破解故事——我是如何破解1億2200萬SHA1和Md5哈希密碼

破解故事——我是如何破解1億2200萬SHA1和Md5哈希密碼

原文：http://blog.thireus.com/cracking-story-how-i-cracked-over-122-million-sha1-and-md5-hashed-passwords/

這是關於我如何破解密碼的哈希值1億2200萬* John the Ripper和oclHashcat-plus故事。

這是幾個月前，當我看到一條推特（https://twitter.com/m3g9tr0n）從korelogic約含共1億4600萬個密碼的密碼哈希表的torrent文件（https://www.korelogic.com/InfoSecSouthwest2012_Ripe_Hashes.html）。這個非常大的數量的密碼哈希起初讓我很沮喪，因爲我自己只有一臺經典配置的AMD Phenom II 4核3.2 MHz的電腦,外加一個ATI/AMD 5770顯卡。但我真的很想給嘗試一下，因爲該領域的密碼破解讓我着迷。

在這漫長的旅程中我用的密碼破解工具是John the Ripper和oclHashcat-puls。這篇文章是關於破解korelogic提供的MD5哈希值，但同樣的策略也適用於SHA1哈希破解。

更新：

08/29/2012 –新的例子在John the Ripper部分: "在dict2hash.pl腳本的幫助下破解雙MD5密碼值"

08/29/2012 – 所有的都進行過排序和整理新的版本下載。

處理哈希值：

首先，所有的korelogic torrent文件必須被解壓縮，它包含一個命名爲“校驗”文件夾。讓我們檢查這個文件夾的內容…

root@m3g9tr0n:~/hashes$ ls

longer_salts  raw-md5.hashes.txt  salted_with_md5  SHA1 vBulletin-v3.8.4

從現在起我們集中在raw-md5.hashes.txt文件列表，這個文件是4.3GB，通過wc工具可以看出它包括139444502行。

root@m3g9tr0n:~/hashes$ wc -lraw-md5.hashes.txt

139444502 raw-md5.hashes.txt

正如你可以假設，無論是John the Ripper和oclHashcat-plus都無法加載該文件，因爲它太大了。出於這個原因，我們需要分割該文件。在Linux下，我們有一個很好的工具稱爲split 做這件工作得很好：

root@m3g9tr0n:~$ split --help

Usage: split [OPTION]... [INPUT[PREFIX]]

Output fixed-size pieces of INPUT toPREFIXaa, PREFIXab, ...; default

size is 1000 lines, and default PREFIXis `x'.  With no INPUT, or when INPUT

is -, read standard input.

Mandatory arguments to long options aremandatory for short options too.

 -a, --suffix-length=N   usesuffixes of length N (default 2)

 -b, --bytes=SIZE        put SIZEbytes per output file

 -C, --line-bytes=SIZE   put atmost SIZE bytes of lines per output file

 -d, --numeric-suffixes  usenumeric suffixes instead of alphabetic

 -l, --lines=NUMBER      put NUMBERlines per output file

     --verbose           print adiagnostic just before each

                            output file isopened

     --help     display this help andexit

     --version  output versioninformation and exit

SIZE may be (or may be an integeroptionally followed by) one of following:

KB 1000, K 1024, MB 1000*1000, M1024*1024, and so on for G, T, P, E, Z, Y.

We can use the --lines=NUMBER parameter tosplit our raw-md5.hashes.txt file.

我們可以使用“--lines=NUMBER”參數來分割我們的原始md5.hashes.txt文件。

root@m3g9tr0n:~/hashes$ split -l 3000000raw-md5.hashes.txt part

請注意，考慮到每個MD5哈希是32字節長，我們還可以基於MB來進行文件分割。

使用oclHashcat-plus來破解密碼

我開始玩oclHashcat-plus，因爲它包含了-remove選項，一旦被破解它從hashfile刪除破解成功的哈希值，這是真的很方便。oclHashcat-plus唯一的限制，是它對密碼長度的限制。換句話說，它僅能夠破解密碼最多15個字符。我使用oclHashcat-plus規則是base64.rule，passwordspro.rule，T0XlC.rule在某些情況下d3ad0ne.rule。這些規則可以直接從oclHashcat-plus中找到。

暴力破解技術是不是我的第一選擇。我用的字典是從g0tm1lk的BlogSpot下載的（http://blog.g0tmi1k.com/2011/06/dictionaries-wordlists/?redirect）。在g0tmi1k的文章其他外部鏈接中你會發現更多的字典。破解過程中最大的一部分是通過使用這些字典與上述規則進行。讓我們來看看一些例子

使用單一規則：

./oclHashcat-plus64.bin -m 0 ~/hashes/md5_1~/Wordlists/d3ad0ne.dic -r rules/best64.rule -o Ultimate_Crack/eNtr0pY_1--remove

使用組合規則：

./oclHashcat-plus64.bin -m 0 ~/hashes/md5_1~/Wordlists/d3ad0ne.dic -r rules/best64.rule r rules/passwordspro.rule -oUltimate_Crack/eNtr0pY_1 --remove

