Best Tools To Hack Wifi (WEP/WPA) In Android, iPhone & PC.I am here to share knowledge of tools for How To Hack Wifi (WEP/WPA) In Android, iPhone & PC.

Welcome back, my rookie hackers! Split Screen Vista How Do I there. When Wi-Fi was first developed and popularized in the late '90s, security was not a major concern. Unlike wired connections, anyone could simply connect to a Wi-Fi access point (AP) and steal bandwidth, or worse—sniff the traffic. The first attempt at securing these access points was termed Wired Equivalent Privacy, or simply WEP. This encryption method has been around for quite awhile and a number of weaknesses have been discovered. It has been largely replaced by WPA and WPA2.

Despite these known weaknesses, there are still a significant number of these legacy APs in use. I was recently (July 2013) working at a major U.S. Department of Defense contractor in Northern Virginia, and in that building, probably a quarter of the wireless APs were still using WEP! Apparently, a number of home users and small businesses bought their APs years ago, have never upgraded, and don't realize or don't care about its lack of security.

The flaws in WEP make it susceptible to various statistical cracking techniques. WEP uses RC4 for encryption, and RC4 requires that the initialization vectors (IVs) be random. The implementation of RC4 in WEP repeats that IV about every 6,000 frames. If we can capture enough of the IVs, we can decipher the key!

Now, you might be asking yourself, 'Why would I want to when I have my own Wi-Fi router and access?' The answer is multi-fold. First, if you hack someone else's Wi-Fi router, you can navigate around the web anonymously, or more precisely, with someone else's IP address. Second, once you hack the Wi-Fi router, you can decrypt their traffic and use a sniffing tool like or to capture and spy on all of their traffic. Third, if you use torrents to download large files, you can use someone else's bandwidth, rather than your own.

This will start capturing packets from the SSID 'wonderhowto' on channel 11 and write them to file WEPcrack in the pcap format. This command alone will now allow us to capture packets in order to crack the WEP key, if we are VERY patient. But we're not patient, we want it now! We want to crack this key ASAP, and to do that, we will need to inject packets into the AP. We now need to wait for someone to connect to the AP so that we can get the MAC address from their network card.

When we have their MAC address, we can spoof their MAC and inject packets into their AP. As we can see at the bottom of the screenshot, someone has connected to the 'wonderhowto' AP. Now we can hasten our attack! Step 5: Inject ARP Traffic To spoof their MAC and inject packets, we can use the aireplay-ng command. We need the BSSID of the AP and the MAC address of the client who connected to the AP. We will be capturing an ARP packet and then replaying that ARP thousands of times in order to generate the IVs that we need to crack WEP. • aireplay-ng -3 -b 00::09:58:6F:64:1E -h 44:60:57:c8:58:A0 mon0.

If we have enough IVs, aircrack-ng will display the key on our screen, usually in hexadecimal format. Simply take that hex key and apply it when logging into the remote AP and you have free wireless!

They're absolutely great for a nooby like me.:) BTW: I've just craked a neighbour's WiFi, but I can't get an IP from her router's DHCP nor I can connect with an static IP. In your opinion, what do you think is the cause for that? Recycler Virus Removal Antivirus more. Also, I was following the tutorial, and meanwhile on my PC I've changed directories on the cli. It turns out that airodump-ng writes the.cap file on the cwd, and it took me 25 minuts of reading man pages, until it occured to me where the files where, since misteriously they weren't appearing on the Home directory.:) Reply. Thanks, I'll try it.

Nop, I'm using BackTrack. Reading the answer you gave to Hersey I got a little confused and I thought that airodump-ng made /root (or any other user's /home) the default location for creating the.cap files, but it turns out that it leaves the files wherever you happen to be on the terminal when you launch the command. Now that I think of it it's obvious that as a command line general rule, you execute the command on the directory you happen to be and the results are written on the same place unless specified otherwise.
