16. An accounting clerk sent money to an attacker's bank account after receiving fraudulent instructions over the phone to use a new account. Which of the following would most likely prevent this activity in the future?
Answer: D
Updating processes for sending wire transfers would most likely prevent this activity in the future.
Revising the procedures for wire transfers can ensure that proper verification methods are in place before any funds are sent, thereby mitigating the risk of falling victim to fraudulent instructions.
A) Standardizing security incident reporting
While standardizing security incident reporting is important for tracking and managing future threats, it does not directly address the specific issue of verifying wire transfer instructions. This approach focuses on post-incident analysis rather than preventing fraudulent transactions.
B) Executing regular phishing campaigns
Conducting phishing campaigns may raise awareness among employees regarding potential email scams, but it does not directly impact the verification process for wire transfers conducted over the phone. Thus, it is unlikely to prevent this particular type of fraud.
C) Implementing insider threat detection measures
Insider threat detection measures are designed to identify risks posed by individuals within an organization. This approach does not address the external threat of fraudsters impersonating legitimate contacts to manipulate employees into making unauthorized transfers.
D) Updating processes for sending wire transfers
Revising the processes for sending wire transfers is the most effective solution to prevent fraudulent activities like this. By establishing strict verification protocols, such as requiring multiple confirmations or alternative verification methods, organizations can significantly reduce the risk of unauthorized transactions resulting from fraudulent phone calls.
Conclusion
Updating wire transfer processes directly targets the vulnerabilities that allowed the fraudulent transaction to occur, making it the most effective preventive measure. In contrast, the other options focus on broader security strategies or different types of threats, which do not specifically address the issue at hand. Therefore, option D stands out as the definitive solution to mitigate the risk of similar incidents in the future.
