Money for Nothing and Coins for Free

Beginning in mid-September 2017, we started seeing a new abuse scheme on .ch and .li domains. The websites in question were running on outdated software and inevitably, hackers exploited some well-known vulnerability in order to inject malicious code. At this point we would usually expect an exploit kit in the website’s content with the purpose of infecting the victim’s machine with malware. In these cases however, the Javascript inject often looked somewhat like the following:

This code is designed to run in the background of the victim’s browser and immediately starts an endless loop of intensive computations at full pace, effectively turning the browser into a hash-crunching mule for the sake of distributed mining of cryptocoins, with profits going directly to the hacker.

11th October 2017, DNSSEC key rollover of the root zone, be ready the key is here!

On the 27th September, ICANN announced the postponement for the KSK rollover. More information can be found here.

As of July 11th, the new key is published in the root zone and your resolver should start updating its trust anchors automatically!

94 .ch & .li domain names hijacked and used for drive-by

A Swiss domain holder called us today telling us that the .ch zone points to the wrong name servers for his domain.

The NS entries were ns1.dnshost[.]ga and ns2.dnshost[.]ga. We contacted the registrar and soon realized that this is not the only domain that had unauthorized changes. We identified 93 additional .ch and .li domain names that pointed to the two rogue name servers. While domain hijacking by pointing to a rogue NS is a known attack,  94 domains on a single day is very unusual. So we analyzed what the hijacked domains were used for and soon found out that they are used to infect internet users with malware.

Visitors to the hijacked domains were redirected to the Keitaro TDS (traffic distribution system):

hXXp://46.183.219[.]227/VWcjj6

A TDS decides where to redirect the visitor to, often depending on its IP address (i.e. country),
user agent and operating system.

A dead end may look like the following:

hXXp//46.183.219[.]227/favicon.ico
hXXp://46.183.219[.]227/www.bingo.com

And the visitor will be redirected to Google.

However, in some cases, the visitor is redirected to the Rig Exploit Kit:

hXXp://188.225.87[.]223/?doctor&news=...&;money=...&cars=236&medicine=3848
hXXp://188.225.87[.]223/?health&news=...
...

And the visitor gets infected.

The payload is Neutrino Bot:

MD5: a32f3d0a71a16a461ad94c5bee695988
SHA256: 492081097c78d784be3996d3b823a660f52e0632410ffb2a2a225bd1ec60973d).

It gets in touch with its command and control server and grabs additional modules:

hXXp://poer23[.]tk/tasks.php
hXXp://poer23[.]tk/modules/nn_grabber_x32.dll
hXXp://poer23[.]tk/modules/nn_grabber_x64.dll

A little later, it also gets an update

hXXp//www.araop[.]tk/test.exe

MD5: 7c2864ce7aa0fff3f53fa191c2e63b59
SHA256: c1d60c9fff65bbd0e3156a249ad91873f1719986945f50759b3479a258969b38)

Status

The rogue NS were inserted in the .ch zone file at around 13:00 today. The registrar discovered soon what happened and rolled back the unauthorized changes. At 16:00 all of the changes in the .ch & .li zone were reverted and the NS records pointed to the legitimate name servers again.

[Update 10.7.17 17:15]

Gandi the registrar of the 94 domain names has written a blog post, as well as SCRT the domain holder that initially informed us about the domain name hijacking of scrt.ch. SCRT also showed how Strict Transport Security protected their recurring visitors from being redirected to the bogus website!

DNSSEC Signing for .ch and .li on the Rise

The share of DNSSEC signed domain names in .ch and .li reached 1% for the first time in June 2017. While this is still a very low number compared to other ccTLDs, the number of DNSSEC signed domain names is increasing at a high rate for the last two quarters.

DNSSEC

The Domain Name System Security Extensions (DNSSEC) is a set of technologies that secures the origin authentication and data integrity of the Domain Name System. It allows to detect DNS records that have been modified on the way from the authoritative name server to the client using a domain name. This helps to protect Internet users from going to bogus websites.

In addition from protecting Internet users from cybercriminals and state sponsored actors, DNSSEC is the base for important standards such as DNS-based Authentication of Named Entities (DANE).

DNSSEC in .ch and .li

DNSSEC was enabled for the .ch and .li zones in 2010 but unfortunately received a slow adaptation by domain holders. From 2013 there was a slow but steady growth of domain names signed with DNSSEC. In November 2016 we noticed a increased rate of DNSSEC signed domain names that accelerated in April 2017.

From now on SWITCH will publish statistics about the number of signed domain names for both ccTLDs .ch and .li on the nic.ch and nic.li website.
