HIGH: Accessible Hadoop Report

DESCRIPTION LAST UPDATED: 2023-12-12

DEFAULT SEVERITY LEVEL: HIGH

This report identifies hosts that are running Hadoop and have either the NameNode or DataNode web interfaces running and accessible to the world on the Internet.

At a minimum, this can allow for information-gathering against the target organization.

In other instances, it may allow a threat actor to manipulate the Hadoop instance.

Severity levels are described here.

Track exposed Hadoop instances on our Dashboard.

Fields

  • timestamp
    Time that the IP was probed in UTC+0
  • severity
    Severity level
  • ip
    The IP address of the device in question
  • protocol
    Protocol that the response came on (always TCP)
  • port
    Port that the response came from (50070/TCP or 50075/TCP)
  • hostname
    Reverse DNS name of the device in question
  • version
    Running version of Hadoop
  • tag
    Will always be hadoop
  • asn
    ASN of where the device in question resides
  • geo
    Country where the device in question resides

    State / Province / Administrative region where the device in question resides
  • city
    City in which the device in question resides
  • naics
    North American Industry Classification System Code
  • hostname_source

  • server_type
    The type of service that responded; this value is either "namenode" (response to probe on port 50070/TCP) or "datanode" (response to probe on port 50075/TCP); fields that contain data from only one type of response are denoted with either "namenode" or "datanode"
  • clusterid
    Unique ID of the cluster
  • total_disk

  • used_disk
    The amount of disk space used by Hadoop (in bytes) (namenode responses only)
  • free_disk
    The amount of disk space free to Hadoop (in bytes) (namenode responses only)
  • livenodes
    The first live datanode name listed in the response (namenode responses only)
  • namenodeaddress
    Trivial hostname of the NameNode that the DataNode is associated with (datanode responses only)
  • volumeinfo
    The path that the hadoop data is stored in (datanode responses only)
  • sector
    Sector the device belongs to
