SNMP/TCP probes from critical.io

[r.bhatia at ipax.at (Raoul Bhatia [IPAX])]

hi!

during the last couple of days, i noticed probes from some hosts that
present themselves as critical.io probe hosts, including but not
limited to, the following IP addresses:

* 184.154.42.194 / critical.io
* 69.64.43.135 / research1.critical.io
* 69.64.43.137 / research2.critical.io
* 69.64.43.142 / research3.critical.io
* 50.116.22.209

The systems present the following information via http:
 > This system is coordinating an internet-wide survey of open TCP
 > ports, service banners, SNMP system descriptions, and NetBIOS name
 > queries. The results of this survey will be used to uncover
 > systematic vulnerabilities in the equipment provided by ISPs to their
 > customers.

Have you noticed these probes and what are your thoughts on them?

Cheers,
Raoul
