How to use `<details>` `<summary>` expandable content on GitHub with Markdown

Firstly, what is <details> <summary>?

The HTML Details Element (<details>) creates a disclosure widget in which information is visible only when the widget is toggled into an "open" state. A summary or label can be provided using the <summary> element. https://developer.mozilla.org/en-US/docs/Web/HTML/Element/details.

Example

Backup android app, data included, no root needed, with adb

Note: This gist may be outdated, thanks to all contributors in comments.

You must enable developer mode (tap 7 times on the build version in parameters) and install adb on your PC.

Don't hesitate to read comments, there is useful tips, thanks guys for this !

Log4J CVE Advisory

The Problem

Log4J has a feature called Java Naming and Directory Interface (shortened to JNDI in this document), which allows a Java program to reach out to an external source to gather data.
If you put a section of text containing ${jndi:query} into the log, the Log4J library will try to resolve the query.
This can be combined with the Lightweight Directory Access Protocol (LDAP) to connect to a remote server.

However, because JNDI is built for retrieving data, and JNDI is a Java program, if you put a JNDI query using LDAP into a log, it will connect to the given site, download a file, and then execute it.
This is called Remote Code Execution.
