With Go's speed and efficiency, this tool really stands out when it comes to mass-testing. Always double check the results manually to rule out false positives. 10 | 11 | Subjack will also check for subdomains attached to domains that don't exist (NXDOMAIN) and are **available to be registered**. No need for dig ever again! This is still cross-compatible too. 12 | 13 | **What's New? (Last Updated 09/17/18)** 14 | - Custom fingerprint support 15 | - New Services (Re-added Zendesk && Added Readme, Bitly, and more) 16 | - Slight performance enhancements 17 | 18 | ## Installing 19 | 20 | Requires [Go](https://golang.org/dl/) 21 | 22 | `go get github.com/haccer/subjack` 23 | 24 | ## How To Use: 25 | 26 | Examples: 27 | - `./subjack -w subdomains.txt -t 100 -timeout 30 -o results.txt -ssl` 28 | 29 | Options: 30 | - `-d test.com` if you want to test a single domain. 31 | - `-w domains.txt` is your list of subdomains. 32 | - `-t` is the number of threads (Default: 10 threads). 33 | - `-timeout` is the seconds to wait before timeout connection (Default: 10 seconds). 34 | - `-o results.txt` where to save results to. For JSON: `-o results.json` 35 | - `-ssl` enforces HTTPS requests which may return a different set of results and increase accuracy. 36 | - `-a` skips CNAME check and sends requests to every URL. **(Recommended)** 37 | - `-m` flag the presence of a dead record, but valid CNAME entry. 38 | - `-v` verbose. Display more information per each request. 39 | - `-c` Path to configuration file. 40 | 41 | ## Practical Use 42 | 43 | You can use [scanio.sh](https://gist.github.com/haccer/3698ff6927fc00c8fe533fc977f850f8) which is kind of a PoC script to mass-locate vulnerable subdomains using results from Rapid7's Project Sonar. This script parses and greps through the dump for desired CNAME records and makes a large list of subdomains to check with subjack if they're vulnerable to Hostile Subdomain Takeover. Of course this isn't the only method to get a large amount of data to test. **Please use this responsibly ;)** 44 | 45 | ## Adding subjack to your workflow 46 | 47 | ```go 48 | package main 49 | 50 | import ( 51 | "fmt" 52 | "encoding/json" 53 | "io/ioutil" 54 | "strings" 55 | 56 | "github.com/haccer/subjack/subjack" 57 | ) 58 | 59 | 60 | func main() { 61 | var fingerprints []subjack.Fingerprints 62 | config, _ := ioutil.ReadFile("custom_fingerprints.json") 63 | json.Unmarshal(config, &fingerprints) 64 | 65 | subdomain := "dead.cody.su" 66 | /* Use subjack's advanced detection to identify 67 | if the subdomain is able to be taken over. */ 68 | service := subjack.Identify(subdomain, false, false, 10, fingerprints) 69 | 70 | if service != "" { 71 | service = strings.ToLower(service) 72 | fmt.Printf("%s is pointing to a vulnerable %s service.\n", subdomain, service) 73 | } 74 | } 75 | ``` 76 | 77 | See the [godoc](https://godoc.org/github.com/haccer/subjack/subjack) for more functions. 