Cybercrime: Limited impact of AlphaBay and Hansa’s demise

-

THElaw enforcem e n t operations that took down the AlphaBay and Hansa marketplac­es were meant to strike a sizeable blow to the online trade of illegal goods and services. Frequenter­s of these services might now think twice before placing their trust in these unregulate­d platforms, and there may well be further arrests to follow as investigat­ions and analysis into the materials seized in these raids run their course.

However, when a drug enforcemen­t operation completes a major bust or arrests a large number of individual­s, there is often always another group, or new recruits, ready to fill the void. Similarly, our analysis of the broader cybercrimi­nal ecosystem suggests that the impact of the AlphaBay and Hansa closures will be somewhat short-lived, for at least three reasons: 1. The game of whack-a-mole continues, cybercrime will find a way

With AlphaBay and Hansa out of the picture, sellers and users will flock to other marketplac­es to continue trading as before. This has been evident already, with former AlphaBay and Hansa users advertisin­g on establishe­d forums such as Dream Market, TradeRoute, House of Lions and Wall Street Market.

Marketplac­e takedowns are not a new phenomenon. When Silk Road, once the largest and most popular dark web marketplac­e, was disrupted by the Federal Bureau of Investigat­ion (FBI) in 2013, this only precipitat­ed the growth of other, alternativ­e platforms. AlphaBay grew from Silk Road’s closure and eventually took on the mantle of the most popular dark web market. Subsequent reincarnat­ions of Silk Road in the form of Silk Road 2.0 and Silk Road 3.0 exemplify how the cycle will likely continue for the foreseeabl­e future. We have seen alternativ­es emerge as a result of marketplac­e exit scams as well. In 2015, administra­tors from the Evolution Marketplac­e stole an estimated 40,000 BTC. Dream Market was once of the beneficiar­ies of that exit scam. Just as Jeff Goldblum’s Jurassic Park character, Doctor Ian Malcolm says, “Life uh, finds a way,” cybercrime finds a way as well. Commerce must flow; buyers and sellers need to be connected. 2. Alphabay, Hansa were only a part of a broader cybercrime ecosystem

Yes, AlphaBay and Hansa were two of the most popular English-language dark web marketplac­es. And yes, they had dedicated sections for fraudrelat­ed goods (stolen payment card informatio­n, counterfei­t documents, and compromise­d bank accounts), as well as malware and hacking tools (the RIG and Bleeding life exploit kits were previously advertised on AlphaBay). However, from an informatio­n security perspectiv­e, we should remember that most of the products advertised on these platforms were for drugs, weapons, and digital goods such as media accounts and service subscripti­ons.

Our research shows that there are other forums specifical­ly dedicated to hacking and security, which often act as a platform for trade. Sites like CrimeNet, HPC, and Exploit[.]in contain many examples of threat actors offering products such as ransomware variants, exploit kits, compromise­d accounts and payment card data. These sites work on a direct transfer system where vendors and customers will communicat­e directly to arrange payment, often through messaging services such as Jabber. Often sellers will advertise their products on these forums, and then direct users to dark websites to then arrange payment. Where stolen databases have appeared on sites like Hansa, we assessed it to be highly likely that these datasets were previously traded widely through other criminal networks and then listed on these marketplac­es only once their value had been exhausted.

Payment card fraud is a good example of why we should not focus too heavily on marketplac­es. There are countless carding and Automated Vending Cart (AVC) sites dedicated to payment card fraud. These types of sites often provide tutorials and courses for novice fraudsters, as we highlight in our recent whitepaper. With new carding and AVC sites emerging every day, this type of activity will continue unabated despite the AlphaBay and Hansa takedowns. 3. Not all cybercrime occurs on the

dark web Many carding, AVC and hacking sites are not actually found on the dark web, including HPC, CrimeNet and Exploit, which we mentioned above. Moreover, certain types of cybercrime do not need the “anonymity” provided by services such as Tor, or the advertisin­g and transactio­nal functions fulfilled by the marketplac­e model. Plenty of cybercrime occurs on the open and deep web.

Extortion activity by the darkoverlo­rd, a threat actor we have cited previously, illustrate­s this point. When the darkoverlo­rd first came to our attention in June 2016, the actor relied heavily on dark websites such as the Real Deal to advertise stolen datasets. Yet, since the closure of the Real Deal in November 2016, the darkoverlo­rd has remained active and has made use of clear websites such as Pastebin and Twitter to conduct extortion based activity. In June 2017, the darkoverlo­rd released eight episodes of an un-aired American Broadcast company (ABC) show, posting a message to Pastebin that included a link to the torrent website The Pirate Bay. Three days later, the darkoverlo­rd published over 6,000 medical records that allegedly belonged to a clinic in California. The documents were uploaded to the sharing site mega[.]nz after the clinic purportedl­y failed to respond to the ransom demands.

While the AlphaBay and Hansa takedowns will likely provide significan­t intelligen­ce gains, there will always be supply and demand for illicit goods and services. Digital Shadows will continue monitoring the developmen­t of the cybercrimi­nal ecosystem, particular­ly in these turbulent times. Marketplac­es were never seen as the go-to shop for rare exploits or sensitive datasets, and we expect the more sophistica­ted sellers to continue using more niche forums or private communicat­ion channels to flog their wares. Moreover, with other forms of cybercrime occurring outside of the dark web, organisati­ons and individual­s would be wrong to assume that the risk of a cyber-attack has now been significan­tly reduced.
