And I have yet to see a WPA-2 Access Point in my area. O.o - Yazoo, on 09/14/2008, -1/+35You will need to be running a very special distribution of linux, known to only a few groups of people, dotted around various tropic rainforests, furthermore, you will need to install this on a pentium 1 266mhz with EXACTLY 16mb of ram, nothing else will work. Given that you have installed the very spacial distribution of linux a green elf will visit your house precisely 2 hours and 26 minutes after the soup you have earlier prepared is ready. Give him the soup, and let him sniff for the wifi you want to hack. He (if it is a female, run!) will give you an envelope filled with lettuce, and written on the inner most leaf you will find a hexadecimal cypher which you will need to translate into ASCII. This code you will then need to yell loudly at the special wolf that will arrive soon. When you have done this, click F9 on your keyboard of your new linux PC, and the keys for all the wifi networks in your area will be sent to you. Easy.
- ElBeh, on 09/14/2008, -1/+28Well, the internet runs on a Linksys WRT54GS
- aksn1p3r, on 09/13/2008, -2/+17I hear stories of people's accounts being over-used and then it gets capped, just cos of wireless hacking leechers!
- synystar, on 09/14/2008, -1/+16You have RADIUS at home? How many people are living with you? And with MAC filtering what's the point of RADIUS? Also .. an 18 year old geek chick from CA who joined digg yesterday? I'm not buying it.
- synystar, on 09/14/2008, -1/+12Dial-up may be dead, but wire is not.. Your cable and DSL lines are very easily accessible.
- diabolicedict, on 09/14/2008, -1/+12Here is the summary.
Use WPA2 or WPA. Do not use WEP unless the only other option is not having any encryption at all. WEP is crackable in under a minute. - tonich03, on 09/14/2008, -2/+13I'll be sending your comment to the internet Grammy's.
- synystar, on 09/14/2008, -1/+11(for me) .... WEP keys are hackable within minutes by anyone who knows how to use the Internets. Anyone who understands what they are reading anyway.
- verkon, on 09/14/2008, -1/+10Oops, ars technica forgot to put the L in WLAN.
Before you bury me and say that I am wrong, just wanna let you in on a secret.
WAN stands for Wide Area Network, e.g. the internet, now WLAN on the other hand is wireless local area network and is what the article talks about.
I'll be leaving now. - LeviTheSmith, on 09/14/2008, -4/+12Send me pictures to prove you're a girl.
You have to PROVE it if you know what I mean.. ;) hehehe - drex8, on 09/14/2008, -1/+8Why? MrsBabyMan or MissBabyMan was taken?
- PabloMac, on 09/14/2008, -0/+6Dugg for "if it is a female, run!"
- joshualamgroup, on 09/14/2008, -1/+7no, it's called aircrack-ng bro.
- inactive, on 09/14/2008, -2/+7you mean you can get around barnes & noble's and at&t's pay for access bull *****?
- MacBookForMe, on 09/13/2008, -3/+7You are hot, mate! (that's why I am still using wire, instead:)
- fishpen0, on 09/14/2008, -0/+4I have a cap on my bandwidth and I am not going to let someone else use it for free and force me out of having internet at the end of every month.
- Andy.D, on 09/14/2008, -1/+5This is a good primer on wireless security. Should be good enough to send to the noobs running with their Linksys SSID.
- Zerophnx, on 09/14/2008, -2/+6We paid for the hardware and bandwidth. Leechers get off without paying a thing.
It's a matter of protecting an investment, like a lock on a house, you don't just want people to walk in and start using your possessions. - ElBeh, on 09/14/2008, -0/+4I don't think you got the reference.
- inactive, on 09/14/2008, -0/+4I love my Linksys brick!
- Kotori146, on 09/15/2008, -0/+4You do realise a hidden SSID provides no security what so ever? Your network can still be seen it just had no name given to it.
- alexmuller, on 09/14/2008, -2/+4The most interesting part of this article is that it makes me wonder what's going to happen in the future - can anyone else see a time where Wi-Fi is globally ubiquitous and unsecured, and we pay for what we use? Except this time, it's decently priced...
- Zenshai, on 09/14/2008, -0/+2That is the worst introduction to a "professional" article I have ever seen. I mean even for "technical" writing, that was just horrible.
- 471776, on 09/14/2008, -1/+3http://xkcd.com/416/
- feckit, on 09/14/2008, -1/+3I take it most people are talking about their experience with WLAN's in the US, because where I live outside London I can see 12 wireless networks and all but one of them are using WPA or WPA2. I have to say that having that one network which is totally unsecured is handy because when my ISP has problems I can check the status over that network (so I know if its "just me" or not) ...
- Zerophnx, on 09/16/2008, -0/+2Source and Destination address refer to the IP address. MAC addresses aren't used outside of the local network. There are null MAC addresses in packets like FF:FF:FF:FF:FF:FF. But obviously that piece of information won't get you anywhere.
That IP on the other hand.... - QuimbyDogg, on 09/14/2008, -1/+3If you allow any user on your network a simple ARP hack attack and they can view all of your incoming/out going traffic. That includes any unencrypted passwords you use (many websites/email/ftp). You would be amazed how many basic Internet protocols don't use encryption for passwords.
Putting a lock on a wireless network has little to do with keeping people from using your bandwidth and very much to do with protecting your privacy.