78 | 79 | ## FAQ 80 | **Q:** What should my wordlist look like? 81 | 82 | **A:** Your wordlist should include a list of subdomains you're checking and should look something like: 83 | ``` 84 | assets.cody.su 85 | assets.github.com 86 | b.cody.su 87 | big.example.com 88 | cdn.cody.su 89 | dev.cody.su 90 | dev2.twitter.com 91 | ``` 92 | 93 | ## References 94 | Extra information about Hostile Subdomain Takeovers: 95 | 96 | - [https://github.com/EdOverflow/can-i-take-over-xyz](https://github.com/EdOverflow/can-i-take-over-xyz) 97 | - [https://labs.detectify.com/2014/10/21/hostile-subdomain-takeover-using-herokugithubdesk-more/](https://labs.detectify.com/2014/10/21/hostile-subdomain-takeover-using-herokugithubdesk-more/) 98 | -------------------------------------------------------------------------------- /fingerprints.json: -------------------------------------------------------------------------------- 1 | [ 2 | { 3 | "service": "fastly", 4 | "cname": [ 5 | "fastly" 6 | ], 7 | "fingerprint": [ 8 | "Fastly error: unknown domain" 9 | ], 10 | "nxdomain": false 11 | }, 12 | { 13 | "service": "github", 14 | "cname": [ 15 | "github.io" 16 | ], 17 | "fingerprint": [ 18 | "There isn't a GitHub Pages site here." 19 | ], 20 | "nxdomain": false 21 | }, 22 | { 23 | "service": "heroku", 24 | "cname": [ 25 | "herokuapp" 26 | ], 27 | "fingerprint": [ 28 | "herokucdn.com/error-pages/no-such-app.html" 29 | ], 30 | "nxdomain": false 31 | }, 32 | { 33 | "service": "pantheon", 34 | "cname": [ 35 | "pantheonsite.io" 36 | ], 37 | "fingerprint": [ 38 | "The gods are wise, but do not know of the site which you seek." 39 | ], 40 | "nxdomain": false 41 | }, 42 | { 43 | "service": "tumblr", 44 | "cname": [ 45 | "domains.tumblr.com" 46 | ], 47 | "fingerprint": [ 48 | "Whatever you were looking for doesn't currently exist at this address." 49 | ], 50 | "nxdomain": false 51 | }, 52 | { 53 | "service": "wordpress", 54 | "cname": [ 55 | "wordpress.com" 56 | ], 57 | "fingerprint": [ 58 | "Do you want to register" 59 | ], 60 | "nxdomain": false 61 | }, 62 | { 63 | "service": "teamwork", 64 | "cname": [ 65 | "teamwork.com" 66 | ], 67 | "fingerprint": [ 68 | "Oops - We didn't find your site." 69 | ], 70 | "nxdomain": false 71 | }, 72 | { 73 | "service": "helpjuice", 74 | "cname": [ 75 | "helpjuice.com" 76 | ], 77 | "fingerprint": [ 78 | "We could not find what you're looking for." 79 | ], 80 | "nxdomain": false 81 | }, 82 | { 83 | "service": "helpscout", 84 | "cname": [ 85 | "helpscoutdocs.com" 86 | ], 87 | "fingerprint": [ 88 | "No settings were found for this company:" 89 | ], 90 | "nxdomain": false 91 | }, 92 | { 93 | "service": "s3 bucket", 94 | "cname": [ 95 | "amazonaws" 96 | ], 97 | "fingerprint": [ 98 | "The specified bucket does not exist" 99 | ], 100 | "nxdomain": false 101 | }, 102 | { 103 | "service": "ghost", 104 | "cname": [ 105 | "ghost.io" 106 | ], 107 | "fingerprint": [ 108 | "The thing you were looking for is no longer here, or never was" 109 | ], 110 | "nxdomain": false 111 | }, 112 | { 113 | "service": "shopify", 114 | "cname": [ 115 | "myshopify.com" 116 | ], 117 | "fingerprint": [ 118 | "Sorry, this shop is currently unavailable." 119 | ], 120 | "nxdomain": false 121 | }, 122 | { 123 | "service": "uservoice", 124 | "cname": [ 125 | "uservoice.com" 126 | ], 127 | "fingerprint": [ 128 | "This UserVoice subdomain is currently available!" 129 | ], 130 | "nxdomain": false 131 | }, 132 | { 133 | "service": "surge", 134 | "cname": [ 135 | "surge.sh" 136 | ], 137 | "fingerprint": [ 138 | "project not found" 139 | ], 140 | "nxdomain": false 141 | }, 142 | { 143 | "service": "bitbucket", 144 | "cname": [ 145 | "bitbucket.io" 146 | ], 147 | "fingerprint": [ 148 | "Repository not found" 149 | ], 150 | "nxdomain": false 151 | }, 152 | { 153 | "service": "intercom", 154 | "cname": [ 155 | "custom.intercom.help" 156 | ], 157 | "fingerprint": [ 158 | "This page is reserved for artistic dogs.", 159 | "
