1 man-in-the-middle attack OverviewMan-in-the-middle attack (mitm) is a long-standing network intrusion method, and still has a wide range of development space today, such as SMB session hijacking, DNS spoofing, and other attacks are typical mitm attacks. In short, the so-called mitm attack intercepts norm

After opening ettercap, select sniff ---- uniied-sniffing and then select NIC: Then hosts --- scan for hosts --- host
First, this vulnerability carries some interesting attack methods. Of course, it has a serious impact on those unfortunately recruited. However, to enable attackers to exploit this vulnerability, hackers need to use other vulnerabilities for MITM access. Of course, if you have local subnet access or hackers use DNS spoofing, you can easily perform MITM access. However, these requirements have increased the

If you go a public caffee shop, they has free wifi. How could do sure your infomration cannot being read by a second person?Well, in HTTP1.1, you cannot. With HTTPS, it'll encpty your data and only the server is talking to can decode your data.And how is thought you is talking to the real server but actually you is not. MITM would redirect you to their server and decode the message and read, then send to the real server. One thing in HTTPS to prevent
The current version of SSLv3 is version 3.1, also known as TLS. It provides a mechanism for secure data transmission over the network. It is said to meet all security needs, such as your bank account management.

In this article, we will discuss the theory and demonstration of session hijacking and discuss related detection and defense techniques.
In the previous two articles, we discussed ARP cache poisoning and DNS Spoofing respectively. From

This confirms that GC is located in an asn, and a previously gfw man-in-the-middle attack is located in the same place.
The investigator published some PCAP files about GC and GFW.

recognized by CISCO and Juniper.
3. The focus of this study is not "whether it is a router problem 」. The conclusion is that, first, it is determined that there is none-blind IP spoofing, rather than the DNS attack, and there is no ARP attack. This is different from others' opinions. Second, from the perspective of the incoming packets and the attack volume content (insert iframe), the attacker cannot modify the original packet, you cannot avoid Original or hidden packets, or avoid real packets
Back in the lab, I started my research. For my further research, I ran MSSQL Server 2012 Express on Windows Server 2014 R2. The client is a Windows 10 system and runs MSSQL Management Studio 2014. My attacker is a newly installed Kali 2.0. All machines are in the same subnet to simulate attacks on the Intranet. This environment is almost the same as my client environment.
This type of attack is MITM, and Anitia
ARP spoofing and man-in-the-middle attacksPreface:
In the previous WPA/WAP2wifi password cracking note, we talked about how to detect nearby open APs and crack the access, so what can we do when we enter someone else's lan? In other words, what will happen if someone else enters our internal network? This article briefly introduces the principles of ARP and MITM, and hijack the traffic of the target host in the actual environment. Exposed the common p

The first process of pairing is the exchange of pairing information, which is used to determine the authentication method, and whether or not to assign a key and which keys to assign later.
The information exchanged includes:
Both ends of the device input and output capabilities such as: whether there is a display, keyboard and so on.

TK is generated to generate another STK to encrypt the link and then distribute LTK, IRK, and CSRK. (If the pairing information exchange is not binding, the key distribution will not be needed in the future)

The first process of pairing is the exchange of pairing information, which is used to determine the authentication method, as well as whether to allocate and which keys will be allocated in the future.
