DINETHOSTING / curvecheese.com

DINETHOSTING aka Digital Network JSC are a large Russian host that regularly hosts malware sites. Yesterday I came across the domain curvecheese.com (85.192.45.83) being used in a malicious spam run. This is in a block 85.192.32.0/20 allocated to this host.

I tend to block DINETHOSTING ranges as soon as I see malware on them. If you are blocking this host, I would recommend you add 85.192.32.0/20 to your blocklist.

Redret domains to block 10/1/12

After a quite couple of weeks, the Redret spam has started again using the domains and IPs listed below. Some are familiar, some are new. In some cases blocking whole IP ranges is the best idea.

Apparently, it refers to James Cameron and not David Cameron. Payload site is hosted on 79.137.237.67 which is the now infamous Digital Network JSC in Russia (aka DINETHOSTING). Blocking 79.137.224.0/20 would be good for your health.

The link goes through a legitimate hacked site to a malicious payload on ciredret.ru/main.php, hosted on 79.137.237.63. Unsuprisingly this is Digital Network JSC in Moscow (aka DINETHOSTING) who are involved in much of the recent malware spam runs. Blocking 79.137.224.0/20 is highly recommended.

A link in the email goes to a legitimate but hacked site, users are forwarded to billycharge.com on 79.137.237.63. This IP is on Digital Networks CJSC in Russia (aka DINETHOSTING), a wholly black hat operation - you should block access to 79.137.224.0/20 if you haven't already done so. The Wepawet report is here , VT shows 0/43 detections for the exploit page although the download malware should tickle at least some scanners.

"Epidemic in Guinea" spam / curedret.ru

An interesting twist on malware spam:

Date:      Tue, 6 Dec 2011 10:19:25 +0530
From:      "MARIE Grover" [victimname@hotmail.com]
Subject:      Re: Epidemic in Guinea

The government is hiding this fact, but there is a new epidemic in Guinea

I got to know it from friends of mine, they are there right now. Here you can find the instruction what to do not get infected

Read it! 

Perhaps the spammers have a sense of irony, because if you click the link you get directed to a legitimate but hacked site and then bounced to curedret.ru on 79.137.237.63 which attempts to load the Blackhole Exploit kit. This belongs to Digital Networks CJSC (aka DINETHOSTING) in Russia.. blocking the entire 79.137.224.0/20 range is probably a very good idea as this block is full of malicious sites. The Wepawet report for this page is here.
