RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - wakawaka - 08-04-2018
how to properly update the old files, I did a "git pull" on hcxtools & hcxdumptool, buts its still not updated ..
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ZerBea - 08-04-2018
Latest update hcxtools (17 hours ago): https://github.com/ZerBea/hcxtools/commit/5d14941d6b5134aea89d9cb43458e858b3c808a5
Update hcxdumptool to 4.2.0: today or tomorrow, because I received many feature requests and I'll try to add most of them. Atom and I doing final tests, so please stay tuned...

RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - espfound - 08-05-2018
Hello Zerbea!
Congratulations on the success of this project and many thanks for your consistent support. At your convenience, please address the following:
a. Does the use of the -N switch in wlanhcx2ssid, to strip an output file, increase cracking speed or reduce the integrity of the file?
b. In a previous post, you wrote about creating more efficient channel scan-lists when probing with hcxdumptool-using wlanrcascan. In theory, what hardware (e.g. actual NIC) and situation would we use channels 14,15....? I'm thinking 5Gz networks, cards and locations.
c. I read your tutorial on WPA Enterprise Networks. The tools you used are deprecated-would you amend this to use your current tool set?
Thanks
Espfound
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ZerBea - 08-05-2018
Hi espfound.
Thanks for the congratulations.
a.
Nearly every wlanhcx2ssid option will increase speed of hashcat, because we reduce the hashes we will feed hashcat with.
But most of them will increase the possibility that we will use a faulty handshake. There are many reasons:
- packet loss of the dumper, not seen by conversion tool
- crappy/no replaycount check by the conversion tool
- no EAPOL timeout check by the conversion tool (there are some tools which assume that the second received packet on a M1 is the correct M2 - also there are tools which zeroes the timestamp; in that case we are not able to detect EAPOL timeout).
If you are shure, the captured handshake is valid, then only one handshake is ok. In that case you will get full hashcat speed. Mostly hcxpcaptool will give you the best handshake.
BTW:
I randomized the ap-less attack to prevent counter measures against us.
INTERFACE:...............: wlp39s0f3u4u5
FILTERLIST...............: 0 entries
MAC CLIENT...............: f0a2255ab3b0 (client)
MAC ACCESS POINT.........: 00234aca3243 (start NIC)
EAPOL TIMEOUT............: 100000
DEAUTHENTICATIONINTERVALL: 20 beacons
GIVE UP DEAUTHENTICATIONS: 10 tries
REPLAYCOUNTER............: 64105
ANONCE...................: a7b5e3f9cdacb546352fc96559f9a3bf7d7f73ba3d3e17a25c28098c65b2e80d
Next hcxdumptool will use the comment field of pcapng EHBs (Enhanced Packet Block) to inform the hcxpcaptool about this (a very good reason to use pcapng instead of pcap, cap). hcxdumptool will save replaycount and anonce value into the comment field of the M2 EPB.
b.
The reason for the duplicates in is simple to explain. We make shure that we are more often on common used channels than on other ones:
- 1,6,11 are most common default channels - so a good scanlist is: 1,6,11,2,1,6,11,3,1,6,11.....
- we can run "frequency overlapped attacks" if we are near of an access point. If we are on channel 2, neighbour channels 1 and 3 are under attack, too. So a good scanlist for that purpose is 1,3,5,7...2,4,6,8
c.
Still we have some om them in the wildness. So there is no real need to remove them.
BTW:
aircrack-ng has wep support (haven't seen wep encrypted networks for a long time here)
reaver, bully and pixie have wps support (haven't seen wps enabled networks or vulnerable networks for a long time here)
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - espfound - 08-05-2018
Thank you Zerbea!
On question c, I am confused WPA/WPA2 Enterprise (radius credentials and so forth). Can you guide on how we can use hcxtool framework for these networks?
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ZerBea - 08-05-2018
hcxdumptool will capture all the required informations and
hcxdumptool is able to detect all kinds of EAP authentications. If hashcat has a correspondending hashmode to recover the password, you can convert the required data easyly, using this switches (hcxpcaptool):
--netntlm-out=<file> : output netNTLMv1 file (hashcat -m 5500, john netntlm)
--md5-out=<file> : output MD5 challenge file (hashcat -m 4800)
--md5-john-out=<file> : output MD5 challenge file (john chap)
--tacacsplus-out=<file> : output TACACS+ authentication file (hashcat -m 16100, john tacacs-plus)
hcxdumptool and hcxtools will follow the crackers (hashcat and JtR). If a hash cracker will be able to crack something, hcxtools will parse it to the hash cracker.
BTW:
This is a nice wireshark filter to take a look inside the pcapng:
wlan.fc.type_subtype == 0x00 || wlan.fc.type_subtype == 0x01 || wlan.fc.type_subtype == 0x02 || wlan.fc.type_subtype == 0x03 || eapol || wlan.fc.type_subtype == 0x04 || wlan.fc.type_subtype == 0x05 || wlan.fc.type_subtype == 0x0b || eapol
We do not need a beacon!

Hello ZerBea
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?
