The digital shadows stretch long across the network, but sometimes, the most insidious threats don't crawl through fiber optic cables – they arrive via the humble postal service. A term coined in 2019, "WarShipping," describes the chilling potential of wireless attacks delivered stealthily through the mail. It’s a concept that sounds like fiction, a digital ghost in the shell arriving in a cardboard box. But how likely is a Warshipping attack to cripple a major enterprise? Is it just a theoretical boogeyman, or a tangible risk lurking in the supply chain?
This episode delves into the murky waters of physical infiltration, sponsored by Varonis.

Our team, seasoned operators in the clandestine arts of ethical hacking, decided to put this theory to the test. We engineered a low-cost Warshipping payload, a digital Trojan Horse assembled with chilling efficiency. The mission: to ship tracking packages to three major businesses, observing firsthand if Warshipping is more than just a buzzword – if it’s a genuinely viable attack vector in today's interconnected world.
The findings were, to put it mildly, unsettling. Not only was the attack astonishingly cheap, costing a mere $10 to execute, but it proved to be frighteningly effective. This wasn't a theoretical exercise; it was a blueprint for a breach, delivered right to the company's doorstep, or rather, their mailroom.

What is WarShipping?
WarShipping fundamentally exploits the trust placed in physical delivery systems. In 2019, the term emerged to encapsulate the concept of embedding malicious wireless devices within packages. These devices, often small and discreet, lie dormant until activated or triggered, potentially by proximity to a target network or specific signals. Unlike remote attacks that are often met with firewalls and intrusion detection systems, WarShipping bypasses traditional network defenses entirely, presenting a physical threat that pivots into the digital realm. It’s a testament to the attacker's mindset: if the network is a fortress, find the secret tunnel. In this case, that tunnel is the loading dock.
$10 Attack Payload
The true audacity of some cyber threats lies in their simplicity and cost-effectiveness. Our exploration into WarShipping confirmed this adage. With a budget of just $10, a functional attack payload can be assembled. This typically involves a small, self-contained device capable of wireless communication – think along the lines of unassuming USB drives or small, non-descript electronic components. These devices are often pre-configured to emit a signal, establish a rogue access point, or even initiate a phishing attempt once they reach their destination. The low barrier to entry means that even actors with limited resources can pose a significant threat, making the threat landscape far more unpredictable.
Company Mail Room Experiment
The core of our clandestine operation involved shipping tracking packages to three unsuspecting major businesses. The objective was to mimic a legitimate delivery and observe the journey of the package from the mailroom into the heart of the organization. Our team, operating with the precision of seasoned intelligence operatives, meticulously documented each step. The mailroom, often a neglected nexus of physical and digital entry points, became our primary target. From the moment the package was received, we tracked its handling, looking for opportunities to exploit. This phase is critical; it’s where the physical trust of the organization is inadvertently weaponized against it.

Phishing & Rogue Access Point Demo
Once the package was within the target environment, the next phase of the attack commenced. We demonstrated two potent methods of digital infiltration: phishing and the deployment of a rogue access point. The payload could be configured to broadcast a Wi-Fi signal mimicking a legitimate network, luring unsuspecting employees to connect, thereby granting access. Simultaneously, or in conjunction, a phishing campaign could be initiated. This could range from a simple email sent from a compromised internal system to a sophisticated web interface presented to the user, all designed to extract credentials or deploy further malware. The convergence of physical delivery and digital bait creates a potent one-two punch.
Credentials & Reconnaissance
The prize in any cyber engagement is often credentials. With a successful phishing attempt or a compromised access point, attackers can harvest employee login details. This is where the real deep dive begins. Armed with valid credentials, the attacker transitions from a ghost at the gate to an insider. Automated tools and manual reconnaissance scripts are deployed to map the internal network, identify critical assets, discover vulnerabilities in internal systems, and locate sensitive data. The initial $10 investment blossoms into an extensive intelligence gathering operation, painting a detailed picture of the target's digital infrastructure, ready for exploitation.
Implications & Ways to Secure Yourself
The implications of a successful WarShipping attack are profound. It bypasses layers of network security, exploits human trust, and can lead to full network compromise, data exfiltration, and significant financial and reputational damage. This isn't just about a few stolen passwords; it's about a potential breach of critical infrastructure. So, how do you defend against this insidious threat?
Defensive Measures:
- Mailroom Security Protocols: Implement strict protocols for handling incoming mail and packages. Designate a specific, controlled area for all deliveries.
- Package Inspection: Train staff to be vigilant for suspicious packages – unusual weight, odd markings, or unsolicited items. Consider a mandatory holding period for all incoming packages before they reach employees.
- Network Segmentation: Ensure your internal network is segmented. If a device from a package gains access, it should be isolated and unable to pivot to critical systems.
- Wireless Network Monitoring: Deploy robust wireless intrusion detection systems (WIDS) to detect unauthorized access points. Regularly audit your Wi-Fi environment for rogue devices.
- Employee Training: Conduct regular security awareness training, specifically highlighting the risks of WarShipping and advising employees on how to handle suspicious mail and report potential threats.
- Physical Security: Control physical access to mailrooms and sensitive areas.
- Asset Management: Maintain an accurate inventory of all hardware and devices connected to your network. Unidentified devices appearing on the network should trigger immediate investigation.
The $10 Warshipping payload is a stark reminder that in the realm of cybersecurity, the digital and physical worlds are inextricably linked. Neglecting physical security can have catastrophic digital consequences.

Frequently Asked Questions
- Q: Is WarShipping a real threat for small businesses?
A: While large corporations are primary targets due to potential data value, small businesses can also be vulnerable, especially if they handle sensitive data or are part of a larger supply chain. The low cost makes it accessible. - Q: How quickly can a WarShipping device be activated?
A: Activation methods vary. Some devices are pre-programmed to activate upon receiving power (e.g., from a USB port), while others might be triggered by proximity to a specific wireless signal or by a remote command. - Q: What is the primary goal of a WarShipping attack?
A: The primary goal is typically to gain an initial foothold into the target's network, enabling further reconnaissance, credential harvesting, and ultimately, deeper network compromise.
