Since we last reported on a version of the ELF Linux/Mirai malware containing cryptocurrency coin-mining tools in April, the IBM X-Force has noticed a steep increase in the volume of coin central processing unit (CPU) mining tools used in cyberattacks, specifically those targeting enterprise networks.
According to IBM Managed Security Services (MSS) data, there have been peaks reaching more than a sixfold increase in attacks involving embedded mining tools in the eight-month period between January and August 2017. This is not surprising, since a recent third-party report noted that detections for cryptocurrency mining Trojans has risen significantly in the last few years.
