Public Wi-Fi Risks

Public Wi-Fi networks — in cafes, airports, hotels, and coworking spaces — present genuine security risks:

Man-in-the-Middle (MITM) Attacks: An attacker positions themselves between you and the network, intercepting your traffic. They can see unencrypted data and potentially modify it.

Evil Twin Networks: Attackers create fake Wi-Fi networks that mimic legitimate ones. "Starbucks_Free_WiFi" might not be Starbucks at all.

Packet Sniffing: On unencrypted networks, other users can capture your network traffic using freely available tools.

Session Hijacking: Attackers can steal session cookies to access your accounts without needing your password.

The risk level depends on what you're doing. Browsing news on HTTPS is relatively safe. Accessing banking or entering passwords on public Wi-Fi is risky without additional protections.

Protection Strategies

1. Use a VPN: A VPN encrypts all traffic between your device and the VPN server, making it unreadable to anyone on the local network. This is the single most effective protection on public Wi-Fi.

2. Verify HTTPS: Ensure every website you visit uses HTTPS (padlock icon). Modern browsers warn about HTTP connections, but verify anyway. Never enter credentials on HTTP connections.

3. Forget Networks After Use: Don't let your device automatically reconnect to public networks. Disable auto-connect for public Wi-Fi.

4. Use Your Phone's Hotspot: When possible, use your phone's mobile data connection instead of public Wi-Fi. Mobile data is harder to intercept.

5. Enable Your Firewall: Operating system firewalls block inbound connection attempts from other devices on the network.

6. Avoid Sensitive Activities: Don't access banking, enter passwords for critical accounts, or transfer sensitive data on public Wi-Fi without a VPN.

Dead Man's Switch on Public Wi-Fi

If you frequently check in to your ZeroLatch dead man's switch from public Wi-Fi:

• Always use a VPN when checking in from public networks • Verify you're on the real ZeroLatch domain before entering credentials • Use the email-based heartbeat confirmation as an alternative (it doesn't require accessing the dashboard over Wi-Fi) • Enable MFA on your ZeroLatch account to protect against credential theft on public networks
