Troubleshooting KisMAC

KisMAC 0.3+  Bugs
KisMAC 0.3+  Issues
KisMAC 0.3+  Not Working

KisMAC 0.3+  Bugs, KisMAC 0.3+  Issues, KisMAC 0.3 Not Working

-Did you noticed that KisMAC 0.3 is for Snow Leopard 10.6 ? and not for 10.5? ok....

Can't Scan with KisMAC 0.3

"NOTE: If a previous installation of KisMAC has been used, please make sure to delete the following files,  if they exist:"  ( '~' is your home folder) (Using App Cleaner IS a GOOD IDEA)

  • ~/Library/Preferences/de.binaervarianz.kismac.plist
  • ~/Library/Preferences/com.kismac-ng.kismac.plist
  • ~/Library/Preferences/org.kismac-ng.kismac.plist


Message
Could not instantiate driver. KisMAC has not been able to load the driver backend
Could not initiate driver. KisMAC has not been able to……












Whatever you do, if you have an injection device (WIFI card or USB Adapter)
DO NOT install the drivers of the card / USB adapter unless you have read this post

Possible causes:
You have NOT selected "Use As Primary device"
You Have NO Drivers selected
You have Selected the wrong one
Your Chipset is not supported (see Hardware list)
The Chipset of your USB Network Adapter is not correct (See FCC Number)
In order to avoid those issues => Best Wifi Card for KisMAC

If you look in your console.log (Spotlight >> Console)
you'll probably see a lot of lines with KiMAC as "sender" and an error messages such as:

KisMAC[2928]    vendor 1452 vendorId 3574 product 32773 productId 38674
KisMAC[2928]    Matching finished
KisMAC[2928]    Error could not instantiate driver WaveDriverUSBRalinkRT73
Reading the last line, you can easily guess where the issue comes from: RT73 driver can't be loaded. Why? because you specified to KisMAC not to, or Specified to KisMAC to load the wrong one.
Solutions
Select Appropriate Driver or use the proper USB Network Adapter. You may need to Force Quit the application
You have installed drivers provided with the CD of your USB Network Adapter.
Solution 1:Time machine? if you have Time Machine set up, pat yourself on the shoulder: smart guy!
If not, time to think about it and move onto Solution 1.5

Solution 1.5:
Uninstall the drivers* and the all shebang provided with your injection device
including the proper .plist for Kismac
use AppCleaner to remove all .plist
OR if you had a previous install, remove the following, if any:
~/Library/Preferences/de.binaervarianz.kismac.plist (where '~' is your home folder)
~/Library/Preferences/com.kismac-ng.kismac.plist (where '~' is your home folder)
~/Library/Preferences/org.kismac-ng.kismac.plist (where '~' is your home folder)
(told ya' use AppCleaner)

Solution 2: If, after uninstalling the drivers*, the problem persist, -and- you have trouble with your Airport Extreme, you may be in for a shitload.
Uninstall KisMAC, and re-install


Injection does not work
- Check that your device (USB/Card) is able to inject,  => see Best Wifi Card for KisMAC
- Test injection: Tab “NETWORK” >>>”Test injection”









- Check that you have checked the box “use as primary device” in tab Preference >>> Drivers
- Check that you have the proper driver/chipset selected i.e. USB RT73 or USB RT2570 (Preferences >>>Driver)
- Check that proper channel is selected. One channel only: You cannot inject while Channel hoping is selected

- As stated, be very careful to have the proper chipset, otherwise: nada!
Word of advice, I would suggest you to test the hardware in a “brick and mortar” shop before you buy something that will not work, or take my word and experience for it, and purchase the best card available for KisMAC, it's less than $35 and allows you to get a signal up to 1 mile. it's 20x more powerful than an Hawking.

Reinjection Not Working

If you have tested the Re-injection and your card should re-inject packets, you may have the following issue(s)
- Your card is not powerful enough for the signal to reach the AP => get this one: Best Wifi Card for KisMAC
- There is not enough "good" traffic on the network. IV's (Initialization Vectors) are only about 5% of good traffic.
You also have the remote possibility to have encountered a very rare breed of APs: The one equipped with "WIPS" (Wireless Intrusion Protection System). In that case, Passive Mode is the solution.

If you want to know more, here is an excerpt from the KisMAC FAQ.

"What is packet reinjection?

