Backdoor ‘Olyx’

In my last blog post, I’ve discussed the early features of RAT ‘Blackhole’. Although, it was then in its early stage, I find this type of offensive development interesting due to the fact that they emerge and distribute as a hacking tool, with functional backdoor client-server mechanism.

Last month, we have spotted a new piece of malware, a backdoor server called ‘Olyx’. The file is a Mach-O binary and the traces of the working directory suggest that the Mac user name is ‘yxl’. So, this is where the name ‘Olyx’ came.

Backdoor ‘Olyx’ was spotted in a package called ‘PortalCurrent events-2009 July 5.rar”, where the content suggest that it was extracted from Wikipedia community portal current events 2009 July 5 page.  If you will visit the Wikipedia current events 2009 July 5 page, and compare the screenshot below, you’ll find it very similar.

However, the extracted page includes a folder which contains photos of the 2011 June 15th protest in Athens, Greece and alongside the two malicious binary executable:

There’s another folder called ‘Photo-Current events 2009 July 5′, which contains 21 (disturbing) photos.

Q: So, the question now is, what happened on ‘2009 July 5′ ?

The World Uyghur Congress website describes it,

On 5 July 2009, Uyghurs in Urumqi, the capital of East Turkestan, staged a peaceful protest which was suppressed by Chinese security forces and subsequently led to ethnic unrest in the city that left hundreds of people dead.

Q: Ok, that was 2 years ago right?

Yes, and in a press released titled “Worldwide Uyghur Protests on Second Anniversary of 5 July 2009″ describes the present,

On July 5, 2011 and in the days surrounding July 5th, the WUC called the Uyghurs in exile and their supporters around the globe to stage demonstrations and other actions to commemorate the second anniversary of one of the saddest and most tragic days in the history of the Uyghur people and of East Turkestan and to ensure that the world does not forget about the devastating plight of the Uyghur people.

So, there’s a call for an organized demonstration to remind the whole world of the 2009 event, and in support for Uyghur’s human rights and freedom.

Q: What’s the protest? This Facebook invitation page explains,

Approaching the second anniversary of these events, and despite international calls, no independent investigation into the incident has been allowed by the Chinese authorities and the number of people killed, detained, imprisoned, executed and disappeared remains unclear.

The activities surrounding this protest clearly took place in the cyberspace, resulting to attacks as described in press released titled  World Uyghur Congress (WUC) Victim of DDoS Cyber Attacks,

Approaching the second anniversary of the 5 July 2009 events, the World Uyghur Congress (WUC) has again been the victim of cyber attacks.

So, how do you think Backdoor ‘Olyx’ fits in this picture?

The discovery of this threat should remind Mac users to carefully consider security and the real-life consequences of getting pwned. Remember, this type of threats are on the mission, and this is not cybercriminal that monetize infection nor steals money.

    Why hasn’t Apple updated XProtect for this? They seem to be really proactive in protecting all variants of MacDefender.
