Fostering knowledge exchange among different generations of security researchers is maybe one of the best traits of a good security conference. Judging by its attendance, NoSuchCon can easily claim to be one of these. It's rare to see such a mix of young researchers and old gurus exchanging ideas and getting to know each other. Organized this year in Paris, NoSuchCon takes place in the premises of the Espace Oscar Niemeyer; admittedly, indeed a nice move putting a security conference within an art exposition center (congrats to the organizers :)).

Blog: Winnti returns with PlugX

webmaster@securelist.com (Dmitry Tarakanov) — 15 Apr 2013 16:30:00 +0400

Continuing our investigation into Winnti, in this post we describe how the group tried to re-infect a certain gaming company and what malware they used. After discovering that the company-s servers were infected, we began to clean them up in conjunction with the company-s system administrator, removing malicious files from the corporate network. This took a while because it was not clear at first exactly how the cybercriminals had penetrated the corporate network; we couldn-t find a way to completely stop attacks penetrating the network and malicious files kept appearing. An analysis performed by the gaming company itself led us to the conclusion that the infection started after establishing working contacts with a South Korean gaming company. This was also confirmed by our research: as we wrote before, the Winnti group is most active in East Asia and we identified 14 infected gaming companies in South Korea.

webmaster@securelist.com (Costin Raiu) — 26 Mar 2013 16:14:19 +0400

In the past, we've seen targeted attacks against Tibetan and Uyghur activists on Windows and Mac OS X platforms. We've documented several interesting attacks which used ZIP files as well as DOC, XLS and PDF documents rigged with exploits. Several days ago, the e-mail account of a high-profile Tibetan activist was hacked and used to send targeted attacks to other activists and human rights advocates. Perhaps the most interesting part is that the attack e-mails had an APK attachment - a malicious program for Android.

Blog: New Uyghur and Tibetan Themed Attacks Using PDF Exploits

webmaster@securelist.com (Costin Raiu) — 14 Mar 2013 14:55:00 +0400

On Feb 12th 2013, FireEye announced the discovery of an Adobe Reader 0-day exploit which is used to drop a previously unknown, advanced piece of malware. We called this new malware "ItaDuke" because it reminded us of Duqu and because of the ancient Italian comments in the shellcode copied from Dante Alighieri's "Divine Comedy". Previously, we posted about another campaign hitting Governments and other institutions, named Miniduke, which was also using the same 'Divine Comedy' PDF exploits. In the meantime, we've come by other attacks which piggyback on the same high level exploit code, only this time the targets are different: Uyghur activists. Together with our partner at AlienVault Labs, we analyzed these new exploits.
