11 JavaScript Global Variables

These are the non-standard "global" variables defined on the window object. These can be helpful in identifying possible client-side frameworks and code.

0 Cookies

Cookies are little pieces of information stored in the browser of a user. Whenever a user visits the site again, he will also send his cookie values, thus allowing the website to re-identify him even if he changed locations. This is how permanent logins work.

2 Console Messages

A page may trigger messages to the console to be logged. These are often error messages about being unable to load a resource or execute a piece of JavaScript. Sometimes they also provide insight into the technology behind a website.

Source	Level	URL Text
console-api	info	URL: https://jam.systems/bundle.js(Line 20596) Message: %cDownload the React DevTools for a better development experience: https://reactjs.org/link/react-devtools font-weight:bold
console-api	error	URL: https://jam.systems/bundle.js(Line 16447) Message: The above error occurred in the <App> component: at App (https://jam.systems/bundle.js:26030:17) Consider adding an error boundary to your tree to customize error handling behavior. Visit https://reactjs.org/link/error-boundaries to learn more about error boundaries.

Indicators

This is a term in the security industry to describe indicators such as IPs, Domains, Hashes, etc. This does not imply that any of these indicate malicious activity.
