Torrent Cracking 4 Way Handshake
Short answer is, 4-way handshake password 'cracking' works by checking MIC in the 4th frame. That is, it only checks that KCK part of the PTK is correct. 4-way handshake doesn't contain data that would allow checking of other parts of the PTK, but that's actually not needed, for two reasons. As the topic suggests really, how many parts and which parts of the 4 way handshake is needed by hashcat to crack WPA/2 and what does hashcat use to crack WPA/2. I only have parts 1, 2 & 3 of the 4 way handshake is that enough for hashcat as i'm finding it difficult to get a full 4 way handshake? Wireshark WPA 4-way handshake. Ask Question Asked 7 years, 5 months ago. Active 5 years, 6 months ago. WPA/WPA2 Requirements The capture file must contain a valid four-way handshake. For this purpose having (packets 2 and 3) or (packets 3 and 4) will work correctly. In fact, you don't truly need all four handshake packets.
Trying to capture a 4-way TKIP handshake without help can involve sitting and watching traffic for hours and hours, waiting for a client to connect to a network. By using a tool called aircrack-ng we can forcefully deauthenticate a client who is connected to the network and force them to reconnect back up. During the process of re-exchanging the encrypted WPA key, you will capture a handshake. In order to forcefully capture a 4-way handshake, you will need to deauthenticate a client computer that is actively using services, forcing it to exchange the WPA key and in turn capturing the handshake that can be decrypted. Things you will need in order to complete this exercise:. A copy of Linux with the program aircrack-ng installed and wireless drivers patched for injection (I recommend Backtrack-linux since it has all these things already).
A compatible wireless card. You can check the for compatible cards.
A wireless access point with WPA/WPA2 PSK encryption. Another device or computer connected to the access point Step 1: Put the interface in monitor mode. Assuming you are booted up and ready to go, you’ll need to put the interface in monitor mode and get ready to start dumping packets from your target network. Airodump-ng -c 6 -bssid 00:1D:7E: 64:9A:7C -showack -w capture mon0 Required Airodump Switches:.c specifies the channel to listen on. –bssid specifies the target MAC address.
–showack tells airodump to give verbose ACK related information.w specifies the file to save the handshake to Example airodump-ng output: If you do not yet know the bssid of the target you can omit that part of the command to see a list of all access points on the specified channel. You should at this point take note of the mac address or bssid of the target access point and the mac address of the connected client you are going to deauthenticate. Step 3: Deauthenticate the client who is already connected and force them to exchange the WPA key as they connect. Open a new terminal and deauthenticate the victim from the target network. Aireplay-ng - 0 5 -a 00:1D:7E: 64:9A:7C -c 00: 25:D3:0B: 71: 15 mon0 Required Aireplay Switches:.0 6 tells aireplay to inject deauthentication packets. The 6 is the number of packets we wish to send.a is the wireless access point MAC address.c is the client MAC address. Example of a deathentication session: A successful attack will show ACKs, which indicates that the victim who is connected to the access point has acknowledged the disconnect we just issued.
It is possible to send just 1 deauthentication request, but depending on the range of you to the target wireless network sometimes more than 1 request is needed. Step 4: Ensure you have captured the 4-way handshake. Going back to the airodump-ng terminal which should still be running and collecting packets we can look in the upper right hand corner to see the programs acknowledgment that we have indeed captured a WPA handshake. This can also be done by running aircrack-ng on the capture file. Aircrack-ng capture-02. Cap Example aircrack-ng output Step 5: Upload the handshake to ph33rbot.com Since running a dictionary attack against a WPA handshake can be a long drawn out cpu intensive process, Question-Defense has a online WPA password cracker which can be used to test your capture.
The process is simple. Access the and fill in the required information. You will be charged a small fee of ten dollars to test your capture against a wordlist made up of around 540 million words and the results will be returned to you in a few hours via email.
Example of correct upload. Aireplay-ng -0 5 -a 00:1D:7E:64:9A:7C -c 00:25:D3:0B:71:15 m I get that the 10series after -a is the bssid, but what is the second series after -c refer to?
Is that a MAC address? Mine or the client?
With my router being the only WPA in my zone, the 10 WEPs will provide more than ample coverage, but I just would like to perfect this technique for free, so I will have to decline the offer of $10, but thank you for providing such a service. We can only give you our word as IT professionals that it is not a scam.
I can asure we have well paying jobs and are not interested in scamming a few $10.00 here and there. If you really wanted to test it out then create a capture with a easy password and submit it. Once the password is recovered, then you will know the service is legit.
Then you can submit your real capture. If you want to use the service its there for you to use, many people from all over the world use it frequently.
