Incident Details:

• An Arup employee in Hong Kong was deceived into joining a video call with individuals they believed to be the Chief Financial Officer and other staff members.
• These individuals were, in reality, deepfake recreations designed to mimic authentic personnel.
• The deception led to the unwitting transfer of $25 million to cybercriminals.

Lessons Learned:

• Employee Vigilance: The employee initially resisted the transfer, adhering to cybersecurity training protocols.
• Threat Actor Creativity: The sophistication of deepfakes presents new challenges in verifying the authenticity of communications.

Quote: Steve highlighted, "This story is a salute to employees doing what they are trained to do in terms of staying vigilant, while at the same time serves as a reminder of the endless creativity of threat actors."

Conclusion: The incident underscores the escalating sophistication of cyber threats and the critical role of continuous employee training and awareness in preventing financial losses.

C. NIST's National Vulnerability Database (NVD) Backlog Issues

Presenter: Rich Stroffolino
Timestamp: [07:58]

Overview: Rich delves into the ongoing challenges faced by NIST's National Vulnerability Database (NVD) in managing and enriching vulnerability data.

Key Points:

• Backlog Problem: Since April, NIST has struggled with significant backlogs in the NVD, hindering the timely updating and enrichment of vulnerability information.
• Efforts to Mitigate: In May, NIST hired a contractor aiming to clear the backlog by the end of September. However, by November, significant progress was made but the backlog persisted.
• Future Concerns: The long-term sustainability of NVD as the definitive source for vulnerability data is in question. Potential solutions, such as forming a consortium with industry and government stakeholders, remain unmaterialized.

Quote: Rich pondered, "Will the idea of the NVD as a single source of vulnerability truth become just a quaint anachronism? It's my big unresolved question going into the new year."

Conclusion: The situation raises concerns about the capacity of critical vulnerability databases to keep pace with the growing complexity and volume of security threats, potentially necessitating structural reforms and collaborative approaches.
