Cloud Storage Misconfigurations: A Practical Guide to S3, Azure Blob, and GCP

June 2, 2026 · khukuririmal · Red Teaming

Object storage is where most of the internet’s data quietly lives like backups, user uploads, build artifacts, static website assets, logs, database dumps. It’s also where a huge share of real-world data breaches begin. Not through some exotic zero-day, but through a checkbox someone toggled wrong, a policy that was copy-pasted from different sources of […]

CDN Security Assessment Checklist for Pentesters: A Practical Guide to Assessing CDN-Protected Applications

May 31, 2026 · khukuririmal · Pentesting Fundamentals

Content Delivery Networks (CDNs) have become a standard component of modern web applications. Whether it is a small startup application or a large enterprise platform, chances are that traffic is passing through a CDN before reaching the origin server. From a business perspective, CDNs improve performance, reduce latency, and help absorb large volumes of traffic. […]

Load Testing and Controlled DoS Assessment During Red Team Assessments

May 29, 2026 · khukuririmal · Red Teaming

Red Team engagements extend beyond identification of traditional exploitation paths such as authentication bypasses, injection flaws, exposed assets, or privilege escalation. Organizations increasingly depend on application resilience, API stability, and infrastructure availability as critical security pillars. While offensive security teams traditionally focus on confidentiality and integrity impacts, availability testing when performed safely and with authorization […]

Cloud Bucket Enumeration in VAPT & Red Teaming

May 24, 2026 · khukuririmal · Red Teaming

Cloud storage has become a critical component of modern applications. Organizations frequently rely on cloud object storage services to host static assets, backups, application artifacts, logs, mobile application resources, and even sensitive operational data. Common cloud storage services include: Misconfigured cloud storage continues to contribute to data exposure incidents because bucket names are often predictable, […]

Wireless (Wi-Fi) Penetration Testing: A Practical Checklist for Real-World Assessments

April 3, 2026 · khukuririmal · VAPT

Wireless networks often form the weakest link in an organization’s security posture. Unlike wired infrastructure, Wi-Fi signals extend beyond physical boundaries, making them inherently exposed to unauthorized access attempts. A misconfigured wireless network can allow attackers to bypass perimeter defenses, gain internal network access, and pivot toward critical systems such as Active Directory, internal applications, […]

Practical Guide To Getting Your First CVE

March 1, 2026 · khukuririmal · Pentesting Fundamentals

Getting a CVE ID (Common Vulnerabilities and Exposures) assigned to your name is a significant milestone in cybersecurity. It reflects meaningful contribution to the security ecosystem.However, let’s set expectations clearly:Finding a vulnerability in well-maintained, reputed software, tools and repo’s is somewhat difficult. It often requires deep research, time, reverse engineering, and persistence. This guide is […]