802.11 requires frame retransmissions in the case of loss, so it may be possible for an attacker to retransmit a frame and replacement injected frame to be accepted as legitimate. Frames on wireless networks can easily be tampered with or forged outright, and the protocol does not provide a way to easily stop or even detect such attacks. Acknowledgment (ACK) and Address Resolution Protocol (ARP) are the management frames that are likely to generate responses from the client and AP

Packet reinjection is a very advanced WEP cracking technique. Be aware that this is the bleeding edge of technology, so it might not work every time. When you use this attack, KisMAC will try to find packets that will cause another computer to respond. The program will then send these packets over and over again. If KisMAC detects answers, it will go into injection mode.....   Please be aware that all detections are of a heuristic nature, therefore it might not always be working" 
Source:  KisMAC


Packet collection is very slow
It’s probably because the network is not very active (low traffic). Just go on YouTube, watch few videos and the packet collection should increase very quickly.

Crack does not work
-Well, as stated in the FAQ, Injection is the bleeding edge of this technology, and I have experienced myself some failures with my own network: I was unable to crack my own key with more than 1,000,000 unique IV’s.
Other possible causes:
The key was changed during the collection
You have selected a 40/64-bit WEP when the key is 104/128-bit WEP, so in doubt, play safe and select both
You have encountered a SOL error: Shit Out of Luck

The wpa key could not be recovered because of the following reason:
the key was none of the tested passwords.."

Most likely, your dictionary file does not contain the exact password, read the article about wordlists.


WPA Reinjection Does Not Work
please note that RE-Injection and Injection are not the same. 

-WPA RE-injection will not work, you can only RE-inject on WEP network, if you have an injection device.  (i.e When you Deauthenticate , you are injecting frames)

KisMAC Crash on WPA Wordlist
KisMAC Can't Perform Injection Test
This is bug with KisMAC 0.3.3 while on 64-bit
Go to Applications >> KisMAC.app >> Get Info
Check "Open in 32-bit Mode"  and restart. 
 


Could not load Airport Driver

KisMAC could not attach to the Apple Airport Driver



This Error Can Have Multiple Origins,  Please Read Carefully.

 KisMAC could not attach to the Apple Airport Driver
 In Preferences >>> Driver
You may not have selected any Driver  (Apple Extreme, RT73, etc etc )and pressed the "Start Scan" button multiple times, this provokes a freeze and return this error.
The "Start Scan" button looks like the one in the picture below (button engaged)
The solution is a Force Quit and to select a correct driver in Preferences >> Driver













KisMAC could not attach to the Apple Airport Driver
Cause: Airport, Airport Extreme in ACTIVE Mode
This issue is fairly new and is related to the brand new Snow Leopard (10.6)
You have this error because you have selected Active Mode
Close KisMAC , re-open and select Passive Mode.
Do not use Active Mode with OS X 10.6 until further notice.



No Driver Selected
Please Select a WIFI Driver










Go back to Preferences and Select a Driver
i.e.  Airport Extreme Passive Mode, USB RT73 Device, or else.

KisMAC Ch/Re Gem
The Ch/Re Gem is situated on the last  column, right after "last seen"
Ch/Re stands for Challenge / Response
 The Gems have 3 colors possible: Green, Orange and Red and the meaning will depends on the type of encryption of the Channel/Network
 





Enc = NO 
The Network has no encryption (Open), (under column "Type") the Ch/Re Gem is green by default
Enc = WEP
The Network is encrypted by a WEP key, the Ch/Re Gem is red by default and indicates that Kismac does not have recovered a key (yet)  No Challenge or No Reponse
Green Challenge or Response
Orange  has a Challenge OR a Response
Enc = WPA
Red: No handshakes captured, don't even try a wordlist
Orange:  Capture Started (?)
Green: Handshake Captured


KisMAC Freezes
KisMAC Hangs 

KisMAC Freeze, KisMAC is hanging, KisMAC Freezes, PinWheel KisMAC

If KisMAC Freezes after few seconds, and hangs (Pinwheel) the first cause that comes to my mind is that you are using (listening to) the wrong channels. 
If you are in USA, you should not be using Channels 12,13 & 14 (Europe and Japan)
If you are in Europe, You should not be using Channel 14 (Japan Only)

Just uncheck 12,13 & 14, that should resolve the problem. 

Possible cause: Channels 12,13 & 14 are close to the microwave range and cordless phones (old ones)
It's possible that you are listening to your coffee or pop corn. 
A second cause could be a large number of router using the same channels (often Ch 6), it may also create issues on your own network. In that case, just switch channels and you'll see an improvement in your Network quality

Can't Collect IV's
Can't Collect Packets
Packets Collection is very slow

I have received a lot of questions about this issue. The most probable cause is a non active network.
A non active or slow network (low traffic) is what makes the collection very slow.
KisMAC in passive mode is like trying to collect rain water: The more it rains, the more you can collect. That simple! If it does not rain .... or very little ... you got the idea!
A good wifi card will help you solve this issue

After receiving 10 + questions on the subject, here is an example of a near silent network:










As you can see 614,847 management packet (beacon) and only 25,945 Data Packets (the good stuff)
so, 615,902 junk.
This network is simply "on" but not used, hence, as long as there is no valid traffic, you need to be more than extremely patient 

Other possible cause: You may be listening to a Probe, or a Router not connected to the internet, or someone that left his router on, but does not use it.   Read the post till the end... 

