Warshipping Definition
Warshipping (sometimes written as “war shipping”) is a cyberattack method in which an attacker sends a concealed device to a target location to access its wireless network from close range. Unlike attacks that require the cybercriminal to stay near the building, warshipping allows the attacker to operate remotely, away from the delivered device. This technique is often used in scenarios such as corporate espionage, unauthorized network access, or testing security weaknesses in physical and wireless environments.
How Warshipping Works
The attack starts with a single-board computer, a wireless adapter, and a power source hidden inside a package or other delivered item. Once the package reaches the target location, the device is activated and connects back to the attacker using a mobile data connection or another remote link. Because it is physically inside or near the target environment, it can access wireless networks that would normally be out of reach.
From there, the device scans for nearby Wi-Fi networks, attempts to connect to them, or creates a fake access point to trick users into connecting. It can also capture network traffic or collect login credentials. If the attacker gains access to the network or obtains valid credentials, they can use that foothold to move deeper into internal systems and carry out further attacks.
Warshipping vs Wardriving vs Evil Twin Attacks
Warshipping is often compared with wardriving and evil twin attacks, but they use different methods. Wardriving involves searching for vulnerable Wi-Fi networks from a nearby car or another location, so the attacker has to stay close to the target. Evil twin attacks use a fake Wi-Fi network that looks real to trick people into connecting and giving up data or login details. Warshipping relies on a device placed at the target location and then operated remotely.
How to Prevent Warshipping
- Check unexpected packages before they're brought further inside the building.
- Keep deliveries away from secure rooms, network equipment, and desks until they've been inspected.
- Secure Wi-Fi with encryption, strong passwords, and separate guest access.
- Watch for unknown access points, unfamiliar devices, and unusual wireless activity.
- Require multi-factor authentication to make stolen login details less useful.
- Train staff to question suspicious deliveries and fake Wi-Fi prompts.
- Use wireless intrusion detection/prevention (WIDS/WIPS) to monitor for rogue access points, unusual wireless activity, or unauthorized devices connecting to the network.

FAQ
Warshipping can be hard to detect because the device may arrive as part of an ordinary delivery and not look suspicious at first. It may also go unnoticed if staff treat the package as routine or leave it near active equipment.
One of the clearest signs is unusual wireless activity. That may include a new Wi-Fi signal, repeated connection problems, or login prompts that seem out of place. Security teams may also spot unfamiliar hardware on the network or traffic patterns that don't match normal use.
Warshipping can target home networks, but it's usually discussed as a business threat. Offices, shared buildings, and other workplaces often receive more deliveries and manage more wireless connections, which can make the attack easier to carry out. Home networks are still possible targets, especially if an attacker has a clear reason to single out one location.
Strong Wi-Fi security can make warshipping harder, but it's not enough on its own. Attackers may still look for weak devices, poor package handling, or user mistakes. Better protection usually comes from combining wireless security with delivery checks, network monitoring, and staff awareness.
Yes. Network segmentation helps contain the damage by separating sensitive systems from the rest of the network. If one area is exposed, it can reduce how far an attacker is able to move. It works best as part of a broader security setup.
