Fraud Alert: Ignore Emails Requesting Accommodation Details
We have been informed that some of our conference participants have received fraudulent emails falsely claiming to manage accommodation arrangements for the upcoming IRMMW-THz 2025 in Espoo this August.
These emails may have subject lines such as:
“Gentle Reminder: Confirm Your Accommodation Reservation for Upcoming Conference”
and are signed by a so-called “Reservation Team”.
Please be advised that these messages are not sent by us — the official organisers of the conference — and we are not coordinating hotel bookings via email or through any third-party service.
We strongly advise you to:
Ignore and delete such emails.
Do not respond or share any personal or travel information.
Do not click on any links or open attachments in suspicious messages.
All official communication regarding the conference will come only from our verified email addresses (irmmw-thz2025@taloevents.fi or secretariat@irmmw-thz2025.org) and via the official conference website.
If you are ever unsure about the authenticity of a message, please don’t hesitate to contact us directly.
