I do not like spam in my inbox sometimes I let them build up so I can blast through some patterns and dig up some badguys.

So I start off just looking at some auto insurance spam headers and see:

autoraste.com     188.229.19.202
Reported by dns5.registrar-servers.com

That IP address is not on blacklists and I have no other spam from that domain name BUT… a lookup of the mx records.

This is a lot of mail servers – so more that likely there is s shared hosting mass mail service here. or some unmanaged colo.

  • 10 eforward1.registrar-servers.com
    Blacklists: None
  • 10 eforward2.registrar-servers.com 38.101.213.202
    Blacklists: None
  • 10 eforward3.registrar-servers.com 205.251.134.191
    Blacklists: None
  • 15 eforward4.registrar-servers.com 69.160.33.74 30
    Blacklists: None
  • 20 eforward5.registrar-servers.com 50.30.32.27 30

    Blacklists:

    • BACKSCATTERER
    • MAILSPIKE-BL
    • SPAMCANNIBAL

Reported by dns2.registrar-servers.com

Next I search for registrar-servers.com in the headers of the email in my inbox reveals 88 spams from those servers THIS MONTH!

A search for 188.229.19.202 in the headers of the email in my inbox reveals only ONE THIS MONTH!

A search for 188.229.19. in the headers of the email in my inbox reveals only 33 THIS MONTH – so what IP address are the rest coming from?

The one that got me looking here was:188.229.19.202

Ok there are more but I am bored!

Check out the patterns

  • [95.64.32.*] 18 spams in 30 days
  • [188.229.19.*] 23 Spams in 30 days
  • [173.233.75.*] 7 Spams in 30 days
  • [130.93.43.*] 7 Spams in 30 days

NetRange: 173.233.64.0 – 173.233.95.255
CIDR: 173.233.64.0/19
OriginAS: AS40244
NetName: TURNKEY-INTERNET
NetHandle: NET-173-233-64-0-1

so after I pull all of those I decide to whittle it down and search for eforward – and I find another 33 spams in the last 30 days!

    [130.93.40.5] (26 spams 130.93.40.*)
  4. X-Spam-RBL-Report: [130.93.42.90] (6 spams 130.93.42.*)
    [10 eforward3.registrar-servers.com., 15 eforward4.registrar-servers.com., 20 eforward5.registrar-servers.com., 10 eforward1.registrar-servers.com., 10 eforward2.registrar-servers.com.]

Pattern matching:

  • [130.93.40.*] 26 spams
  • [130.93.42.*] 6 spams
  • [212.117.161.*] 1 spam

When it gets this deep an obfuscated it really does seem pointless to contact the abuse folks managing the servers – I just block them from delivering to our servers. AND THAT MAKES MY DAY!
