Introduction

The SolarWinds cyber attack, first disclosed in December 2020, marked one of the most significant cybersecurity breaches in history. It involved a sophisticated supply chain attack that compromised SolarWinds' Orion platform, affecting numerous organizations, including U.S. government agencies and major corporations. In the aftermath, the U.S. Securities and Exchange Commission (SEC) launched investigations to evaluate corporate responses to the breach, focusing on transparency and accurate risk disclosure.

In October 2024, the SEC announced fines totaling $7 million against four major technology companies—Unisys, Check Point Software Technologies, Mimecast, and Avaya Holdings—for misleading disclosures related to their involvement in the SolarWinds breach. These fines highlight a failure to uphold transparency, depriving investors and stakeholders of accurate information about the companies' exposure to the attack.

This case study explores the details of the SolarWinds attack, the response from the affected companies, the SEC’s findings, and the broader implications for corporate responsibility and cybersecurity disclosure practices.


The SolarWinds Attack: A Background

SolarWinds, a leading IT management software provider, was at the center of a nation-state espionage campaign allegedly orchestrated by a group linked to Russian intelligence. Hackers inserted malicious code into SolarWinds' Orion software updates, which were distributed to approximately 18,000 customers worldwide between March and June 2020.

The SolarWinds attack allowed cybercriminals to exploit backdoors in IT systems, gaining access to sensitive data and networks of major U.S. federal agencies, including the Treasury and Commerce Departments, and global corporations, such as Microsoft.

The breach raised alarm about the vulnerabilities in supply chain security, where trusted software vendors became unwitting conduits for sophisticated attacks. Following the breach, affected organizations were expected to report the extent of their exposure and the measures they were taking to mitigate risks. For publicly traded companies, transparent communication with investors about these risks was critical.


The SEC Investigation and Findings

The SEC’s investigation into the incident revealed that Unisys, Check Point, Mimecast, and Avaya were all impacted by the SolarWinds breach but failed to fully disclose the extent of their involvement. The SEC's allegations centered on misleading or incomplete disclosures made to investors, especially concerning the risks and consequences of the breach.

The specific SEC findings included:

  • Downplaying Material Cybersecurity Breaches: All four companies underplayed their exposure to the SolarWinds hack in public communications. This diminished investors’ understanding of the real impact of the breach on these companies.
  • Hypothetical Framing of Risks: The companies framed their cybersecurity risks hypothetically or generically, despite being aware that they had already been impacted by the SolarWinds breach.
  • Failure to Disclose Breach Involvement: By failing to promptly disclose the fact that they were breached, the companies deprived their investors of critical information needed to assess risks accurately.

These actions violated the SEC’s disclosure rules, which require companies to provide transparent and accurate information about material risks and incidents.


Fines and Settlement

In October 2024, the SEC issued fines against the four companies as follows:

  • Unisys: $4 million civil penalty
  • Avaya Holdings: $1 million civil penalty
  • Check Point Software Technologies: $995,000 civil penalty
  • Mimecast: $990,000 civil penalty

The companies agreed to settle the allegations without admitting or denying the SEC’s findings. While the fines themselves were substantial, the reputational damage caused by the misleading disclosures could have long-term consequences for these companies.


Company-Specific Failures

While all four companies were fined for misleading disclosures, their roles and involvement in the SolarWinds breach varied:

  • Unisys: As a major IT and consulting services company, Unisys had significant exposure to the breach due to its reliance on SolarWinds’ software for managing customer systems. Despite being directly impacted, the company downplayed the breach’s material effect on its business operations and customer relationships.
  • Check Point Software Technologies: As a leading cybersecurity provider, Check Point faced heightened scrutiny, given its responsibility to safeguard clients against attacks like SolarWinds. Its failure to adequately disclose its breach involvement raised questions about its internal cybersecurity practices.
  • Mimecast: Specializing in email security and data protection, Mimecast’s involvement in the SolarWinds breach was particularly concerning due to the sensitive nature of the data it handles. Mimecast’s underreporting of the incident could have undermined customer trust in its security solutions.
  • Avaya Holdings: Known for its communication technology services, Avaya’s reliance on SolarWinds software for managing parts of its infrastructure led to a breach. Like the others, it failed to provide timely disclosures to investors about the incident's scope.

Implications for Cybersecurity Disclosure Practices

This case underscores the importance of robust and timely cybersecurity risk disclosures for publicly traded companies. Several lessons emerge from this incident:

  1. Transparency is Key: Companies must be upfront about material cybersecurity incidents, especially when they affect critical business operations or customer data. Delayed or inaccurate disclosures can have severe consequences for investor trust and regulatory compliance.
  2. Tailored Risk Disclosures: Framing cybersecurity risks in hypothetical terms or generic language does not suffice. Investors need specific, accurate information about the real-world impact of breaches, particularly when a company knows it has been directly affected.
  3. Corporate Responsibility: Cybersecurity is no longer just an IT concern—it is a material risk that can affect a company’s financial performance, reputation, and legal standing. Boards of directors and executives must treat cybersecurity as a critical component of corporate governance.

