NioCorp Developments Reports Cyberattack Resulting in $500,000 Financial Loss

US-based mining company NioCorp Developments has reported a cybersecurity breach that resulted in a financial loss of approximately $500,000. In a regulatory filing with the U.S. Securities and Exchange Commission (SEC) on Wednesday, the company disclosed that the attack, which was identified on February 14, 2025, involved unauthorized access to its email systems.

The attackers leveraged the compromised system in what appears to be a business email compromise (BEC) attack, a common and highly effective cybercrime technique that exploits trust in email communications to misdirect payments.

Nature of the Attack

Based on NioCorp’s preliminary findings, the attackers infiltrated the company's email system and used it to send fraudulent payment requests. This resulted in misdirected vendor payments totaling around $500,000.

BEC attacks typically involve spoofed or hacked email accounts used to trick employees into approving wire transfers to cybercriminals. In this case, it appears that the attackers impersonated vendors or altered legitimate transactions to reroute funds to fraudulent bank accounts.

Company's Response and Investigation

NioCorp has taken immediate action following the discovery of the breach, including:

• Notifying financial institutions in an effort to freeze or recover the misdirected funds.

• Alerting law enforcement authorities to investigate the attack and identify the perpetrators.

• Conducting an internal investigation to assess the full impact of the breach.

While the company believes the incident was limited to the misdirected vendor payments, it has stated that the full scope and impact of the breach are still under investigation.

Business Email Compromise: A Growing Threat

BEC attacks are one of the costliest forms of cybercrime, often resulting in multi-million dollar losses for businesses. The FBI’s Internet Crime Report revealed that:

• BEC attacks caused $2.9 billion in losses in 2023 alone.

• Over the past ten years (2013-2023), businesses worldwide have lost an estimated $55 billion due to these scams.

Unlike traditional cyberattacks that rely on malware, BEC attacks exploit human trust, often bypassing security defenses. Attackers frequently study internal communications, impersonate executives, vendors, or employees, and craft highly convincing emails to deceive financial departments into transferring funds.

Mitigation Strategies Against BEC Attacks

To prevent BEC attacks, companies should implement strong email security measures and educate employees about phishing tactics. Best practices include:

• Multi-Factor Authentication (MFA): Requiring additional verification for email logins to prevent unauthorized access.

• Strict Payment Verification Processes: Implementing multi-step approval procedures for wire transfers and payment changes.

• Email Filtering & AI-Powered Detection: Using email security tools to identify and block phishing attempts.

• Employee Training: Regular cybersecurity awareness programs to help staff recognize suspicious emails and social engineering tactics.

• Monitoring for Anomalies: Implementing systems to flag unusual payment requests or changes to vendor details.

Conclusion

The NioCorp cyberattack serves as another stark reminder of the financial risks posed by business email compromise scams. As companies continue to rely on digital communication for financial transactions, cybercriminals are becoming more sophisticated in their techniques. Organizations must take proactive security measures to prevent falling victim to similar schemes and ensure robust cybersecurity protocols are in place.

The investigation into NioCorp's breach remains ongoing, and it is yet to be determined whether the company will be able to recover the misdirected funds.
