Brazilian Citizen Charged in U.S. for Cyber Extortion Scheme

A Brazilian citizen has been indicted in the United States for allegedly engaging in cyber extortion by threatening to release stolen data from a company's network. The charges stem from a March 2020 breach, during which confidential information was stolen, and demands for payment were made in exchange for not disseminating the data.

Details of the Case

Junior Barros De Oliveira, 29, of Curitiba, Brazil, faces multiple charges, including four counts of extortionate threats involving information obtained from protected computers and four counts of threatening communications. The U.S. Department of Justice (DoJ) unsealed the indictment earlier this week, revealing the details of the case.

The Cyber Breach

The victim in this case is a Brazilian subsidiary of a New Jersey-based company. De Oliveira is alleged to have hacked into the company’s network, gaining unauthorized access to sensitive data. Over the course of at least three breaches, he stole confidential information pertaining to approximately 300,000 customers.

Extortion Demands

According to the indictment, De Oliveira contacted the company's chief executive officer (CEO) in September 2020 using an alias. In the email, he demanded a payment of 300 bitcoin, which was valued at approximately $3.2 million at the time. He threatened to sell the stolen data if the payment was not made.

In October 2020, the defendant escalated his demands by forwarding the original email to the CEO and another executive from the Brazilian subsidiary. In a follow-up message to a company representative, De Oliveira presented himself as willing to assist in resolving the security flaw, but only for a "consulting fee" of 75 bitcoin (valued at $800,000 at the time). The email included detailed instructions for transferring the payment to a Bitcoin wallet.

Legal Implications

De Oliveira faces significant legal consequences for his alleged actions:

• Extortionate Threats: Each of the four counts carries a maximum prison sentence of five years and a fine of up to $250,000 or twice the financial gain or loss resulting from the crime.

• Threatening Communications: Each count carries a maximum prison term of two years and similar financial penalties.

If convicted on all counts, De Oliveira could face substantial prison time and financial penalties.

The Bigger Picture: Cyber Extortion and Ransomware

This case highlights the growing trend of cyber extortion, where hackers exploit stolen data to coerce victims into making payments. Cybercriminals often target companies with sensitive customer information, threatening to release or sell the data if their demands are not met.

The Role of Bitcoin in Cybercrime

Bitcoin and other cryptocurrencies have become a common tool for cybercriminals due to their perceived anonymity and ease of transfer across borders. Demands for payment in cryptocurrency make it harder for authorities to track transactions and identify perpetrators.

Protecting Against Cyber Threats

This incident underscores the importance of robust cybersecurity measures to prevent breaches and mitigate the impact of cyber extortion. Organizations can take the following steps to safeguard their networks:

1. Implement Strong Access Controls: Use multi-factor authentication and enforce strict access policies to minimize unauthorized entry.

2. Encrypt Sensitive Data: Encrypt customer and company data to make it less useful to attackers if stolen.

3. Regularly Update Systems: Ensure all software and hardware are updated to address known vulnerabilities.

4. Employee Training: Educate employees about phishing and other social engineering tactics that could lead to breaches.

5. Incident Response Plan: Have a well-defined response plan to quickly address and contain security incidents.

Conclusion

The case against Junior Barros De Oliveira serves as a stark reminder of the risks posed by cyber extortion. With personal and financial data becoming increasingly valuable, organizations must remain vigilant and proactive in protecting their systems. Meanwhile, international cooperation in law enforcement is crucial for holding cybercriminals accountable, as demonstrated by the ongoing efforts of the DoJ to combat cybercrime on a global scale.
