Great to see you working hard on making hcxtools one of a kind. You guys have left other similar tools way way behind. Hats off and a bow to your tireless dedication.
Q - Regrading hcxpcaptool -o and -O option. Are they mutually exclusive (that is what -o captures -O does not and vice versa) or does -O include all you could capture with -o and then some more handshakes? I mean whats the difference and when to use which option?
see answer in post #275

hcxdumptool 4.2.0 says powned=4 (after having been running for a while) on its status bar;
Is that a spelling mistake?
What does it mean? Does it mean it has pawned 4 networks (how)? If yes how can I see which four are they and what are their passwords?

Select your target and crack the PSK with hashcat

Small update hcxdumptool:
Now we use hardware handshake of the driver. ATHEROS chipset should work, now.
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ZerBea - 08-07-2018
hcxtools and hcxdumptool moved to version 4.2.1
added communication between hcxdumptool and hcxpcaptool via pcapng option field
in SHB and EHB block:
SHB block: 62108 REPLAYCOUNT uint64_t
SHB block: 62019 ANONCE uint8_t[32]
EHB block: 1 "HANDSHAKE AP-LESS" (green field in Wireshark Packet Comments)
EHB block: 62109 ANONCE uint8_t[32]
hcxdumptool: new status display options
ATHEROS still not working like expected.

RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - MadMeow - 08-07-2018
Good day, Zerbea.
First of all, i want to thank you for extremely useful set of utilities. Excellent work! I use your utilities from the very beginning of development and i always happy with results.
I had several questions now related to new version of hcxdumptool.
1. I faced that the utility ceases to work after a while. I am connected to Raspberry (3 with Raspbian 9 kernel 4.14) through ssh and i watch that how many packets it was received by the radio interface. After a while works of the program i notice that when switching to the following channel the number of collected packets (rx) increases by only one packet and at the same time transfer of packets stops. I can start the program again, but it does not help. Also the stop and start monitor mode (i use Atheros in TP-Link 722N) does not help. After reboot for some time everything becomes normal, but then the situation repeats again. I was updated about 8 hours ago. Can you tell me what I can check to localize this problem?
2. I tried the new attack mode and it really works great! I would just like to clarify some details about the output format of a file that contains PMKID. When using Hashcat (16800), I noticed that several APs with different MACs, but the same ESSID and pass were restored (of course it could be CAPsMAN or similar, for example) and i had some doubts as to whether i correctly understood the format of the pot file. Correctly I understand that the second position in the pot file after "*" is exactly the MAC address of the AP, which was successfully attacked?
Forgive me for my bad English and Thanks in advance!
Update:
The second question is removed from the agenda, i managed to repeat the situation in the lab.
Now i have updated to the latest version of the utility (4.2.1) and after building a new system image for Raspberry, it seems that i do not observe what i described earlier. Is it possible that there were some performance issues? In any case, i will try to reproduce this problem.

Hi MadMeow.
First of all, thanks. I am very pleased about that.
1.
I'm not shure, how to handle the TL-WN722N. I noticed some issues in handling the FCS. You can read more about that here:
https://github.com/qca/open-ath9k-htc-firmware/issues/126
https://wikidevi.com/wiki/Wireless_adapters/Chipset_table (do a search for "broken")
https://github.com/vanhoefm/modwifi/issues/9
https://github.com/ZerBea/hcxdumptool/issues/12#issuecomment-410726219
(https://forums.The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali).org/showthread.php?34265-K a l i-linux-2016-2-amd64-problem-AWUS036H-wifi-card&styleid=2)
Sometimes the delivered packets (from userspace via raw socket to driver) are cut by the driver (last 2 bytes - I assume that is the FCS). After a while, the driver crashes. You can reproduce this using Wireshark. Wireshark will show you many "Malformed Packets", even if hcxdumptool is not running!
2.
Format of the 16800 potfile:
PMKID*MAC_AP*MAC*STA*ESSID followed by the PSK
Format of the 16801 potfile:
PMKID*MAC_AP*MAC*STA folowed by the PMK
If you have more hashlines with the same MAC_AP (BSSID) you can remove all, except of one. THis will speed up hashcat a little bit.
Using Version 4.2.1 you will notice some improvements:
--enable_status=<digit> : enable status messages
bitmask:
1: EAPOL
2: PROEBEREQUEST/PROBERESPONSE
4: AUTHENTICATON
8: ASSOCIATION
For example to retrieve EAPOL and PROEBEREQUEST/PROBERESPONSE you can use
--enable_status=1 --enable_status=2
or via bitmask
--enable_status=3
status out will show you:
[FOUND HANDSHAKE AP-LESS, EAPOL TIMEOUT 11132]
This Packets will be marked green in Wireshark.
[FOUND AUTHORIZED HANDSHAKE, EAPOL TIMEOUT 2129]
[FOUND PMKID]
[FOUND PMKID CLIENT-LESS]
or if hcxdumptool restarts the authentication sequence between a client and an access point
[EAPOL 4/4 - M4 RETRY ATTACK]
if you get more of this messages, you are too far away from the accesspoint.
--enable_status=2 will show you possible PSKs retrieved from the traffic, as well es ESSIDs.
Also we do a measurement of the EAPOL key timeout.
High timeout means: much traffic on the channel or weak signals

RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - MadMeow - 08-08-2018
Thank you very much for your help, ZerBea.
After some field tests, i think the problem really is with Atheros driver (I really miss my broken Alfa with 3070). But if I run the program with a "--disable_ap_attacks" key, then this problem does not happen. There is one more observation. If i do not use additional parameters, but simply specify the interface and output file, then the program works without problems if there are not more than half a dozen access points around. As soon as i start the program in a place where the radio air is very busy, after a while problems begin. I can not even connect to the ssh until i disconnect my adapter from usb, that causes hcxdumptool to stop working and after that i can connect via ssh again. I can still capture PMKID from the access point to client, but i do not initiate this process through hcxdumptool.
With my second question, everything is very clear to me. I'm really clearing the file manually to reduce hashat worktime. In my case, I need all MAC for my personal database and I just wanted to make sure that there is no error. This really can happen if I stumble upon Mikrotik CAPsMAN or access points that automatically organize a single wireless infrastructure (like some Asus models, for example).
Once again, thank you for all the information and I wish you great success in the development of your project.
Update: Oh. I must try new version now, i think.

Hello ZerBea,
seems AP's with special characters (" ' * ) are auto converted to $HEX[xxxxxxx] in PROEBEREQUEST/PROBERESPONSE.
is this something that can be fixed/added in a future release.
