Phishers are attempting to trick victims who lost their money as a result of the Mt. Gox collapse into installing malware on their computers.
Launched in 2010, Mt. Gox was a prominent Bitcoin exchange based in Tokyo, Japan that at one time handled approximately 70 percent of all transactions involving the popular cryptocurrency.
That all changed in 2014 when Mt. Gox filed for bankruptcy after admitting it had "lost" about 750,000 of its customers' Bitcoins and close to one million of its own Bitcoins.
The combined total of those losses amounted to about £283 million.
While authorities continue with their investigation into Mt. Gox's former CEO Mark Karpeles on charges of embezzlement and fraud, Bitcoin exchange Kraken is currently working to distribute $91 million to those who lost their money in the collapse.
Under Kraken's plan, tens of thousands of claimants will receive back a fraction of the moneys lost in the fiasco.
But if attackers have their way, those victims could lose even more.
As reported by The Register, researchers at the computer security firm Cyren recently spotted phishing emails that claim to originate from Kraken.
Each email directs users to a Google Doc page that masquerades as a list displaying the status of all claims relating to the Mt. Gox collapse.
In actuality, the email loads up W32/Trojan5.NRB, a form of malware which attempts to steal Bitcoins from available Bitcoin wallets.
To protect against this phishing scam, users should avoid clicking on links and downloading email attachments from untrusted sources. They should also be careful about launching suspicious executables on their computers.
For those who lost their Bitcoins as a result of the Mt. Gox collapse, you can check the status of your claim by visiting Kraken's claims portal.