Bruteforce attack with mask (you canspecify whichever charset you want):

使用掩碼進行暴力破解***（可以指定任何你想要的字符集）：

./oclHashcat-plus64.bin -a 3 -1 ?l?d?u?s -m0 ~/hashes/md5_1 ?1?1?1?1?1?1?1?1 -o Ultimate_Crack/eNtr0pY_1 --remove

組合破解：

 

./oclHashcat-plus64.bin -a 1 -m 0~/hashes/md5_1 ~/Wordlists/d3ad0ne.dic ~/Wordlists/list -oUltimate_Crack/eNtr0pY_1 --remove

使用規則進行組合破解：

./oclHashcat-plus64.bin -a 1 -m 0~/hashes/md5_1 ~/Wordlists/d3ad0ne.dic ~/Wordlists/list -r rules/passwordspro.rule-o Ultimate_Crack/eNtr0pY_1 --remove

排列組合破解：

./oclHashcat-plus64.bin -a 4 -m 0~/hashes/md5_1 ~/Wordlists/d3ad0ne.dic -o Ultimate_Crack/eNtr0pY_1 --remove

排列組合規則破解：

./oclHashcat-plus64.bin -a 4 -m 0~/hashes/md5_1 ~/Wordlists/d3ad0ne.dic -r rules/best64.rule -oUltimate_Crack/eNtr0pY_1 --remove

In some cases, I used the hybrid + maskattack technique:

在某些情況下，我使用了混合 + 掩碼***技術：

./oclHashcat-plus64.bin -a 6 -1 ?l?d -m 0 ~/hashes/md5_1~/Wordlists/d3ad0ne.dic ?1?1 -o Ultimate_Crack/eNtr0pY_1 --remove

混合掩碼規則破解：

./oclHashcat-plus64.bin -a 6 -1 ?l?d -m 0~/hashes/md5_1 ~/Wordlists/d3ad0ne.dic ?1?1 -r rules/best64.rule -oUltimate_Crack/eNtr0pY_1 --remove

在這一點上，我沒有用最後兩個方法，因爲他們是非常耗時的。我寧願爲John the Ripper 找到一個更好的KoreLogic的規則，將John the Ripper 的輸出管道到oclHashcat-plus。正如我所說，oclHashcat-plus能夠破解的密碼最多15個字符。出於這個原因，我不得不通過“--stdout”選項限定每一次所產生的單詞長度。如果你擁有一個非常快速的GPU可以跳過下面的例子。

./john --wordlist=~/Wordlists/all.lst-rules:KoreLogicRulesPrependYears --stdout=10 | ./oclHashcat-plus64.bin -m 0~/hashes/md5_1 -o Ultimate_Crack/eNtr0pY_1 --remove

當然你也可以使用來自Korelogic創建的其他前置的規則，像KoreLogicRulesPrependNumNum，甚至更好的創建自己的規則！是時候從破解密碼的單詞表中生成字典來破解剩餘哈希值了。從eNtr0pY_1，使用以下命令我刪除了MD5哈希值。

cut -b34- eNtr0pY_1 >eNtr0pY_1.dic

通過使用上述製造的字典，大量MD5哈希值被這種指紋***破解。你可以閱讀更多關於馬丁博斯@purehate這種***，我向你保證，這個技術是非常成功的！

當然，你也可以使用hashcat-utils中的二進制文件以及每一個管道到oclHashcat-plus的輸出。

root@m3g9tr0n:~/oclHashcat-plus-0.08/hashcat-utils$ls

combinator.bin  expander.bin gate.bin  len.bin  mp32.bin permute.bin  prepare.bin  req.bin splitlen.bin

使用John the Ripper破解密碼

測試完所有我收集的字典以及幾天後，是時候轉移到john the Ripper來破解密碼哈希值的剩餘部分...

我用的Magnum-ripper編譯OpenCL支持ATI / AMD顯卡，因爲我想用“--format=raw-md5-opencl參數”。相比“--format=raw-md5”，這是更快的方式爲它使用你的CPU和GPU。

與john the Ripper中使用的規則是：

wordlist

Single

NT

Extra

KoreLogicRulesAppendNumbersandSpecials_Simple

KoreLogicRulesAppend6Num

KoreLogicRulesPrependAndAppendSpecial

KoreLogicRulesAppendNumNum_AddSpecialEverywhere

KoreLogicRulesAppendNumNumNum_AddSpecialEverywhere

KoreLogicRulesL33t.

您可以下載這些規則，並將其添加到您的john.conf文件中：

http://paste2.org/p/2048517

http://paste2.org/p/2048512

現在，讓我們看到john the Ripper的一些例子...

使用--rules=Single：

./john --format=raw-md5-opencl--wordlist=../../Wordlists/all.lst --rules:Single ~/hashes/md5_1

哈希破解結果存儲在默認文件john.pot中。您可以使用cat，more，head和tail檢查它的內容。

root@m3g9tr0n:~/Tools/Password_Cracking/magnum-jumbo-OpenCL/run$tail -n 9 john.pot

$MD5$0fad81e7a61b47d387dde893fcf8e88a:anacarolinagu

$MD5$0f3c99478362aae389d2cbf716394269:stthomasmoresu

To generate a wordlist from the john.pot file,you can use the following command.

