Domain: amp.crack-zone.ru

Domain: amp.crack-zone.ru

If you are seeing queries for this domain, than you are likely participating in DNS Amplification attacks and your DNS server is probably reachable from the internet and has recursion enabled.

If you are seeing responses for this domain.. unlucky. You are currently beeing DDOS-ed! Good luck.


IPtables:


There are two iptable rules available. If your distribution supports Iptables 'u32' module pick this one, otherwise use the 'string' rule.

U32:
iptables --insert INPUT -p udp --dport 53 -m u32 --u32 "0x28&0xFFDFDFDF=0x03414d50 && 0x2c&0xFFDFDFDF=0x0a435241 && 0x30&0xDFDFFFDF=0x434b2d5a && 0x34&0xDFDFDFFF=0x4f4e4502 && 0x38&0xDFDFFF00=0x52550000" -j DROP -m comment --comment "DROP DNS Q amp.crack-zone.ru"

More U32 rules can be found here:

String:

A Who-Am-I from China


Today I found the domain "whoami.akamai.com" in my log files. After concluding that there was no amplification in there, I looked at who requested this domain. Normally there is one request for these 'new'  domains. ( mostly an Ecatel IP ) But not today, over a hundred different IPs scrolled by..

The queries were also performed with only the Recursion Desired bit set, no eDNS as I usually see.

Most IPs only requested the domain once.. but why this domain? The IPs are scatered over a few AS-es:

     71  AS4134 Chinanet
     40  AS4837 CNCGROUP China169 Backbone
      7  AS23650 AS Number for CHINANET jiangsu province backbone
      6  AS9808 Guangdong Mobile Communication Co.Ltd.
      4  AS38283 CHINANET SiChuan Telecom Internet Data Center
      3  AS17816 China Unicom IP network China169 Guangdong province
      2  AS4812 China Telecom (Group)
      2  AS4808 CNCGROUP IP network China169 Beijing Province Network
      2  AS24444 Shandong Mobile Communication Company Limited
      1  AS7473 Singapore Telecommunications Ltd
      1  AS58424 #3BEo, Sangkat Beoun Prolit, Khan 7Makara, Phnom Penh.
      1  AS56046 China Mobile communications corporation

      1  AS24445 Henan Mobile Communications Co.,Ltd
      1  AS18118 CITIC Networks Management Co.,Ltd.

Dhcp, dynamic - sound like home connections. Botnet?

WhoAmI.akamai.com

 As it turns out this sub domain is something special.
The A record response for this domain is the IP from which the request come from. So if you run a local DNS server you will have your (WAN) IP returned. When using a remove DNS server, that IP will be returned. In case of a chain of forwarding DNS servers, the IP of that last one in the chain will be returned.


Google Public DNS:

dig whoami.akamai.com @8.8.8.8

....
;; ANSWER SECTION:

whoami.akamai.net.      94      IN      A       74.125.17.147

My query was forwarded to 74.125.17.147 by Google. For load balancing purposes I guess. Perhaps using eDNS +client.

But why request this domain from every open DNS server in the world?

The people behind this scan can see the difference in 'open DNS servers' if it is a 'open resolver' or an 'open forwarder'.  Perhaps this makes a significant difference when performing DNS amplification attacks.. perhaps it is just nice to know.

When the responses to these queries are properly logged on could  generate a real nice graph of what open forwarders hide behind what open resolvers... I want that graph now!!

I am assuming there are a lot more open forwarders than there are open resolver. But I have no stats on that matter. Perhaps this was a small botnet making these requests.. but why request it so many times as the queries are almost all from China it cannot be related to Geo diversity. Pretty confusing.

If anyone has any idea about this all.. Let me know!

Domain: dnsamplificationattacks.cc

Domain: dnsamplificationattacks.cc

# This domain does not belong to me # (yet)

Well how about that. Some one bought me a domain name! Maybe I can seize it... ;-)

If you are seeing queries for this domain, than you are likely participating in DNS Amplification attacks and your DNS server is probably reachable from the internet and has recursion enabled.

If you are seeing responses for this domain.. unlucky. You are currently beeing DDOS-ed! Good luck.


IPtables:


There are two iptable rules available. If your distribution supports Iptables 'u32' module pick this one, otherwise use the 'string' rule.

U32:

Domain: marusiaattack.pw

Domain: marusiaattack.pw

If you are seeing queries for this domain, than you are likely participating in DNS Amplification attacks and your DNS server is probably reachable from the internet and has recursion enabled.

If you are seeing responses for this domain.. unlucky. You are currently beeing DDOS-ed! Good luck.


IPtables:


There are two iptable rules available. If your distribution supports Iptables 'u32' module pick this one, otherwise use the 'string' rule.

U32:
iptables --insert INPUT -p udp --dport 53 -m u32 --u32 "0x28&0xFFDFDFDF=0x0d4d4152 && 0x2c&0xDFDFDFDF=0x55534941 && 0x30&0xDFDFDFDF=0x41545441 && 0x34&0xDFDFFFDF=0x434b0250 && 0x38&0xDFFF0000=0x57000000" -j DROP -m comment --comment "DROP DNS Q marusiaattack.pw"

More U32 rules can be found here:

https://github.com/smurfmonitor/dns-iptables-rules/blob/master/domain-blacklist.txt

String:
iptables --insert INPUT -p udp --dport 53 -m string --from 40 --to 58 --algo bm --hex-string '|0D6d61727573696161747461636b02707700|' -j DROP -m comment --comment "DROP DNS Q marusiaattack.pw"
