Study Notes
Wireless Attacks Overview
- Users can be tricked into connecting to the wrong access point (AP), compromising their network security.
- Such a malicious tactic involves not only the redirection of network traffic but also the manipulation of the data packets that users send and receive over the internet. As a result, attackers can capture sensitive information, such as usernames, passwords, and credit card details. The loss of confidentiality in this context encompasses both personal and organizational data, placing users at increased risk. Furthermore, this vulnerability can serve as an entry point for additional attacks, allowing perpetrators to impersonate legitimate users and execute various forms of cyber exploitation.
Network Design
- Larger networks often use an Extended Service Set Identifier (ESSID) to support multiple APs.
- APs are strategically positioned for optimal coverage that avoids interfering with adjacent areas.
Rogue Access Points
- An unauthorized AP can be introduced into the network, leading to potential breaches.
- Example: A technician plugged in a rogue AP with good intentions, inadvertently providing unauthorized access to a secure network.
Evil Twin Attack
- An attacker can create an evil twin AP that mimics a legitimate ESSID to deceive users into connecting.
- The attacker uses tools to identify the network configuration and assigns IP addresses similar to the legitimate network.
DHCP Spoofing
- The attacker assigns an IP like 10.1.10.105, making it the default gateway and DNS server.
- Legitimate traffic is funneled through the attacker's machine under the guise of normal operation.
Deauthentication Attacks
- Attackers can send deauthentication messages to disconnect clients from the legitimate AP.
- This tactic forces clients to reconnect, often to the attacker's evil twin network.
Identification Process
- Tools like net spot are employed to scan for available wireless networks.
- Attackers make note of the legitimate network identifiers to replicate them accurately.
Rogue AP Configuration
- Attackers can configure their evil twin using specific SSID settings and security configurations.
- If using a pre-shared key, it is often shared or poorly protected, aiding in the attack.
Impact of Successful Attacks
- Users unknowingly connect to the attacker's network, allowing interception and manipulation of their traffic.
- The attacker's machine can respond to DNS requests with spoofed answers, facilitating further exploitation.
Next Steps
- Future discussions will delve into DHCP and related attacks, highlighting vulnerabilities and mitigation strategies.
