One of Aram Bartholl's USB dead drops installed in Brooklyn, NY
A USB dead drop is an anonymous, offline, peer-to-peer file sharing network in public space using a USB device.
Typically, a USB flash drive will be mounted in an outdoor brick wall and fixed in place with concrete. The name comes from the dead drop method of espionage communication.
The first USB dead drop network, of five devices, was started in October 2010 in New York by Berlin-based artist Aram Bartholl, a member of New York's Fat lab art and technology collective.
Everyone is invited to drop or find files on a dead drop by directly plugging their laptop into the USB stick in the wall to share files and data. Each dead drop is installed empty except a readme.txt file explaining the project.
Wireless dead drop 
Following this concept, wireless dead drops are being created.
Pros and cons 
Publicly and privately available points give anyone the ability to save and transfer data anonymously and free of charge. Such offline networks are vulnerable to the following examples of threats:
- Physical destruction: anyone can destroy a dead drop using pliers or a hammer, by high voltage from a static field, with high temperature from a blowtorch, or other methods of physical force.
- Software destruction: anyone can erase all of the data by deletion or drive formatting, or by encrypting the data or the whole drive and hiding the key.
- Espionage: anyone can intentionally or unintentionally infect it with malware such as trojan horse or keylogger.
- Disclosure: anyone can disclose the location of a private dead drop by shadowing people and publishing coordinates in a public place.