Here is what I have tested with active networks, and very active networks. It clearly shows that the collection of IV's is related to the traffic. 
The test is with an Airport Extreme, Passive Mode,  NO Re-injection
It took me 5 minutes to reach 130,000 IV on very active network, and 126 min on Active.
For the numerous persons that still believe that Kismac can not crack on Airport Extreme, the following is going to be surprising: 

Very Active Network
Time : 0:02:05  2min, 5 sec
Bytes: 83.42 MiB
Packets 58,423
Unique IV in 0:02:05 = 57,016
U IV/Sec  = 456.12 
Theoretical Time to reach:
130,000 = 285 sec = 4.75 min
200,000 = 438 sec = 7.30 min
300,000 = 658 sec = 11.0 min

Active Network 
Time 03:23:50 3hrs 23 min 50 sec
Unique IV's in 03:23:50 = 210,216
U IV/Sec  = 17.18 
Theoretical Time to reach:
130,000 = 126 min
200,000 = 191 min
300,000 = 285min



1 As Kismac has loaded the Airport Driver, he has control over it. Proof that this is on Airport and not on USB
2 Time
3 Packets
4 Unique IV's Collected with Airport Extreme on Passive Mode.













a  Kismac still on Airport
b Time  2min and 5 sec
c Unique IV's Collected with Airport Extreme on Passive Mode. = 57,016 in 2 minutes, roughly 11 min to 300,000
d Bytes = 83.42 MiB for 57,000 IV's












Hence, Kismac does work on Passive Mode, and yes, you can crack on Passive mode without Re-Injection. If you can't, it's probably because of the network quality or simply because you may have selected a wrong parameter.


Test Your Own 
One way to be sure is to test your collection speed: 
Go to a friend's house , Start KisMAC , and ask your friend to watch multiple Youtube Video on its network. You want to push the router to the max. 
You'll be then able to see if the issue is due to slow network or not. 
While you're at it, ask your friend to run KisMAC too: You'll be surprised to realize that you can: 
A) exchange PCAP dump files and try multiple cracks on multiple networks
B) if using Re-injection, notice that ONE device will make ALL Macbooks able to pick up the responses


Macbook does not detect edimax ew-7318usg

It's NORMAL!  Don't panic!!!
Your Macbook can NOT detect your Edimax, because your driver(s) are not installed.
KisMAC will detect your edimax, under Preferences >> Driver >> use USB RT73 Device
DO NOT INSTALL the Drivers provided with the install CD of your Edimax unless you have that!
if you do so, or have done so, please refer to Troubleshooting KisMAC. 
  
Kismac weak scheduling attack takes a long time
A Weak Scheduling attack may take some time, but you (yes, YOU) can make much faster:
Don't start cracking unless you have a mini of 130,000 IV's 
200,000 is recommended 
You may have collected corrupted packets, Sorry: S.O.L , try again
Rule of Thumb: The More IV's Collected, The Faster The Crack Will Be.

Another solution is to install Aircrack-ng:  Collect packets (collect or re-inject) with KisMAC, Crack with Aircrack-ng: it's 10 X faster
How Many packets I need for WPA? 
None! For WPA,  you need to capture the Handshakes.
Look at the Ch/Re Gem indicator , or read the post related to that question. 

How Many unique IV's for WEP? 
Number of unique ivs needed kismac?
KisMAC: It is recommended to start at a minimum of 150,000 unique IV's
You can always try under, but it will probably fail or the key recovery may take much longer.
Aircrack-ng:  As little as 40,000  20,000

How fast can I successfully crack a WEP or WPA?
How fast can you crack a WEP key?

You just opened a can of worms ...
WEP
KisMAC: The more IV's you have collected, the faster the crack should be.
I have successfully cracked my own WEP key in less than 3 sec (128 bits key)
I also have, on the same key, spent hours with no success, .... I had up to 2 millions IV's
I suppose some frames were corrupted, but I can't say for sure.  I made a Video on YouTube showing a crack in less than 3 seconds.
Aircrack-ng: 1 second on a 64 bit key with 40,000 IV's 

WPA
It will depend on your password. If you use a dummy password*: between 5 sec and few hours.
If you use a GRC generated password, you better explain to your kids how to do it: they will continue your work long after you'll be dead.  Seriously!

