I've seen a couple of explanations, but I don't understand it completely. Most explanations go something like this. Alice requests Bob for a key. Bob sends the key back. Eve(attacker) receives bob's key stores it, then sends Alice a different key. when Alice sends bob things, eve can decrypt it since Alice is using Eve's key. Eve then re-encrypts it using bobs key then sends it back to bob. The part I don't understand is why Eve supplies Alice with a different key. Alice already knows bob's key, so couldn't she already intercept Alice's messages and read them?
Hi,
So right now we have an external sender who's trying to send an email to one of our employees. But for some reason our employee cannot receive the emails. So I requested for a test email to be sent to me, and the employee CC'd (even email sent to him directly is not received). I was able to receive the email, but the CC'd employee was not able to. I've checked our mail logs in exchange and found no logs whatsoever, except for the email I received. I even consulted the team managing our postfix mail gateway and they said there was no smtp log except mine.
I was wondering if this could be some sort of a man in the middle attack, wherein our employees email address is being spoofed by another person? Also, would it be possible for me to trace what happened to the other CC'd employee through the internet headers of the email I receive?
I appreciate the responses in advance, thanks!
I just found out that I’m a victim of a “man in the middle attack”. I’ve been trying to find unusual activity happening and I did. I was recently hacked and my accounts were compromised, including emails. I thought it was only my information on the computer that was hacked. I later found on a new email I created that a hacker was searching stuff in my activity. I then left that email alone and made a new one. I then received emails from a fake email from Facebook in German language on my new email saying “trying to login into your account?” or something like that. I never used Facebook on the email. Everyone connected to the network is also receiving these phishing emails and are also being redirected to phishing sites. I formatted the pc that was infected and flashed the bios, but it seems to be happening still. So I’m sure it’s a man in the middle attack. I’ve factory reset the router and reset the firmware twice, still there. We contacted cogeco about this and they said our router is fine. But this activity keeps happening. When I go onto websites the language sometime is defaulted in German but the language in my google settings is English. I don’t know how to remove this “man in the middle attack” and would like help to remove this, I’m very worried because I don’t want my whole family to get their accounts compromised and fall for any phishing sites and emails. I’ve been trying to find out what to do by can’t find anything to fix it. Any help would be greatly appreciated.
Today, SySS published a new proof-of-concept video about an old security issue - poorly secured RDP connections.
You can find the video demonstrating successful MitM attacks against RDP connections using the software tool Seth on YouTube: https://www.youtube.com/watch?v=JvvxTNrKV-s

Hey guys!
So whenever I see a MITM demonstration or video, people always say that you can create host websites that look exactly like other websites to get the passwords. What I'm curious about, is why don't you just request the original website with https, and then serve it back to the user over http (or maybe spoof a https cert).
Then when a user enters data (like username / password) and sends a request, you simply save the request locally and also forward it to the original website, and then return the response to the user.
Hopefully that makes sense. It seems like if a user had full access to the original website then you could get a lot more information than just their username/password.
Is it not possible? I feel like people would have already done something like this if it was possible.
Thanks a ton!
So I'm trying send some btc to an exchange. I'd read about the possibility of a man-in-the-middle attack, so I was glad to see that Ledger now requires you to check the receiving address on the device itself.
The first confirmation shows the correct amount and correct receiving address. But the second confirmation suddenly shows a different amount and a different receiving address.
So I obviously cancelled and tried again, but the same thing happens. The new amount was considerably smaller than the first in this case.
I decided to try again, this time sending a smaller amount. Again, the first confirmation shows the right address and the right amount, but the second confirmation shows a different address (but the same one as the previous two times) and the amount had changed to a figure 13 times larger.
What's going on here? Is it a man-in-the-middle attack? If so, how could it work if only 1 of the 2 transaction confirmations seemed to be affected?
