In the category of social action that is defined by VERIS, which three communication channels can be classified under the vector attribute? (Choose three.)

In the category of social actions as defined by VERIS (Vocabulary for Event Recording and Incident Sharing), which focuses on social engineering techniques, the three communication channels that can be classified under the vector attribute are:

1. Email: This is a common vector for social engineering attacks, such as phishing, where attackers deceive recipients into revealing sensitive information or clicking malicious links.
2. IM (Instant Messaging): Social engineering attacks can also be conducted via instant messaging platforms, where attackers may impersonate trusted contacts to extract information or distribute harmful links.
3. Social Media: Platforms like Facebook, Twitter, LinkedIn, and others are increasingly used for social engineering attacks. Attackers might use fake profiles or hijack existing ones to gain trust and manipulate targets.

FTP, Telnet, VPN, command shell, and remote file injection are more technical vectors typically associated with hacking-related actions rather than social engineering. Social actions in cybersecurity often involve manipulating individuals into breaking normal security procedures, and these are effectively conducted through communication channels like email, IM, and social media.
