On Saturday, police forces from Spain and the UK broke up a cyber-crime ring that led to five arrests.
The five detainees, two from the UK and three from Spain, were suspected of designing and selling malicious software tools online in an effort to discover banking and finance details of unsuspecting victims.
The malicious software containing backdoor viruses and keyloggers was sold on hacking forums in exchange for payments in Bitcoin.
Europol coordinated the arrests of those in the cyber-criminal ring who had allegedly been operating since 2013 and had a substantial financial return.
Police raided several properties in Barcelona, the Canary Islands and Liverpool where they took six hard drives, a laptop, an external hard drive, two external storage devices, eight Bitcoin mining devices and bank account details.
A police statement read, “National Police agents have dismantled an international group of cyber-criminals specialising in the design, development and marketing of sophisticated tools to provide invisibility (encryption) to all kinds of malware to infect thousands of computers worldwide.”
