Risks and vulnerabilities in public WiFi networks
Free WiFi networks, although they represent immediate financial savings, carry significant risks for the privacy and security of users. According to Norberto Maldonado, founder of Kooltivo and managing partner of Sellcom Solutions, the absence of strict regulations on security standards allows companies and malicious actors to access personal data without explicit consent. This practice, common in commercial establishments, turns navigation information into a valuable asset for advertising purposes or, in extreme cases, a target for cybercriminals.
Lack of regulation and consequences
Maldonado highlights that, currently, any internet provider can operate a public network without complying with basic protection protocols. “There is no regulation that requires advanced encryption or secure authentication,” he warns. In Mexico, where the government manages more than 82,800 public access points, 90% of the population uses these connections, exposing themselves to leaks of banking data, access credentials or browsing histories.
A recent study reveals that open WiFi networks are up to 30% more vulnerable than fixed connections, due to techniques such as sniffing (traffic interception) or the creation of fake networks (honeypots). Hackers take advantage of this fragility to steal sensitive information, from emails to credit card details.
The economic value of data and solutions
Maldonado compares personal data to the “new oil”, highlighting its value in the digital economy. Platforms such as social networks or WiFi services monetize the information collected, while users are unaware of the extent of their exposure. During World WiFi Day, celebrated every June 20, awareness of secure practices is promoted, such as the use of virtual private networks (VPNs) or the verification of security certificates.
To minimize risks, experts recommend:
- Avoid financial transactions on public networks
- Disable automatic connection to available WiFi
- Use two-factor authentication on sensitive accounts
