Jan 21, 2015. Experts predict a rise in criminals hacking 'free Wi-Fi' in 2015; To highlight the dangers, a virtual private network provider asked a seven-year-old to hack a. Public network hotspots (16 per cent); Supermarkets (15 per cent); Hospitals (8 per cent); Public offices (8 per cent); Schools and universities (6 per.
When it was known that a WEP network could be hacked by any kid with a laptop and a network connection (using easy peasy tutorials like those on our blog), the security guys did succeed in making a much more robust security measure WPA/WPA2. Now hacking WPA/WPA2 is a very tedious job in most cases. A dictionary attack may take days, and still might not succeed. Also, good dictionaries are huge. An exhaustive bruteforce including all the alphabets (uppercase lowercase) and numbers, may take years, depending on password length. Rainbow tables are known to speed things up, by completing a part of the guessing job beforehand, but the output rainbow table that needs to be downloaded from the net is disastrously large (can be 100s of GBs sometimes).
And finally the security folks were at peace. But it was not over yet, as the new WPA technology was not at all easy for the users to configure. With this in mind, a new security measure was introduced to compliment WPA. Wifi Protected Setup (WPS).
Now basically it was meant to make WPA even tougher to crack, and much easier to configure (push a button on router and device connects). However, it had a hole, which is now well known, and tools like reaver can exploit it in a single line statement. It still might take hours, but it is much better than the previous scenario in which months of brute-forcing would yield no result. Here's what wikipedia says about WPS- Created by the Wi-Fi Alliance and introduced in 2006, the goal of the protocol is to allow home users who know little of wireless security and may be intimidated by the available security options to set up Wi-Fi Protected Access, as well as making it easy to add new devices to an existing network without entering long passphrases. Prior to the standard, several competing solutions were developed by different vendors to address the same need.
A major security flaw was revealed in December 2011 that affects wireless routers with the WPS feature, which most recent models have enabled by default. The flaw allows a remote attacker to recover the WPS PIN in a few hours with a brute-force attack and, with the WPS PIN, the network's WPA/WPA2 pre-shared key.
Users have been urged to turn off the WPS feature, although this may not be possible on some router models. Working Of WPS.
Now while most of the things are the same as in WPA, there is a new concept of using pins for authentication. So basically, the client sends 8 digit pins to the access point, which verifies it and then allows the client to connect. Now a pin has 8 digits, and only contains numbers, so its a possible target for bruteforece.
Under normal bruteforcing of WPA passwords, you have to consider the fact that there may be number, alphabets, and sometimes symbols (and more than 8 letters). This make the task a billion billion times tougher. However, we can try thousands of keys per second, which make it a tad bit easier.
Now in WPS, there is a delay because we have to wait for APs response, and we may only try a few keys per second (practically the best I've seen on my PC is 1 key per 2 sec). Basically, 8 digits and 10 possibilities per digit (0-9) make it 10^8 (interpret ^ as raised to the power of)seconds if we assume one key per second.
Now that'll be years. So, where is this taking us? The answer is, there are flaws in this technology that can be used against it. Sam Sparro Sam Sparro Rar Extractor here. Now it might have been tough to carry out this attack at some point in history, but now, its a breeze. If you have all the prerequisites, then hacking the network would be as easy as reaver -i -b And if you are already familiar with hacking WEP, then just go to your Kali Linux terminal and type the above command (replacing what needs to be replaced).
Leave your machine as is, come back 10 mins later, check the progress (must be 1% or something), and go take a nap. However, if you're a newbie, then tag along. First off, you need to have Kali linux (or backtrack) up and running on your machine.
Any other Linux distro might work, but you'll need to install Reaver on your own. Now if you don't have Kali Linux installed, you might want to go to this page, which will get you started on. (Reaver has a known issue: Sometimes it doesn't work with Virtual Machines, and you might have to do a live boot using live CD or live USB of Kali Linux. See the last section of this post on = troubleshooting by scrolling down a bit). • Use airodump-ng. It will show all networks around you.
