Public Wi-Fi poses many risks including data theft, malware distribution, and privacy breaches. Risks range from MITM attacks, session hijacking, to rogue networks and phishing. Protect yourself by avoiding sensitive transactions, using anti-malware tools, employing VPNs, verifying network legitimacy, logging out post-use, and scrutinizing permissions and URLs before access.

Risk of Personal Data Theft
When you connect to a public Wi-Fi network, there’s a chance that cybercriminals could access and steal your personal information. This includes passwords, financial data, and other sensitive details that you might enter while using the network. To combat this, avoid accessing sensitive accounts or performing banking transactions on public Wi-Fi.
Exposure to Malware
Public Wi-Fi networks are breeding grounds for malware distribution. Hackers can easily insert malware into your device without your knowledge, leading to potential data loss or damage. Ensure your device's anti-malware and antivirus software is up to date and active to provide a layer of protection.
Man-in-the-Middle Attacks
One of the most common risks associated with public Wi-Fi is the man-in-the-middle (MITM) attack, where an attacker intercepts communications between your device and the Wi-Fi connection. This can compromise any data transmitted during the session. To safeguard against this, use a virtual private network (VPN) which encrypts your data, making it difficult for attackers to intercept.
Unencrypted Networks
Many public Wi-Fi networks are not encrypted, meaning the data you send or receive is not secured and can be easily intercepted by cybercriminals. Always check for a secure connection (indicated by HTTPS in the URL) before submitting any sensitive information online.
Rogue Wi-Fi Networks
Hackers often set up fake Wi-Fi hotspots that appear legitimate but are actually designed to steal information from unsuspecting users. Always verify the network name with the establishment offering the Wi-Fi and look for any signs of suspicious activity.
Privacy Breaches
Using public Wi-Fi can expose your browsing habits and personal interests to third parties. This information can be used to build a profile on you for targeted advertising or more malicious purposes. Consider using privacy-focused browsers and extensions that block tracking.
Session Hijacking
Session hijacking is when a hacker takes over your online session by stealing the browser cookies on your device. This can give them access to your accounts as if they were you. To minimise this risk, log out from websites after you're done, especially on social media, email, and online banking sites.
Wi-Fi Sniffing
Wi-Fi sniffing involves the use of special software to eavesdrop on Wi-Fi signals. This allows hackers to monitor your online activities and capture any unencrypted data sent over the network. Avoid sending sensitive information when connected to public Wi-Fi, or use a VPN to encrypt your data.
Phishing Attacks
Cybercriminals use public Wi-Fi networks to carry out phishing attacks by directing users to fake websites that mimic legitimate ones. Once there, you might be tricked into entering personal information. Always double-check URLs and website authenticity before entering any details.
Overextended Permissions
Some public Wi-Fi networks require you to install an app or grant certain permissions to your device, such as location tracking or access to your personal data. Be wary of networks that request excessive permissions as this could be a ploy to gather your personal information for nefarious purposes. Always read through permissions carefully and only grant what is absolutely necessary.
