Wifite is probably one of the best tools out there for cracking wireless networks. It just makes the whole task so simple for you by hiding all the intricate details of cracking a wireless network and making the whole process automated. It can crack WEP/WPA/WPS encrypted networks in a row. Some of the features of Wifite are..
As you can see from the figure below, it found 2 nearby networks. It also lets you know if it found any clients connected to it, as it is important sometimes to have a client associated with the network too. Press Ctrl + C when you think wifite has found all the nearby wireless networks.

Wifite also offers some other cool customization options. For e.g the following command will ask wifite to endlessly attack the target WEP network. This means that the program will not stop until it has cracked the WEP key for the target network. This attack could be handy in case you are near a network that does not have any connected client to it or has very little activity. Just use this command and forget about it, wifite will automatically crack the WEP key as soon as it gathers sufficient information.
You will also notice that it informs you whether you have already cracked the network by looking at its database. Having a database is another handy feature as it stores all the cracked passwords for all the networks as well as any captured WPA handshakes so that you can carry out a bruteforce attack whenever you want.
The following command will scan for all nearby WPA networks and store the WPA handshakes without carrying out a bruteforce attack. This feature could come in handy when you want to gather the information as quickly as possible in a particular location. You can always crack the WPA key using the handshake somewhere else.
Iphone Analyzer is an IOS device forensics tool. Unlike its name, Iphone Analyzer works for all IOS devices. It is used to analyze data from iTunes backups and provides a rich interface to explore the contents of the device as well as recover them. In the case of Mac OS X, Iphone Analyzer automatically detects the location of the backup file. However, while using it with Backtrack 5 R3, you will have to provide it with the location of the backup file. It also allows you to analyze your IOS device over SSH, which is a very handy feature. Though this feature of Iphone Analyzer is still in the beta version, this feature can be very useful, especially when performing penetration tests on jailbroken IOS devices. Iphone Analyzer allows you to see your text messages, photos, call records etc. IOS uses sqlite for managing its database. Iphone Analyzer also allows you to analyze the various sqlite files, the schema which is used to enter data into the database as well as the contents of the file. It also allows you to browse the file structure like you would normally do via a terminal on a jailbroken device.
Once this is done, you are presented with this beautiful interface that allows you to explore the contents of your backup file. At the top-center, you will see a lot of information about the IOS device like GUID, Serial Number, UDID, the last backup date, the phone number etc. On the bottom of this, you will see a detail section which contains all the information that Iphone Analyzer could obtain from the info.plist file. On the left side, you will see a Bookmarks and File System section. On the right side is the Manifest section. This gives you a lot of the information about the actual path of your applications in the directory structure. Please note that since this is not a jailbroken device, most of the information will be non-readable.
This tutorial will demonstrate how to use the pre-configured Automated Penetration Test feature. When this feature is invoked, the OG150 will run through 11 pre-configured tests to provide a wealth of information about the target infrastructure. This information includes, but is not limited to, the following; services running on host machines (NMAP scan), FHRP (First Hop Redundancy Protocols) in use, routing protocols in use, wireless networks (and the associated security settings) within range of the OG150, and much more. This information could be used for more focussed attacks. The tutorial explains how to invoke the penetration test manually and automatically upon bootup. In addition, a bonus section explains how you can configure the OG150 to automatically email you the 'Security Report' (penetration test results).
This 10-page tutorial starts with a theoretical analysis of WPA/WPA2 PSK security. You will understand the process that is used by WPA/WPA2 PSKs, according to the IEEE 802.11i standard, to secure wireless traffic and how this process can be manipulated to crack the WPA/WPA2 PSK. A practical demonstration of the cracking process using the OG150 follows. The practical demonstration cracks a WPA2 (AES) PSK configured on a Cisco access-point using the OG150s built-in software packages. If your OG150 has been deployed with 'Reverse SSH Tunnel' functionality, you can literally crack wireless WPA/WPA2 PSKs from ANY location in the world. Finally, I discuss the myths, limitations and security prevention measures when using WPA/WPA2 PSKs.
This tutorial will demonstrate how you can use your OG150 to crack WEP (Wired Equivalent Privacy) keys. It is fairly common knowledge that WEP provides almost zero wireless security, given the flaws that have been exposed and demonstrated many times. This tutorial will re-affirm that WEP is not secure and demonstrates how quickly a wireless deployment that uses WEP keys can be exposed.
It comes with the Offensive Security Wireless Attacks video and PDF course, which aims to prepare students for the exam. In this article, I take the time to talk about my experience with this certification, the pros and cons of the course, thoughts after taking and passing the exam, etc.
Despite what some people have to say about this course, I personally thought it was well made and provided me with some new knowledge. Considering it is an Offensive Security course and it is relatively brief and inexpensive, which makes it a fairly small investment in terms of both money and time, it is definitely worth it.
I am a penetration tester and cyber security / Linux enthusiast.Through this blog, I would like to share my passion for penetration testing, hoping that this might be of help for other students and professionals out there. I will be more than glad to exchange ideas with other fellow pentesters and enthusiasts.
Originally I was using Fern in Kali and ran into some issues with my wireless adapter and with the program freezing or not opening after updating it. I have the fixes I discovered in another blog post for anyone else that may have these same problems.
Common.txt is the wordlist that comes with the Fern program, but any wordlist you download or have created on your own can be used by hitting the Browse button and pointing Fern to the alternative wordlist file.
Hi Sir! Could you tell me please, how much time does Fern WIFI Cracker takes if I bruteforce WPA encryption with WPS flaw in condition of processing power 2.2 Ghz dual cored AMD Turion microprocessor? While I was cracking WPA with dictionary attack on Airocrack-ng it shows 500 words per second. Can I guess same indications on Fern Cracker or is it cracks less combinations because my microprocessor is generating them? Do you have some articles about WPS cracks and How it works on Fern WIFI Cracker?
Fern is a GUI interface and uses the Reaver utility to crack the WPS flaw. I used the Reaver utility and usually run into issues as most APs notice the repeated tries of pins and stop answering the requests. There are settings to control asking a new pin less frequently to trick the AP, but many successful attacks with Reaver take hours, and I look at other attacks before Reaver since I get impatient with Reaver!
Fern and some of the other WiFi tools can be a challenge at times to get to work! I went through a lot of issues with Fern, and the power of Google is your friend to research any issue! It could be anything from your WiFi adapter is not able to do all the functions, or the install may be corrupt, or a config setting may be set wrong. Please post any error messages or more details of your issue and I can try to help diagnose what the issue is.
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!
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 Wireshark or tcpdump 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.
As you can see from the screenshot above, there are several APs with WEP encryption. Let's target the second one from the top with the ESSID of "wonderhowto." Let's copy the BSSID from this AP and begin a capture on that AP.
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.
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. 2ff7e9595c
