services / Azure / Storage Blob Service Blobs

Blobs are the individual data objects (files) stored inside containers of an Azure Storage account's blob service. They hold an organization's unstructured production data such as documents, backups, media, and application data.

Data-plane access to blobs directly exposes stored organizational data; ADLS Gen2 (hierarchical namespace) accounts also expose POSIX ownership/ACLs at the blob level.

Writing/overwriting blob content lets an attacker tamper with stored data and overwrite blobs with attacker-encrypted versions for ransomware extortion.

Risks

1. Data encryption (CRITICAL)
2. Data manipulation (HIGH)

Scope: HIGH

This privilege may grant access to sensitive data from a single organizational function, or allow interruption of a service supporting a single organizational function.