It tells which of them use WPA. You'll have to assume they have WPS, and then move to next steps. Airodump-ng mon0 None of them has WPS enabled, just saying. BSSID of the network - Now irrespective of what you used, you should have a BSSID column in the result that you get.
Copy the BSSID of the network you want to hack. That's all the information you need. So by now you must have something like XX:XX:XX:XX:XX:XX, which is the BSSID of your target network.
Keep this copied, as you'll need it. Reaver Now finally we are going to use Reaver to get the password of the WPA/WPA2 network. Reaver makes hacking very easy, and all you need to do is enter- reaver -i mon0 -b XX:XX:XX:XX:XX:XX Explanation = i - interface used. Remember creating a monitor interface mon0 using airmon-ng start wlan0.
This is what we are using. -b species the BSSID of the network that we found out earlier. This is all the information that Reaver needs to get started.
However, Reaver comes with many advanced options, and some are recommended by me. Most importantly, you should use the -vv option, which increases the verbosity of the tool.
Basically, it writes everything thats going on to the terminal. This helps you see whats happening, track the progress, and if needed, do some troubleshooting. So final command should be- reaver -i mon0 -b XX:XX:XX:XX:XX:XX -vv After some hours, you will see something like this.
The pin in this case was intentionally 12345670, so it was hacked in 3 seconds. • Sometimes, killing naughty processes helps. (see pictures below) • Move closer to target AP • Do a fakeauth using aireplay-ng (Check) and tell Reaver not to bother as we are already associated using -A (just add -A at the end of your normal reaver code) • If you are using Kali Linux in Vmware, try booting into Kali using USB. I don't know why, but sometimes internal adapters work wonders, and can't be used from inside of a VM. In my case, booting up from USB and using internal adapter increased the signal strength and speeded up the bruteforce process.
Update: It has nothing to do with internal adapter. I have verified this with many others, and it is now a known problem with Reaver. It does not work well inside Virtual machines. It is recommended that you do a live boot. • As far as rate limiting is concerned, there are few workarounds available in forums across the web, but nothing seems to work with 100% certainty.
Here is a, here is a which has a script and uses (it doesn't work for me, it's supposed to DOS the router and reset the ban temporarily), and here is a on the same issue, which has various possible solutions listed (including a [sorry if the download link on the thread there doesn't work] and hence allows reaver to work against routers which lock the particular MAC address which is attacking them and don't lock down completely). • Update: For some people the reason Reaver is not working is because the version of Libpcap you are using is not compatible with the version of Kali you are using.
Processes causing problems Kill 'em all. Anonymous hi, can i ask few question. First is i try cracking wpa2 pass, i almost finish cracking and at the last step need to use this command 'aircrack-ng -w wordlist.txt --bssid 00:11. Wordlist-01.cap' but it says that my wordlist can't be found. So how i want to check this wordlist or how can i make it. Second is i try to use this command 'wash -i [your interface] [My is wlan0] -c CHANNEL_NUM -C -s' but it only replay '[!] Found packet with bad FCS, skipping.'
' and never stop. Can help me please. Hope to get this info ASAP. Since I have only 150GB for Kali installation, I use Reaver all the time. Is one of the best tools I used. It doesn't consume disk space or hardware resources. Is just what everyone who's testing want.
One thing I do and could help someone, is to make Reaver start from a specified number. If you know the WPS default first numbers and you may think that WPS wasn't changed, you can Google to find the first 1, 2, 4 numbers. Then, you give all the information to Reaver you would put normaly, and, in the attribute -P put the first numbers you may know. Execute the command and stop it a few seconds later by pressing CTRL+C. Don't be scared if you saw that the WPS PIN sent is 4 numbers long.
Now, you should run again the same command but erasing -P this time. Now, program will think that it checked the previous PINs and will take less time. Or more, if the password is not default.
But if you have no patience, you could try it out. I.e., if you give to the app 4 first numbers, the scan will take only 1:30h with 999 tries. This is also a way to avoid the manual edit of './usr/local/etc/reaver/*.wpc'. Sorry for my poor English lvl, I did not sleep and I'm even worse.:c.
