Explanation:

• For the first question: Reusing passwords across multiple sites means if one site's security is compromised (breached), attackers can use that password to access other accounts since it's the same.
• For the second question: Being cautious about revealing services or software used at work on social media is a good practice as it can prevent potential security risks or misuse of information.
• For the third question: MFA bombing/fatigue refers to attackers sending repeated MFA requests. Users, annoyed by the constant requests, might mistakenly approve one, giving attackers access.

Answer:

• First question: If one site is breached, all accounts are vulnerable.
• Second question: Be cautious about revealing which services or software you use.
• Third question: Attackers repeatedly sending MFA requests hoping users approve out of annoyance.
