hack wifi password,So simple!

The one about the hack wifi key do not see a friend, please open http://www.wifirobin.com/29574keyHack wifi password here to talk about the whole process:
WPA encryption for wireless environments, access to the WPA handshake authentication package, the attacker will break patterns of violence carried out by WPA password cracking, but also can be targeted by the prior establishment of a dictionary, and then break for a dictionary (attack). For most wireless access point AP, this would be a very efficient way. Because of the fact that: most of the administrators, maintenance personnel, safety awareness among home users do not think so high of their own, at least in the past year or so, the author has encountered numerous birthday or simply set to WPA word -PSK password.

So, is it can be said that as long as there is enough space, consider the comprehensive dictionary, crack the WPA key is actually also a matter of time. Really just a case? Do not know too careful attention is not, according to the current mainstream stand-alone environment configuration, the rate on crack WPA also maintained at 100 ~ ~ 300k / s (k / s refers to the break key when the second call number) in order to break this rate, should be a combination of lowercase letters and numbers 5 WPA password breaking open, we come to estimate the basic knowledge about probability theory:

(26 +10)? = 60466176;

Break all the time will be:

60466176 / (3600 × 300) ~ ~ 60466176 / (3600 × 100), which means that 55.987 ~ ~ 167.962 hours.

If the number of conversion all day, then takes about 2 ~ ~ 7 days. It also only 5 digits WPA password, and in fact, 5-digit WPA key in today’s most wireless routers do not exist inside the minimum is 8. If using WPA password as plain lowercase letters and 10 digits in length or more, you need the fastest time is 5,446,261 days, which is 14,921 years!! Really is day-digit ah!! If password combination using uppercase and lowercase letters + numbers + special characters, then I am afraid that here you will say: or do not consider the break up, right? Therefore, access to the front about the WPA handshake to carry out the break was actually only a simple password in the other case, that is, said that because of crack speed is too slow, so use a little more complex in each other’s password, the conventional method not much actual combat ability, and even break completely lost meaning. Was estimated using lower case letters and numbers in the 5-digit password, in the single to 30k / s rate of crack need time to 24 days. Some people may think, can not raise my hardware configuration to increase the crack speed? Yes, this is a viable option, but for now, the most common memory is also under an independent computer will be able to upgrade to 4G, CPU nothing more than the latest high cache quad-core processors. This configuration for the example we have 10-bit WPA password, break time is calculated in years!

Was first hit about retracted it, do not want to see again not imagine what will happen.

However, there are individual expert can use the family computer in a very short time, break out some of the wireless network, WPA key, which is what do?

Here we break open a high-speed before about some of the concepts:

Tables

The password can be long-term study, very few are not aware of that. Many years ago, foreign hackers discovered simply by importing the dictionary, using the same Suanfa break and objectives, its speed is very slow in terms of efficiency can not meet the actual needs. Through a large number of attempts and after the conclusion, hackers have found that if the direct establishment of a data file, which targets pre-recorded using the same method used and the calculated hash value generated in the Hash, the time needed to break such a file directly call for comparison, the efficiency can be significantly cracked, or even hundreds of times to raise nearly near, so pre-constructed data file Hash hash called in the security sector, Table table (file).

Rainbow Tables

Tables are the most famous Rainbow Tables, the security sector, often referred to rainbow tables, it is based on Windows user accounts LM / NTLM hash to crack the object. Briefly, in Windows2000/XP/2003 system, the account password is not explicitly saved, but the algorithm defined by Microsoft, save as a file can not be directly identified, known as the SAM file, this file work in the system because it can not be called directly break. But we can be a way to extract hash Hash is to facilitate the import into the professional tool crack, extract the password hash is similar to the following:

If the traditional hack, whether local or line break within the network, the efficiency is not very high. According to the actual testing, stand-alone environment, breaking a 14-bit long number of uppercase and lowercase letters and non-law code, usually takes 3 ~ ~ 9 hours, this time value as the password complexity and improve computer performance difference to the a few days or even months. Although most people will not use such a complicated password, but complex enough for now and a lot of password length of more than 10 passwords such as “Y1a9n7g9z0h7e”, or the hackers will make a headache.