Hello, i am facing a lot of errors when i'm usin kali linux, actually i can't do anything because it comes with errors every time i try cracking wpa og creating Payloads. When using reaver i ger this error code: 0x04 i am typing in this reaver -i mon0 -b 'BSSID' -d 'delayed time' -S -N -vv where -S should increase cracking speed and -N should stop the nacking I have tried with -d 5/10/15/20/25/30 and also tried with and without -S i have tried with and without -N i have tried -c that specifies the channel. But it keeps saying WPS transaction failed error code: 0x04 Why is that? And when i try out this specific command reaver -i mon0 -A -b 00:30:4F:XX:XX:XX - c 6 -d 10 -vv --no-nacks --win7 It comes up with the error [!] WARNING: Receive timeout occurred Why is that, and how does i fix these reaver problems i am facing? I have researched on google for 2 days now, and no one has the answer i am looking for. Also when i use the wash command the RSSI = 0 on all the networks that i can find. I think this is the main problem for why reaver doesn't work And just another thing, when i try using the setoolkit, when i have pressed 1 - 10 and try pressing 1 for social engineering tool it says something about ratte_module not defined.
If someone has a link to fix that, i would be soooo happy:-). Anonymous Hey everyone I have a stupid question.
More password cracking action from! Today we aren't going to be cracking passwords per se, rather, we are going to learn the basics of generating and how to use them. First, let's go over how passwords are stored and recovered. Passwords are normally stored in.
When a password is created, the user types the password in what is called 'plain text', since it is in a plain, unhashed form. However, after a password is made, the computer stores a one-way hash of the password that obfuscates it. Hashes are made to be one-way, which means algorithmic reversal is impossible. This means we have to crack those hashes! Normally, when you crack a password hash, your computer computes a word, generates the hash, then compares to see if there is a match. If there is, the password is correct; if not, it will keep guessing.
Rainbow tables work on the principle of a time-memory trade-off. Digilent Usb Jtag Cable Driver Linux. This means that hashes are pre-generated by a computer and stored in a large rainbow table file with all of the hashes and words that correspond to them. This method works especially well for people with slow processors, since you don't have to compute much. Rainbow cracking can greatly reduce the amount of time it takes to crack a password hash, plus you can keep the tables, so you only have to generate them once!
Requirements • Windows, Mac OSX, or Linux OS • Admin, or root access Step 1 Download & Install RainbowCrack Text in bold means it is a terminal command (NT, OSX, or *nix). However, for this step, all commands in bold are for Linux only. The other operating systems use a GUI. RainbowCrack is the tool that we are going to be using to generate and use rainbow tables.
• RainbowCrack. • Extract the archive (Windows and Mac users extract via GUI). Tar zxvf • Change to the new directory that has been made from extracting RainbowCrack. Cd • Configure the installation../configure • Now, compile the source code for installation.
Make && sudo make install Step 2 Generate a Rainbow Table and Crack with It Now, lets generate a table that consists of all the alpha-lowercase and numeral characters. We want these to use the MD5 hash algorithm and be between 4-6 characters. All OS users must open a terminal, or a command prompt and be located in the RainbowCrack working directory. • In your working directory, issue the following command to start table generation. Rtgen md5 loweralpha-numeric 1 7 0 382 0 • Sort the tables so the processor can access them quicker. The table files will be in the current directory. Run the following command on each of the files in the directory ending in *.rt.
Rtsort This will take about 6 hours to generate on a single core processor. After you generate the table, let's practice using it on a word. • Let's hash the word 'burger' with the MD5 algorithm and then use our tables to crack it. Notice the b is in lowercase. Here is our result: 6e69685d22c94ffd42ccd7e70e246bd9 • Crack the hash with the following command, along with the path to your file.
Rcrack -h 6e69685d22c94ffd42ccd7e70e246bd9 It will return your hash. You'll see it is a lot faster than if you were try to bruteforce the six character hash. If you have any questions or want to talk, stop by our channel or start topics in the. Photo by Related.
