How Dropgangs and Dead Drops Are Transforming Darknet Practices

Since the creation of the Silk Road, authorities have waged a war against the online drug trade with a wave of surveillance and enforcement. However, crypto-anarchists are developing new ways to evade the state’s tentacles as the next technological phase started to emerge in late 2017. On Monday, the Cypherpunk Bitstream podcast discussed the evolution of darknet markets as new ideas like dropgangs and dead drops proliferate into the next decade.

The Importance of Evolving Darknet Practices

At the end of 2019, the publication Vice highlighted the fact that since 2014 the number of users buying illicit narcotics on darknet markets (DNM) has doubled. Vice columnist David Hillier’s report underlines the fact that DNMs have increased since the Silk Road, but the growth of ‘Snapchat dealers’ and other instant messenger service drug operations has multiplied. For instance, Hillier cites a report called “DM For Details” which explains that in 2019, 24% of young people said “they see illicit drugs advertised for sale on social media.” 56% of the drugs being sold are on Snapchat, 55% of ads are seen on Instagram, and 47% leverage Facebook Messenger. The report detailed that cannabis is the most popular drug advertised 63% of the time, while cocaine was the second most popular drug.

Instant messenger services are now facilitating a new wave of online dealers. Vendors use these applications and utilize dead drop locations rather than using a DNM and the postal service.

Meanwhile, the podcast “Cypherpunk Bitstream” hosts Jonathan ‘Smuggler’ Logan and ‘Frank Braun’ published an episode which discussed the advancement of the online drug trade and Smuggler’s nine-page article “Dropgangs, or the Future of Darknet Markets.” Smuggler’s research studied how DNMs have evolved since they were first advertised on the clearnet and migrated to the deep web via the Silk Road (SR). When SR was seized by global law enforcement, dozens of new DNMs popped out of the woodwork with mega-markets like Dream and Alphabay.

However, in 2017, police forces shut down Alphabay and operated Hansa undercover for more than 30 days before closing it. Smuggler’s editorial notes that the “loss of darknet markets led to severe disruption of client-merchant relationships.”

“Identities and reputation being lost, previous marketing efforts being negated – often leading to temporary or even permanent collapse of merchant business,” he added. Despite the cat-and-mouse game of surveillance and evasion, Smuggler’s research notes:

The problems of darknet markets have triggered an evolution in online black markets.

Cypherpunk Bitstream Episode 0x04 Talks About Dropgangs, Dead Drops, Drone Mix networks, and Sneakernet

On January 6, 2020, Smuggler conversed about the topic of dropgangs on episode 0x04 of the podcast Cypherpunk Bitstream. Smuggler talked about the premise of his article with Frank Braun and defined what a dropgang is for listeners. “Dropgangs are organizations that distribute contraband by using mostly messenger services, often cryptocurrencies, and dead drops.”

Smuggler also gives an example of a dropgang that leverages messenger services like Telegram. Basically you text on Telegram, agree on a price, and the dealer sends coordinates to a secret location where you can pick up the goods. “[Darknet markets are] not the end of development when it comes to the distribution of contraband,” Smuggler emphasized on the podcast. “One of the tendencies of [DNMs] is that they appear, they’re used and then they go away. And in between, you have a lot of people that are arrested.”

Cypherpunk Bitstream episode 0x04 discusses the use of Sneakernets (or trainnets – pigeonets) as well.

Smuggler notes that in Eastern Europe and throughout the Balkan States, there’s another end of the spectrum of the online drug trade where DNMs have evolved. In a lot of Eastern European countries, the dominant model is different to a centralized DNM website that simply sells product. This is because vendors from these regions started using dead drops early, Smuggler told Braun during the podcast. Braun agreed and said that this was because the postal system in that area of the world was never really trustworthy. The dead drop method allows the vendor to drop the product at a secret and random geographical location that only the two parties are aware of. This idea skips the global mail systems and customers can remain anonymous and don’t have to reveal an address.

Postal Service Vulnerabilities

During the mid-section of the episode, Smuggler and Braun go into great detail on how the postal service flags and tracks suspected contraband dealers. Smuggler highlights the global mail systems’ flagging infrastructure and sorting equipment is digitally augmented. Some things are augmented so far that the letters get a tracing code printed on it and people don’t notice it, Smuggler says. If a package or letter is found suspicious, the hidden tracing code is added which flags all letters posted in the same container and allows investigators to track origins and create heat map-like data points. Smuggler insists that over time, the heat map tracking system is perfected and “you get a map with a statistical overlay.” The podcast host says this kind of mail inspection gives investigators a really good indication about where the sender is from and the frequency of mail the vendor ships.

Smuggler and Frank Braun discuss the intricacies tied to the postal services’ tracking systems. Dropgangs avoid the post altogether by leveraging dead drops.

The issues tethered to centralized DNMs and the postal service mail inspection process make Braun and Smuggler stress the importance of evolving black market practices. In addition to the discussion about dropgangs, dead drops, existing DNMs, and the postal service, the two hosts talk about the idea of drone mix networks that could leverage drones and hard-to-trace communication mixes.

Cypherpunk Bitstream’s episode 0x04 also touches upon concepts like sneakernet. Rather than transmitting information via connected computer networks, individuals leveraging the transfer of data via physical devices can greatly improve privacy. For instance, a person could create a BCH bearer bond instrument by using an optical disc, USB flash drive or external hard drive loaded with BCH and pass it along a network of individuals without the transactions ever being seen on a public block explorer. Sneakernet crypto trading might be essential after the Fifth Anti-Money Laundering Directive (5AMLD) and the updated FATF “Travel Rule” take effect this year. Four years ago, before bitcoiners became infatuated with institutional interest, a few decentralized marketplace ideas emerged.

On August 30, 2015, Reddit user miracle-max_ described a decentralized marketplace layer written on top of the BTC chain called the Drop Zone Protocol. The system was originally tested on BTC’s testnet and the author of the concept released a paper on the cryptography mailing list. The paper called “Drop Zone: An Anonymous Peer-To-Peer Local Contraband Marketplace” describes the system’s properties. It featured concepts like anonymous and encrypted communications with built-in reputation controls. Additionally, “contraband markets can be open and anonymous,” Miracle Max wrote at the time.

Another concept similar to Max’s Drop Zone is Voluntary Labs project Bitmarkets, an idea that leveraged Bitmessage for listings and buyer/seller communications and runs on Tor by default. Both Bitmarkets and Drop Zone never really materialized and people remained mostly dependent on centralized DNMs up until 2017. Since the fall of the major DNMs in 2017, the peer-to-peer application Openbazaar has been used lightly to facilitate contraband deals, mainly with narcotics like cannabis. Centralized DNMs have been a mess over the last two years and several of the most popular marketplaces went under in 2019.

Years ago, concepts like Bitmarkets and Drop Zone were all the rage with bitcoiners.

The recently published Cypherpunk Bitstream podcast is over three hours long, but gives a comprehensive overlook of where things are headed within the modernized online drug trade. Law enforcement seems to be leading the cat-and-mouse game but the podcast shows that evasion schemes are growing stronger in certain regions.