I would also imagine that after over a year of being online, if it was a scam people would be warming each other.So to sum it up there is really no basis for saying we are scammers. I think you provide a needed service and your price is very fair given the cost of the GPU’s to do fast brute force attacks. However, I have to agree with the prior commenter that it is doubly disappointing to not only pay the fee, but get no results.
Why not simply charge nothing when you cannot find the key, but a little more when you successfully find the key to make the same return on your investment? I know of another service, which I will not post here, that has their price structure that way and it seems more fair because if there is “no recovery” then that may be attributable to the size or quality of your dictionary, etc. I just think you would have a lot less hard feelings in those cases where you don’t find passwords. And you would not have people suspect you of anything like the first poster here. People will only say good things about you and refer business. Personally, I’d much rather pay $20 for a guaranteed result than $10 for no result. Keep up the good work.
The price of the hosting and the electricity does not change for us. Running the crack cost us the same amount of time, money and resources whether we find the password or not.
So thats why we charge 10 dollars. If you have found a better service then by all means use it but as far as I know there is no service that even comes close to the amount of words and success rate that we have.
In the two years we have been in business, we have seen many of these types of services come and go, they never last long because what happens is they realize that it costs money to run a service like this. I would love to do it for free but the fact of the matter is we are not going to spend hundreds of dollars a month to provide a free service so that we can be “nice guys”. If you do not like our prices and results we highly encourage you to test out some of the other services and see how you far you get. This is directed to purehate from whom I gained much guidance, wisdom and clarity. In cracking WPA we are working are an intigrated approach which employs both social engineering and remote viewing to obtain a basic understanding of any key.
WPA is an excellant target cypher as the structure of the key is well defined. At this time we suggest the following approach which has shown real results. Those approaching the WPA problem should first crack as many WEP keys in the area to get an idea of how users select keys. We have found that in over 50% of the cases the key is derived from only one(1) source.
This source is totally numeric and easily broken by a crunch-aircrack passthru in BT4R2. A hint of that source can be found below: /pentest/passwords/crunch/crunch 10 10 “” -t 08@@@@@@@@ aircrack-ng /root/hanshake.cap -e “bssid” -w – When we applied this attack to 100% of the handshakes captured we cracked 50% in less then three hours using GTX360 video cards.
We are designing Remote Viewing sessions to directly attack cyphers. As the WPA structure is well known we are currently designing random pages to be employed in remote viewing sessions to obtain the basics of the bssid’s WPA cypher key. From remote viewing you will obtain 1. The key length, 2.
Key types ie numeric, numeric-caps etc(12 variables) and 3. The first three(3) characters of the key. You can then decide whether a pass-thru in cruch or pyrite etc is practicable with the equipment you have available.
For those interest turn to Ed Dames, learn rvcom. You will find methods to obtain three numbers in a lottery.
We think the average person can employ stage three remote viewing to obtain the basics of a keys structure and then fine tune crunch to obtain the key. I will be posting expansions to this theme in fiurther posts. SRC – Up All Night. Hi, ive been looking into Cracking WPA for some time now, i have had great success in cracking WEP.
Ive never found a WEP that Aircrack-ng couldnt crack in 30-45 seconds with enough packets as little as 50000 will do the job. But WPA is a whole different ball game. Its about capturing the 4 way handshake and then poking it till you find the right word. Often its entirely impossible due to not having a good enough dictionary or just a plain old lack of patience in most cases.
If its not any of those then the key is good and cant be cracked by any workable means. But the only WPA’s ive been able to crack have been my own simple keys that i have set up to crack, knowing the word would be in my dictionary and so on. For this reason i would suggest rather than slating Purehate or asking for his dictionary list than just give the guy $10 bucks and be done with it, because at the end of the day if your not getting any joy you ither dont have enough patience. Or you dont have a the right list.
He clearly has more computing power than the average user so its more likely he will find your key faster but always bare in mind that the key has to be crackable to be cracked so if you pay $10 and dont get a key its means that the key is secure think about it first. If your doing this to find a key you dont have. Your probably breaking the law anyways if your doing it for any legitimate reason. Then not being able to crack the key is what you actually want! So i would suggest maybe doing it yourself paying the $10 bucks or shutting the hell up. Hello drugs the reason it did not work is because this thread is missing some simple steps(aka it was designed in mind for the average backtrack user) if you notice once you do airmon-ng start wlan0 it doesnt tell you how to get the information for the next window aka your targeted network’s mac essid etc.
You have to run airodump-ng mon0 to scan for networks once found copy the bssid and remember the channel thats the info you use to fill in the deauth attack aka you cant use the same veriables he used in the tutorial but i have verified the Deauth Command works 100% for wpa/wpa2 since its the same encryption scheme and it enables you to crack a 4 way handshake of any rouer on the block doesnt matter the cipher Guide Verified if you know what your doing:) but for noob backtrack users it wont work:).
