Jscythe - Abuse The Node.Js Inspector Mechanism In Order To Force Any Node.Js/Electron/V8 Based Process To Execute Arbitrary Javascript Code

jscythe abuses the node.js inspector mechanism in order to force any node.js/electron/v8 based process to execute arbitrary javascript code, even if their debugging capabilities are disabled.

Tested and working against Visual Studio Code, Discord, any Node.js application and more!

How

1. Locate the target process.
2. Send SIGUSR1 signal to the process, this will enable the debugger on a port (depending on the software, sometimes it's random, sometimes it's not).
3. Determine debugging port by diffing open ports before and after sending SIGUSR1. …
