What does passive sniffing allow attackers to do in a network using hubs?

• A. Manipulate packet headers
• B. Capture all traffic passing through the network
• C. Access secured files remotely
• D. Perform DDoS attacks

Answer: (B)

Passive sniffing is a technique used by attackers to monitor and capture data packets traveling through a network. This method is particularly effective in networks that utilize hubs, as hubs broadcast incoming packets to all connected devices rather than directing traffic to specific endpoints. When an attacker employs passive sniffing in a hub-based network, they can intercept and capture all traffic that passes through the hub. This means that any unencrypted data, including sensitive information such as usernames, passwords, and other plaintext communications, can be collected and analyzed without altering the data or affecting the network’s operation. The ability to capture all traffic is what makes passive sniffing a powerful tool for attackers, providing them with valuable insights into network activity without being detected. In contrast, manipulating packet headers or accessing secured files typically requires active involvement or different tactics that go beyond the scope of passive sniffing. Similarly, performing DDoS (Distributed Denial-of-Service) attacks involves overwhelming a target system, which is unrelated to the capabilities of passive sniffing.