I took my linux notebook over to my friends apt one night when I was spending the night. In about 5 minutes from the time I connected to the network I was able to monitor his AIM conversations -- even read profiles that he was viewing. - DougVitale, on 09/22/2008, -0/+2FTA: "But what if I had told you that, in eight years, all the major methods available for securing your wireless network would be known to have major flaws".
So what are the "major flaws" associated with using WPA/WPA2 with strong passkeys? I have never heard of any and ArsTechnica certainly doesn't elaborate. They even admit that "home networks don't have much to worry about here (with WPA), provided your authentication key isn't something along the lines of 'cat'." The article isn't terribly "in-depth" either, but I'm digging for the section on the refutation of common wireless myths. - BRODEL, on 09/15/2008, -1/+3The only method I know of is a brute force attack and if you use a decent key (60+ *random* ASCII characters), the chances of cracking that are very slim. Yes you can capture some traffic and do an offline brute force, but with two of my neighbors running unencrypted and another using WEP, I don't think you'd bother with mine.
- geeshock, on 09/18/2008, -0/+2But there are those that use simple words as the key and take under an hour to use a dictionary attack against (no rainbow tables, word lists).
- TheOther1, on 09/14/2008, -0/+2My bill will be $0 if it's unsecured...
- inactive, on 09/14/2008, -1/+3if you can do packet injection and have reasonable tools WEP takes less than 60 seconds.

http://ftp.c3d2.de/camp/camp07/cccamp07-en-1943-Br ... - QuimbyDogg, on 09/17/2008, -0/+2MAC addresses are stapled on to all internet traffic, period. Anyone who has formal training in how network traffic works knows there are multiple formats of transmission which go with the multiple layers that make up a network (7). Information is not just dropped into an IP packet and that it is. Look up ethernet frames. That is where your MAC address information is stored. Ethernet frames encapsulate the IP packets that are formed at a higher logical level. The ethernet frame is the information that is actually transmitted "on the wire." MAC information can be tracked. It is there for a reason, if it wasn't used for traffic there would be no point having an address scheme besides IP...... The Internet uses both IP and MAC addressing to get your information where it is going by adding information as it goes down (from the application layer) to stripping information off as it goes up from the physical layer. While the MAC of your router is what is put on traffic going on "the big wire in the internet" that router is keeping track of all the MACs associated with it as well -- you don't think that data would be confiscated by the RIAA when they take your computer?
If anyone actually cares enough about this issue they can spend 30 - 60 minutes on wikipedia reading about the different layers of the Internet and how traffic is created going from the application layer all the way down the physical layer where it is put on the wire, how that is received and then unpacked. - rfquinn, on 09/14/2008, -0/+2FTA: "all the major methods available for securing your wireless network would be known to have major flaws, and that there was pretty much no way to keep a truly determined attacker off of your WAN"
Ummm....This is the first time I've heard that WPA2-PSK using AES was crackable. (With a decent key length)
Anybody care to chime in? - QuimbyDogg, on 09/14/2008, -1/+3I am currently working on my masters in computer, information, and network security. It really is insane how easy it is to attack any network people "think" is secure. Having a few computers it is relatively easy for me to setup my own test networks and try breaking into them. A WEP encryption on your network is as good as leaving it unprotected. Hiding the SSID will not help either as any "real" scanning tool will still find the AP.
I spend a lot of time at friends apartments in Chicago and it is easy to find 10+ AP at once. My general finding is that the majority of them are secured---but just by using simple to break WEP. If you truly want to be protected you have to stay wired. - inactive, on 09/14/2008, -1/+2That is most likely done by a Radius server, to which then you will have to brute force...
Or just pay up to "the man." - hojibuji, on 09/23/2008, -0/+1you don't know what the hell you're talking about QuimbyDogg.... your CCNA does NOT make you a internet or networking all star...
- hojibuji, on 09/23/2008, -0/+1that's WPA, not WPA2
- hojibuji, on 09/23/2008, -0/+1what university are you getting your masters degree from? based on your previous comments, I'm skeptical of the training you're receiving...
- Stevo23, on 09/14/2008, -1/+2You're just flat wrong. MAC addresses are not part of internet traffic. They'll only show up in your own server logs (and then only if you keep them).
- BRODEL, on 09/15/2008, -1/+2It's the opposite here. You would have 10 unsecure, 1 WEP and one WPA.
I recently had a discussion with one of the security guys where I work about wireless and he mentioned that his was secured using MAC filtering and I tried to convince him that wasn't really secure and he pretty much said it's good enough. :(
I'm just glad he's not in charge or the wireless at the business sites. - Plxply, on 09/14/2008, -0/+1Elbeh did fail to be digg standards complaint and add a sarcasm tag. You know just for the "slower" people out there. /sarcasm
- BRODEL, on 09/15/2008, -1/+2I thought the same thing when I read that glad I'm not the only one wondering what they're talking about.
- nrox653, on 09/15/2008, -3/+3The DS forces people to stick with WEP, unfortunately... So people who play online are kinda stuck.
- Stevo23, on 09/14/2008, -2/+2Hence the word "throttle" you stingy bastards.
- calidor, on 09/14/2008, -1/+1Still crackable with a decent computer and good rainbowcrack tables
