Weird DNS queries captured with Wireshark Started by user1000000 , Aug 31 2010 03:02 PM Please log in to reply 10 replies to this topic #1 user1000000 user1000000 Members 21 posts OFFLINE Local time:05:24 AM Posted 31 August 2010 - 03:02 http://www.bleepingcomputer.com/forums/t/344277/weird-dns-queries-captured-with-wireshark/ PM Hi! I've been using Wireshark and reading about it, but I wanted to ask you guys for some help. I've captured a few DNS queries that just don't look right to me. I've googled about this, but it's been difficult because the strange queries don't even have an IP address or name. The lines in Wireshark read something like this: 105 7.702967 192.168.1.2 156.154.70.22 DNS Standard query A idjbqddtkn.lan 106 7.703266 192.168.1.2 156.154.70.22 DNS Standard query A fjakwvjsij.lan 107 7.705037 192.168.1.2 156.154.70.22 DNS Standard query A zsrhyyjarh.lan and then are immediately followed by three corresponding answers like these: 108 7.830126 156.154.70.22 192.168.1.2 DNS Standard query response, No such name 109 7.830126 156.154.70.22 192.168.1.2 DNS Standard query response, No such name 110 7.830126 156.154.70.22 192.168.1.2 DNS Standard query response, No such name I'm attaching a JPEG file. I didn't upload the wireshark file because it's just a bit over 512k, so if needed, I can gladly submit it. The operating system I'm using is Windows XP Professional with SP3, and it's updated until today. What I did to get that capture was simply opening up wireshark, and then opening up my Google Chrome v. 5.0.375.127 browser. After the usual home page, I came to bleepingcomputer. Thanks a lot in advance for your help! I'll keep googling about this, but until now I haven't found

Opening chrome takes only a second, as it should. But as soon as I click on any of the thumbnailed sites (reddit.com, as an example), I have to wait. There's nothing in the browser indicating that it's loading, other than www.reddit.com appearing in the URL. I got curious, and started running WireShark to see no such name what might be causing the slowdown. That's when I noticed the following entries (after I clicked the link): 21 7.971612 192.168.1.126 192.168.1.1 DNS Standard query A pazkytgbcc.lan 22 7.972368 192.168.1.126 192.168.1.1 DNS Standard query A krxzlmahld.lan 23 7.973469 192.168.1.126 192.168.1.1 DNS Standard query A idbjtwdafg.lan 24 7.989505 192.168.1.1 192.168.1.126 DNS Standard query response, No such name 25 7.990754 fe80::401e:5f23:4885:605 ff02::1:3 LLMNR Standard query A pazkytgbcc 26 7.991031 192.168.1.1 192.168.1.126 DNS Standard query response, No such name 27 7.991580 192.168.1.126 224.0.0.252 LLMNR Standard query A pazkytgbcc 28 7.992852 192.168.1.1 192.168.1.126 DNS Standard query response, No such name 29 7.993054 fe80::401e:5f23:4885:605 ff02::1:3 LLMNR Standard query A krxzlmahld then later 89 12.818203 192.168.1.126 192.168.1.255 NBNS Name query NB PAZKYTGBCC<00> 90 12.818324 192.168.1.126 192.168.1.255 NBNS Name query NB KRXZLMAHLD<00> 91 12.818401 192.168.1.126 192.168.1.255 NBNS Name query NB IDBJTWDAFG<00> 92 13.568167 192.168.1.126 192.168.1.255 NBNS Name query NB PAZKYTGBCC<00> 93 13.568337 192.168.1.126 192.168.1.255 NBNS Name query NB KRXZLMAHLD<00> notice that these are repeating "hosts" from the A queries above. Any idea what's causing this? How do I fix it? This makes browsing terribly slow, and my wife is getting frustrated. I've tried adding these entries to the hosts file (which, Vista makes incredibly difficult), but to no avail. The hosts seem to be different each time, and I see no standard pattern. I'
