Purple, a global provider of guest WiFi solutions, is urging businesses to strengthen their digital security following a live demonstration that exposed how insecure WiFi networks can be exploited to steal sensitive data. At an event held on March in Newcastle, cybersecurity specialist Eliza May Austin demonstrated how attackers can take advantage of weak network configurations using a technique known as an “evil portal.” With a compact device small enough to fit in a handbag, she was able to replicate a legitimate WiFi network within seconds and intercept user traffic without detection.
The session revealed that cyber threats do not always require advanced techniques. In many cases, attackers can simply exploit poorly secured networks in everyday environments such as cafés, hotels, and offices. Once connected, unsuspecting users risk exposing login credentials, personal data, and other sensitive information. A major concern highlighted during the discussion was the continued use of shared passwords and the practice of running guest WiFi on the same network as critical business systems, including Point of Sale (POS) infrastructure. This setup significantly increases the risk of unauthorized access and data breaches.
The panel, which included Purple CEO Gavin Wheeldon and legal expert Alex Craig from Muckle LLP, emphasized that such vulnerabilities not only threaten data security but also create compliance challenges. Businesses may struggle to meet regulatory requirements under frameworks like GDPR and the Investigatory Powers Act if proper safeguards are not in place.
Gavin Wheeldon noted that smaller businesses are often prime targets because attackers perceive them as easier to breach. He stressed the importance of moving toward identity-based, passwordless security models that reduce reliance on human behavior often considered the weakest link in cybersecurity. Key takeaways from the event included how easily attackers can clone WiFi networks (SSIDs) to harvest user data, the dangers of combining guest and internal networks, and the legal responsibility businesses hold in protecting customer information.
Purple also showcased its passwordless approach, which replaces shared credentials with automated certificates to establish secure, encrypted connections that are far more resistant to interception. To support organizations in addressing these risks, Purple has made the full demonstration available, offering practical insights into how vulnerabilities can be exploited and how businesses can transition to more secure, automated network environments.
