The Digital Chess Game: Navigating DNS Security in the Cloud Era

Exploring DNS security challenges through personal experiences with and a suspicious incident on’s subdomain


The suspicious DNS record ( we stumbled upon has been taken down. This move indicates that Nestle has taken note of the issue, possibly acknowledging the misuse of their domain for unintended purposes.

While this is a positive step towards resolving the issue, we’re still in the dark about the specifics. Nestle hasn’t yet responded to our inquiries, leaving us curious about the backstory of this incident. Was it an oversight, a security lapse, or something more complex?


In the intricate world of digital security, DNS management plays a crucial role, often resembling a complex chess game. Recently, I encountered an issue with my domain,, and stumbled upon a similar situation with, highlighting the importance of vigilance in the era of cloud servers.

My Personal Encounter with DNS Exploitation

A while ago, Google Search Console notified me about a new owner of a subdomain under This subdomain, once active on a Digital Ocean platform, was linked to a droplet (a virtual server) that had long been deactivated. The dormant IP, now in the hands of a new user, was still associated with my subdomain. Cleverly exploiting this, an unknown actor used my subdomain for distributing Bollywood movies.

The realization hit when the actor attempted to add the domain to the search console, triggering a notification from Google. This incident underscores the importance of regularly pruning unused DNS A records, particularly those linked to public IP addresses in cloud environments like Digital Ocean.

The Incident: A Parallel Story

My discovery of a similar situation with added another dimension to this issue. Researching a job listing board, I noticed a dubious job post for Amazon, hosted on a Nestle subdomain (, removed the link after realizing it’s possiblity pushing malware). The listing led to multiple redirects, eventually landing on a form on, which seemed unrelated to either Amazon or Nestle.

This situation at Nestle, involving a subdomain pointing to a Microsoft Azure IP address, raises questions: Was it a case of a dormant FQDN being hijacked, or perhaps a rogue employee using Nestle’s resources for personal gain? Nestle has been notified, and we await their response.

Lessons and Strategies for DNS Management

These incidents highlight the critical need for vigilance in DNS management, especially in cloud server environments. Regularly monitoring DNS query logs and being alert to spikes in requests can preempt unauthorized usage of dormant subdomains. In my case with, quick action upon receiving Google’s notification helped mitigate potential damage.

Concluding Thoughts

As we navigate the ever-evolving digital landscape, the importance of proactive and informed DNS management cannot be overstated. The incidents with and serve as reminders of the ongoing challenges in maintaining digital security and the need for constant vigilance in the cloud era.
