Finder Of XSS, and Dal is the Korean pronunciation of moon.
DalFox is a fast, powerful parameter analysis and XSS scanner, based on a golang/DOM parser. supports friendly Pipeline, CI/CD and testing of different types of XSS. I talk about naming. Dal(달) is the Korean pronunciation of moon and fox was made into Fox(Find Of XSS).

Class | Key Feature | Description |
---|---|---|
Discovery | Parameter analysis | – Find reflected param – Find alive/bad special chars, event handler and attack code – Identification of injection points(HTML/JS/Attribute) inHTML-none inJS-none inJS-double inJS-single inJS-backtick inATTR-none inATTR-double inATTR-single |
Static analysis | – Check bad-header like CSP, XFO, etc.. with req/res base | |
BAV analysis | – Testing BAV(Basic Another Vulnerability) , e.g sqli ssti open-redirects | |
Parameter Mining | – Find new param with Dictonary attack (default is GF-Patterns) – Support custom dictonary file ( --mining-dict-word )– FInd new param with DOM | |
Built-in Grepping | – It Identify the basic info leak of SSTi, Credential, SQL Error, and so on | |
Scanning | XSS Scanning | – Reflected xss / stored xss – DOM base verifying – Blind XSS testing with param, header( -b , --blind options)– Only testing selected parameters ( -p , --param )– Only testing parameter analysis ( --only-discovery ) |
Friendly Pipeline | – Single url mode (dalfox url )– From file mode ( dalfox file urls.txt )– From IO(pipeline) mode ( dalfox pipe )– From raw http request file mode ( dalfox file raw.txt --rawdata ) | |
Optimizaion query of payloads | – Check the injection point through abstraction and generated the fit payload. – Eliminate unnecessary payloads based on badchar | |
Encoder | – All test payloads(build-in, your custom/blind) are tested in parallel with the encoder. – To Double URL Encoder – To HTML Hex Encoder | |
Sequence | – Auto-check the special page for stored xss (--trigger )– Support ( --sequence ) options for Stored XSS , only sxss mode | |
HTTP | HTTP Options | – Overwrite HTTP Method (-X , --method )– Follow redirects ( --follow-redirects )– Add header ( -H , --header )– Add cookie ( -C , --cookie )– Add User-Agent ( --user-agent )– Set timeout ( --timeout )– Set Delay ( --delay )– Set Proxy ( --proxy )– Set ignore return codes ( --ignore-return ) |
Concurrency | Worker | – Set worker’s number(-w , --worker ) |
N * hosts | – Use multicast mode (--multicast ) , only file / pipe mode | |
Output | Output | – Only the PoC code and useful information is write as Stdout – Save output ( -o , --output ) |
Format | – JSON / Plain (--format ) | |
Printing | – Silence mode (--silence )– You may choose not to print the color ( --no-color )– You may choose not to print the spinner ( --no-spinner ) | |
Extensibility | REST API | – API Server and Swagger (dalfox server ) |
Found Action | – Lets you specify the actions to take when detected. – Notify, for example ( --found-action ) | |
Custom Grepping | – Can grep with custom regular expressions on response – If duplicate detection, it performs deduplication ( --grep ) | |
Custom Payloads | – Use custom payloads list file (--custom-payload ) | |
Package | Package manager | – homebrew with tap – snapcraft |
Docker ENV | – docker hub – gitub package of docker |
And the various options required for the testing 😀

Format
- Type:
G
(Grep) ,R
(Reflected) ,V
(Verify) - Informatin: Method, grepping name, etc..
Why is there a gap? It is a method to make it easier to parse only the poc code through cut etc. For example, you can do this.
$ dalfox url http://testphp.vulnweb.com/listproducts.php\?cat\=123\&artist\=123\&asdf\=ff | cut -d " " -f 2 > output
$ cat output
