Top 5 Cyber Security Threats to US Critical Infrastructure in 2023

In today’s interconnected world, critical infrastructure plays a pivotal role in the functioning of any nation. The United States, being a global leader, heavily relies on its critical infrastructure organizations to sustain its economy and ensure national security. However, this interconnectedness also exposes the country to a myriad of cyber threats. In this article, we will explore the top five cyber security threats to US critical infrastructure and understand how you can safeguard your organization from these cyber threats.

1. Ransomware

Ransomware has emerged as a pervasive and damaging threat to the critical infrastructure of the United States, affecting a range of sectors, including financial institutions, healthcare, and educational institutions. Ransomware attacks typically involve encrypting an organization’s data or systems and demanding a ransom for the decryption key.

In recent years, attacks on financial institutions have seen an increase in sophistication, causing substantial financial losses. These attacks not only disrupt services but also undermine the trust that clients have in these institutions. Healthcare facilities have been plagued by ransomware, often resulting in the compromise of patient records and the interruption of critical medical services. Additionally, educational institutions have faced significant challenges, with attacks disrupting virtual learning platforms and exposing sensitive student and faculty data.

2. State-sponsored Disruptive and Destructive Threats

Critical infrastructure sectors such as energy and gas, utilities, and government websites have been targeted by state-sponsored threat groups from countries like China and Russia. These attacks range from disruptions of service to destructive operations that can lead to physical damage or prolonged outages. These threat groups often operate with the backing of their respective governments and pose a significant risk to the nation’s security.

For example, attacks on energy and gas sectors can disrupt the supply of power and essential resources, impacting the daily lives of citizens. Utility companies are also vulnerable targets; a successful attack on these organizations can lead to service outages that can affect entire regions. Attacks on government websites can compromise national security and citizen privacy. The destruction or manipulation of data or services within these organizations can have far-reaching consequences.

3. Third-Party Supply Chain Threats

Third-party supply chain threats are intricate challenges that arise from the interconnected nature of modern supply chains. Cybercriminals often exploit vulnerabilities in third-party entities to gain access to more secure critical infrastructure systems. These threats encompass several aspects, such as zero-day vulnerabilities, third-party suffering from cyberattacks, sensitive information exfiltration, and unauthorized remote desktop access.

Zero-day vulnerabilities are flaws in software or hardware that are unknown to the vendor and, therefore, unpatched. Threat actors can exploit these vulnerabilities through third-party entities to compromise critical infrastructure systems. Additionally, attacks on third-party entities themselves, such as ransomware and disruptive DDoS attacks, can have a ripple effect, disrupting the supply chain and, ultimately, critical infrastructure operations. Furthermore, the exfiltration of sensitive information can lead to data breaches, intellectual property theft, and other damaging consequences.

4. Social Engineering

Social engineering is a versatile and persistent threat that leverages psychological manipulation to trick individuals into divulging sensitive information or performing actions that compromise security. Threat actors use various tactics, such as phishing emails, calling help desks for password resets, SMS phishing (smishing), and QR code phishing to exploit human psychology and gain unauthorized access to systems and data.

Phishing emails are one of the most prevalent forms of social engineering. These emails often impersonate trusted entities, tricking recipients into clicking on malicious links or attachments. Calling help desks for password reset attacks involve impersonating employees or users to gain access to accounts. SMS phishing sends fraudulent text messages that lead recipients to malicious websites or reveal personal information. QR code phishing involves manipulating QR codes to redirect users to malicious sites or download malicious apps.

5. Insider Threats

Insider threats are a significant concern for US critical infrastructure, as they involve individuals with authorized access who intentionally or unintentionally pose risks to the organization’s security. These insiders may be negligent, careless, or intentionally malicious in their actions. Insider threats can encompass a range of activities, including data theft, fraud, espionage, or unintentional errors that compromise security.

Negligent insiders may unknowingly create vulnerabilities, such as failing to follow security protocols, sharing passwords, or clicking on malicious links. Careless insiders may mishandle sensitive data, leading to accidental data breaches. Malicious insiders may intentionally steal data, sabotage systems, or conduct espionage on behalf of external threat actors. All these activities can significantly impact critical infrastructure operations and security.
