Catalin Cimpanu, reporting for BleepingComputer: Ever since mid-September, when Coinhive launched and the whole cryptojacking frenzy started, the Internet has gone crazy with in-browser cryptocurrency miners, and new sites that offer similar services are popping up on a weekly basis. While one might argue that mining Monero in a site's background is an acceptable alternative to viewing intrusive ads, almost none of these services that have recently appeared provide a way to let users know what's happening, let alone a way to stop mining behavior. In other words, most are behaving like malware, intruding on users' computers and using resources without permission. [...] Bleeping Computer spotted two new services named MineMyTraffic and JSEcoin, while security researcher Troy Mursch also spotted Coin Have and PPoi, a Coinhive clone for Chinese users. On top of this, just last night, Microsoft spotted two new services called CoinBlind and CoinNebula, both offering similar in-browser mining services, with CoinNebula configured in such a way that users couldn't report abuse. Furthermore, none of these two services even have a homepage, revealing their true intentions to be deployed in questionable scenarios.
