Cyber Espionage

Cyber espionage threat landscape, ENISA



Overview

Cyber espionage is considered both a threat and a motive in the cybersecurity playbook. It is defined as ‘the use of computer networks to gain illicit access to confidential information, typically that held by a government or other organisation’.

In 2019, many reports revealed that global organisations consider cyber espionage (or nation-state-sponsored espionage) a growing threat affecting industrial sectors, as well as critical and strategic infrastructures across the world, including government ministries, railways, telecommunication providers, energy companies, hospitals and banks.

Cyber espionage focuses on driving geopolitics, and on stealing state and trade secrets, intellectual property rights and proprietary information in strategic fields. It also mobilises actors from the economy, industry and foreign intelligence services, as well as actors who work on their behalf. In a recent report, threat intelligence analysts were not surprised to learn that 71% of organisations are treating cyber espionage and other threats as a ‘black box’ and are still learning about them.

In 2019, the number of nation-state-sponsored cyberattacks targeting the economy increased and it is likely to continue this way.

In detail, nation-state-sponsored and other adversary-driven attacks on the Industrial Internet of Things (IIoT) are increasing in the utilities, oil and natural gas (ONG), and manufacturing sectors.

Furthermore, cyberattacks conducted by advanced persistent threat (APT) groups indicate that financial attacks are often motivated by espionage. Using tactics, techniques and procedures (TTPs) akin to those of their espionage counterparts, groups such as the Cobalt Group, Carbanak and FIN7 have allegedly been targeting large financial institutions and restaurant chains successfully.

The European Parliament’s Committee of Foreign Affairs called upon Member States to establish a cyber-defence unit and to work together on their common defence. It stated that ‘the Union’s strategic environment has been deteriorating … in order to face the multiple challenges that directly or indirectly affect the security of its Member States and its citizens; whereas issues that affect the security of EU citizens include: armed conflicts immediately to the east and south of the European continent and fragile states; terrorism – and in particular Jihadism –, cyberattacks and disinformation campaigns; foreign interference in European political and electoral processes’.

Threat actors motivated by financial, political, or ideological gain will increasingly focus attacks on supplier networks with weak cybersecurity programs. Cyber espionage adversaries have slowly shifted their attack patterns to exploiting third- and fourth-party supply chain partners.

Mitigation measures

Because of the comprehensive nature of this threat, several of the mitigation measures recommended for other threats in this report could be employed as part of the following baseline mitigation controls:

- Identify mission critical roles in the organisation and estimate their exposure to espionage risks. Evaluate such risks based on business information (i.e. business intelligence).

- Create security policies that accommodate human resource, business and operational security controls to cater for risk mitigation. These should include rules and practices for awareness raising, corporate governance and security operations.

- Establish corporate practices to communicate, train staff in the rules developed.

- Develop an evaluation criteria (KPIs) to benchmark the operation and adapt it to upcoming changes.

- Create a Whitelist for critical application services depending on the risk level assessed.

- Assess vulnerabilities and patch the software regularly, especially for systems that are on the perimeter.

- Implement the need-to-know principle for defining access rights and establish controls to monitor misuse of privileged profiles.

- Establish content filtering for all inbound and outbound channels (e.g. email, web, network traffic).
