By 2025, all the data people generate, from dating apps to video streaming, will add up to 175 zettabytes! Securing this vast trove of information is imperative and this exponential growth in data underscores the critical need for robust cybersecurity measures across sectors. Now, that includes the rapidly growing sector of grid-connected, inverter-based resources (IBR) for large-scale solar and behind-the-meter distributed energy resources (DER).
The solar industry, like many others, is increasingly becoming a target for cyberattacks. Given the complex nature of solar projects involving multiple stakeholders and digital systems, EPC firms are particularly vulnerable. Understanding and mitigating these threats is crucial for the integrity and reliability of your infrastructure.
Solar power systems, while environmentally beneficial and increasingly cost-effective, are not immune to cyber threats. Integrating smart-grid technologies, energy management systems (EMS), mobile applications, and cloud-based control systems poses several risks, including new cyberattack vectors for the electric grid, expanded attack surfaces, and the potential for malicious control of IBR/DER systems via the Internet. These vulnerabilities pose a significant threat to local operations and large-scale grid reliability.
Let's begin with the basics first.
When we say, “solar system hacking”, you might picture a professional black hat hacker in a hoodie, sitting in a dimly lit room, furiously typing lines of code into a computer. In reality, solar cyberattacks are much more mundane and rely on exploiting human errors and outdated technologies. Basically, hacking a solar panel or PV system involves exploiting vulnerabilities in the components and networks that manage solar energy production and distribution.
Of course, there are numerous deceptive techniques to cyberattack a solar system, but notably, advanced hackers use “zero-day” attacks, that target previously unknown vulnerabilities. These attacks are particularly dangerous because there is no immediate defense against them!
Understand this context with a simple example - A hacker might discover a flaw in the communication protocol between your solar PV system and the central management system. Now, this allows them to intercept and alter data, leading to incorrect power distribution or damaging the panels. So, it’s not just about stealing your data. It can have serious physical and operational consequences.
In essence, hacking a solar panel means exploiting weaknesses in both the digital and physical components of your system; resulting in disrupted power generation, operational inefficiencies, and potential physical damage.
As you read earlier, hackers exploit specific vulnerabilities in solar PV systems to disrupt your operations and compromise data. In fact, 2023 saw a 23% increase in cybercrime reports in Australia alone, equivalent to one report every 6 minutes. It’s clear that Australia is becoming an increasingly attractive target for cybercrime and here's how they attack:
I. Infiltrating Inverters, to Manipulate the Power Flow:
By infiltrating vulnerable inverters, hackers manipulate power flow. This could lead to erratic energy output or complete shutdowns, impacting energy production and potentially causing huge financial losses to the EPC or solar energy provider. Further, hackers identify various weak points in inverters, such as outdated firmware or weak encryption protocols. So, these vulnerabilities may not be immediately apparent, requiring thorough cybersecurity assessments and continuous monitoring to detect and mitigate potential threats.
But the worst part is, compromised inverters can be used to gather sensitive operational data, providing insights into energy consumption patterns that can be exploited for further attacks, often without early detection.
II. Exploiting SCADA Systems to Breach Data:
SCADA (SupervisoryControl and Data Acquisition) systems manage and monitor solar farms' operations. Security gaps in SCADA systems make them prime targets for solar panel hackers seeking control or data breaches.
A successful breach can grant hackers control over solar farm operations, allowing them to manipulate settings, alter production schedules, or even cause physical damage to equipment. Without photovoltaic technology, satellites cannot recharge their batteries, rendering them inactive during cyberattacks that disrupt their power supply, potentially causing information blackouts.
Ultimately, data breaches in these SCADA systems could expose sensitive operational data, compromising the integrity and confidentiality of solar energy operations.
III. Social Engineering to Control Human Vulnerabilities:
Hackers often employ social engineering tactics to exploit human vulnerabilities within solar energy companies. Through phishing emails or phone calls, they trick employees into divulging sensitive information or clicking on malicious links. Once inside the network, hackers can escalate and install malware to exfiltrate valuable data.
Let's consider a scenario: A project manager from your organization receives a seemingly urgent email from a known supplier. The email contains a link to a shared document, which the manager clicks, unknowingly downloading malware. The hackers then use this access to monitor network activities, escalate privileges, and steal sensitive project data, ultimately compromising your operations and reputation.
So, the impact of a successful social engineering attack can range from unauthorized access to critical systems to data theft or system disruption, affecting the entire trust within your organization!
IV. Distributed Denial of Services (DDoS):
You must have read about DDoS for banks. But this is also applicable to photovoltaics. Hackers identify specific solar systems as potential targets based on vulnerabilities in their network infrastructure or operational processes. During the preparation phase, they either go with:
a. Reconnaissance: Hackers gather information about the target PV system, including its IP addresses, network architecture, and operational protocols.
b. Botnet Setup: Hackers assemble a botnet, a network of compromised computers or devices, capable of generating large volumes of traffic.
With that the botnet gets activated - Hackers deploy the botnet to simultaneously send high volumes of traffic towards the target PV system's IP addresses or domain names. And the botnet starts generating traffic in various forms (HTTP requests, UDP floods, SYN floods, etc.), overwhelming your PV system's network infrastructure. Ultimately, this influx of malicious traffic saturates the PV system's bandwidth, server capacity, and other network resources, making it difficult or impossible for legitimate users to access the system!
In a notable incident in 2022, several solar systems experienced targeted DDoS attacks aimed at their control systems. These attacks flooded the networks with malicious traffic, resulting in operational downtime. Although the attackers did not manage to exfiltrate sensitive data, the incidents underscored vulnerabilities in the network defenses of solar PV systems.
Customers should always feel trusted in your installations and services. It's crucial to keep your systems and servers completely confidential and cyber-secure. Think of it as safeguarding your business's backbone. A breach could mean losing crucial data, facing hefty fines, and damaging your hard-earned reputation. And current vulnerabilities in IBR/DER equipment highlight the urgent need for improved security measures like:
• Field Equipment Hardening: For unencrypted storage and default/generic passwords allow unauthorized access.
• Network Protection & Monitoring: For lack of encryption for data-at-rest or in-transit and insufficient network segmentation.
• Incident Response: For ineffective use of Security Information and Event Management (SIEM) systems and lack of proper incident handling protocols.
In the renewable energy sector, trust is everything. Securing your systems not only protects against risks but also shows your commitment to reliability. Approaches like these not only ensure better installations for homeowners but also strengthen your business in the long run.
To this end, it is now clear that solar cybersecurity is not just a 'want' but a crucial 'need' (for three chief reasons) that many companies are still overlooking:
1) National Security: A reliable power grid is essential for national security. Cyberattacks on solar could cripple critical infrastructure.
2) Economic Impact: Power outages cost businesses and individuals dearly. Cybersecurity protects the solar industry's economic well-being.
3) Widespread Disruptions: A single attack on a large solar farm could cause cascading blackouts, impacting millions.
The stakes are high. Cyberattacks on solar infrastructure can have far-reaching consequences, from disrupting power supply to compromising national security. Given the increasing frequency of these attacks, prioritizing cybersecurity is no longer an option but a necessity. So, act early and safeguard your EPC firm!
Keep your solar business safe and sound with these essential cybersecurity tips.
While 48% of all SMBs have experienced a cyberattack, 43% of them have challenges understanding what security is actually required! This highlights a critical gap in cybersecurity preparedness across businesses of all sizes. And for industries like solar energy, where the rapid adoption of digital technologies is transforming operations, these are 6 fundamental, yet highly critical tips towards protecting your clean energy:
