Attackers typically flood the network with excessive traffic, causing legitimate users to experience service interruptions. #### Man-in-the-Middle (MitM) Attacks In a MitM attack, the attacker intercepts and potentially alters the communication between two parties without their knowledge. This can lead to data theft or unauthorized data manipulation. #### Eavesdropping Eavesdropping involves unauthorized interception of voice, data, or messaging services. Attackers can capture confidential information or conversations without the user's consent. #### SIM Card Cloning SIM card cloning allows an attacker to create a duplicate of a victim's SIM card. This enables the attacker to make calls, send messages, and access the victim's data plan, leading to potential financial loss. #### SMS Phishing (Smishing) Smishing involves sending fraudulent SMS messages to deceive users into revealing personal information, such as login credentials or financial information, which can then be used for malicious purposes. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
