Original: Anatomy of a Pentest Dropbox: How Remote Internal Assessments Actually Work
Short summary
A pentest dropbox is a small computer planted inside a target's network to enable remote internal assessments without on-site presence. It makes outbound connections to the tester's server, bypassing inbound firewall restrictions, and runs scanning and enumeration locally for speed. For defenders, the key takeaways are network segmentation, egress filtering, and monitoring for anomalous outbound traffic.
- •Pentest dropboxes are small computers placed inside target networks for remote internal assessments
- •They call out to the tester's server, exploiting permissive outbound firewall rules
- •Defenders should focus on network segmentation and egress monitoring to detect such footholds
