In many cases, the software you use specifies the port for you. For example, when you connect tohttps://digitalocean.com, you’re connecting to thedigitalocean.comserver on port443, the default port for secure web traffic. Since it’s the default, your browser adds the port for you. In...
Secure Sockets Layer (SSL). The default port for MQTT over SSL/TLS is 8883. This port is used when the communication between the MQTT client and the server needs to be encrypted for enhanced security.
An open port 139 that allows inbound traffic from all external IP addresses is extremely dangerous. Any shared resources are exposed to the public internet. An attacker could also run the NetBIOS diagnostic tool Nbtstat to obtain information to help them startfootprintinga system they want to att...
When you use the internet, your computer dedicates ports to specific functions. For example, if you are accessing anHTTPSwebsite, your computer will direct this traffic to port 443. Port Forwarding, or port mapping, reroutes this data from one port to another. Many (but not all)VPN servic...
In this case, it is often obvious to the attacker which application you are using. If the attacker is familiar with the application, she may know how to exploit it. For instance, the application may use a configuration file called %webroot%\system.config. If files with the .config ...
indicators of a (failed) attempt to compromise the system. Indeed, the fix is not meant to prevent adding unauthorized devices (which these log entries are indicative of and can legitimately happen in a deployment context); it is intended to prevent unauthorized devices from sendingexploit ...
remote hosts to discover the type of traffic the server accepts. Malicious users often use this as a discovery tool to try to find vulnerable services to exploit (part of the reason to use a firewall in the first place), so you will use this to try to see what an attacker...
I have changed some of the data slightly to protect the innocent, but what you’re seeing here is an attacker sending a specially crafted cookie to our site in the hope that they may exploit a vulnerability or trick the site into disclosing some sensitive data. The cookie violates PHP’s ...

To explore these vulnerabilities, a malicious JS code must gain access to port 443 (which is possible if you use the default OWA authentication page): But in our network, all access to web resources is controlled by WWPass authentication, where any requests to url/owa/or/ecp/are redirect...
