A military unit of State B conducts a cyber espionage operation against State A’s Ministry of Foreign Affairs and its subordinate organizations. The data obtained in this operation is later published on the internet by State B.
The analysis considers whether State B’s operation violated sovereignty, the prohibition of intervention, and diplomatic and consular law. What measures, if any, can the victim State lawfully take in response?
Scenario[edit | edit source]
Keywords[edit | edit source]
Attribution, peacetime cyber espionage, diplomatic and consular law, prohibition of intervention, sovereignty, privacy
Facts[edit | edit source]
[F1] State A discovers that an email server and several other servers belonging to its Ministry of Foreign Affairs (MFA) have been infiltrated. (The MFA system is a closed system located in the territory of State A, with missions staff using VPN connection to access it.) Initially, the attackers are not identified. Investigation shows that the attackers gained access to the email server by obtaining passwords of several consular officers at State A’s missions abroad through spear phishing and fake log-on websites (incident 1).
[F2] After gaining access, the intruders escalated account privileges and moved laterally through the network, which includes servers located both within State A's territory and on diplomatic and consular premises abroad. Within a few days, they gained access to additional MFA network servers and services provided in various countries abroad. They had access to data of various MFA personnel including senior officials for several months (incident 2).
[F3] A large amount (over 10 GB) of unclassified data on MFA servers was exfiltrated, even though it is not immediately clear what precise data was affected by the incident (incident 3). No data was destroyed or encrypted and no MFA services were affected during the attack.
[F4] Nobody claims responsibility for the attack immediately after the MFA's discovery of the incident and publication of the fact that it has occurred. However, a few days later, emails, procurement documents, and internal memos belonging to the MFA of State A are published on the internet (incident 4).
[F5] Multiple evidence points to State B:
- Technical investigation revealed the malware used by attackers in this case. The same malicious code was employed in the past during multiple campaigns by an entity affiliated with a military unit of State B. One of those campaigns was targeted against State C’s MFA.
- Earlier on, head of an allied intelligence service in State C had publicly accused State B of a cyber espionage campaign conducted by the state military unit against State C’s MFA.
- The attackers used tactics, techniques and procedures (TTPs) very similar to those observed in other attacks publicly attributed to State B by multiple countries including State A allies. Mimicking TTPs is much more difficult than tampering with other technical elements.
- Judging by the nature and content of the compromised data and by persons who were apparently of particular interest to the attackers, State A cybersecurity authority indicated State B as a logical and the most probable perpetrator of the attack against the MFA.
- State A intelligence service sources confirmed that State B institutions possessed information that was based on State A MFA’s internal data that was not in the public domain.
[F6] Both State A and State B are parties to the Vienna Convention on Diplomatic Relations (VCDR)[1] and the Vienna Convention on Consular Relations (VCCR).[2]
Examples[edit | edit source]
- SuperMicro supply chain breach (since 2010)
- Office of Personnel Management data breach (2015)
- APT-29 attacks on ministries (2016-2017)
- Chinese infiltration into EU parliamentary proceedings (2018)
- SolarWinds (2020)
- Spear-phishing attack against UK parliamentarianss (2021-2022)
Legal analysis[edit | edit source]
For a general overview of the structure of analysis in this section, see Note on the structure of articles.
[L1] The legal analysis focuses on a number of relevant international legal rules, including the obligation to respect the sovereignty of other States, the prohibition of intervention, inviolability under diplomatic law and privacy rights.
Attribution[edit | edit source]
State organs and persons and entities in exercise of governmental authority |
---|
Such conduct is attributable to the State even if the organ, person or entity acting in that capacity "exceeds its authority or contravenes instructions" (acts ultra vires).[6] |
[L2] The military unit of State B qualifies as an organ of that State.[7] As such, its relevant conduct is directly attributable to State B.[8] The following analysis proceeds on the assumption that all activities described in the scenario (incidents 1–4) were conducted by the said State B’s military unit and are therefore attributable to it.
