One of Aram Bartholl's USB dead drops

A USB dead drop is a USB mass storage device installed in a public space. For example, a USB flash drive might be mounted in an outdoor brick wall and fixed in place with fast concrete.[1] Members of the public are implicitly invited to find files, or leave files, on a dead drop by directly plugging their laptop into the wall-mounted USB stick in order to transfer data. (It is also possible to use smartphones and tablets for this purpose, by utilizing a USB on-the-go cable.) The dead drops can therefore be regarded as an anonymous, offline, peer-to-peer file sharing network. However, in practice USB dead drops are often used for social or artistic reasons, rather than for practical ones.

Background and history

The Dead Drops project was conceived by Berlin-based conceptual artist Aram Bartholl, a member of New York's F.A.T. Lab art and technology collective. The first USB dead drop network of five devices was started by Bartholl in October 2010 in Brooklyn, New York City.[2] The name comes from the dead drop method of espionage communication. An unrelated system called "deadSwap," in which participants use an SMS gateway to coordinate passing USB memory sticks on to one another, was begun in Germany in 2009.[3]

Each dead drop is typically installed without any data on the drive, except two files:[4] deaddrops-manifesto.txt,[5] and a readme.txt file explaining the project.[6] Although typically found in urban areas embedded in concrete or brick since 2010, installation of USB dead drop into trees[7] and other types of bodies in natural settings has also been mentioned since at least 2013.[4][8] Wireless dead drops such as the 2011 PirateBox, where the user connects to a Wi-Fi hotspot with local storage rather than physically connects to a USB device, have also been created.[9][10][11]

Comparison to other types of data transfer

Some of the advantages of utilizing USB dead drops are practical in nature: they permit P2P file sharing without needing any internet or cellular connection, sharing files with another person secretly/anonymously, and they record no IP address or similar personally identifying information. Other benefits are more social or artistic in nature: USB dead drops are an opportunity to practice "datalove" and can be seen as a way to promote off-grid data networks. The motive to utilize USB dead drops has been compared to what drives people involved in geocaching, which has been around for much longer and is somewhat similar in that often a set of GPS coordinates is used to locate a particular USB dead drop,[12] in particular that USB dead drops give the user "the thrill of discovery"[13] both in seeking out the location of the dead drop, and then also in addition when examining the data it contains. A QR-Code dead drop including the data in the QR Code image or pointing to a decentral storage is an alternative and less risky option to a physical USB dead drop as long as people cover their IP address.

Potential drawbacks to users

Dead drops are USB-based devices, which must be connected to an upstream computer system (laptop or smartphone or similar). The act of making such a connection, to a device which is not necessarily trusted, inherently poses certain threats:

Drawbacks to the system infrastructure

Publicly and privately available USB dead drops give anyone (with physical access) the ability to save and transfer data anonymously and free of charge. These features are advantages over the internet and the cellular network, which are at best quasi-anonymous and low-cost (there is always some fee associated although in certain scenarios such as government-subsidized or employer-subsidized or public-library-subsidized network access the end user may experience no direct costs). However, offline networks are vulnerable to various types of threats and disadvantages, relative to online ones:

Prevalence

As of 2013, there were more than one thousand known USB dead drops (plus six known wifi-based dead drops).[7] Countries which have large numbers of USB dead drops include the United States and several in Europe.[7] As of 2016, it was estimated that the overall dead drop infrastructure contained more than ten terabytes of storage capacity, with the majority still in the United States and Europe, but also with significant numbers of devices reportedly installed in the Asia/Pacific region, South America, and Africa.[16][13]
