Which tool is commonly used to obtain password hashes when sniffing mode is used by an attacker?

• A. SID Of Hillary Network Account
• B. Network Shares That Hillary Has Permissions
• C. Username And Password Hash
• D. SAM File From Hillary Computer

Answer: (C)

When an attacker uses sniffing mode, they are passively listening to network traffic to capture credentials as they are transmitted during authentication. On many networks, especially Windows-based ones using NTLM, the credentials aren’t sent as plaintext but as a hashed form along with the username. So what the attacker typically harvests in this scenario is the username together with the password hash. This captured data can then be used for offline cracking or pass-the-hash attacks, making the combination of a username and its corresponding hash the key item obtained through sniffing. The other options don’t fit this scenario as well. A SAM file is stored on a local machine and requires access to that host to retrieve the hashes, not something captured through network sniffing. Network shares that a user has permissions refer to access rights, not the actual credential data transmitted during authentication. A SID identifies an account but isn’t the credential data itself. So the captured credential data during sniffing is best described as the username and password hash.
