Unsurprisingly, Coinhive has been the center of attention in the past few weeks, and the tool has been both praised and ripped apart. While the solution that Coinhive offers is very interesting, the trust might have been lost for good as ad-blockers and anti-malware tools have already started blocking the miner. If the ad-blocker is activated, the owner of the website – or the party controlling the miner via it – is not going to earn any money. If anti-malware software detects the miner, the website could be blocked altogether. It is highly likely that this and other known cryptocurrency miners will be exploited by malicious parties trying to make money, and already-existing malware (e.g., tech-support scams, adware, hijackers, and redirectors) could employ the miner to serve them as well.
There is still a lot to learn, and things could develop in unexpected ways, but in the meantime, website owners are advised to stay careful and vigilant so as not to overlook any breaches linked to the unauthorized placement of the Coinhive miner. Website visitors also need to be vigilant because visiting sites where the miner is active could lead to high usage of CPU resources.
