Hence he may either be logged in as you in your e-mail account (I can confirm Yahoo Mail is vulnerable to this) or simply use that one password you used for, say, Neopets, to login to your PayPal and drain your bank account.Wireshark is a network packet analyzer. A script on his machine can check the packets coming through until you do something over HTTP, the unencrypted transfer protocol which will enable sniffing of your cookies and passwords. Once the attacker has created this foundation it is a matter of waiting and watching. This makes him much more likely to see your data. This involves the attacker announcing that he is your router and any data you have bound for the gateway then goes via the attacker. To make such an attack more efficient, the attacker would usually issue an APR (ARP Poison Routing) attack on the network.
This allows programs like Wireshark to see all packets broadcast on the network - he must of course have your wifi decryption keys but WEP is practically insecure to someone with very basic tools. It basically involves a client associated with your access point in promiscuous mode. Sniffing wireless traffic is shockingly simple if you use anything less than WPA2 to secure your network. Anyone on the wire could then sniff your traffic as if it had been sent across an open (unprotected) network on the air. On the wire, traffic is not protected by the same encryption (WEP/WPA/WPA2) that applies to the wireless connection. The only real additional threat that a malicious network administrator would pose, is that they have access to the wired side of the network also. Even then, many of these higher-level protocols can be subjected to man-in-the-middle (MitM) attacks if the victim is less than vigilant in verifying their SSL certificates (or the attacker has a certificate from a compromised CA). At this point, the only defense you have is encryption at higher levels of the network stack (i.e.: HTTPS).

Once they've cracked your key through this method, they can join the network like any other user (provided you don't have other protections - most of which are trivially bypassable - in place).įor WPA and WPA2, there are known weaknesses that allow authenticated users (or attackers who have broken into the network) to sniff traffic as if it were unprotected. Currently, the Wi-Fi Protected Setup (or similar) features in most SOHO routers has a weakness that will allow an attacker to gain access to your network in fairly short time. There are side-channel attacks to WPA and WPA2 though. With WPA and WPA2, that just means a lot of time. As with just about any cryptography, brute force will always win if given enough time.

For these, an attacker would most likely monitor traffic for awhile and then take the data home for offline cracking. WPA and WPA2 require a good bit more computational power for outsiders to crack, and much more time. WEP security adds a slight barrier, but is still easily decipherable by even unauthenticated users. This includes usernames and passwords as well as web pages, documents, and other data sent or obtained via http, ftp, telnet, etc.įor open networks, gathering cleartext data is as easy as sniffing the traffic in the air. On any Wi-Fi network - encrypted or not, given today's Wi-Fi encryption protocols - any sufficiently skilled and equipped user of the network (and especially the network administrator) could easily access any data you transmit or receive via cleartext protocols. That said, the answer I've given there applies fairly well here. Is it possible to get all the data I send through wifi? There's a question very similar to this already, but not quite an exact duplicate.
