Cloud Squatting: Guarding Abandoned Digital Territories

The cloud computing revolution has brought with it a myriad of advancements and efficiencies. However, it also introduces a new realm of cybersecurity threats, one of which is cloud squatting. This phenomenon, where attackers exploit abandoned or deleted cloud assets, poses significant risks to organizations. Through this blog, we'll explore the mechanics of cloud squatting, its potential impact, and strategies to counteract these threats.

Cloud Squatting: Guarding Abandoned Digital Territories

Understanding Cloud Squatting

Cloud squatting occurs when cybercriminals take advantage of cloud-based resources that organizations have discarded or stopped using. These could include domain names, storage accounts, or identifiers for virtual machines. When these resources are left unsecured or not properly decommissioned, they become easy targets for malicious actors.

A Cloud Security Alliance report from 2021 showcased instances where companies faced phishing attacks originating from their own, previously abandoned cloud domains.

The Mechanics Behind Cloud Squatting

  1. Lifecycle of Cloud Resources: Organizations often create, use, and then discard cloud resources as needs evolve. However, the process of decommissioning these resources is sometimes overlooked, leaving them accessible online.

  2. Malicious Actors' Strategy: Cybercriminals are always on the lookout for such overlooked resources. They register these abandoned names and use them for nefarious purposes.

  3. Modes of Attack: These resources, once commandeered, can be used for launching phishing attacks, spreading malware, or even for masquerading as legitimate entities to conduct fraud.

Why Cloud Squatting is a Serious Concern

  1. Data Breaches and Leakage:

  • Access to Sensitive Information: In cases where cloud storage containing sensitive data is abandoned without proper security measures, squatting can lead to data breaches.

  • Gateway to Further Attacks: These compromised cloud assets can serve as a launching pad for more severe attacks against the company’s current IT infrastructure, leading to potential data breaches and loss.

  1. Reputational Damage:

  • Misuse of Brand Identity: If a cloud resource associated with a particular brand or company is squatted, it can be used to mislead customers or tarnish the brand’s reputation.

  • Brand Impersonation: For instance, squatting on an old business domain could lead to phishing schemes under the guise of a legitimate brand.

  1. Legal and Compliance Issues:

  • Regulatory Non-Compliance: Squatted resources might inadvertently put a company at risk of non-compliance with privacy and data protection laws.

Palo Alto Networks' 2022 research highlighted the alarming fact that a sizable portion of cloud resources in many organizations are not properly deactivated, thereby increasing the risk of cloud squatting.

Proactive Measures Against Cloud Squatting

Comprehensive Asset Management

  • Inventory of Cloud Assets: Maintain a current and comprehensive inventory of all cloud assets and regularly review their usage. Periodic reviews of cloud assets should be a standard protocol. This helps in identifying and securely decommissioning unused resources, thereby reducing the risk of squatting.

  • Proper Decommissioning Procedures: Develop and enforce strict policies for decommissioning cloud resources. This includes not just the deletion but also the secure wiping and inaccessibility of these resources.

Regular Security Audits and Monitoring

  • Scheduled Audits: Conduct regular security audits to identify and address vulnerabilities in cloud setups.

  • Continuous Monitoring: Use cloud security tools for ongoing monitoring of cloud services to detect unauthorized access or activity.

Employee Education and Access Control

  • Training Programs: Staff training is key. Those handling cloud resources should be well-aware of the risks associated with improperly decommissioned assets.

  • Access Revocation: Ensure prompt revocation of cloud access for employees who leave the organization.

Secure Data Deletion and Transfer Protocols

  • Data Wiping: Ensure that data is not just deleted but securely wiped from cloud storage when no longer needed.

  • Data Transfer: Securely transfer data from obsolete accounts to active ones, ensuring no residue is left behind.

  • Control of Subdomains: Manage subdomains and URLs effectively. Unused domains should either be redirected securely or completely removed from the web.

Collaboration with Cloud Providers

  • Provider Support: Work closely with cloud service providers to understand and implement best practices for securing cloud resources.

Preparing for a Secure Cloud Future

As we delve deeper into the era of cloud computing, being aware of and prepared for threats like cloud squatting is imperative. Organizations must adopt a vigilant and proactive approach, incorporating rigorous decommissioning processes, continuous monitoring, and a culture of security awareness. It's not just about protecting digital assets; it's about safeguarding the organization's integrity and trust in the digital ecosystem.
