1 bug, $50,000+ in bounties, how Zendesk intentionally left a backdoor in hundreds of Fortune 500 companies

hi, i'm daniel. i'm a 15-year-old with some programming experience and i do a little bug hunting in my free time. here's the insane story of how I found a single bug that affected over half of all Fortune 500 companies:

say hello to zendesk

If you've spent some time online, you’ve probably come across Zendesk.

Zendesk is a customer service tool used by some of the world’s top companies. It’s easy to set up: you link it to your company’s support email (like [email protected]), and Zendesk starts managing incoming emails and creating tickets. You can handle these tickets yourself or have a support team do it for you. Zendesk is a billion-dollar company, trusted by big names like Cloudflare.

Personally, I’ve always found it surprising that these massive companies, worth billions, rely on third-party tools like Zendesk instead of building their own in-house ticketing systems.

Sample PowerShell script that shows you how to create a .BMP file of the display of a Hyper-V virtual machine.
$VMName = "VM 1"
$BMPName = "C:\Users\benja\Desktop\test.bmp"
Add-Type -AssemblyName "System.Drawing"
$VMCS = Get-WmiObject -Namespace root\virtualization\v2 -Class Msvm_ComputerSystem -Filter "ElementName='$($VMName)'"
# Get the resolution of the screen at the moment
$video = $VMCS.GetRelated("Msvm_VideoHead")
$xResolution = $video.CurrentHorizontalResolution[0]
