Earlier in February 2013, FireEye announced the discovery of a new malware that exploited a 0-day vulnerability in Adobe Reader. Now, we announce another, as yet unknown malware that exploits the same Adobe Reader vulnerability (CVE-2013-0640).
This new malware was named Miniduke by Kaspersky Labs with whom we carried out its first analysis. Our participation […]
You remember the Duqu font related exploit and shell code in the dropper? Yes, that’s the exploit that was recently used in many exploit kits.
First of all, this is a kernel level exploit, it should be kept in mind while checking code.
The original dropper had a decryptor for the stage1 of shell […]
Some time ago, we rechecked some Stuxnet code. Guess what have we learned: Kasperksy already published Flame-Stuxnet relationship, but on the encryption level, there is another similarity. In fact, this was found by Norman back in June , but they compared with soapr32’s encryption which is slightly more different than 4069.dll’s encryption E2.
Just a short blog entry to save this info for the history.
We investigated originally two different pieces of duqu payload. One contained resource 302 with a compressed .zdata section, the other contained the to-be-injected code without compression. The injector-loader is the same for the two versions, then how does it find if .zdata should […]

SPE/MiniFlame contains the same “main” encryption alg from ver 4.00-5.00
It looks like this:
.text:10007DDE Decrypt_str_10007DDE proc near ; CODE XREF: sub_10001223+5p
.text:10007DDE ; sub_10001223+16p …
.text:10007DDE arg_0 = dword ptr 4
.text:10007DDE mov ecx, [esp+arg_0]
.text:10007DE2 push esi
.text:10007DE3 cmp byte ptr [ecx+0Ch], 42h
It seems Gauss samples already started to float around, so some more info on Palida is not a surprise anymore.
Palida Narrow header info:
‘head’ Table – Font Header
Size = 54 bytes (expecting 54 bytes)
‘head’ version: 1.0
flags: 0x001B- baseline(y)=0 […]
As you all know, Kaspersky Lab has just published a detailed tech report of the latest state-sponsored targeted threat named Gauss.
So the story of Stuxnet, Duqu (found and named by us, CrySyS Lab ), Flame (yes, we had a detailed tech report on that, but we called it […]

Our latest post on 15/07 was about a trojan dropped by some Java applet that contains some Java exploit.
The dropped trojan is a fake antivirus software, here is some screenshot of it:
We found that the exploit in use was CVE-2012-1723, which is analyzed […]
