If this has been true a lot of big companies or govenrment files or private files has been a victim of this said cryptomining criminals or cyberspace criminals already. Having said so it it really occured this will surely make headlines in the local and international media. So far there has been no reports whatsoever linking to this speculative article over any crimes committed all over the world. These of which I believe is another form of attact against bitcoin. Again and again bitcoin and many other popular altcoins will encounter such negative speculations to alter the mind of the people to stray away from cryptocurrencies this way they can cut their loses. Eversince cryptocurrencies has boom the banks has been hit significantly and they were hit hard. So for me this is just to spread panic and there is no truth in this article.
