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.
RAT ‘BlackHole’
‘BlackHole’ is the latest remote administration tool (RAT) and is available both in Windows and Mac.
Hacktool such RAT employs client-server program that communicates to its victim’s machine through its trojan server. The server application is installed on the victim while the client application is on the managing side.
The version suggest that ‘BlackHole’ is currently in its early stage. However, the author seems to start showcasing the following functionalities:
- Remote execution of shell commands.
- Opens webpage using user’s default browser.
- Sends a message which is displayed on the victims screen.
- Creates a text file.
- It is capable to perform shutdown, restart and sleep operation.
- It is capable to request for admin privileges.
Also, it is also capable to block users screen with this message: please refer this image.
Be wary of possible backdoor infection. Report suspicious application, especially if it is communicating to unknown or unfamiliar remote server.
Note: While checking the client-server capability, I just thought that it would be useful to capture a video for reference. (recommended screen 720pHD)
How to Remove Starfield
1) Kill the running process.
Using spotlight, type-in Activity Monitor and filter by searching starfieldUpdate and click Quit Process. Then, search offSyncService and click Quit Process.
If using Terminal, you may run the following command:
2) Delete Starfield internet plugins and components.
Using Terminal, you may run the following command:
3) It will require root password to remove the following files.
This instruction removes all the traces of Starfield. Stay safe!
**Note: If you find Starfield application useful, you may keep the ‘WBE Desktop Notified.App’ and ‘DesktopTools.App’.
Drag and Drop
This is unfortunate for business, and a worrying attack vector. The Mac App store was easily bypassed and cracked by this simple drag and drop process. Evidently, you’ll find it ‘Installed’ when you open the app.
Please be reminded that ‘deceptive packaging’ takes advantage of legitimate software and application packaging to obscure the possible execution of malicious code; and, this provides attacker a good opportunity.
iThreats ‘Home’
Welcome 2011! I’m pleased to share iThreats ‘Home’.This is a library of sources, discussing the latest trends, publication, research work and analysis surrounding Apple security.
Let’s be reminded of the fundamental principle about digital security as introduced by Bruce Schneier that “Security is a process, not a product”. Lack of awareness and complacency can be dangerous. Thus, a greater discussion and awareness is better, it promotes understanding, identification and how response help protect our data, systems and digital life.

Keep an eye for updates!
Window Shortcut – LNK File Format

Figure 01 – LNK Top Level File Structure
A computer shortcut (shortcut) is a small file containing a target URI or the name of a target program file that the shortcut represents. [wiki]
Microsoft Windows uses .lnk as the filename extension for shortcuts to local files, and .URL for shortcuts to remote files, like web pages.
Thanks to Jesse Hager for creating the specification document. Please refer this link http://www.wotsit.org/list.asp?al=L and search ‘LNK’ download good reference.
As observed, LNK trojan downloaders takes advantage of Command line string to perform malicious activity.
**Update**
0day on malformed Windows Shell Link (.LNK) Binary referred as CVE-2010-2568 and Microsoft Security Advisory (2286198)
LNK binary file format reference:
OS X users, please patch!
If you haven’t patch yet, then please do.

How do I know if I’m patched?
Click “About This Mac” and it should display Mac OS X version 10.5.7. You can do the same if you are using Safari by clicking “About Safari”, this should display Safari 4 (beta).
Why it is important to patch?
There are critical vulnerabilities that could allow malicious user (hacker, malware) to snoop and steal your information in background. Let me sight examples from vulnerabilities that has captured media attention (so, it means many attackers are aware of this).
Safari RSS
Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5.6, Mac OS X Server v10.5.6
Solution: The critical issue has been addressed in Security Update 2009-001 for Mac users and Safari 3.2.2 for Windows.
Impact: Accessing a maliciously crafted feed: URL may lead to arbitrary code execution.
Attacker can easily craft URL and execute javascript – and this could expose your personal and sensitive information.

Disk Images
Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5 through v10.5.6, Mac OS X Server v10.5 through v10.5.6
Solution: The critical issue has been addressed in Security Update 2009-002
Impact: Mounting a maliciously crafted disk image may lead to an unexpected application termination or arbitrary code execution.
This is very critical the fact that browser like Safari has enabled “Open safe files after downloading” by default. You can turn off this option in Safari by following the instructions below:
1. Open Safari
2. Open “Preferences” under the “Safari” menu
3. Click on the “General” tab
4. Un-check the “Open ‘safe’ files after downloading” box
5. Close Safari’s preferences
