( CNN ) -- Authorities say Silk Road , the shadowy `` deep Web '' site shut down by the FBI this week , was the Internet 's biggest destination for drugs and other illegal goods . It had nearly 1 million registered users , the bureau says , and was used for roughly $ 1.3 billion in transactions over the past two or so years . But shuttering Silk Road and arresting its owner wo n't be the end of the shadowy black market on the Web , where drugs are far from the only products that can be bought illegally . The so-called `` deep Web '' consists of sites only accessible using tools like Tor , which includes a browser designed to hide the user 's identity by routing their activity through a series of remote connections . Many sites use intentionally cryptic web addresses -- Silk Road 's last was `` silkroadfb5piz3r.onion '' -- that spread stealthily via word of mouth . Here is a look at just some of the illegal goods that have been documented as offered for sale on these underground sites . ( We 're not linking to them , sorry . ) Drugs . Maybe it should be no big surprise , but hours after Silk Road was shut down , Web users were flocking to online forums with one question : `` Where can I buy my drugs now ? '' The answer ? Take your pick . Sites with names like Sheep Marketplace , Black Market Reloaded and Deep Bay were just some of the ones being mentioned as possibilities . Another , called Atlantis , had emerged earlier this year as a Silk Road competitor with an aggressive social-media campaign . In June , someone claiming to be the site 's owner even conducted an AMA ( `` Ask Me Anything '' ) session on Reddit . `` We want to bring attention to the site and bring our vendors more buyers , '' that person said during the session . `` Law enforcement is going to be aware of us ( and probably already is ) regardless of the way we choose to put our product out there . '' Two weeks ago , Atlantis announced it was shutting down due to `` security reasons outside of our control . '' Weapons . Illegal guns can be found on similar sites , as can legal weapons by people who may not pass a background check or otherwise be allowed to buy them . Last year , Gizmodo reporter Sam Biddle spent some time on The Armory , an offshoot of Silk Road devoted to weaponry . As part of his reporting , he posed as someone arming a paramilitary group bent on `` taking on a 3rd world government organization . '' The helpful responses poured in . `` I can provide : tec9 , scorpion , ak47 and one single vietnam war 'thumper ' , but its ammo costs , '' read one , the final reference being to a grenade launcher . `` Absolutely , we can accommodate your request , but we need more parameters such as your exact arms needs and destination country , '' read another . `` We only deal with small arms and equipment , but if you need artillery , MANPADS ( Man-portable air-defense systems ) , ordinance , APCs , Helos we do have resources and can make certain introductions for a fee . '' About a month after the Gizmodo piece ran , Silk Road 's owner announced it was shutting down The Armory , citing high prices and lack of interest . Exotic animals . The International Fund for Animal Welfare calls the illegal sale of wild animals online `` one of the major wildlife conservation challenges of our generation . '' `` The rise of the Internet has revolutionized the way we exchange ideas , information and merchandise . ... '' reads a report from the group . `` However , as a result , the Internet is also facilitating the illegal trade in wildlife , which is having a devastating effect on animals , ecosystems and the communities that rely on them worldwide . '' The report , in which the group tracked activity on 183 websites , documented the sale of elephant ivory , birds of prey , tigers , large snakes and other rare or endangered creatures . The relative anonymity the Web provides , combined with a patchwork of laws from state to state and country to country , make policing animal trafficking a tough job , the group said . Fake documents . Along with drugs , firearms and solicitations of hackers , Silk Road also had forged documents for sale , the FBI said . In July , the FBI says it intercepted nine false IDs bound for Ross William Ulbricht , who they say is `` Dread Pirate Roberts , '' the man behind the site . `` Roberts '' had been soliciting fake identification documents on Silk Road to use in buying more server space for the site . It should n't have been hard . A simple Google search for fake passports renders websites like FalsePassports.cc and IdentificationConsulting.com . Need a `` novelty '' driver 's license ? Several sites offer those , and you can get a diploma and Social Security card while you 're at it . `` For your own personal use and amusement , '' notes Global Intelligence ID Cards Solutions . Obviously .
Drugs are n't the only illegal items for sale online . Black market sites use `` deep Web '' tools like Tor to hide . Guns , endangered animals , fake IDs all for sale . Silk Road was shut down this week by the FBI .