Breach of an international obligation[edit | edit source]
Diplomatic and consular law[edit | edit source]
Inviolability of documents and archives of diplomatic missions and consular posts |
---|
[L3] In incident 1, by gaining access to the official email accounts of several consular officers of State A, State B ran afoul of the inviolability of official correspondence under diplomatic and consular law. The lateral movement (incident 2) and exfiltration of data (incident 3) are just further steps in the illegal activity of State B, at least to the extent that the hacked accounts and servers contained data pertaining to State A’s diplomatic missions and consular posts, irrespective of their location.[12] This is because international law grants the inviolability of any official correspondence related to the missions and its functions. [13]
[L4] Incident 4, wherein the data was published on the internet, raises the question whether the published materials are still protected by international law under diplomatic and consular law. This issue is unsettled in the present state of the law. One view, endorsed by a majority of the experts drafting the Tallinn Manual, is that inviolability no longer applies to data that has been made public, as it is “not confidential as a matter of fact”.[14] By contrast, others believe that the duty to respect the inviolability of the materials in question continues to apply in such cases.[15] The primary reason for this view is that the duty of inviolability covers the protected materials “wherever they may be”,[16] which therefore includes even the public domain.[17]
[L5] Nonetheless, there may be aspects of the right to privacy in the context of international human rights law which are violated by the publication of the consular officers' and other MFA personnel's personal details and additional information associated with their emails.[18]
Sovereignty[edit | edit source]
Sovereignty |
---|
Multiple declarations by the UN,[20] the African Union,[21] the European Union,[22] NATO,[23] OSCE,[24] and individual States have confirmed that international law applies in cyberspace. Accordingly, so too does the principle of sovereignty.[25] However, there is some debate as to whether this principle operates as a standalone rule of international law, the breach of which gives rise to state responsibility.
The remainder of this section proceeds on the basis of the former “sovereignty-as-rule” approach. Those espousing the latter “sovereignty-as-principle” approach should refer to other relevant sections of the legal analysis (such as that on the prohibition of intervention or use of force). It is understood that sovereignty has both an internal and an external component.[46] In the cyber context, the “internal” facet of sovereignty entails that “[a] State enjoys sovereign authority with regard to the cyber infrastructure, persons, and cyber activities located within its territory, subject to its international legal obligations.”[47][48] This encompasses both private and public infrastructure.[49] The external component entails that States are “free to conduct cyber activities in [their] international relations”, subject to their international law obligations.[50] As a general rule, each State must respect the sovereignty of other States.[51]However, within the cyber realm – and particularly regarding remote cyber operations – there is still no agreement on the criteria[52] and the required threshold[53] to qualify an operation as a sovereignty violation.[54] It is clear that a cyber operation with severe destructive effects, comparable to a “non-cyber” armed attack or a use of force against a State, constitutes a violation of its sovereignty; however, with more subtle cyber operations, the question is far from settled.[55] Accordingly, the assessment needs to be done on a case-by-case basis.[56] The following modalities, highlighted in the Tallinn Manual 2.0, represent different ways of determining what a “sovereignty violation” might mean in the context of cyber operations:
The Tallinn Manual’s view of what constitutes a violation of sovereignty has been expressly endorsed by several States including Canada,[66] Germany[67] and the Netherlands;[68] and followed to some extent by other States, such as the Czech Republic,[69] Norway,[70] Sweden[71] and Switzerland.[72] An alternative test has been proposed by France, which argues that a breach of sovereignty occurs already when there is “any unauthorised penetration by a State of [the victim State’s] systems”;[73]similarly, Iran has argued that “unlawful intrusion to the (public or private) cyber structures” abroad may qualify as a breach of sovereignty.[74] Attributing the relevant cyber operation to a State different from the target State is a necessary prerequisite for qualifying the cyber operation as a violation of the target State's sovereignty. Whether non-State actors can violate territorial sovereignty on their own is a matter of disagreement.[75] Publicly available national positions that address this issue include:
|
[L6] Whether State A's sovereignty was violated in incidents 1–3 depends on whether the espionage operation was fully conducted from outside of State A’s territory, or whether a part of it was conducted by operators physically located in State A’s territory. In the latter case, the operation could be considered a violation of sovereignty, and hence State B’s breach of its corresponding international obligation (option 1 above).[76] As for a possible interference with data or services that are necessary for the exercise of "inherently governmental functions" (option 4 above), the data was merely copied by the adversary, not destroyed, deleted or modified, and the services were kept working during the espionage operation; hence the operation did not impair the exercise of the functions by State A.[77]
[L7] Taken separately, the publication of the acquired data (incident 4) would not violate the sovereignty of State A (however, if the publication was done in order to coerce State A, it might be a prohibited intervention - see below). Had the published information been classified in State A, then the publication is likely illegal according to State A’s domestic law; State A can also be a party to international agreements which regulate the transfer of its classified information to third parties, which may create obligations for third States with regard to this information.[78]
Prohibition of intervention[edit | edit source]
Prohibition of intervention |
---|
In order for an act, including a cyber operation,[81] to qualify as a prohibited intervention, it must fulfil the following conditions:[82]
Publicly available national positions that address this issue include:
|
[L8] In the present scenario, prohibited intervention could also be a relevant qualification. The incidents encroach on State A’s external affairs which are the sole prerogative of State A. However, incidents 1–3 (infiltration into State A systems and exfiltration of data) do not contain the requisite element of coercion, because they are conducted merely with the aim to gather information, which does not affect State A's ability to conduct its external affairs.[111]
[L9] As for incident 4 (publication of the data), if it can be attributed to State B, it could be coercive in the sense that it has the potential to cause State A to adapt its external (and internal) affairs based on the published information and to contain the relevant political damage. It may be harder for State A to ascertain the intent of State B, which might have had no particular outcome – i.e. effect on State A’s behaviour – in mind, apart from causing mischief. This might also pose an issue for establishing the causal nexus between State B’s activity and the resulting effect on State A's affairs: the causality might not be deemed direct enough.
