Wannacry money laundering attempt thwarted

The hackers behind the Wannacry ransomware have tried to conceal who they are by using a virtual currency that is more anonymous than Bitcoin.
Victims paid more than $140,000 (£107,000) in bitcoins to recover files scrambled by Wannacry.
Earlier this week the gang behind the attack started to move the bitcoins out of the wallets they were paid into.
But the operators of the exchange they used to swap the bitcoins have now frozen the accounts they used.
Cash call
Wannacry caught out thousands of firms around the world when it infected computers on corporate networks and encrypted their files, making them useless.
Victims were told to pay between $300 (£229) and $600 (£458) in bitcoins to have their files unscrambled and return computers to a working state.
Many security experts believed the money paid into three bitcoin wallets set up by the Wannacry creators would never be moved, because there was so much attention focused on who was behind the attack.
Moving the cash might expose key details about the attackers that could be used to track them down.
But the bitcoins were moved earlier this week and some were piped to an exchange network called Shapeshift.io in an attempt to convert them to another virtual currency called Monero.
The Monero crypto-currency was set up to be more anonymous than Bitcoin and seeks to hide as much information as possible about every transaction.
