QuickScan alternatives

This small utility can retrieve information from the WHOIS database, to see who owns an IP address or domain name. Besides that, it can obtain information from the system itself, like the uptime. DMitry also has the option to search for email addresses, perform a TCP port scan, and use modules specified by the user.

Masscan can be compared with other tools like Nmap. Due to its focus on high performance, this tool can be used when many systems have to be scanned at once. It can scan all internet hosts on IPv4 within 5 minutes. This impressive statistic makes the tool loved by those that do security research.

Zenmap is a graphical user interface (GUI) for Nmap. It can be of great help to start a network scan by simply selecting the options you want. Besides Linux, it also runs on Microsoft Windows, macOS, BSD, and other flavors of Unix.

One of the strengths of Zenmap is the ability to store profiles, which can be reused for later scans. The command creator is another one, which helps interactively create the right nmap commands. Recent scans are stored in a searchable database and scan results can be saved and compared.

Nmap is short for "Network Mapper". It is a free and open source utility for network discovery and security auditing. It was release in September of 1997 by Gordon Lyon, commonly known under his pseudonym "Fyodor".

DNSChef is a DNS proxy that can be used terminate or intercept traffic for DNS traffic. This might be useful during a penetration test or when researching malware and manipulate the actual DNS responses.

DNSteal allows you to extract files from a machine through DNS requests. This can be used to circumvent security measures and test them against data leakage. The tool supports compression and allows for multiple files to be transferred.

SubFinder is a tool to scan domains and discover subdomains. This may be useful during the reconnaissance phase of penetration testing where information is collected. Some subdomains may reveal sensitive data or point to interesting targets such as a backup location.

When a project requires resolving or guessing host names, then this tool is a great addition to the toolkit. It focuses on 'fast' by using asynchronous operations. The list of names to try is provided with a wordlist.

Leviathan is a security tool to provide a wide range of services including service discovery, brute force, SQL injection detection, and exploit capabilities. The primary reason to use this tool is to do massive scans on many systems at once. For example to include a huge network range, country-wide scan, or even full internet scan.

Portspoof is a small utility with the goal to make port scanning by other much harder. It achieves this by showing all configured TCP ports to be in the 'open' state instead of closed or filter. The related ports are also emulating valid services. This way a port scan on the system will reveal many open ports and look to have legitimate services running.

This tool can be called a true 'inspector tool' as it helps to discover many types of data.

• Website information
• Domain and subdomain information
• Mail server information and email
• Phone details
• IP addresses
• Detection of used CMS

ThreatPinch helps to speed up collecting information from common resources like CVE databases or public WHOIS data. As it works from the browser, it is a helpful addition for people who have to perform forensics, security monitoring, or system administration. For example, getting the owner of a domain and IP address becomes almost instant knowledge.
