CVE-2009-3867 + CVE-2008-5353 JAVA low detection obfuscated malware

All the credit for this post goes to TomU (c-apt-ure.blogspot.com) .

Also, many thanks to Donato "ratsoul" Ferrante (inReverse.net) for his help with the identification.

FILE 1

CVE-2008-5353 The Java Runtime Environment (JRE) for Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier does not properly enforce context of ZoneInfo objects during deserialization, which allows remote attackers to run untrusted applets and applications in a privileged context, as demonstrated by "deserializing Calendar objects".

FILE 2

CVE-2009-3867 Stack-based buffer overflow in the HsbParser.getSoundBank function in Sun Java SE in JDK and JRE 5.0 before Update 22, JDK and JRE 6 before Update 17, SDK and JRE 1.3.x before 1.3.1_27, and SDK and JRE 1.4.x before 1.4.2_24 allows remote attackers to execute arbitrary code via a long file: URL in an argument, aka Bug Id 6854303.

Low detection is due to obfuscation

Low detection is due to obfuscation

Until recently, the detection was 0/41

Tom pointed out that the traffic/ URL patterns are similar to those described here Webseite des US-Finanzministeriums gehackt,  where the malware loaded was from Eleonore v.1.3.2. Eleonore 1.4.1 does not contain CVE-2008-5353,  which makes us think these files could be indeed from Eleonore 1.3.2 Another possibility is Phoenix 2.0, which contains the same java exploits (if you figure out which exploit pack is hanging on that IP, let me know)
