There are a few ways to know why a hacker targeted you and whether there are vulnerable ports on your machine.
1) Look for unusual activity.If you've noticed any unusual activity on your computer, such as pop-up ads, slow performance, or unexpected programs, then it's possible that you've been hacked.
2)Scan your computer for malware.There are a number of free and paid tools that you can use to scan your computer for malware. If you find any malware, then you'll need to remove it immediately.
3) Check your firewall settings.Make sure that your firewall is enabled and that it's blocking all incoming connections that you don't recognize.
4) Look for open ports (search for port scanner on google to check for open ports).You can use a port scanner to see if there are any open ports on your machine. If there are, then it's possible that these ports are vulnerable to attack.
Here are some additional tips to help you protect your computer from hackers:
1) Keep your software up to date. Software updates often include security patches that can help to protect your computer from known vulnerabilities.
2) Use strong passwords. Your passwords should be at least 12 characters long and should include a mix of uppercase and lowercase letters, numbers, and symbols.
3) Be careful about what websites you visit and what files you download. Only visit websites that you trust and only download files from reputable sources.
4) Use a firewall and antivirus software. A firewall can help to block unauthorized access to your computer, and antivirus software can help to detect and remove malware.
By following these tips, you can help to protect your computer from hackers and keep your data safe.

when the feature called "Port scan protection" in the Firewall module is enabled. "Port scan protection" detects and blocks attempts to find out which ports are open. Port scans are frequently used by hackers to find out which ports are open on your device.
A port scan is a common technique hackers use to discover open doors or weak points in a network. A port scan attack helps cyber criminals find open ports and figure out whether they are receiving or sending data. It can also reveal whether active security devices like firewalls are being used by an organization.
According to the SANS Institute, port scanning happens to be one of the most popular tactics used by attackers when searching for a vulnerable server to breach. These cybercriminals often use port scanning as a preliminary step when targeting networks.
closed. A closed port is accessible (it receives and responds to Nmap probe packets), but there is no application listening on it. They can be helpful in showing that a host is up on an IP address (host discovery, or ping scanning), and as part of OS detection.
Fundamentally, it is not a crime to conduct a port scan in the United States or the European Union. This means that it isn't criminalized at the state, federal, or local levels. However, the issue of consent can still cause legal problems for unauthorized port scans and vulnerability scans.
"Port scan protection" detects and blocks attempts to find out which ports are open. Port scans are frequently used by hackers to find out which ports are open on your device. They might then break into your device if they find a less secure or vulnerable port.
To block port scans, you need to enable filters 7000 to 7004 and 7016. Please ensure that you read the filter descriptions, as some of them have warnings attached. The following filters detect and/or block port scans and host sweeps.
If one IP address is running a lot of scans on different ports, it can be an indicator of malicious activity. Statistical models can also be used to determine if scanning behavior differs from a baseline of normal behavior on the network.
I would not disable port scans your asking for it. Run a port scan from inside your firewall (if you have one), to see what internet services are installed on your machine. Run this test for all ports (1-65535) and for all protocols (UDP and TCP).
Port blocking thus affects the traffic associated with a particular combination of port number and transport protocol on that ISP, regardless of source or destination IP address. The practice can potentially prevent the use of particular applications altogether by blocking the ports those applications use.
Press the Windows key + R, then type "cmd.exe" and click OK. Enter "telnet + IP address or hostname + port number" (e.g., telnet www.example.com 1723 or telnet 10.17. xxx. xxx 5000) to run the telnet command in Command Prompt and test the TCP port status.
Vulnerability Scans: Vulnerability scanners take it one step beyond port scans and will detect not just open ports and operating systems, but if the host is vulnerable to a list of known exploits based on the implementations of their operating systems and services running on open ports.
A port scanner is an application which is made to probe a host or server to identify open ports. Bad actors can use port scanners to exploit vulnerabilities by finding network services running on a host. They can also be used by security analysts to confirm network security policies.
Though there are a number of ways to detect an active network scan, the primary detection tool is an Intrusion Detection System (IDS) and Intrusion Prevention System (IPS).
However, hackers can also use Nmap to access uncontrolled ports on a system. They can run Nmap on a targeted approach, identify vulnerabilities, and exploit them. But Nmap is not only used by hackers - IT security companies also use it to simulate potential attacks that a system may face.
A port scanner sends a UDP or TCP network packet that asks the port about its status. The results will uncover network or server status, which can be one of the following: open, closed and filtered.
A port scan can provide a wealth of information about a target system. In addition to identifying if a system is online and which ports are open, port scanners can also identify the applications listening to particular ports and the operating system of the host.
It is mainly performed to identify if a port is sending or receiving any information. Port scanning also involves the sending of data to specific ports and analyzing the responses to identify vulnerabilities. It is also one of the techniques used by attackers to discover devices/services they can break into.
