Roughly one year ago, KrebsOnSecurity published a lengthy investigation into the individuals behind Coinhive[.]com, a cryptocurrency mining service that has been heavily abused to force hacked Web sites to mine virtual currency. On Tuesday, Coinhive announced plans to pull the plug on the project early next month.
A story published here this week revealed the real-life identity behind the original creator of Coinhive — a controversial cryptocurrency mining service that several security firms have recently labeled the most ubiquitous malware threat on the Internet today. In an unusual form of protest against that story, members of a popular German language image-posting board founded by the Coinhive creator have vented their dismay by donating tens of thousands of euros to local charities that support cancer research.
On Monday KrebsOnSecurity published Who and What is Coinhive, an in-depth story which proved that the founder of Coinhive was indeed the founder of the German image hosting and discussion forum pr0gramm[dot]com (not safe for work). I undertook the research because Coinhive’s code primarily is found on tens of thousands of hacked Web sites, and because the until-recently anonymous Coinhive operator(s) have been reluctant to take steps that might curb the widespread abuse of their platform.
Multiple security firms recently identified cryptocurrency mining service Coinhive as the top malicious threat to Web users, thanks to the tendency for Coinhive’s computer code to be used on hacked Web sites to steal the processing power of its visitors’ devices. This post looks at how Coinhive vaulted to the top of the threat list less than a year after its debut, and explores clues about the possible identities of the individuals behind the service.
