Public S3 Bucket Exposes 273k Indian Bank Transfers

🔓 UpGuard discovered a publicly accessible Amazon S3 bucket containing over 273,000 PDFs documenting individual bank transfers in India, many with unredacted account numbers, amounts, and personal contact details. Aye Finance was disproportionately represented in the sample, and researchers observed roughly 3,000 new files added daily before the bucket was secured following notifications to AyeFin, NPCI, and CERT‑IN. The exposure poses an immediate risk of large‑scale fraud and targeted abuse across dozens of banks.

Mass Exposure of Indian Bank NACH Transfer PDFs Repository

🔓 UpGuard discovered a publicly accessible Amazon S3 bucket containing roughly 273,160 PDF documents formatted as NACH MANDATE records that documented bank transfers in India. The files exposed unredacted bank account numbers, transaction amounts and, in many cases, individuals’ names, phone numbers and email addresses. A 55K-file sample (~42 GB) showed 38 financial institutions represented, with AyeFin appearing in nearly 60% of sampled records. UpGuard notified AyeFin and NPCI, escalated to CERT‑IN when the bucket continued to grow, and verified the repository was secured on September 4.

Source-of-Truth Authorization for RAG Knowledge Bases

🔒 This post presents an architecture to enforce strong, source-of-truth authorization for Retrieval-Augmented Generation (RAG) knowledge bases using Amazon S3 Access Grants with Amazon Bedrock. It explains why vector DB metadata filtering is insufficient—permission changes can be delayed and complex identity memberships are hard to represent—and recommends validating permissions at the data source before returning chunks to an LLM. The blog includes a practical Python walkthrough for exchanging identity tokens, retrieving caller grant scopes, filtering returned chunks, and logging withheld items to reduce the risk of sensitive data leaking into LLM prompts.

AWS Network Firewall Enhances Console Monitoring and TLS

🔒 AWS Network Firewall now delivers expanded console monitoring and enhanced TLS inspection capabilities to improve outbound security. The monitoring dashboard adds visibility into traffic to AWS services such as Amazon S3, Amazon DynamoDB, and AWS Backup, including traffic sent over PrivateLink, and surfaces top source and destination IPs by packets and bytes. Customers can filter views by IP and protocol for targeted analysis. A new session holding feature for TLS Inspection prevents TCP/TLS establishment from reaching servers until SNI-based rules are evaluated, strengthening controls against malicious endpoints.

Amazon S3 Adds Conditional Deletes for General Buckets

🔒 Amazon S3 now supports conditional deletes in S3 general purpose buckets. You can include an HTTP If-Match header with an object's ETag when calling DeleteObject or DeleteObjects; S3 will only delete the object if the provided ETag matches, reducing accidental removals in high-concurrency, multi-writer environments. Administrators can also enforce conditional deletes using the s3:if-match bucket policy condition. The capability is available at no additional cost in all AWS Regions and accessible via the API, SDKs, and CLI.

Amazon S3 Batch Operations: Manage Objects by Bucket

📦 Amazon S3 Batch Operations now allows users to target all objects within an S3 bucket, or refine selection by prefix, suffix, creation date, or storage class directly from the AWS Management Console. Instead of providing a manifest, customers can specify these filters when creating a job and S3 will apply the chosen operation to every matching object and produce a detailed completion report. Typical use cases include copying between buckets, restoring archived data from Glacier classes, and computing checksums for datasets. The capability is available in all AWS Regions and can also be accessed via the AWS CLI or SDK.
