Drive-by code and Phishing on Swiss websites in 2014

In 2014, about 1,800 Swiss websites were cleaned from drive-by code, compared with 2,700 in 2013, a decline of 33%. At the same time, the number of phishing cases affecting .ch and .li top-level domains rose from only a handful in 2013 to more than 300.

Drive-by code on Swiss websites in 2014

Last year, 35,796 suspicious drive-by URLs in the .ch and .li top-level domains were reported to SWITCH. Security experts from SWITCH-CERT automatically sent requests to these servers and analysed the responses, looking for malicious code injected into the HTML source code. When an expert identified malicious code, the registrar or domain name holder and the web hoster were notified and asked to remove it within one working day. This was done for 1,839 domain names in 2014. In 1,493 (81%) cases, the code was removed by the web hoster or domain holder within one day. For the other 346 domains, the deadline was not met, and the domain name was temporarily suspended to prevent further damage to website visitors. Some 264 (14%) of the infected websites were cleaned of malicious code, with the remaining 82 domain names having to be reactivated after five days, the maximum suspension time by law. A request for identification was sent to the holders of all 82 domains, resulting in an additional 59 (3.2%) of websites being cleaned. A total of 23 (1.3% of all notified) domain names were deleted after 30 days because the domain holder failed to respond to the identification request.

A look at a phishing website

Yesterday we came across a phishing website under .ch where we were able to download the phishing kit. A phishing kit is an archive file which contains all the relevant files for hosting a phishing website. In this case, the archive contained some static HTML, JS and image files for hosting the phishing form, but also a PHP file for sending the data to the perpetrator, and – most interestingly –an .htaccess file. The .htaccess file is a configuration file used by some popular web servers, which allows the user of a website to override a subset of the server’s global configuration for the directory that the file is located in and all its sub-directories.

A phishing website is frequently only accessible from the targeted country. In our case, this was controlled by the .htaccess file which contained a large list of IP address ranges from where it is allowed to access the site. As an incident handler, we often get reports of malicious websites that we cannot verify with IP addresses from Swiss ISPs. An unwary user might think that the phishing website has already been taken down, but that is not the case. The user is just not allowed to access the phishing website from its IP address.

Swiss economy makes online security its priority

Switzerland is one of the safest countries in the world. To make also the Internet a secure place in Switzerland, the Swiss online economy has started the Swiss Internet Security Alliance (SISA). The goal of the alliance is to make Switzerland the “cleanest” Internet country in the world! The organization launched an online security check today which allows internet users to clean and protect their systems.

Offering more security
The founding of the Swiss Internet Security Alliance is a sign of its members’ commitment to making the Internet a secure place in Switzerland. The association brings together expert knowledge from representatives of various sectors and promotes information-sharing amongst competitors.

Overcoming challenges together
The Swiss Internet Security Alliance focuses on its main assets – the knowledge, experience and technical expertise of its members. Its members asut, Centralway, credit suisse, cyscon Schweiz, Lucerne University of Applied Sciences and Arts, Hostpoint, Migros Bank, PostFinance, Raiffeisen, Sunrise, Swisscard, Swisscom, SWITCH, UBS, upc cablecom and Viseca have longstanding experience in dealing with online security.  The association is open to other interested parties. More information can be found in the press release:

Comprehensive security check
Upon founding the association, the Swiss Internet Security Alliance is launching a security check. The Swiss Security Check provides protection on three levels.

  1. Users with outdated or incorrectly configured software who are therefore subject to a security risk, will find this out within seconds.
  2. If there is suspicion of malware, the malware cleaner helps with the diagnosis and resolution of the problems.
  3. A cyber vaccine completes the protection and keeps electronic pests at bay.
