10 Non-Obvious S3 Integration Vulnerabilities Exposed in Web Application Bug Bounty Research

Security researcher Sergey Bobrov, known as BlackFan, published a detailed analysis of S3 misconfigurations when integrated into web applications via proxies such as nginx. The article examines ten laboratory setups demonstrating issues ranging from stored XSS and bucket takeover to rewrite rule bypasses and cache poisoning. Key findings highlight how nginx path normalization differences, missing trailing slashes, and variable usage like $uri enable attackers to reach arbitrary buckets or inject HTTP request splitting payloads. The research covers both direct S3 client usage and proxy-based integrations, emphasizing ACL and Bucket Policy errors that expose data to any authenticated S3 user worldwide. Practical demonstrations include exploitation of Ceph RGW path traversal with ../ sequences and cache key collisions via response-content-type parameters. The work provides fingerprinting tables for identifying S3-compatible systems including MinIO, Ceph RGW, and Yandex Cloud based on headers and error responses.

IT Elements 2026 to Stage IT Apocalypse Simulations and Critique Russian Vendors

The IT Elements 2026 conference has unveiled its full program, centering on business continuity after successful cyberattacks, infrastructure failures, or technological disasters. Scheduled for September 9-10 at the Serp i Molot cultural center in Moscow, the event will host over one hundred reports, discussions, demonstrations, and master classes. The opening plenary will examine whether the primary-backup data center model remains viable, if the 3-2-1 backup rule still protects against modern ransomware, and whether CIOs or CISOs should own cyber resilience. Practical sessions will demonstrate a full Microsoft migration in 60 minutes, moving Exchange and MinIO to Russian alternatives, and a detailed review of domestic hyperconvergence strengths and weaknesses. Comparative test results for routers, NGFW, and VM systems will be presented without marketing gloss. Additional tracks will cover monitoring of corporate AI models from GPU to prompt under FSTEC Order No. 117, OWASP Top 10 for LLM, and MITRE ATLAS, alongside real-world cases from Rosatom, Beeline, Sber, and T-Bank. Trubnaya Metallurgicheskaya Kompaniya will simulate a 48-hour IT outage and show how to restart operations in half a day.

Building Secure MLOps Platforms in Air-Gapped Environments for DevOps Engineers

The article explains how DevOps engineers can construct a minimal yet complete MLOps platform inside a closed, air-gapped network without relying on any cloud services. It highlights the cultural gap between data scientists and DevOps teams and shows how MLOps practices such as data versioning, experiment tracking, and model registries bridge that gap. The architecture separates GPU training nodes from a Kubernetes serving cluster and uses open-source components including ArgoCD for GitOps, MLflow with PostgreSQL, MinIO, DVC, OpenBao, and External Secrets Operator. Special attention is given to secrets management with SOPS and age keys, image scanning with Trivy and Bandit, and secure Docker access via socket proxy on the training server. The setup avoids Kubeflow and HashiCorp Vault due to complexity and licensing concerns, favoring lighter, license-friendly alternatives suitable for isolated perimeters.
