IT Security Update: Cryptojacking

What is Cryptojacking?

The National Cyber Security Centre’s report on ‘The Cyber Threat to UK Business’ identifies cryptojacking as an emerging threat.  Cryptojacking has already impacted on an estimated 55% of businesses worldwide. The name is play on the Americanism ‘car-jacking’ but instead of your car being stolen your computing processing power is the criminals target of choice.

The recent dramatic surge in value of cryptocurrencies such as Bitcoin and Monero has likely fuelled the parallel rise in cryptojacking.  It aims to which harness unsuspecting users computing power for the sole purpose of ‘mining’ cryptocurrencies.

While cryptojacking itself is not new, its latest incarnation as code embedded in web-browsers is a significant development. Criminals infect a website with code which auto-executes once loaded on the victims’ browser. High profile web-sites including the UK Information Commissioners Office and Student Loans Company are recent victims.

Users browsing these legitimate sites become unknowing victims to this illicit crime. Often there is no outward sign that a users computer has been infected, decreasing performance and a rising electricity bill are most likely the only indicators that a cyber-crime is taking place. Criminals silently use the processing power to mine crypto-currency which they then sell for a profit.

Initially there is little impact on the victim however there are concerns that the criminals could easily adapt the code for a different purpose and potentially target your data, passwords etc.
