'It is also renowned for advertising major breaches containing millions of records while many dark web shops keep a low profile and attempt to stay discrete, Joker's Stash enjoys its notoriety and boasts about media coverage.

'In the past 12 months, it has posted over 35 million CP records and over 8 million CNP records,' Thomas told ZDNet. The Joker's Stash portal has been operating since October 7, 2014, and often posts packs of stolen payment card details that can be used for both CP (card present) and CNP (card not present) fraudulent transactions. The actor does not appear to be concerned with law enforcement's actions,' Christopher Thomas, Intelligence Production Analyst at Gemini Advisory, told ZDNetВ in an email yesterday. 'Notably, JokerStash was one of the original proponents of moving dark web services to Blockchain technology. bazar domain likely will not do much to disrupt Joker's Stash, especially since the team behind Joker's Stash maintain several versions of the site and the site's Tor-based links are still working normally,' the Digital Shadows team said. In blog posts this week, both Intel 471В and Digital ShadowsВ described the FBI & Interpol disruption attempt as 'temporary.' The Joker's Stash operator said the domains would be restored on new servers 'in a few days.'

In a message posted on an underground forum brought to ZDNet's attention by Irina Nesterovsky, Chief Research Officer at threat intel firm KELA, one of the Joker Stash administrators confirmed the disruptions but said that law enforcement only seized the servers hosting the four domains, which only acted as proxies, redirecting users to the actual Joker's Stash portal. Records for these domains are stored inside a blockchain and cannot be transferred to anyone else without the domain owner's cryptographic signature. These are websites that use top-level domains (TLDs) managed by Emercoin, a blockchain company. Seizure banners appeared on four Joker's Stash sites, at jstash.bazar, jstash.lib, jstash.emc, and in. In an email this week, Interpol described the server seizures as an ongoing 'coordinated police operational activity' but declined to elaborate further.

Officials from the US Federal Bureau of Investigation and Interpol have seized a small number of servers used by Joker's Stash, the internet's largest marketplace for buying & selling stolen cards, temporarily disrupting the site's activity.
