Aren’t self-signed certificates vulnerable against MITM attack? What measures did Tor take to prevent MITM attack against self-signed certificates?
Continue reading Why does Tor use self-signed certificates? Isn’t it insecure?
Case One: A Tor exit node sending data forward to a website server.
In this case, a MITM attack can easily success because the traffic is not encrypted. However, the MITM does not know who sent the data originally, it only knows the fact t… Continue reading When a server is sending data back to client, is it vulnerable against MITM attack? How to prevent such kind of MITM attack?

Session keys are generated during TLS handshake and are transferred from clients to server through asymmetric encryption FOR ONCE.
However, I have heard that session keys are single-use, which mean a new set of session keys are going to be… Continue reading How are session keys transferred between a client and a server?
I teleworked for a medium-sized software company. We had a network architect who offered me a firewall to install so I could securely access on-premises resources and play around with some configuration settings because I’m interested in s… Continue reading Possible rogue admin monitoring my online activities
As already discussed on this platform, TLS Client Hello messages are not encrypted, since they contain "no sensitive data".
When sniffing HTTPS requests with wireshark, I can see the domain I am trying to access in the Client Hel… Continue reading TLS ClientHello leaks HTTP host header
This is a fundamental question, but, I’m interested in understanding the "venn diagram" of attack vectors between wired and Wi-Fi connections.
What are the attacks that both wired and Wi-Fi are vulnerable to? And what are the att… Continue reading Overlap between Wired vs WiFi vulnerabilities
Lately, while using a proxy, I got a certificate error for a website. Firefox gave a warning that the connection would not be secure. The certificate looked like the correct one (checked from a different IP) though.

Is there a point in being MITM nowadays since HTTPS makes it impossible to make sense of sniffed data and HSTS prevents SSL stripping?
In the near future, I will have about 50 remote computers to manage. These will be physical PCs running Debian 11, distributed all over the country. They will automatically perform a special kind of measurement repeatedly, and upload the r… Continue reading Reverse Shell for managing unreachable remote computers
