A group of security professionals challenges common cybersecurity advice that misleads the public. They argue that outdated tips, like avoiding public WiFi and frequently changing passwords, distract from more effective practices. Instead, they recommend focusing on software updates, multi-factor authentication, and using password managers.

A group of current and former Chief Information Security Officers (CISOs) has released an open letter aimed at debunking common myths about digital security risks that mislead the public, particularly everyday users and small businesses. They highlight outdated advice, such as avoiding public WiFi and never scanning QR codes, arguing that these fears are exaggerated. Modern encryption technologies and browser protections significantly mitigate risks associated with these practices. For example, the letter states that large-scale attacks via public WiFi are exceedingly rare and that modern devices prompt users before enabling data transfer when charging from public USB ports.
The authors recommend actionable security measures instead. They stress the importance of keeping critical applications updated, enabling multi-factor authentication (MFA) on sensitive accounts, and using strong, unique passphrases, ideally managed through a password manager. Organizations are encouraged to design systems that are resilient against user errors and to foster an environment where employees can report suspicious activity without fear of blame. Software manufacturers are called upon to prioritize security in their designs and to take responsibility for fixing vulnerabilities. The letter emphasizes that the onus of maintaining cybersecurity should not fall entirely on users; manufacturers must create safer products from the ground up.
