makeivs-ng

Create Initial Vector Sequences for encryption

-s
    Specifies the size of the IVs to create, in bytes. For WEP, this is typically 3 bytes.

-b
    Sets the MAC address of the Access Point (BSSID) for which to generate IVs.

-w
    Provides a known WEP key (in hex or ASCII) to be used when generating IVs, useful for testing or specific attacks.

-c
    Specifies the total number of IVs to generate.

-d
    Sets a delay in microseconds between the generation of each IV.

-e
    Defines the ESSID (network name) for which the IVs should be generated.

--help
    Displays the help message and exits.

DESCRIPTION

makeivs-ng is a utility within the Aircrack-ng suite designed to generate fake Initialization Vectors (IVs) for WEP key cracking. It allows users to create a specified number of IVs with custom characteristics, such as the BSSID of an Access Point, a known WEP key, or a particular ESSID. These generated IVs can then be used in conjunction with other tools like aireplay-ng for various injection attacks, such as testing the validity of a known key or conducting sophisticated attacks like the Chopper attack. While WEP is a deprecated and insecure encryption standard, makeivs-ng remains valuable for educational purposes, security auditing of legacy networks, or forensic analysis.

CAVEATS

makeivs-ng is primarily useful for attacking WEP encrypted networks, which are considered highly insecure and deprecated. Its use on networks without explicit permission is illegal and unethical. Ensure you have proper authorization before using this tool.

PREREQUISITES

To use makeivs-ng, a wireless adapter capable of monitor mode and packet injection is required. The specified interface must be put into monitor mode using tools like airmon-ng prior to running makeivs-ng.

OUTPUT

makeivs-ng typically outputs the generated IVs to standard output, which can then be piped to other tools or saved to a file for later use. The output format depends on the specific use case and how it's integrated into a larger attack or testing script.

HISTORY

makeivs-ng is an integral part of the Aircrack-ng suite, a network security software suite originally designed for 802.11 WEP and WPA/WPA2-PSK key cracking. Developed to address the vulnerabilities in wireless encryption protocols, tools like makeivs-ng became crucial for demonstrating and exploiting weaknesses in WEP. Although WEP has largely been replaced by more robust security protocols, the development of makeivs-ng contributed significantly to the understanding and auditing of wireless network security during its prevalence.
