Historical Context

Understanding the historical context of cyber attacks on elections is crucial for developing effective defences. Over the past decade, numerous incidents worldwide have exposed vulnerabilities in electoral systems and the lengths to which adversaries will go to influence democratic processes.

Early Instances of Election Interference

Cyber attacks targeting elections are not a new phenomenon. An early instance, such as the 2011 cyber operation during the Taiwan election, demonstrated how state-sponsored actors could disrupt national infrastructure and compromise sensitive political information. According to the Taipei Times, the email accounts of senior politicians from the Taiwanese Democratic Progressive Party (DPP) were compromised by foreign hackers. The Deputy Director of the DPP’s Research Committee linked the attacks to the presidential and legislative elections scheduled for January 2012

The 2016 US Presidential Election

One of the most prominent examples of election interference occurred during the 2016 US Presidential Election. Cyber attackers, believed to be state-sponsored, engaged in activities ranging from hacking into political party servers to launching disinformation campaigns on social media. According to cyber-security firm Trend Micro, a foreign hacking group Pawn Storm released several months’ worth of data stolen from the US Democratic National Committee (DNC). The data was collected by a Gmail credential phishing campaign targeting political staff from both the Clinton and Obama campaigns. It was released in two sets: the first by Guccifer 2.0 and DCLeaks.com, and the second by WikiLeaks just before the Democrats' national convention

Lessons from the UK

The UK has also faced attempts at election interference. In 2017, reports surfaced about potential foreign interference in the Brexit referendum, highlighting the need for robust cyber-security measures to protect electoral integrity. Although there was no concrete evidence of direct hacking into voting systems, the influence of disinformation and social media manipulation raised concerns about the resilience of the UK's democratic processes.

Recent Developments

Recent years have seen an increase in both the sophistication and frequency of cyber attacks targeting elections. Advances in artificial intelligence and machine learning have enabled attackers to create more convincing phishing emails, deepfake videos, and automated bots that can spread disinformation at an unprecedented scale. The COVID-19 pandemic has further complicated the landscape, with more voters relying on digital systems for information and voting, thus expanding the attack surface.

Importance of Historical Context

By examining these historical examples, we can identify patterns and common tactics used by cyber attackers. This understanding is essential for developing proactive defense strategies and ensuring that the UK's electoral systems are resilient against both current and future threats. As we move forward, it is imperative to build on these lessons and continuously adapt our cyber-security measures to safeguard the democratic process.

Common Cyber Threats to Elections

Elections are complex events involving numerous interconnected systems and processes, making them prime targets for a variety of cyber threats. Understanding these threats is essential for developing effective defence strategies. Below are some of the most common and sophisticated cyber threats to elections:

Phishing and Spear-Phishing Attacks

• Description: Phishing involves sending deceptive emails to trick individuals into revealing sensitive information or installing malware. Spear-phishing is a more targeted form of phishing that customizes messages for specific individuals or organisations.
• Impact: Successful phishing attacks can compromise voter databases, election officials' credentials, and other sensitive information, leading to unauthorised access to election systems, voter fraud, and disruption of the electoral process.
• Increasing Sophistication: Attackers are increasingly using advanced social engineering techniques, making phishing attempts more convincing and harder to detect. The use of AI enhances the customization and believability of phishing emails, increasing the success rate of these attacks.

Distributed Denial of Service (DDoS) Attacks

• Description: DDoS attacks flood a network, server, or website with excessive traffic, rendering it unavailable to legitimate users.
• Impact: DDoS attacks can disrupt election websites, preventing voters from accessing information, voter registration services, or reporting systems. This can cause confusion, delays, and potentially disenfranchise voters.
• Operational Disruption: Downtime from DDoS attacks can have significant implications, especially if critical services are disrupted during peak election periods.

Ransomware

• Description: Ransomware is malicious software that encrypts a victim's data and demands a ransom for the decryption key.
• Impact: A ransomware attack on election infrastructure can disrupt voting systems, voter registration databases, and reporting systems, potentially delaying or compromising the integrity of the election.
• Evolution of Tactics: Modern ransomware attacks involve not just data encryption but also data theft, where attackers threaten to release stolen data unless the ransom is paid, adding an extra layer of coercion.

Supply Chain Attacks

• Description: Supply chain attacks target less secure elements within the supply chain of election technology providers to infiltrate more secure systems.
• Impact: Compromising a single vendor can lead to widespread breaches across all clients using that vendor's services, including election systems. This can result in manipulated software, hardware, or data used in the election process.
• Interconnectivity Risks: As election systems increasingly integrate with third-party services for efficiency and innovation, they inadvertently expand their attack surface.

