The common form of social engineering attack among the options provided is: "Hoax virus information emails."

Here's a step-by-step explanation:

1. Social engineering attacks are manipulative tactics that trick people into revealing sensitive information. They rely heavily on human interaction and often involve tricking people into breaking normal security procedures.

2. A hoax virus information email is a type of phishing attack, which is a form of social engineering. In this case, the attacker sends an email that appears to be from a reputable source, warning the recipient about a non-existent virus. The email may contain a link or an attachment that, when clicked or opened, can lead to the installation of malware or the theft of personal information.

3. Stealing the key card of an employee and using that to enter a secured building is a physical security breach, not a social engineering attack.

4. Using a sniffer to capture network traffic is a form of network eavesdropping or spying, not a social engineering attack.

5. Distributing false information about your organization's financial status is a form of misinformation or disinformation, which can be part of a broader social engineering campaign, but on its own, it's not a typical form of social engineering attack.
