9 Best Angry IP Scanner Alternatives Reviewed 2021 (Free & Paid)
ZMap, just like Nmap and other network scanners can search for connected devices, probe ports, and discover services both in local and external networks. One of the biggest distinctions between the two tools is how they scan. Nmap was built to be a flexible multi-tool that can probe a large number of ports on a smaller number of devices. Where ZMap is optimized to probe an...
15 Best Nmap Alternatives Network Security Scanner
We also have the ZAnnotate on the ZMap project. This adds more metadata to IP addresses such as routing data and location.
Alternatives to Nmap: from simple to advanced network scanning
The headliner is the single-packet scanner ZMap. ZGrab is an application-state scanner that works alongside ZMap. ZTag annotates data outputted by ZMap with metadata, such as device information and any vulnerabilities found. ZBlacklist helps you quickly filter out IP addresses by organizations that have requested not to be scanned. ZAnnotate adds metadata to IPs such as...

  • Introducing OSINT Template Engine: An open source OSINT Tool.
    Transform OSINT sources such as shodan, bgpview & urlscan into templates which you can use to query & store any and each of the API endpoints they provide. Source: 10 months ago
  • Some outgoing ports (e.g, port 22) are blocked
    I'm a little surprised you're asking this but as you don't know - if you set the rulebase correctly, you won't get hammered by "public". A lot of people (of course not people here) don't do that which is why shodan.io is full of servers with SSH exposed to the world. Source: 10 months ago
  • Does anyone want to vet this job opportunity?
    Eh, request a full demo before signing anything. If they make you buy before you can try, move on. Just be advised that data they collect from your site may be used in a database that puts a target on your back. Similar to how shodan.io works. I would probe them on how they handle customer data and if data is shared, partitioned, or isolated to ensure safety from a platform leak. They want to be a security... Source: 10 months ago
  • Security issue or coincidence?
    My network is being hit by China and Russia many times per hour. Make sure your firewall is up-to-date and not have any services available on the Internet (WAN). Look at shodan.io which shows you _everything_ is searched on the Internet. Source: 11 months ago
  • Onion sites crawling: Weird mass "HTTP/1.1 200 " HTTP status line returning?
    In the cases of nginx or apache, I suspect they may be acting as proxies to some backend that also chooses not to send a reason phrase back. Searching for "Reason Phrase" yields a number of bug reports/frameworks that may omit it, and shodan.io shows apache tomcat and a few other services/software that omit the code as well.

  • My cousin leaked my public ip address to someone
    They already had your IP. The whole internet (IPv4 adress space) can be scanned in less than one hour (see: https://zmap.io. Source: over 1 year ago
  • The internet is a global village, not a metropolis
    The numbers above demonstrate that it is theoretically possible to mass scan the entire internet. Effective free-to-use tools can be used to perform mass scans, converting this academic opportunity into practice. ZMap, Masscan, and others promise to scan the entire public IPv4 address space in some ten minutes or so on a typical desktop computer with a gigabit Ethernet connection. Researchers proved that the time... - Source: dev.to / almost 2 years ago

  • Python Port Scanner: Faster than Nmap.
    Zmap (zmap.io) is probably the fastest port scanner. But afaik it's main usage is to scan 1 port on the whole internet instead of all ports on one IP (but you can, too). Source: over 2 years ago