Insider Threats

• Description: Insider threats involve individuals within an organisation who misuse their access to harm the organisation, either intentionally or unintentionally.
• Impact: Election officials, staff, or contractors with access to sensitive systems and data can inadvertently or maliciously compromise election security. This can include tampering with voter data, disrupting operations, or leaking confidential information.
• Access and Knowledge: Insiders have legitimate access and an understanding of the organisation’s cyber-security practices, making their actions potentially more damaging.

Disinformation and Misinformation Campaigns

• Description: Disinformation involves deliberately spreading false information to deceive, while misinformation is the unintentional spread of false information.
• Impact: Disinformation and misinformation campaigns can undermine public confidence in the electoral process, influence voter behaviour, and create confusion about election procedures and results. Social media platforms are often used to amplify these efforts.
• Increasingly Convincing Scams: With more personal information publicly available, disinformation campaigns can be highly customized and convincing, increasing their impact.

Advanced Persistent Threats (APTs)

• Description: APTs are prolonged and targeted cyber attacks where an intruder gains access to a network and remains undetected for an extended period.
• Impact: APTs can be used to infiltrate and manipulate election systems, steal sensitive data, and conduct surveillance. The stealthy nature of APTs makes them particularly dangerous as they can operate unnoticed for long periods, causing significant damage.
• Stealth and Longevity: APTs typically gain access through little-noticed vulnerabilities and maintain a presence in the network for months or even years, avoiding detection.

By recognising these common and sophisticated cyber threats, stakeholders can better prepare and implement robust security measures to protect the integrity of elections. The next section will delve into specific strategies and best practices for defending against these threats.

Guidance for High-Risk Individuals on Protecting Your Accounts and Devices

The UK NCSC has published guidance on protecting high-risk individuals.

What is a High-Risk Individual?

In a cyber-security context, you are considered a high-risk individual if your work or public status means you have access to, or influence over, sensitive information that could be of interest to nation-state actors. High-risk individuals include those working in political life (elected representatives, candidates, activists, staffers), academia, journalism, and the legal sector.

How and Why You May Be Targeted

There are different ways an attacker may gain access to your accounts or devices. Spear-phishing is one method that attackers have used in the past to compromise high-risk individuals. For more information of phishing attacks please read this article.

Using This Guidance

This guidance will help you improve the security of personal accounts and devices and keep you better protected online. Personal accounts and devices are the responsibility of the individual and may be considered an easy target for threat actors, as they may perceive them to have fewer security measures in place. As far as possible, you should continue to use corporately managed accounts and devices for your work, as they will be centrally managed and secured.

Protecting Your Accounts

Your personal accounts are a likely target for attackers. If an attacker gains access to one of your accounts, they may be able to access the information on them. Taking the actions below will significantly reduce the chance of a successful attack:

• Use strong passwords.
• Enable two-step verification on your accounts.
• Review your social media use and settings.
• Review your use of messaging apps.
• Protecting Your Devices

As with your accounts, attackers may also try to compromise your devices – computers, phones, or tablets – to achieve their aims. If they manage to access them, they can steal sensitive or personal information, carry out monitoring, or even impersonate you.

There are several things you can do to secure your devices:

• Install updates.
• Use 'Lockdown Mode'.
• Replace old devices.
• Protect physical access.
• Know how to erase data from devices.

What to Do If You Think You've Been Attacked

If you receive a suspicious email, do not click on any links or reply to the email until you're certain the sender is genuine. You should report it to your organisation's IT support, who will be able to offer advice, even if it has been sent to a personal account.

f you have clicked on a link or think you’ve been hacked, don’t panic, even if you think you have made a mistake. If something goes wrong on a device or account that your organization has provided, report it to IT support. The security team shouldn’t blame you for reporting that something has happened to you, as it helps them fix things and try to stop it happening again, to you or anyone else.

Individual Cyber Defence Services

To provide additional support to high-risk individuals, the UK NCSC is offering two opt-in services:

• Account Registration: The NCSC Account Registration service is available to all election candidates, elected officials, and party leaders. Subscribers will receive incident notifications if the NCSC becomes aware of a cyber incident impacting a personal account. It also highlights additional security features from the industry that can further protect personal accounts.
• Personal Internet Protection (PIP): The NCSC Personal Internet Protection (PIP) service adds an extra layer of security against spear-phishing, by protecting you from accessing known malicious domains on your personal devices. When you browse the internet or use mobile apps, PIP checks the domains you visit against a known malicious list. If the domain is on the block list, your device will show a warning. If your device is already infected with malware, PIP will block outgoing traffic to known malicious IP addresses and domains, to prevent you from accessing websites that host or link to malware and other cyber threats.

If you believe you are a high-risk individual, please contact candidates2024@ncsc.gov.uk. Please provide your full name and a short business case.
