A criminal online marketplace selling millions of sets of stolen personal information for as little as 56p per entry has been taken down in an international crackdown.
The sting, led by the FBI and Dutch police and involving law enforcement agencies across 17 countries, including the UK’s National Crime Agency (NCA), took Genesis Market offline on Tuesday evening.
Users trying to access the site are now greeted with a page emblazoned with the FBI investigation name Operation Cookie Monster.
The marketplace, one of the most significant of its kind in the world, had 80 million sets of credentials available for sale, affecting two million victims.
This enabled criminals to bypass online security checks by pretending to be the victim.
Investigators from the National Crime Agency carried out a series of raids on Tuesday and arrested 24 suspected users of the site.
Globally about 120 people were arrested and more than 200 searches carried out.
The NCA estimates there were hundreds of users of the site in the UK, and that tens of thousands of British victims have been targeted.
Will Lyne, head of cyber intelligence for the NCA, said: “Genesis Market is one of the top criminal access marketplaces anywhere in the world.
“Genesis Market is an enormous enabler of fraud and a range of other criminal activity online by facilitating that initial access to victims, which is a critical part of the business model in a whole range of nefarious activity.”
Prices started from 70 cents US (56p) and went up to several hundreds of dollars, depending on the type of information available.
Rob Jones, director-general of the National Economic Crime Centre, said it was “very, very easy” for anyone to access Genesis Market to commit crime.
“This is the problem for us in the online world – you don’t need to know a criminal to start,” he said.
“So you can completely self-start and go looking for this and get everything you need to perpetrate a crime.
“And so that is why this is so damaging. You don’t have to go and meet somebody, you don’t have to go into a shadowy forum; you can get into it, pay your money, and then you’ve got the tools to commit a crime.
“And that’s why it is so damaging, and it is very, very easy.”
NCA investigators have already set up spoof distributed denial-of-service sites, which bring down servers by flooding them with requests, to harvest the details of criminals, and may use similar tactics when it comes to fraud sites.
Mr Jones said: “Our approach to tackling the criminal marketplace is that cyber criminals won’t know who they’re interacting with and won’t know for certain that they are dealing with a criminal. And that could be a site that a partner or the NCA has access to and we’re getting their credentials.”
He added: “If you’re a cyber criminal, you’re not going to know whether we’ve got your credentials and whether you’re going to get a knock on the door in the morning.”
