Dead Drops: Anonymous, Offline, Peer-to-Peer File-Sharing Network in Public Space

dead drops

‘Dead Drops’ is an anonymous, offline, peer to peer file-sharing network in public space. USB flash drives are embedded into walls, buildings and curbs accessable to anybody in public space. Everyone is invited to drop or find files on a dead drop. Plug your laptop to a wall, house or pole to share your favorite files and data. Each dead drop is installed empty except a readme.txt file explaining the project. ‘Dead Drops’ is open to participation. If you want to install a dead drop in your city/neighborhood follow the ‘how to’ instructions and submit the location and pictures.

If only there was some way to keep these from filling up with malware, porn and spam.

Learning about cryptography, fidonet and the postal system won’t do anyone any harm. Nothing beats trusted person-to-person connections established in many only-partially overlapping social / professional circles.

A Bitcoin-based E-Bay for Illegal Drugs

drugs A Bitcoin based E Bay for Illegal Drugs

Gawker is running an unbelievable story on website called Silk Road – an open market for mail ordering illegal drugs. And it’s only accessible through TOR:

Mark, a software developer, had ordered the 100 micrograms of acid through a listing on the online marketplace Silk Road. He found a seller with lots of good feedback who seemed to know what they were talking about, added the acid to his digital shopping cart and hit “check out.” He entered his address and paid the seller 50 Bitcoins—untraceable digital currency—worth around $150. Four days later the drugs, sent from Canada, arrived at his house.

“It kind of felt like I was in the future,” Mark said.

Buyer beware: TOR is not untraceable. And an update from Bitcoin’s development team indicates that Bitcoin isn’t 100% anonymous either.

From a comment on Facebook:

The only thing that Jeff Garzik, the Bitcoin developer, forgot to mention are the extremely useful Bitcoin Laundries. They allow you to obscure and obfuscate the origin of a Bitcoin, allowing you to effectively ‘launder’ the Bitcoin so that network analysis would be futile. And they are free, simple, and widely available. They probably “forgot” that because it would make it seem even EASIER than it already is to buy drugs online.

I would still urge caution in using this service.

How Osama bin Laden Used E-Mail Without An Internet Connection

  • Posted on May 13, 2011 at 10:09 am

According to the Associated Press’ sources, Osama bin Laden routinely typed e-mails on an Internet-less computer in his compound, saved them to a USB thumbdrive and had a courier e-mail them from cybercafes in nearby towns. Apparently this went on for years, undetected. According to the AP, Navy SEALS found about 100 flash drives that apparently contain series of these e-mail communications.

This is what’s referred to as a sneakernet, and as Internet crackdowns occur all over the world, it may become an increasingly popular way for people to communication.
