[SingCERT] Alert on Browser-based Digital Currency Mining
09 November 2017
SingCERT has seen an increase in digital mining tools embedded in websites to secretly mine digital currency. These websites expend the user's Central Processing Unit (CPU) power without their permission.
Digital Currency is a form of currency that exists only in digital form, unlike traditional physical currency such as banknotes and coins. Digital currency is digitally created, held and transacted electronically through transfers of value on computer networks. Digital currencies are generated by mining software that run on computer systems on the internet, making use of the computational power of the hardware Central Processing Unit (CPU) and Graphics Processing Unit (GPU). Bitcoin, Monero and Ethereum are examples of digital currencies that make use of hardware computational power for digital mining.
