What are two main vulnerabilities associated with VoIP?

The correct identification of the two main vulnerabilities associated with Voice over Internet Protocol (VoIP) being vishing and credential harvesting reflects a solid understanding of the specific threats that can target VoIP systems.

Vishing, or voice phishing, involves attackers using VoIP technology to impersonate legitimate entities to extract sensitive information from individuals. Typically, this could involve tricking users into providing credentials, banking information, or other personal data over the phone, leveraging the telephonic interface VoIP provides. Given that VoIP enables calls over the internet, it can be easier for attackers to disguise their identity, making vishing a significant risk.

Credential harvesting, closely related to vishing, refers to the direct attempts to collect user credentials through deceptive practices. This can occur through various means, including phishing emails or malicious VoIP calls that prompt users to enter their credentials on an illegitimate platform. Both of these vulnerabilities exploit reliance on trust in voice communications, which can erode security.

Choosing this option showcases an understanding of the nuanced ways that VoIP systems can be exploited in the realm of cybersecurity. It highlights the need for users to remain vigilant about the identity of callers and to safeguard sensitive information against deceptive practices specifically targeting voice communication technology.