July 2003 Philippe Oechslin Lausanne Federal Institute of Technology announced a number of experimental results, and his own safety and Cryptography Laboratory (LASEC) replaced by the time the memory means, so greatly increased the efficiency of password cracking. As an example, they will be a common operating system password cracking rate from 1 minute 41 seconds, raised to 13.6 seconds. This method uses a large lookup table of the encrypted passwords and text input from the people to match, thus speeding the calculations required to decrypt. This is called “memory – time balance” method means that hackers can use a lot of memory to reduce the time required to crack the code.

Therefore, some hackers have been inspired to produce in advance that contains almost all possible passwords dictionary, and then convert the NTLM Hash all of its files, so that when the actual break, they do not need to carry out the conversion between the password and Hash , can be passed directly to the file of Hash hash to crack than Windows account password, saving a lot of system resources, Shidexiaolv can greatly enhance. Of course, this is just a simple statement of the method used is called in the international Time-Memory Trade-Off, or that the “memory – the time balance” method, some places will be translated into “time – the memory alternate algorithms. ”

The famous “memory – the time balance” Arithmetic

Specific aspects of this algorithm is no longer involved, who want to conduct more in-depth exploration of the reader, you can carefully the details of this 2003 document “Making a Faster Crytanalytical Time-Memory Trade-Off” and the 2005 document “Time -Memory Trade-Offs: False Alarm Detection Using Checkpoints “, later in this section will give the link.

It is because of the existence of Rainbow Tables, making ordinary computer in 5 minutes, long enough to crack the complex 14-bit Windows account password is possible.

Rainbow Tables to the Windows accounts crack

Similar c78j33c6hnws, yemawangluo178, 38911770 this Windows account password is almost all in 180 seconds or 3 minutes, breaking out, the shortest only 5 seconds longer password cracking open individual and no more than three minutes.

Tables for cracking WPA encryption principle

This uses a similar principle of Rainbow Tables, by Pre-Compute the pre-computation method, to carry out operations in advance in order to generate WPA-PSK encryption Hash, and thus set up WPA-PSK Hash Tables, can be as effective as a significant pre-conceived improve the efficiency of break. In general, you can be the previous 100 ~ ~ 300 key / s of ordinary single break rate, raised to 30,000 ~ ~ 100,000 key / s, raised nearly 300 to 1000 times!!! This is the external wireless hackers crack technology currently in use, on a number of underground organizations, and even individual uphold the dedication, and explore the nature of the hacker spirit by improving the optimization of code, etc. make the cracking rate broke through the 150,000 k / s, but also room to improve. The rate of what it means, if the home pulls it into the latest hardware? Smart you will understand.

In Cowpatty in to crack WPA Tables

I think, for many wireless users, this is the real nightmare. Ancient Greek philosopher Socrates once said that: “know thyself.”, But in fact often are rampant hacking sly, and many network and security management technology or on the attacker only Luezhipimao or to simply know nothing about, and do not even know what the so-called security configuration after the network architecture, will face what the actual risk.

Although the release of certain technologies may but will Yinqigebie spiteful man attention to wireless security, but for right concept of Pu Ji and Shen Ru understanding, helping many have or are being carried radio network planning of Jun police agencies, at businesses and Teshu departments, but also clearly recognize the risks of wireless networks, so as to improve its own deficiencies, to avoid unnecessary losses, the book is the starting point.

Of course, want to clarify is, Tables of the establishment and not so easy to imagine, on the establishment itself, its efficiency is very low, plus need to specify the pre-attack AP’s SSID, you want to establish a common access point for all, and a simple password WPA-PSK Hash Tables, their generated files hard disk space occupied by at least 1 ~ ~ 3G. Need to understand WPA Table of readers can go to, called The Church of Wifi wireless hackers know more, the organization’s official site for http://www.wifirobin.com/, the organization over the past two years successfully established a large WPA Table Library, and its simplified version of WPA-PSK Hash Table free download, for many wireless hackers, this is indeed a good news, but unfortunately, even a simplified version, its size also Yijing more than 30G.

Interested readers can go to http://www.wifirobin.com/ to download this simplified version of Table seed file, return to the Table all the download size 33.54GB, be noted that the formation of the Table is based on the dictionary, although Screening of hacker organization, but due to different national conditions, so which part of the contents may not be suitable for the use of the domestic situation. Although some people are using such names as passwords, in a foreign country may be similar to the Lilianjie this spelling, but to the domestic BruceLee it could be that the English name of the. Do not know it, crack the encryption method WPA wireless networks it is possible, but the basic is theoretical, but also a matter of cryptography experts.
