Each time you connect to a public Wi-Fi hotspot, you increase your chances of being exploited by malicious actors. Whether it’s secure public Wi-Fi, the risks are the same. But with so many and so fast public Wi-Fi hotspots around, there’s no way of getting to the internet without trying one. In this situation, you ought to use the best cyber practices and various security and privacy mechanisms to ensure your internet traffic and data is safe.
İşte halka açık Wi-Fi erişim noktalarını kullanmanın bazı tehlikeleri hakkında bir özet;
Sadece basit araçlarla, kötü niyetli aktörler halka açık WIFI bağlantı noktalarından istedikleri bilgilere erişebilirler. Aşağıda bu araçların çalışma şekilleri yer almaktadır;
- Man-in-the-middle saldırıları (MITM) - Bu, kötü niyetli aktörlerin halka açık bir WIFI'a bağlandıklarında başlattıkları ilk saldırıdır. MITM'de kötü niyetli bir aktör, ağ trafiğinizi hedefine ulaşmadan önce engeller.
- Spoofing – This is a technique of masquerading or imitating a legitimate entity. For instance, after a MITM attack, a malicious actor can impersonate the receiver and send messages back to you. Malicious actors can even launch a complicated attack; website spoofing. Unsuspecting users will log into/access the website thinking it’s the legitimate one.
- Snooping - Koklama olarak da adlandırılan Snooping, kötü niyetli aktörlerin internet trafiğinizi paketler halinde yakalamak ve analiz etmek için kullandıkları bir tekniktir.
- Gizlice dinleme - Bu, temelde kullanıcının bilgisi olmadan belirli bir halka açık WIFI'da neler olup bittiğini dinlemektir, gözetleme yardımıyla kötü niyetli bir aktör mesajlarınıza ve konuşmalarınıza erişebilir.
Yukarıdaki teknikler sayesinde kötü niyetli kişiler halka açık bir Wi-Fi ağında istedikleri her şeye erişebilirler. Güvende olmak için, halka açık Wi-Fi ağlarında yapılması ve yapılmaması gerekenleri burada bulabilirsiniz;
Yapma. use public Wi-Fi to access any of your sensitive or confidential data. This usually involves your bank detail and any accounts that contain your personally identifiable information. Malicious actors are usually on alerts when you access certain information or websites. Your information can be used to blackmail you and propagate further attacks such as identity theft and fraud.
Yapma. use public Wi-Fi to do your online shopping. This is because purchases are involved which translate to your debit or credit card which further translates to your bank. Even if you have a separate shopping account with every cybersecurity detail taken care of, shopping online using public Wi-Fi isn’t the best practice as you risk everything, including your home address.
Don’t leave your devices unattended even if you’re in a secure public Wi-Fi hotspot. If you really have to, ensure its password-protected, and you have locked it. Malicious people can take a sneak peek of what you are doing or even take the opportunity to install malware on your device. Others might even steal your device, and you might end up losing all your data in case you don’t have any backup.
Do turn off automatic Wi-Fi scanning, connectivity, and adaptive Wi-Fi settings. Most devices offer this feature for your convenience but again they might be an open doorway for cybercriminals to access your data. Turn off your WIFI completely when not using Wi-Fi in public Wi-Fi hotspots. Hackers can secretly capture your devices automatic scanning requests and use them to wreak havoc.
Yapmak turn off Bluetooth connectivity. Besides, Wi-Fi, your Bluetooth connectivity can also pose a greater risk. Only use it in your home where you need to communicate with other smart devices. In public Wi-Fi hotspot, you definitely don’t need it. Similar to Wi-Fi, malicious actors can intercept your Bluetooth request and gain access to your device.
Herkese açık bir Wi-Fi erişim noktasındayken hem Wi-Fi, hem Bluetooth hem de konum hizmetleri kapatılmalıdır.

If you urgently need to use public Wi-Fi in any way, connect to a VPN first. A VPN will protect you against all public Wi-Fi vulnerabilities by encrypting your entire internet traffic using un-hackable encrypting standards. This encryption ensures that prying eyes and various malicious actors won’t get access to your internet traffic. Also, a VPN gives you anonymity as it assigns you a virtual private address that masks your actual IP address.
