Can HTTPS be intercepted by ISP?
Encrypted communication, such as HTTPS, FTPS, SFTP, etc., can also be intercepted, but the user will know that this is happening. For example, if a user wants to access https://example.com . An ISP intercepting that traffic would need to have a valid certificate for this website in order to not be detected.
Can ISP decrypt HTTPS traffic?
When a web site does use HTTPS, an ISP cannot see URLs and content in unencrypted form. However, ISPs can still almost always see the domain names that their subscribers visit. DNS queries are almost never encrypted. In fact, DNS queries are almost never encrypted.
Does HTTPS prevent MITM?
HTTPS is vital in preventing MITM attacks as it makes it difficult for an attacker to obtain a valid certificate for a domain that is not controlled by him, thus preventing eavesdropping.
Can HTTPS Mitm?
The HTTPS protocol prevents MITM attacks. The HTTPS protocol is pretty complex, but all we need to know is that HTTPS uses a trusted Certificate Authority (CA) to sign a certificate.
You can use your own certificate authority by passing the –set confdir=DIRECTORY option to mitmproxy. Mitmproxy will then look for mitmproxy-ca.pem in the specified directory.
Can you use mitmproxy to decrypt on the fly?
Mitmproxy can decrypt encrypted traffic on the fly, as long as the client trusts its built-in certificate authority. Usually this means that the mitmproxy CA certificates have to be installed on the client device. By far the easiest way to install the mitmproxy certificates is to use the built-in certificate installation app.
How to prevent mitmproxy and mitmdump from intercepting traffic?
It is recommended to use the passthrough feature in order to prevent mitmproxy and mitmdump from intercepting traffic to these specific domains. If you want to intercept the pinned connections, you need to patch the application manually. For Android and (jailbroken) iOS devices, various tools exist to accomplish this.
Can a ISP intercept an encrypted communication?
Plaintext communication, such as plain HTTP or FTP, can be intercepted, analyzed and modified by the ISP without anybody knowing. This is why you should never used plaintext communication if it is in any way possible. Encrypted communication, such as HTTPS, FTPS, SFTP, etc., can also be intercepted, but the user will know that this is happening.