As the topic suggests really, how many parts and which parts of the 4 way handshake is needed by hashcat to crack WPA/2 and what does hashcat use to crack WPA/2. I only have parts 1, 2 & 3 of the 4 way handshake is that enough for hashcat as i'm finding it difficult to get a full 4 way handshake? I have read that it's possible to crack WPA/2 with only parts 1&2 (possibly 3 too) but i'm also finding conflicting answers!
Regarding which part of the 4 way handshake does hashcat use for it's cracking purposes is exactly that, does it use the MIC from the AP or some other info from the handshake packet? I'm mainly just interested but also for future reference and so that someone else with the same question can find the correct answer in regards to hashcat as i'm guessing that different programs use different but similar ways to process the handshake and crack the WPA/2 key. All answers greatly appreciated. So the beacon should be with those packets I take it?
Would somebody mind taking a quick look at this cap file and let me know if all is there to continue cracking with oclhashcat please? I'm guessing that everything I need is there, the 1, 2 & 3 packets are at the beginning of those eapol packets captured & Pyrit shows the following - #1: AccessPoint 20:0c:c8:xx:xx:xx ('VMxxxxx-2G'): #1: Station 28:18:78:xx:xx:xx, 4 handshake(s): #1: HMACSHA1AES, good, spread 1 #2: HMACSHA1AES, good, spread 3 #3: HMACSHA1AES, bad, spread 2 #4: HMACSHA1AES, bad, spread 5 #2: Station 60:21:c0:xx:xx:xx Here's the cap file - Many thanks Fonzy35 for your response, it's appreciated.

Wireshark the cap file, then you see the beacon that broadcast the SSID, mark toggle that beacon, then filter eapol, mark toggle the eapol 1 and 2 in sequence. Then clear the filter en hit enter, that will bring you back to the full cap file then export specify packets, choose mark packets, there should be 3, put a name ex.: 3packetsbeaconeapol12.cap after that cap2haccp in linux,./cap2hccap.bin 3packetsbeaconeapol12.cap 3packetsbeaconeapol12.hccap works for me every time. Eapol packet need to be in sequence if there are many eapol 1, and 2 m1/4 m1/4 m2/4 m2/4 you take the 2 in the middle that match the same client and ap.You could see a handshake when you did your capture even if someone try to connect with a wrong wpa key.
Best thing is when you can deauthenticat a client that is already connect. check you private message PS don't put the mac address,ssid,hash public. Admin don't like that best of luck.

Admin don't like that best of luck Thanks for that info regarding wireshark, I knew it could be done that way but for the life of me I couldn't remember how to or find info on how to do it!
I have already been trying to crack this network and am about half way through but felt it time to ask in the right place if the cap was any good as I hadn't found anything yet (strange logic I know but hey!) I will edit my previous post and omit the info you mentioned to stay within the rules. Thanks again. (, 10:06 AM)h4x0rm1k3 Wrote: Yes I got that, thanks. I somehow managed to get a full 4 way handshake from the AP, never managed to before so i've followed your directions and stripped the beacon & 4 way handshake frames and converted it to a hccap file to continue cracking from where the other 1 left off. With any luck I should stumble upon the key soon enough and if not i'll go over the keyspace that i've already got through and find it there. Thanks for all your input, I wouldn't have got this far without it!and 'wifite' was another program that didn't always work for me in The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali). So, since you are having a problem with getting a full 4 way handshake, you can follow the process I use below in The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali).
It will also clean up the.cap file for you which you were also having an issue with. It works for me every time. Airmon-ng start wlan0 (puts your wireless NIC into monitor mode) 2. Airodump-ng mon1 (or whatever mon0 it starts for you. Make note of your targets channel) 3.
Airodump-ng mon1 -w /root/Desktop/handshake -c 1 (in a separate console. C = channel to listen on and stores.cap file on desktop) 4.

Aireplay-ng -deauth 0 -a AccessPointMAC -ignore-negative-one mon1 (forces reconnection of clients to capture handshake - it will flash quick in the airodump console!) 5. Wpaclean /root/Desktop/clean.cap /root/Desktop/handshake.cap (yes it's backwards on purpose, cleans.cap to get it ready to convert to.hccap) 6. Aircrack-ng /root/Desktop/clean.cap -J /root/Desktop/ready.hccap (converts cleaned.cap file to ready.hccap file for hashcat to crack. Can rename it to SSID if you want to keep organized) 7. If you don't clean the.cap first, you can see all the network names and if a handshake was captured or not.
