Deepfakes Already Hitting Businesses as Often as Traditional Fraud, Regula Survey Finds17.9.2025 08:00:00 CEST | Press release

Fresh survey data from Regula, a global developer of identity verification (IDV) solutions and forensic devices, shows that the line between traditional fraud and impersonation attacks has vanished. Identity spoofing, biometric fraud, and AI-powered deepfakes have already struck one in three organizations worldwide, catching up with long-standing fraud tactics like forged documents and social engineering. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20250916314726/en/ Regula’s survey shows that impersonation attacks overtake traditional fraud schemes. Three impersonation-driven tactics now dominate the fraud playbook, each exploiting weaknesses in verification: Identity spoofing (reported by 34% of organizations) — Holding up a printed photo, replaying a video, or showing a screen image to a camera. Often used to mass-open accounts for scams or mule networks. Biometric fraud (34%) — Physical deceptions like fake fingerprints

Overture Life Launches European Preorder Waitlist for DaVitri, the World’s First Microfluidics-Based Automated Vitrification Platform17.9.2025 07:00:00 CEST | Press release

Ahead of receipt of anticipated CE Mark, European customers can begin requesting DaVitri to expand patient access to high-quality IVF Overture Life, the innovator modernizing IVF to optimize reproductive freedom, today announced the launch of its European preorder waitlist for DaVitri, the world’s first automated vitrification platform. The waitlist ensures in vitro fertilization (IVF) facilities will be among the first in Europe to harness DaVitri to reduce manual workloads for their embryologists while eliminating operator variability, thereby providing patients with faster, more consistent procedures. As infertility rates spike worldwide, interest in egg freezing continues to rise while the infrastructure to support it lags behind. Egg freezing requires vitrification, typically a time-intensive, manual process vulnerable to human error that can only be performed by extensively trained embryologists. This has resulted in variability in egg and embryo survival rates that directly impa
