If so, you may be the target of a spear phishing campaign designed to install a spyware on your Mac.
Here's a list of binaries signed by Apple Developer "Rajinder Kumar".
Detected as Trojan-Spy:OSX/HackBack.B:
• 1eedde872cc14492b2e6570229c0f9bc54b3f258 • 6737d668487000207ce6522ea2b32c7e0bd0b7cb • a2b8e636eb4930e4bdd3a6c05348da3205b5e8e0 • 505e2e25909710a96739ba16b99201cc60521af9 • 45a4b01ef316fa79c638cb8c28d288996fd9b95a • 290898b23a85bcd7747589d6f072a844e11eec65 — mentioned in yesterday's post.
Detected as Backdoor:OSX/KitM.A (includes screenshot feature):
Though the spear phishing payloads are not particularly "sophisticated", the campaign's use of German localization and the target's name (removed in the example above) does indicate the attackers have done some homework.
There's another case of Backdoor:OSX/KitM.A in the wild.
A German-based investigator reached out to us yesterday regarding OSX/KitM. (We wrote about it last week.) KitM stands for "Kumar in the Mac", which is our designation for spyware — related to OSX/Filesteal a.k.a. OSX/HackBack — that is signed using an Apple Developer ID in the name of Rajinder Kumar. The Developer ID has since been revoked by Apple.
This latest version of OSX/KitM used a Romanian C&C server called liveapple.eu during the period of attack, December 2012 to early February 2013. The spear phishing used an attachment called Christmas_Card.app.zip. (Remember, the attack started in December.)
So, that brings us to this bit of advice for those of you who might be targets.
This is the default "Gatekeeper" security setting:
Mac App Store and identified developers
This is the setting that you want, unless you're actively installing software:
Mac App Store
This is the prompt that results when OSX/KitM attempts to install with the stricter setting:
If you're running OS X Mountain Lion or Lion v10.7.5 — adjust your settings as an extra layer of precaution.
LulzSec – the rockband of hacker groups – had three of their six members sentenced today in London.
LulzSec made headlines during their "50 days of Lulz" in May-June 2011, during which they attacked Fox, PBS, Sony, Nintendo, Sega, Minecraft, Infragard, NHS, US Senate, SOCA and CIA. They also recorded and published a conference call between US and European law enforcement officials, discussing police tactics against LulzSec.
LulzSec was different from most other attackers, as they weren't doing their attacks to make money or to protest. They did it for Teh Lulz. Also, they had no sense of self-preservation, which led to taking them down.
The Oslo Freedom Forum is an annual event "exploring how best to challenge authoritarianism and promote free and open societies." This year's conference (which took place May 13-15) had a workshop for freedom of speech activists on how to secure their devices against government monitoring. During the workshop, Jacob Appelbaum actually discovered a new and previously unknown backdoor on an African activist's Mac.
Our Mac analyst (Brod) is currently investigating the sample.
