Ransomware has caused little more than heartache and disruption for the enterprise and consumers alike, but it may soon lose its lucrative appeal in favor of cryptocurrency miners.

Over the last few years, ransomware, which targets systems, encrypts files, and demands a blackmail payment in return for a potential decryption key, has hit the spotlight time and time again.

The UK's National Health Service (NHS), major shipping companies, utilities, private businesses, and consumers at large have all fallen prey to variants including Petya, WannaCry, GoldenEye, and CryptoLocker.

This type of malware capitalizes on unpatched PCs, legacy operating systems, and vulnerabilities both old and new.

However, according to Cisco Talos researchers, cryptocurrency miners may soon take the top spot as a way for fraudsters to generate income.

A Chrome extension with over 105,000 users has been deploying an in-browser cryptocurrency miner to unsuspecting users for the past few weeks.

The extension does not ask for user permission before hijacking their CPUs to mine Monero all the time the Chrome browser is open.

Webseitenbesucher für Crypto-Mining missbraucht

Der Boom um Kryptowährungen hält weiter an. Um an der zunehmenden Wertsteigerung teilzuhaben, missbrauchen manche Webseitenbetreiber sogar die Rechenleistung ihrer Nutzer für das Mining.

Die Anzahl der Webseiten mit Coinhive-Skript ist besonders in den letzten Monaten geradezu sprunghaft angestiegen.

Blockchain-basierte Währungen wie Bitcoin werden immer beliebter. Mehr und mehr Menschen wollen am enormen Wertanstieg der Digitaldevisen mitverdienen; und das auch mit teilweise fragwürdigen Mitteln. Relativ neu ist etwa das Ausnutzen der Rechenleistung von Webseiten-Besuchern zum Mining, also zum Generieren von Kryptowährungen.

Wie die Experten von Sophos beschreiben, ist dazu lediglich eine in JavaScript geschriebene Anwendung des Anbieters Coinhive notwendig. Ist diese in die Webseite integriert, wird das Tool beim Aufruf der Seite automatisch heruntergeladen. Und schon beginnt der Computer im Hintergrund die Kryptowährung Monero zu schürfen.

Some smart crooks found a way to insert and deliver the Coinhive in-browser miner inside ads delivered via the Google DoubleClick ad delivery platform.

Ads delivered this way made their way on countless sites, and even on Google's own property —YouTube.

A Trend Micro report released today claims the crooks behind this campaign started abusing Google's DoubleClick platform to deliver the Coinhive in-browser miner around January 18 and significantly ramped up operations on January 23.

What would you like with your latte? Cocoa? Cinnamon? Sprinkle of cryptocurrency mining piggybacking off your free Wi-Fi?

Recent visitors to a Buenos Aires Starbucks didn’t actually have a choice: instead, a 10-second delay was foisted on them when they connected to the coffee shop’s “free” Wi-Fi, as their laptops’ power secretly went to mine cryptocoins (of which the Starbucks customers received nary one slim dime, of course).

The mining was noticed by Stensul CEO Noah Dinkin, who took to Twitter on 2 December to ask Starbucks if it was aware of what was going on. He included a screenshot of the code.

Dinkin said in his tweet that the code was mining bitcoins, but it was actually CoinHive code, which offers a JavaScript miner for generating a cryptocurrency called Monero that’s an alternative to Bitcoin.
