What ports does malware use?
Malware uses various ports, often targeting common ones like 80 (HTTP), 443 (HTTPS) for stealthy command-and-control (C2) traffic, and 445 (SMB) for lateral movement, plus database ports (e.g., 1433, 3306) and remote access (e.g., 22, 3389); attackers exploit both standard services and specific malware-associated ports (like old Trojan ports) to spread, steal data, or launch attacks, using commonly open ports to blend in with normal traffic.Is port 8080 suspicious?
While ports 8080 and 8081 are useful for local development, they pose significant security, reliability, and performance risks in production. Instead, leverage reverse proxies, API gateways, and private networking to securely expose your services.What ports are mostly used by hackers?

What runs on port 143?
Port 143 is the default, unencrypted port for the Internet Message Access Protocol (IMAP), used by email clients to retrieve messages from a mail server, allowing synchronization across multiple devices by managing emails directly on the server.

Port 445 is primarily used by the Server Message Block (SMB) protocol in Windows networks for file and printer sharing, allowing devices to access shared resources directly over TCP/IP, bypassing older methods like NetBIOS. It's fundamental for network resource sharing, Active Directory (AD) operations, and remote access but is also a significant security vulnerability when exposed externally, as attackers frequently scan and exploit it for ransomware (like WannaCry) and malware.What runs on port 666?
Port 666 is historically associated with the Doom multiplayer gaming protocol and various malware families. While originally used for legitimate gaming, this port has become notorious as a common choice for trojans, backdoors, and other malicious software due to its symbolic number association.What runs on port 444?
Port 444 is primarily known as the standard port for the Simple Network Paging Protocol (SNPP), used for sending messages to pagers, but it's also used by specific applications like Palo Alto Networks' Panorama for logging and occasionally by other services for non-standard purposes, acting as a secondary HTTPS port or for specific middleware communication.