The Role of the SEC in Enforcing Cybersecurity Standards

The SEC has increasingly focused on cybersecurity risk disclosure in recent years. With this case, the SEC sent a clear message: companies cannot downplay or obscure their exposure to cyber risks, especially when those risks have already materialized. The fines issued in this case serve as a reminder that the SEC will hold companies accountable for misleading disclosures that could harm investors.

As cybersecurity threats continue to evolve, the SEC is likely to impose stricter guidelines on how companies must report breaches and other material cyber incidents.


The SolarWinds attack was a wake-up call for organizations worldwide about the dangers of supply chain attacks and the need for comprehensive cybersecurity defenses. For Unisys, Check Point, Mimecast, and Avaya, the SEC’s fines were a stark reminder of the importance of transparency and accountability in the face of cybersecurity risks.

Moving forward, companies must prioritize accurate, timely disclosure of material cyber incidents to maintain investor trust, comply with regulatory requirements, and protect their reputation in an increasingly digital and interconnected world. Failure to do so can result in not only financial penalties but long-lasting reputational harm.


Comprehensive Case Study: The SolarWinds Cyber Breach

Introduction

The SolarWinds cyber breach, disclosed in December 2020, stands as one of the most significant and sophisticated cybersecurity incidents in recent history. This supply chain attack not only compromised a vast array of organizations, including U.S. government agencies and major corporations, but also underscored the critical vulnerabilities inherent in software supply chains. The breach led to extensive investigations and has had lasting implications on cybersecurity practices and policies.

Background on SolarWinds

SolarWinds, headquartered in Austin, Texas, is a prominent provider of IT management and monitoring software. Its flagship product, Orion, is widely used by organizations to oversee their IT infrastructures. The company's clientele includes numerous federal agencies and Fortune 500 companies, highlighting its significant presence in both public and private sectors.

Discovery of the Breach

In December 2020, cybersecurity firm FireEye discovered that its internal systems had been compromised. Further investigation revealed that the breach originated from a malicious update to SolarWinds' Orion software. This update contained a backdoor, later identified as the SUNBURST malware, which allowed unauthorized access to FireEye's network. Subsequent analyses determined that approximately 18,000 organizations had downloaded the compromised Orion updates, potentially exposing them to similar unauthorized access.

Technical Details of the Attack

The attackers, believed to be associated with the Russian intelligence group APT29 (also known as Cozy Bear), executed a sophisticated supply chain attack by infiltrating SolarWinds' software development process. They introduced malicious code into the Orion software updates, which were then digitally signed and distributed to customers through regular update channels. This method ensured widespread distribution while evading immediate detection.

Once the compromised updates were installed, the SUNBURST backdoor activated, enabling the attackers to communicate with the infected systems and exfiltrate data. The malware was designed to be stealthy, using multiple techniques to evade detection and obscure its activity.

Impact on Victims

The breach had far-reaching consequences, affecting a diverse range of organizations globally. Notable victims included U.S. government agencies such as the Treasury and Commerce Departments, as well as private sector giants like Microsoft. The attackers accessed sensitive data and networks, leading to concerns about national security and corporate espionage.

The financial impact was substantial. Companies affected by the breach faced significant costs associated with incident response, system remediation, and legal fees. For instance, SolarWinds disclosed that it had paid $3.5 million to address the breach through December 31, 2020, covering investigation and remediation efforts, legal and professional costs, and consulting services.

The breach prompted numerous investigations by federal agencies, including the SEC, the Department of Justice, and state attorneys general. These investigations focused on the circumstances surrounding the breach, the adequacy of corporate cybersecurity practices, and the transparency of disclosures to investors and the public.

CyberScoop

In October 2023, the SEC charged SolarWinds and its Chief Information Security Officer (CISO) with making material misstatements regarding the company's cybersecurity practices and for failing to have reasonable internal controls to safeguard its assets. The SEC alleged that SolarWinds and its CISO ignored repeated red flags about cyber risks, which were well known throughout the company.

Securities and Exchange Commission

Furthermore, in October 2024, the SEC fined four technology companies—Unisys, Avaya Holdings, Check Point Software Technologies, and Mimecast—a total of $7 million for providing misleading disclosures related to their involvement in the SolarWinds breach. The SEC determined that these companies downplayed their exposure to the breach, depriving investors of accurate information regarding the incidents' true scope.
