Have you ever think twice before connecting to a free public access point in a café, airport or hotel? Did you ever wonder if public Wi-Fi hotspot, you need only one connection is legitimate, or if it could be a hotspot evil twin his costume?
An Evil Twin is a hotspot created by a hacker or cyber criminal access point Wi-Fi. It was designed to be a legitimate access point of an enterprise when imitating as a café with Wi-Fi to its customers.
A hotspot Evil Twin imitates a legitimate access point in almost every way, but his intentions are more sinister nature.
Hackers and / or cybercriminals Evil Twin hotspots, they both spy on the network traffic and insert data into the conversation between the victim and the servers that they, while connected to the Access Point Evil Twin can have access.
Cybercriminals phishing sites or pirate sites to mimic a legitimate access point and prompts users to join with him, so can steal account names and passwords, and redirect the victim to malicious sites, etc. Authors can also use the contents of the files that the victim or download, while connected to the Access Point Evil Twin.
Victims, the points are connected Evil Twin did not even know that they are not connected authorized to, because the authors the SSID (network name) of the access point of the legitimate access point. The experience is seamless to the victim. Most of the time the hacker that the victim in order to reach their intended targets, while Internet secretly spy on network traffic, allowing them to steal information from victims, the victims try to connect to your e-mail, provide numbers credit card when shopping online , etc.
How do I know if I connect to an evil twin to a legitimate access point?
You probably will not be able to tell if the connection to a good or bad access point. Hackers make every effort to use the same SSID as the legitimate access point. You go often and clone the MAC address of the access point to the truth that. Than a clone of the base station, which is reinforced the illusion
The Evil Twin hotspot owner can try the signal strength of the access point dominate self increase.
Hackers do not need to install a large access point based on the ugly material to create an access point Evil Twin. Hackers can use on your laptop as an access point emulation software access point that uses the network adapter supports Wi-Fi. With this level of portability and concealment that allows them closer to a potential victim, overwhelm the Help the signal from the legitimate access point can be placed.
What can I do to protect against Evil Twin Hotspots?
There are many ways to defend against this type of attack. One might think that the wireless encryption would prevent this kind of attack, but according to WatchGuard are not a deterrent because Wi-Fi Protected Access (WPA) is to encrypt user data to the connection between the device and network access point already victims founded.
One of the proposed by the Wi-Fi Alliance, protect against evil twin access points means is to use a virtual private network (VPN). I use the encrypted tunnel through the VPN encryption process ensures that all data provided for traffic between VPN and VPN device, Server.
Virtual Private Networks (VPN) are used to a luxury that only large companies could afford to offer their employees can, but now personal VPN services are plentiful and cheap, from about $ 5 per month. Visits to help our articles on personal VPN, select VPN service personnel.
In addition to avoiding open public access points, you can help reduce the risk of hearing Evil Twin hotspots that help pages to reduce their e-mail and other pages using HTTPS instead of HTTP connection unencrypted. Sites such as Facebook, Gmail and others have HTTPS connectivity.