Espionage[edit | edit source]
Peacetime cyber espionage |
---|
However, the methods of peacetime cyber espionage are varied and the legal consensus is almost non-existent with regard to cyber operations below the threshold of use of force or armed attack. It must be noted that although cyber espionage operations are generally not illegal from the perspective of international law, they are usually prohibited according to the domestic law of the target State. Moreover, the acting State’s authorities will also typically be subject to specific domestic law prescriptions pertaining to the conduct of foreign intelligence operations. Conversely, the mere fact that an operation is a cyber espionage operation does not make it legal in international law, according to a majority of the experts drafting Tallinn Manual 2.0.[113] According to a minority of the experts, espionage creates an exception for certain otherwise illegal cyber operations.[114] Publicly available national positions that address this issue include:
|
[L10] As this overview demonstrates, the mere characterization of a cyber operation as amounting to cyber espionage is not conclusive as to the question of its lawfulness under international law.[115] Reference must be had to specific rules of international law, which may be breached by the operation in question in its specific circumstances (see especially Sovereignty and Prohibited intervention above).
[L11] It may be noted that there is a view that acts of espionage represent a customary exception to the relevant prohibitions.[116] However, this interpretation would amount to the establishment of a novel circumstance precluding wrongfulness, for which there is no evidence in international law. Accordingly, the lawfulness of incidents 1–4 therefore must be assessed with reference to other applicable international legal rules.
Checklist[edit | edit source]
- Do the affected materials come under the duty of inviolability of documents and archives of diplomatic missions and consular posts?
- Do they implicate the right to privacy of affected personnel?
- Does the exfiltration and publication of data violate the sovereignty of the victim State?
- Does the exfiltration and publication of data amount to a prohibited intervention?
- Is the fact that part of the operation is peacetime cyber espionage an important circumstance for the il/legality of the operation? If so, to what extent?

While some States have stressed that economic coercion can still be sufficient for a breach of the rule of non-intervention, others remained ambiguous in their positions. States have referred to different examples that could be classified, depending on the circumstances of the case, under the prohibition of intervention. See the national positions of Australia (‘intervention in the fundamental operation of Parliament, or in the stability of States’ financial systems’), Canada (‘a malicious cyber activity that disrupts the functioning of a major gas pipeline, compelling the affected State to change its position in bilateral negotiations surrounding an international energy accord’), Italy (‘influence activities aimed, for instance, at undermining a State’s ability to safeguard public health during a pandemic’), New Zealand (‘a prolonged and coordinated cyber disinformation operation that significantly undermines a state’s public health efforts during a pandemic; and cyber activity deliberately causing significant damage to, or loss of functionality in, a state’s critical infrastructure, including – for example – its healthcare system, financial system, or its electricity or telecommunications network’), Norway (‘a cyber operation deliberately causing a temporary shutdown of the target State’s critical infrastructure, such as the power supply or TV, radio, Internet or other telecommunications infrastructure in order to compel that State to take a course of action’), Singapore (‘cyber-attacks against our infrastructure in an attempt to coerce our government to take or forbear a certain course of action on a matter ordinarily within its sovereign prerogative’), Switzerland (‘This is particularly true of economic coercion, which could be the case if a company that is systemically relevant was paralysed through a cyber operation’), the United Kingdom (‘intervention in the fundamental operation of Parliament, or in the stability of our financial system’; ‘to undermine the stability of another State’s financial system or to target the essential medical services of another State’; ‘Covert cyber operations by a foreign State which coercively restrict or prevent the provision of essential medical services or essential energy supplies […]disruption of systems controlling emergency medical transport (e.g., telephone dispatchers); causing hospital computer systems to cease functioning; disruption of supply chains for essential medicines and vaccines; preventing the supply of power to housing, healthcare, education, civil administration and banking facilities and infrastructure; causing the energy supply chain to stop functioning at national level through damage or prevention of access to pipelines, interchanges, and depots; or *preventing the operation of power generation infrastructure. Turning to economic stability, covert cyber operations by a foreign State that coercively interfere with a State’s freedom to manage its domestic economy, or to ensure provision of domestic financial services crucial to the State’s financial system, would breach the rule on non-intervention […] disruption to the networks controlling a State’s fundamental ability to conduct monetary policy or to raise and distribute revenue, for instance through taxation. Or disruption to systems which support lending, saving and insurance across the economy’), and the United States (‘a cyber operation that attempts to interfere coercively with a State’s ability to protect the health of its population –for example, through vaccine research or running cyber-controlled ventilators within its territories during a pandemic’).
