A Chronicle of Recent Attacks: A Cause for Concern

Several recent attacks on Vietnamese financial institutions serve as stark reminders of the ever-present threat:

• March 2024: A previously unknown hacking group called Lotus Bane targeted a Vietnamese financial entity, showcasing the emergence of new threats.
• March 2024: VNDirect Securities JSC, a major Vietnamese brokerage firm, was forced to shut down its systems for a week after a ransomware attack. This incident disrupted trading activities and caused customer inconvenience.
• April 2024: Vietnam Oil Corporation (PVOIL) was hit by a ransomware attack, disrupting their electronic invoice system. This attack demonstrates the potential for cyberattacks to cause widespread disruption beyond just financial institutions.

These are just a few examples, and the true number of attacks is likely much higher, as many incidents go unreported.

The Evolving Threat Landscape: A Multifaceted Assault

Cyberattacks on financial institutions encompass a wide range of tactics, each designed to exploit vulnerabilities and achieve financial gain. Here's a closer look at some of the most common threats Vietnam's financial sector faces:

• Malware: Malicious software like Trojans and ransomware remain a significant threat. Trojans like GoldPickaxe, discovered in 2023, target both Android and iPhone users, stealing login information and facial recognition data. Ransomware attacks, where cybercriminals encrypt data and demand a ransom for its release, are a major concern for businesses. A 2024 Kaspersky survey revealed that a staggering 67% of businesses in Southeast Asia, including Vietnam, have been victims of ransomware attacks.
• Phishing Attacks: These social engineering scams attempt to trick individuals into revealing personal information or clicking on malicious links. Phishing emails often impersonate legitimate financial institutions, creating a false sense of security. With Vietnam experiencing a surge in online phishing scams, with over 95% targeting banks and financial institutions according to the Ministry of Information and Communications (MIC), vigilance is crucial.
• Advanced Persistent Threats (APTs): These targeted attacks by sophisticated hacking groups pose a significant threat. A new group called Lotus Bane was discovered targeting a Vietnamese financial entity in March 2024, highlighting the evolving tactics of these cybercriminals.
• Supply Chain Attacks: These attacks target third-party vendors and partners of financial institutions, exploiting weaknesses in their security to gain access to the financial institution's systems.
• Zero-Day Attacks: These exploit previously unknown vulnerabilities in software, making them particularly dangerous as there are no security patches available.

The financial sector is a prime target for cyberattacks due to the vast amount of sensitive data it stores, including customer financial information, account details, and transaction history. A successful attack can result in significant financial losses, reputational damage, and a loss of customer trust.

Vietnam's Response: Bolstering Cyber Defenses

The Vietnamese government is aware of the growing threat posed by cyberattacks and is taking steps to address it. Here are some key initiatives:

• The National Cyber Security Centre (NCSC): Established under the Ministry of Information and Communications (MIC), the NCSC plays a vital role in coordinating national cybersecurity efforts. They work to identify and mitigate cyber threats, block fraudulent websites, and raise awareness about cybersecurity best practices.
• Personal Data Protection Decree (Decree 13): This decree outlines regulations for data privacy and security. While it mandates reporting data breaches within 72 hours, it lacks specific security measures, creating a gap that needs to be addressed.
• Network Information Security Regulations: These regulations establish minimum security standards for information systems, including firewalls, access controls, and incident response procedures.
• Sectoral Regulations: These tailor security requirements to specific industries, such as stricter protocols for online securities trading.

These initiatives represent a positive step towards strengthening Vietnam's cybersecurity posture. However, more needs to be done to effectively combat the evolving threat landscape.

Building a Robust Defense: A Shared Responsibility

In addition to the government’s responses, the responsibility for cybersecurity in Vietnam's financial sector rests on several shoulders:

Financial Institutions:

• Investment in Security Measures: Financial institutions need to invest in robust cybersecurity measures, including:
• Multi-layered security systems: This includes firewalls, intrusion detection and prevention systems (IDS/IPS), data encryption, and vulnerability management programs to identify and patch weaknesses in software.
• Employee Training: Regularly train employees in cybersecurity best practices, including phishing awareness and how to identify and report suspicious activity.
• Incident Response Planning: Develop a comprehensive incident response plan that outlines procedures for detecting, responding to, and recovering from cyberattacks.
• Data Security Controls: Implement data security controls such as access controls, data encryption, and data loss prevention (DLP) to protect sensitive information.

Individuals:

• Be Wary of Phishing Attempts: Don't click on suspicious links or open attachments from unknown senders. Verify the legitimacy of a sender before responding to emails or calls requesting personal information.
• Strong Passwords: Use strong, unique passwords for all online accounts and enable two-factor authentication (2FA) whenever possible.
• Software Updates: Keep your software, including operating systems and applications, updated with the latest security patches.
• Download with Caution: Only download applications from trusted sources and avoid downloading from unknown websites.

Collaboration is Key

Financial institutions and individuals play a crucial role in safeguarding the financial sector, but collaboration is key. The government can facilitate this collaboration by:

• Promoting Information Sharing: Encourage financial institutions to share information about cyber threats and best practices with each other and with the government. This can help to identify and mitigate emerging threats more effectively.
• Public Awareness Campaigns: Launch public awareness campaigns to educate Vietnamese citizens about cybersecurity threats and best practices. This will empower individuals to protect themselves online.
• Regulatory Framework Review: Regularly review and update the legal and regulatory framework for cybersecurity to ensure it remains effective in the face of evolving threats.
• By working together, the government, financial institutions, and individuals can create a more secure financial ecosystem in Vietnam.

The Road Ahead: Constant Vigilance and Continuous Improvement

Cybersecurity is an ongoing battle, and there is no silver bullet. Vietnam's financial sector faces a constantly evolving threat landscape. However, by implementing robust security measures, fostering collaboration, and promoting cyber awareness, Vietnam can build a more resilient financial system capable of withstanding cyberattacks and ensuring a secure financial future for its citizens.

Additional Considerations:

• The role of international cooperation: Cybercrime transcends borders. Vietnam can benefit from collaborating with international partners to share information about cyber threats and best practices.
• The impact on financial inclusion: Cybersecurity concerns should not impede financial inclusion initiatives. Striking a balance between security and accessibility is crucial.
• The rise of Fintech: The growing popularity of Fintech solutions in Vietnam introduces new security challenges. Regulations and security measures need to adapt to this evolving landscape.

In conclusion, Vietnam's financial sector faces a significant challenge in securing its systems against cyberattacks. By acknowledging the evolving threats, implementing robust security measures, fostering collaboration, and promoting cyber awareness, the sector can build a more secure financial future for its organisations and consumers.
