph from a conference.
A professional profile showing who reports to whom.
A company document that reveals how email addresses are structured.

How staff email addresses are built

Invented example: every person, company and document here is fictional.
Most of those details are ordinary. The problem changes when somebody connects them.
Together, public information can reveal who has authority, how an organisation works, who is likely to trust whom and what kind of request would feel normal.
That is where our work begins.
See the connection
The same public footprint can support several different kinds of risk.

Hi Bob, it's Alice. This is my other number, my phone's acting up.
I'm on the panel in Swakop all morning so I can't take calls.
Can you release the Dune Line payment before 12? They've moved banks, their letter is attached.

The Forum team
What is public
The organisation's website identifies the finance executive.
A conference programme and the forum's own post show that executive speaking outside Windhoek that morning.
A staff profile identifies the person who normally handles their requests.
A tender notice names the supplier the organisation is paying.
What it reveals
Someone can work out who has authority, who acts on their instructions and when normal verification may be more difficult.
What that can enable
A message from a new number claiming to be the executive suddenly has context.
The name is right.
The timing makes sense.
The request reaches the right person.
The information did not create the fraud on its own.
It made the approach more believable.
What is public
A tender notice identifies a supplier working on a project.
Public documents name people involved in procurement or finance.
Company material reveals enough about the project for an outsider to speak about it convincingly.
What it reveals
Someone can understand which supplier relationships already exist and which requests would look routine.
What that can enable
A request involving changed payment details or an urgent supplier issue may feel like ordinary administration instead of an attack.
The safest response is not permanent suspicion.
It is having a verification process that does not depend on information supplied in the request itself.
What is public
Staff names and roles appear on company pages, professional profiles and public documents.
The organisation publicly discusses the platforms, events or services its people regularly use.
What it reveals
Someone can identify the right audience and build a message around something those people already expect to see.
What that can enable
A phishing message can look less like random spam and more like normal work.
That is why awareness has to go beyond spelling mistakes and suspicious attachments.
One detail rarely creates the problem. The picture appears when the pieces are brought together.
Exposure Assessment for PW-EA-0319 · v1.1 · 28 Sep 2026
1.Summary
We reviewed publicly accessible information about the organisation and its finance leadership between 21 and 24 September 2026.
Four findings matter. Two are high priority because, taken together, they let an outsider write a convincing payment request in the CFO's name, send it to the person who acts on her instructions, and time it for a morning she is known to be away.

Security Awareness Training
Build judgement, not fear.
People still need to open emails, use WhatsApp, click links, approve payments and work online after the training ends.
Our sessions help people understand how social engineering works, recognise when something deserves a second look and know what to do next.
Where appropriate, we build the training around the organisation receiving it.

A cloned voice can sound exactly right. The new number, the urgency and the request for secrecy are the signal. Confirm on a number you already have.
