Avec de simples outils, les acteurs malveillants peuvent accéder à toutes les informations qu'ils souhaitent à partir des points d'accès WIFI publics. Voici comment ces outils fonctionnent ;
- Attaques de type "Man-in-the-middle" (MITM) - Il s'agit de la première attaque lancée par un acteur malveillant lorsqu'il se connecte à un réseau WIFI public. Dans le cadre d'une attaque MITM, un acteur malveillant intercepte votre trafic réseau avant qu'il n'atteigne sa destination.
- 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 - Le snooping, également appelé sniffing, est une technique utilisée par les acteurs malveillants pour capturer votre trafic internet en termes de paquets et l'analyser.
- Écoute - Il s'agit essentiellement d'écouter ce qui se passe sur un réseau WIFI public à l'insu de l'utilisateur. Grâce à l'espionnage, un acteur malveillant peut avoir accès à vos messages et à vos conversations.
Grâce à ces techniques, les acteurs malveillants peuvent accéder à tout ce qu'ils veulent sur un réseau Wi-Fi public. Pour plus de sécurité, voici quelques conseils sur les choses à faire et à ne pas faire sur les réseaux Wi-Fi publics ;
Ne pas 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.
Ne pas 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.
Faire 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.
Les services Wi-Fi, Bluetooth et de localisation doivent être désactivés lorsque vous vous trouvez dans un point d'accès Wi-Fi public.
