Blackhat 2010 Presentation “Oracle, Interrupted: Stealing Sessions and Credentials” online
18 Apr 2010 von Alexander Kornbrust.
The Blackhat Europe 2010 “Oracle, Interrupted: Stealing Sessions and Credentials” (presentation, whitepaper) of Steve Ocepek and Wendel G. Henrique are online. An interview with Steve about the talk can be found here.
As mentioned in a previous blog post this talk shows how to intercept unencrypted (=default) TNS connections and inject statements into a running session. Steve and Wendel will soon release 2 tools Vamp and thicknet.
I will try to present these tools at the DOAG Expertenseminar in Berlin.
A good summary of the talk can be found at Peter Van Eeckhoutten’s blog.

New fast Oracle DES password cracker OPS_SSE2
15 Apr 2010 von Alexander Kornbrust.
Dennis Yurichev has released a new password cracker (brute-force) called ops_sse2 for Oracle DES passwords. This password cracker is the fastest brute force cracker for Oracle DES passwords and approx. 3 times faster than woraauthbf from Laszlo Toth.
Here a quick comparision on my Quad2Core (2.4 GHz):
Password length (8 character) (only characters) can be cracked in approx 3 hours. For numbers and characters it takes approx. 2.5 days for a single password.
Impressive work…

Python Source for PLSQL Unwrapper posted
13 Apr 2010 von Alexander Kornbrust.
Niels Teusink has posted a Python script to unwrap PL/SQL code (10g+ only). This python script can unwrap code on the command line.
More details are available in the blog entry of Niels.
This is a better solution than the online unwrapper.

Man-in-the-Middle attacks at upcoming Black Hat Europe
12 Apr 2010 von Alexander Kornbrust.
Wendel Guglielmetti Henrique and Steve Ocepek will demonstrate at the upcoming Black Hat Europe 2010 in Barcelona (14-15 April) how to steal credentials by downgrading authentication mechanisms as well as overtaking existing user sessions. They will also show their thicknet tool which will be available after the conference.
This sounds similar to Laszlo work on downgrading JDBC. But I had already a chance to review their presentation so I know it is different.
More information after their presentation.

László Tóth published his Hacktivity presentation & a tool called pytnsproxy
24 Mrz 2010 von Alexander Kornbrust.
Today Laszlo sent me an email that he published the English version of his Hacktivity 2009 talk “Oracle authentication” on his webpage. Laszlo was so nice to give me an English private session last year at the Hacktivity in Budapest.
His presentation contains the following topics:
- Introduction
- Oracle native authentication (database)
- Downgrade (Flash Demo)
- Windows authentication
- Module for Squirtle (Flash Demo)
- pytnsproxy (Flash Demo)
I like the part where Laszlo shows how to hijack an Oracle session.
This presentation is a must for everyone interested in the Oracle authentication process.
Well done Laszlo.
