Reveal Hidden Files in Google Storage - Pwnedlabs (Cloud pentesting)

Identifying and Cracking Exposed Cloud Storage Backups In this challenge, we begin by inspecting the web page elements to uncover an internal Google Cloud Storage URL: https://storage.googleapis.com/it-storage-bucket . 1. Initial Enumeration Attempting to list the bucket contents directly via the gcloud CLI or browser often results in a "Permission Denied" (403) error if listing is disabled, even if individual files are publicly accessible. To bypass this, we perform directory fuzzing to find specific hidden files. Using the ffuf tool and a targeted backup wordlist, we can identify valid paths. Command: ffuf -u https://storage.googleapis.com/it-storage-bucket/FUZZ -w /usr/share/wordlists/backup_files_only.txt -mc 200 The fuzzer successfully identifies a match: backup.7z . 2. Data Exfiltration Once the file path is confirmed, we exfiltrate the archive to our local machine using the gcloud storage utility. Command: gcloud storage cp gs://it-storage-bucket/backup.7z . 3.