要從john.pot文件生成從一個字典，可以使用下面的命令。

cut -d: -f 2- john.pot | sort -u >cracked.dic

生成的字典可以與上述規則相結合來破解哈希值。

當我使用oclHashcat-plus破解MD5哈希值時，我觀察到，一些生成的密碼被拒絕。這是因爲oclHashcat-plus有一個關於字符串長度的限制。出於這個原因，我管道hashcat的結果輸出到john the Ripper，並且在john the Ripper中更好的使用hashcat規則。

./hashcat-cli64.bin --stdout~/Wordlists/d3ad0ne.dic -r rules/best64.rule | ./john --format=raw-md5-opencl--stdin ~/hashes/md5_1

嘗試所有字典與上述規則相結合後，是時候使用john the Ripper進行暴力破解破解。不幸的是，john the Ripper暴力破解***時不使用掩碼***以產生密碼。我們有基於包含在破解的密碼來創建我們自己的字符集john.pot。

./john --make-charset=eNtr0pY.chr

Loaded 7948325 plaintexts

Generating charsets... 1 2 3 4 5 6 78 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 DONE

Generating cracking order... DONE

Successfully written charset file:eNtr0pY.chr (95 characters)

你們中許多人會想知道“DONE 31”......這僅僅是因爲我編譯john the Ripper用31個字符長度。默認情況下，john the Ripper被編譯爲8個字符長度的支持，所以最好通過修改頭文件params.h中的以下行來改變，它位於john the Ripper的scr文件夾中。

#define CHARSET_MIN                     ' '

#define CHARSET_MAX                     0x7E

#define CHARSET_SIZE                    (CHARSET_MAX - CHARSET_MIN+ 1)

#define CHARSET_LENGTH                  8 //更改爲31或者你期待的值

最後，在john.conf中你必須包括您所創建的字符集，以如本例中規定：

# Incremental modes

[Incremental:eNtr0pY]

File = $JOHN/eNtr0pY.chr

MinLen = 0

MaxLen = 31

CharCount = 95

Now it is time to use bruteforce attackswith our own charstet!

現在是時候用我們自己的字符串來進行暴力破解***！

./john --format=raw-md5-opencl--incremental=eNtr0pY ~/hashes/md5_1

如果你查看john.conf，你會看到一些暴力破解***模式分爲外部。這些都是雙重的，帶鍵盤（使用從鍵盤字符產生的相鄰組合），KnownForce，日期時間，重複，順序，亞羣和DumbForce爲瘋狂的密碼格式。

./john --format=raw-md5-opencl--external=DumbForce ~/hashes/md5_1

在這裏提供的dict2hash.pl腳本幫助下，我們也喜歡破解雙重MD5哈希值。

perl dict2hash.pl < rockyou.txt | ./john--format=raw-md5-opencl --stdin ~/md5_1

在這裏，您可以看到與john the Ripper破獲MD5值的一些示例：

http://pastebin.com/uaGFXkBA

http://pastebin.com/LT5Gda9L

Personally, I believe a password like"$MD5$0b26a0faf1344d6e772bf55628e10e29:n34=mn { .clipboard $me }" isimpossible to crack with bruteforce attacks.

Note: All the abovementioned techniques canbe used with oclHashcat-plus by defining -m 100 and with John the Ripper bydefining --format=raw-sha1-opencl for SHA1 cracking with OpenCL!

就個人而言，我相信密碼像“ $ MD5 $ 0b26a0faf1344d6e772bf55628e10e29：N34 = {MN $.clipboard$me} ”是不可能使用暴力破解***來破解。

注：所有上述技術可以在oclHashcat-plus定義參數“-m 100”使用，john the Ripper定義“--format=raw-sha1-opencl”使用OpenCL破解SHA1

結論

這是一個非常耗費時間和艱苦的工作，因爲我不擁有最快的顯卡。整個破解過程歷時約5個月來完成，因爲我必須完成我的CCNP認證學習。

 

 

 

 

從中學到的教訓是，一個好的智能詞典結合方便的規則，使用Hashcat或John the Ripper甚至可以破解強密碼。基於以上情況，管理員應該使用更強的哈希算法（加鹽）來存儲你的密碼，並在在定期的基礎上更改自己的密碼。

你可以下載破解的哈希結果值

 721.9 MB -m3g9tr0n_122Million_Passwords_WordLists.zip

所提供的KoreLogic torrent文件包含了各種獨特的密碼哈希值。出於這個原因，你可能會在這些字典中發現重複的密碼，作爲一個單獨的密碼，可以使用各種算法來計算散列值！這意味着1.22億獨特的哈希值（MD5，SHA1，雙MD5等）被破解，結果中有8億3600萬個獨特的密碼。

 

您也可以下載“都在一個”版本，乾淨和分類：
