JOHANNESBURG: Bitcoin is losing its lustre with some of its earliest and most avid fans – criminals – giving rise to a new breed of virtual currency.
The value of certain privacy-focused digital currency like monero, designed to avoid tracking, have climbed faster over the past two months as law enforcers adopt software tools to monitor people using bitcoin.
A slew of analytic firms such as Chainalysis are getting better at flagging digital hoards linked to crime or money laundering, alerting exchanges and preventing conversion into traditional cash.
The European Union’s law-enforcement agency, Europol, raised alarms three months ago, when it reported that “other cryptocurrencies such as monero, ethereum and Zcash are gaining popularity within the digital underground”.
Online extortionists, who use ransomware to lock victims’ computers until they fork over a payment, have begun demanding those currencies instead.
On December 18, hackers attacked up to 190,000 WordPress websites per hour to get them to produce monero, according to security company Wordfence.
For ransomware attacks, monero is now “one of the favourites, if not the favourite”, said Matt Suiche, the founder of Dubai-based security firm Comae Technologies.
Monero quadrupled in value to US$349 in the final two months of 2017, according to coinmarketcap, placing it among a number of upstart coins that rose faster than bitcoin, the world’s most valuable digital currency.
Bitcoin roughly doubled in the same period, according to data compiled by Bloomberg.
