Main Page. WifiInfoView v2. Wifi Collector - Collect wireless networks information and their location on Android device. NK2 of Microsoft Outlook. When you select a wireless network in the upper pane of this tool, the lower pane displays the Wi-Fi information elements received from this device, in hexadecimal format. WifiInfoView also has a summary mode, which displays a summary of all detected wireless networks, grouped by channel number, company that manufactured the router, PHY type, or the maximum speed.

Both bit and x64 systems are supported. If you don't have a compatible wireless adapter and driver, "cannot find wireless adapter" error will be displayed. In order to watch 5GHz wireless networks, you have to use a wireless network adapter that supports 5 GHz channels. Download links are on the bottom of this page Versions History Version 2. Version 2. Updated the internal MAC addresses file. The description specified in this list will be displayed under the 'Description' column. The 'PHY Type' now displays multiple phy types e. Added 'Show only networks with detection count higher than Version 1.

Added 'Channels Range' column, which shows the actual range of channels that the wireless network uses according to the channel width. To sort the first column you should not hold down the Shift key. The 'Cipher' column now displays more accurate information. Each time it receives this message, it will reinstall the same encryption key, and thereby reset the incremental transmit packet number nonce and receive replay counter used by the encryption protocol.

We show that an attacker can force these nonce resets by collecting and replaying retransmissions of message 3 of the 4-way handshake. By forcing nonce reuse in this manner, the encryption protocol can be attacked, e. In our opinion, the most widespread and practically impactful attack is the key reinstallation attack against the 4-way handshake. We base this judgement on two observations. First, during our own research we found that most clients were affected by it. Second, adversaries can use this attack to decrypt packets sent by clients, allowing them to intercept sensitive information such as passwords or cookies.

Decryption of packets is possible because a key reinstallation attack causes the transmit nonces sometimes also called packet numbers or initialization vectors to be reset to their initial value. As a result, the same encryption key is used with nonce values that have already been used in the past. In turn, this causes all encryption protocols of WPA2 to reuse keystream when encrypting packets.

In case a message that reuses keystream has known content, it becomes trivial to derive the used keystream. This keystream can then be used to decrypt messages with the same nonce. When there is no known content, it is harder to decrypt packets, although still possible in several cases e. English text can still be decrypted.

In practice, finding packets with known content is not a problem, so it should be assumed that any packet can be decrypted. As a result, even though WPA2 is used, the adversary can now perform one of the most common attacks against open Wi-Fi networks: injecting malicious data into unencrypted HTTP connections.

For example, an attacker can abuse this to inject ransomware or malware into websites that the victim is visiting. Against these encryption protocols, nonce reuse enables an adversary to not only decrypt, but also to forge and inject packets. Moreover, because GCMP uses the same authentication key in both communication directions, and this key can be recovered if nonces are reused, it is especially affected.

Note that support for GCMP is currently being rolled out under the name Wireless Gigabit WiGig , and is expected to be adopted at a high rate over the next few years. The direction in which packets can be decrypted and possibly forged depends on the handshake being attacked. Simplified, when attacking the 4-way handshake, we can decrypt and forge packets sent by the client. Finally, most of our attacks also allow the replay of unicast, broadcast, and multicast frames. For further details, see Section 6 of our research paper. Note that our attacks do not recover the password of the Wi-Fi network.

They also do not recover any parts of the fresh encryption key that is negotiated during the 4-way handshake. Our attack is especially catastrophic against version 2. Here, the client will install an all-zero encryption key instead of reinstalling the real key. This vulnerability appears to be caused by a remark in the Wi-Fi standard that suggests to clear the encryption key from memory once it has been installed for the first time. When the client now receives a retransmitted message 3 of the 4-way handshake, it will reinstall the now-cleared encryption key, effectively installing an all-zero key.

This makes it trivial to intercept and manipulate traffic sent by these Linux and Android devices.

The following Common Vulnerabilities and Exposures CVE identifiers were assigned to track which products are affected by specific instantiations of our key reinstallation attack:. Note that each CVE identifier represents a specific instantiation of a key reinstallation attack. Although this paper is made public now, it was already submitted for review on 19 May After this, only minor changes were made. As a result, the findings in the paper are already several months old. In the meantime, we have found easier techniques to carry out our key reinstallation attack against the 4-way handshake.

With our novel attack technique, it is now trivial to exploit implementations that only accept encrypted retransmissions of message 3 of the 4-way handshake. This was discovered by John A. Van Boxtel. As a result, all Android versions higher than 6. The new attack works by injecting a forged message 1, with the same ANonce as used in the original message 1, before forwarding the retransmitted message 3 to the victim.

Please cite our research paper and not this website or cite both. You can use the following example citation or bibtex entry:. Mathy Vanhoef and Frank Piessens. We have made scripts to detect whether an implementation of the 4-way handshake, group key handshake, or Fast BSS Transition FT handshake is vulnerable to key reinstallation attacks. These scripts are available on github , and contain detailed instructions on how to use them. We also made a proof-of-concept script that exploits the all-zero key re installation present in certain Android and Linux devices.

This script is the one that we used in the demonstration video. It will be released once everyone has had a reasonable chance to update their devices and we have had a chance to prepare the code repository for release. We remark that the reliability of our proof-of-concept script may depend on how close the victim is to the real network. If the victim is very close to the real network, the script may fail because the victim will always directly communicate with the real network, even if the victim is forced onto a different Wi-Fi channel than this network.

Yes there is. And a big thank you goes to Darlee Urbiztondo for conceptualizing and designing the logo! No, luckily implementations can be patched in a backwards-compatible manner. This means a patched client can still communicate with an unpatched access point AP , and vice versa. In other words, a patched client or access point sends exactly the same handshake messages as before, and at exactly the same moment in time.

However, the security updates will assure a key is only installed once, preventing our attack. So again, update all your devices once security updates are available. Finally, although an unpatched client can still connect to a patched AP, and vice versa, both the client and AP must be patched to defend against all attacks!

Changing the password of your Wi-Fi network does not prevent or mitigate the attack. So you do not have to update the password of your Wi-Fi network. Instead, you should make sure all your devices are updated, and you should also update the firmware of your router.

Nevertheless, after updating both your client devices and your router, it's never a bad idea to change the Wi-Fi password. Yes, that network configuration is also vulnerable. So everyone should update their devices to prevent the attack! I use the word "we" because that's what I'm used to writing in papers.

In practice, all the work is done by me, with me being Mathy Vanhoef. My awesome supervisor is added under an honorary authorship to the research paper for his excellent general guidance. But all the real work was done on my own. There are many Wi-Fi supported devices with the program, and various chipsets, including Atheros, Ralink and many others. The program is not the simplest to use. While it does offer a compact interface, there is no help guide and you need to be an advanced user to understand what you are doing. If you have never worked with security audit tools in the past, you may find Beini to be a bit confusing.

Advanced users have found this program to be helpful.

If you have ever wondered how secure your Wi-Fi connections are, this program will tell you what you need to know in a short period of time.
