Hackers hijacked computers to mine for cryptocurrency

Ars Technica reports that some YouTube ads were secretly running cryptocurrency mining scripts that consumed up to 80% of CPU resources.  PCMag.com states that Google blocked the ads shortly thereafter because these ads violated their terms of service.

The Seattle Times also reported on cases where computers on an employer’s network were running unauthorized software in order to mine for cryptocurrency – a process currently labeled “cryptojacking” by cybersecurity experts.

eWeek also noted that Docker containers may be vulnerable to cryptocurrency mining attacks.
