  • Complex UI
    The user interface can be overwhelming for beginners due to its complexity and the vast amount of data available, making it difficult to navigate without prior experience.
  • Subscription Costs

  • Potential for False Positives
    The data collected by Shodan might include false positives, where benign devices are flagged as vulnerabilities, thus requiring users to manually verify each finding.
  • Privacy Concerns
    Since Shodan indexes devices connected to the internet, this can include personal and residential hardware, leading to privacy concerns for individuals whose devices are inadvertently exposed.

  • 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: almost 2 years 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: almost 2 years 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: almost 2 years 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: almost 2 years 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.

  • What should I be doing as the sole sysadmin for a company to keep up with security?
    Personally, I was lucky enough to get a license to Nessus for my own scanning, however you can use OpenVAS for some free to scan. Scanners aren't 100% correct no matter where you go but it'll give you some things to look at. OpenVAS. Source: almost 3 years ago