If you NEED an internet connection because you just moved, are in a new place, can't afford the monthly overpriced FIOS or UberDuper connection, then you'll need a SA-6p, SA-12PSA or SA-24PO
it's not software anymore, it's hardware, but I was successful in cracking a WPA2 in very, very, little time.  
I have heard of BIM attack with Ha100B series, but I never tried it myself.

BTW: Dummy passwords:  lists ARE available :-),  I URGE you to use very serious password and avoid at any cost guessable passwords such as: 123456, 1234567, password, letmein, mustang, iloveyou, etc etc ... 

PCAP Dump
When you check the box "Keep everything" it start saving a file where a bunch of details are kept.
This file is accessible for later review (advanced user only, please) you can use Wireshark to read that file and discover all the little tiny details ;-) 


Console Log  (from Console.app)
it's the log of what is happening behind the doors when you use your computer.
If you keep console log open, you may find messages such as "Warning, deauthentication Frame received"
It means that somebody is trying to penetrate your network with a Deauthentication attack. (more exactly, trying to force capture the handshakes)

The magic of the Mac is back! Mac OS X is a truly revolutionary operating system that has great flexibility and functionality. Free download Upgrading and Troubleshooting Your Mac(R) books collection in PDF, EPUB, FB2, MOBI, and TXT formats. Author Gene Steinberg shows readers how to tap techniques of IT professionals to make your Mac run at top efficiency.Gene Steinberg understands that the new Macintoshes--like all computers--are systems of hardware and software, and that neither may be separated from the other. Upgrading and Troubleshooting Your Mac: Mac OS X Edition is an intimate picture of modern Mac hardware (the Power Mac, PowerBook, iBook, and iMac platforms) and the points at which it interacts with Mac OS 9.1 and Mac OS X. Best deals ebooks download Upgrading and Troubleshooting Your Mac(R) on amazon.As you'd expect, readers learn how to select and install add-in hardware like SuperDrives and supplementary RAM, but the Mac makes those procedures pretty easy by design. The real value in this book comes in two areas.First, Steinberg answers all kinds of common, but officially unaddressed, questions. Is it absolutely safe to put your laptop through an airport x-ray machine? How does a G4 behave when a SCSI card is malfunctioning at the hardware level? What happens if you try to make an officially unsupported graphics card work? Do third-party processor upgrades work? He explains most of these matters with stories taken from his experience as a longtime Mac user.Second, the author knows a ton of tricks for working with the Mac OS itself, and is liberal with his recommendations of utilities for diagnosing, repairing, and adjusting its behavior. His thoughts on how to solve problems by reinstalling your operating system without wiping out your installed programs will save you time in all but the gravest situations. You'll find this book particularly valuable if you do upgrade and repair work on unfamiliar Macs. --David Wall Topics covered: Changing and adjusting hardware on modern Macintosh computers (PowerBooks, iBooks, iMacs, Power Mac G4s, and, to a lesser extent, Power Mac G3s). All the key subsystems get attention: monitors, networks, SCSI chains, FireWire peripherals, and hard drives. Special (and especially valuable) coverage of Windows emulators and video capture hardware appears as well.

With sales climbing once again, Apple has made an incredible comeback. Free download Upgrading & Troubleshooting Your Mac books collection in PDF, EPUB, FB2, MOBI, and TXT formats. This guide to upgrading and troubleshooting the new Macintosh computers includes a CD-ROM with a suite of diagnostic software to help solve problems quickly and easily.'Upgrading & Troubleshooting Your Mac ranks among the best technical books about the Macintosh around. Representing a distillation of the knowledge author Gene Steinberg has gained in his lengthy consulting and writing career, this book reveals details that everyone can use. Best of all, Steinberg explains the workings of the iMac, iBook, PowerBook, and Power Mac G3/G4 in a way that's easy to follow and fun to read. Best deals ebooks download Upgrading & Troubleshooting Your Mac on amazon.He glosses over the most basic Mac operations (the stuff that's usually obvious anyway, like moving files around) and covers all sorts of intermediate- and high-level tricks. He even explains stuff that you might have thought was the exclusive domain of professionals, such as setting the white balance of your video display and setting up a network so that Macs can store files on Windows machines and vice-versa. The author's presentation style emphasizes "why" over "how," so while you will find quite a few no-nonsense procedures here, you'll probably get more out of his explanations of alternative ways to proceed and strategies for avoiding trouble ("A Handy Guide to SCSI Voodoo" is the title of one section). Steinberg's case studies and notes from his consulting experiences make great reading too. The net result is that it's very likely you'll be able to find something--probably quite a bit--on any Mac problem you may encounter or improvement you'd like to make. --David Wall Topics covered: Getting the most from Mac OS 8.x and 9. Error messages, hardware upgrades, printer configurations, fonts, SCSI, networking (including heterogeneous Windows/Mac networks), scanning, Internet access, and display setup.
