I’m new to testing for dependency confusion and need some advice. I made a public NPM package named like an internal tool I saw in some JS code. I put a DNS ping in the index.js file.
After uploading it, I got a DNS ping from an AWS IP. But there was no HTTP callback or payload running.
Can someone help me understand:
- Does a DNS ping from a cloud IP mean for sure that a system tried to install my package?
- Is this maybe just how the NPM registry works?
- How certain should I be before I tell anyone about this?
I want to learn the right way to do this and not assume too much. Any tips would be great. Thanks!
hey mate, dns pings from aws ips can be tricky. npm uses cloud stuff so it might just be their system checkin ur package. to be sure, u need more solid proof like callbacks or logs showin ur package actually runnin somewhere. dont jump the gun reportin stuff without bein 100% sure. stay safe out there!
A DNS ping from an AWS IP isn’t conclusive evidence of dependency confusion. NPM’s infrastructure uses cloud services, so this could be part of their standard package processing.
To confirm an actual installation, you’d need more substantial proof like execution logs or callbacks with system details. Without that, it’s premature to report anything.
For future tests, consider implementing more sophisticated telemetry in your package. This could include unique identifiers or specific data collection points that would clearly indicate if your package was installed and run on a target system.
Always ensure you have proper authorization before conducting such tests. Dependency confusion can have serious implications, so it’s crucial to approach it with caution and thorough understanding.
As someone who’s dealt with dependency confusion testing before, I can share some insights. A DNS ping from an AWS IP alone isn’t definitive proof of a successful attack. NPM and other package registries often use cloud infrastructure, so this could be part of their normal operations.
To be more certain, you’d want to see evidence of your package actually being installed and executed on a target system. This might include HTTP callbacks with system information or logs showing your package in use.
It’s crucial to approach this carefully. False positives can lead to unnecessary alarm, and you don’t want to cry wolf. I’d recommend setting up more detailed telemetry in your package and possibly using a dedicated testing environment to simulate the target infrastructure.
Remember, responsible disclosure is key if you do find a genuine vulnerability. Always get proper authorization before testing on systems you don’t own or control. It’s a complex area, so tread carefully and keep learning!
