Masscan: Open Source Network Scanner
Masscan is an open source network scanner that can scan the entire Internet in under 6 minutes. It uses asynchronous transmission, allowing it to achieve very high scanning speeds compared to traditional scanners.
What is MASSCAN?
MASSCAN is an open source network scanner developed by Robert David Graham. It is designed for quick, large-scale scans of the Internet by using asynchronous transmission. This allows MASSCAN to scan the entire public IPv4 address space in under 6 minutes, transmitting 10 million packets per second.
Unlike traditional scanners like Nmap, MASSCAN does not do port scanning, OS detection, version detection, or script scanning. Instead, it simply checks if a port is open or closed, allowing it to operate extremely quickly. The main use cases for MASSCAN are:
- Performing Internet-wide surveys of things like SSL servers, SMTP servers, RDP servers, etc.
- Large internal network audits where speed is critical
- Finding easy targets for deeper scanning by tools like Nmap
Some key capabilities and features of MASSCAN include:
- Transmits over 10mpps from a single machine
- Can scan the entire public IPv4 address space in under 6 minutes
- Lightweight and portable C code for easy compilation
- Powerful scripting capabilities for customized scans
- Advanced batching, throttling, and randomization options
- Easy output to binary, XML, grepable, and JSON formats
Overall, MASSCAN's extremely fast scanning makes it ideal for large-scale Internet surveys as well as quick discovery of low hanging fruit in internal networks. The simplicity of only checking open/closed allows it to operate at speeds unattainable by more feature-rich scanners.
