Open SNMP Report

This report identifies hosts with SNMPv2 publicly accessible, that are responding to the community “public”, and that have the potential to be used in amplification attacks by criminals who wish to perform denial of service attacks.

Statistics for these hosts can be found here.

The OID being probed for is 1.3.6.1.2.1.1.1.0 (sysDescr) and if the host responds to that probe, the host is then probed for OID 1.3.6.1.2.1.1.5.0 (sysName). The analogous shell commands would be:

snmpget -c public -v 2c [ip] 1.3.6.1.2.1.1.1.0

snmpget -c public -v 2c [ip] 1.3.6.1.2.1.1.5.0

Fields

  • timestamp
    Time that the IP was probed in UTC+0
  • ip
    The IP address of the device in question
  • protocol
    Protocol that the DNS response came on (usually UDP)
  • port
    Port that the SNMP response came from
  • hostname
    Reverse DNS name of the device in question
  • sysdesc
    System Description as obtained from OID 1.3.6.1.2.1.1.1
  • sysname
    System Name as obtained from OID 1.3.6.1.2.1.1.5
  • asn
    ASN of where the device in question resides
  • geo
    Country where the device in question resides
  • region
    State / Province / Administrative region where the device in question resides
  • city
    City in which the device in question resides
  • version
    The SNMP probe version that the IP responded to (usually 2)
