Use sslstrip for man-in-the-middle attack (Bypass https)Author: kevin2600 This is the first record of the November! This is a post I posted in anywlan before. Now I want to test it here! If you send an error, please correct it. We all know that man-in-the-middle attacks on the Intranet allow attackers to more effectively intercept passwords and confidential information of Intranet users. Use the EtterCap or ArpSpoof tool in the BackTrack environment.

1. SSL parsingSSL is the short name of Secure Socket layer, the Chinese meaning is Secure sockets layers, developed by Netscape Company, to ensure the security of data transmission on the Internet, so as to make sure it will not be intercepted and bugged during the transmission of the network.The services provided by the SSL protocol are mainly:(1) Authenticate users and servers to ensure that data is sent to the correct customers and servers.(2) Encrypt data to prevent the data from being stole

Future of SSLStrip-HTTPS front-end hijacking (1) 0x00 Preface In the previous article on traffic hijacking, we mentioned a scheme of "HTTPS downgrading"-replacing all the HTTPS hyperlinks on the page with the HTTP Version, allows users to communicate in plain text. If you see this, you may think of a classic man-in-the-middle attack tool, SSLStrip, which can indeed achieve this effect. However, what we hav

In January, I wrote an article named "SSL: Really broken this time", which mentioned that if the certificate issuing Authority uses the MD5 Algorithm for digital signature, the certificate can be forged. Of course, this vulnerability can be easily corrected as long as the Certificate Authority uses SHA-1 instead of the MD5 algorithm. Even so, many people still think that SHA-1 will be followed by MD5 soon. SSLsniff Actually, cracking SHA-1 is only a matter of time. Maybe you still remember Mo

Although tcpdump can dump the data that passes through, but it is not possible to see the contents of encrypted data, HTTPS is a typical example. So how to decrypt the HTTPS packet to read it. This time for you to explain the SSLstrip intercept https example. (Note: Only for offensive drills and safety precautions, prohibited for illegal purposes) 1. Before using, let's look at the help options to determine what parameters are available. Enter "

visit to see the forged SSL certificate information. As can be seen here, the false certificate in the "issued to", "issuer", "Effective Date" and the true certificate (see), the attacker can generate a certificate release certificate to write the same information as the original certificate to confuse the user, but not to confuse the authentication mechanism of the certificate. For ordinary users, be sure to see the browser's warning message, if there is a problem, do not continue to visit.Sec

the Gmail mailbox.Through the above analysis, we can find that the user's judgment on the forgery of certificates is the key to the success of the attack, if the user has a strong security awareness and rich network knowledge, the possibility of being attacked will be greatly reduced. After all, the security tips in the browser are still very eye-catching. I believe that with the increasing popularity of network knowledge, the survival space of such attacks will be squeezed.3.2 sslstripAlthough

, encrypted data is obtained, and the original usage is lost.This is a simple example to introduce the SSL security protocol.Isn't the SSL Security Protocol safe?Cracking? If it was before, it would be hard to say, but now we can clearly tell you that it can be cracked. The following is an excerpt (fromHttp://butian.org/server/780.htmlReporting time 2009.02.22 ):Moxie Marlinspike explained how to use middlemen at the Black Hat security conference on WednesdayAttackTo break SSL layer sessions.

been directly threatened in most cases. An SSL connection is usually initiated through HTTPS, because the user is located to HTTPS through the HTTP 302 response code or they click the connection to locate it to an HTTPS site, such as the login button. That is to say, If attackers attack the communication from a non-secure connection to a secure connection, that is, from HTTP to HTTPS, the actual attack is the "bridge", and the man-in-the-middle attack when the SSL connection has not yet occurre
