Now, the operators are gearing up to make more. >The unknown criminals generated the windfall over the past 18 months. The campaign has mainly exploited critical vulnerabilities on Windows computers and then, once gaining control over them, installing a modified version of XMRig, an open-source application that mines the digital coin known as Monero. While the group has used a variety of mining services, it has continued to dump the proceeds into a single wallet. As of last week, the wallet had received payouts of almost 10,829 Monero, which, at current valuations, are worth more than $3.4 million.
