GitHub Search Syntax for Finding API Keys/Secrets/Tokens

As a security professional, it is important to conduct a thorough reconnaissance. With the increasing use of APIs nowadays, it has become paramount to keep access tokens and other API-related secrets secure in order to prevent leaks. However, despite technological advances, human error remains a factor, and many developers still unknowingly hardcode their API secrets into source code and commit them to public repositories. GitHub, being a widely popular platform for public code repositories, may inadvertently host such leaked secrets. To help identify these vulnerabilities, I have created a comprehensive search list using powerful search syntax that enables the search of thousands of leaked keys and secrets in a single search.

Search Syntax:

(path:*.{File_extension1} OR path:*.{File_extension-N}) AND ({Keyname1} OR {Keyname-N}) AND (({Signature/pattern1} OR {Signature/pattern-N}) AND ({PlatformTag1} OR {PlatformTag-N}))

Examples:

**1.

openssl x509 -inform DER -in cacert.der -out cacert.pem
openssl x509 -inform PEM -subject_hash_old -in cacert.pem | head -1
mv cacert.pem <hash>.0  
adb push <hash>.0 /sdcard/Download/
adb shell
su
mkdir -m 700 /sdcard/cert/
cp /system/etc/security/cacerts/* /sdcard/cert/
mount -t tmpfs tmpfs /system/etc/security/cacerts

	// Revision 2 - improved by ChatGPT to be more efficient using Burp APIs!
	// Automatically updates the Cookie header in Burp Repeater requests using Set-Cookie values from responses. This Bambda CustomAction preserves all existing cookies and only updates or adds values when necessary — ensuring session continuity without overwriting unrelated cookies.

	// 1. Grab the request & response
	var request = requestResponse.request();
	var response = requestResponse.response();

	// 2. Pull any Set-Cookie cookies from the response
	var responseCookies = response.cookies();
