The principal British financial institutions, together with American banks, are this month preparing to take part in “Operation Resilient Shield”, a simulated large-scale cyberattack involving hostile state forces whose sole purpose would be to destabilise the financial and banking capacities of the two allies.

Particular emphasis will be placed on the communication between the various financial institutions and their respective governments. Announced last January by David Cameron and Barack Obama, the operation will be coordinated by the national Computer Emergency Response Teams of the two countries.

This is not the first time that an operation of this type has been organised in the United Kingdom. In 2011, and again in 2014, “Walking Shark” exercises were based on the same scenario, in which the British banking sector was targeted by attacks designed to cause it serious damage. These exercises included attacks using Distributed Denial of Service (DDoS), or more sophisticated Advanced Persistent Threat (APT) attacks.

The exercise is thus based on the political and national defence dimensions of computer security in the financial sector. Although that sector is particularly targeted by hackers who are mainly motivated by financial gain, it is also a target for States which possess advanced information technology resources and may have an interest in financially destabilising another State.
