Digital Event Horizon
A new vulnerability known as AirSnitch has been discovered, allowing attackers to bypass traditional security measures and inject data into remote GRE tunnels. This attack can be used to intercept sensitive data and perform more advanced attacks, making it a serious threat to organizations relying on Wi-Fi networks.
The AirSnitch attack allows an attacker to intercept all link-layer traffic, giving them access to sensitive data.Up to 20% of pages loaded on Windows and Linux machines are not encrypted, making them vulnerable to interception.The attack can bypass traditional security measures, including network access control lists and GRE tunnels.The AirSnitch attack can intercept domain look-up traffic and use DNS cache poisoning to corrupt tables stored by the target's operating system.Experts are urging users to exercise measured caution when using public Wi-Fi networks and consider using a trustworthy VPN or tethering their device to a secure connection.
The world of cybersecurity is constantly evolving, and a recent discovery has shed light on a new vulnerability that threatens the security of Wi-Fi networks. The AirSnitch attack, as it has come to be known, allows an attacker to intercept all link-layer traffic, giving them access to sensitive data and the ability to perform more advanced attacks.
According to recent estimates, up to 20% of pages loaded on Windows and Linux machines are not encrypted, making them vulnerable to interception. This means that even if a user is using HTTPS, they can still be affected by the AirSnitch attack. The attacker can view and modify all traffic in the clear, stealing authentication cookies, passwords, payment card details, and other sensitive data.
The most dire consequence of this vulnerability occurs when an Internet connection isn't encrypted. In these cases, the attacker can view and modify all traffic in the clear, allowing them to steal sensitive information. Since many company intranets are sent in plaintext, traffic from them can also be intercepted.
Even when HTTPS is in place, an attacker can still intercept domain look-up traffic and use DNS cache poisoning to corrupt tables stored by the target's operating system. The AirSnitch MitM attack puts the attacker in the position to wage attacks against vulnerabilities that may not be patched. Attackers can also see the external IP addresses hosting webpages being visited and often correlate them with the precise URL.
This vulnerability has been dubbed "AirSnitch" due to its ability to bypass network access control lists and inject data into remote GRE tunnels, allowing it to bypass traditional security measures. The attack relies on the attacker spoofing the victim's MAC address on a different NIC, causing the internal switch to mistakenly associate the victim's address with the attacker's port/BSSID.
Once the attacker has successfully spoofed the victim's MAC address, they can intercept all downlink traffic intended for the target. They then use this information to restore the original MAC > port mapping, allowing them to redirect the intercepted frames back to the target. This completes the first half of the MitM attack, giving the attacker full control over the victim's network.
The AirSnitch attack has significant implications for organizations that rely on Wi-Fi networks. It highlights the need for improved security measures to protect against such vulnerabilities. Experts are urging users to exercise measured caution when using public Wi-Fi networks and to consider using a trustworthy VPN or tethering their device to a secure connection.
In conclusion, the AirSnitch attack is a serious vulnerability that can be used to intercept sensitive data and perform more advanced attacks. It highlights the need for improved security measures to protect against such threats, particularly in organizations that rely on Wi-Fi networks.
