The Tel Aviv University Security Forum - meeting #11 - 8/5/05
From: Gadi Evron <ge () linuxbox org>
Date: Mon, 02 May 2005 19:47:07 +0400
The next, non-commercial, technological Security Forum will take place
on Sunday, the 8th of May, 2005, at Tel Aviv University's Lev
17:45 - Gathering - hot and cold drinks will be served.
18:00 - Yaniv Shaked.
Lecture: Cracking the Bluetooth PIN.
This paper/lecture describes the implementation of an attack on the
Bluetooth security mechanism. Specifically, we describe a passive
attack, in which an attacker can find the PIN used during the pairing
process. We then describe the cracking speed we can achieve through
three optimizations methods. Our fastest optimization employs an
algebraic representation of a central cryptographic primitive (SAFER+)
used in Bluetooth. Our results show that a 4-digit PIN can be cracked
in less than 0.3 seconds on an old Pentium III 450MHz computer, and in
0.06 seconds on a Pentium IV 3Ghz HT computer.
In addition, We present another attack that is effective when used in
conjunction with the first attack. This attack causes devices
communicating to repeat the pairing process.
19:00 - We will break for a short recess, as well as for
refreshments and networking between members - hot and cold
drinks will be served.
19:20 - Gadi Evron.
Lecture: Botnets and drone armies.
Level: Dependant on the audience.
In this lecture we will introduce the subject of botnets (drone
armies). Thousands and millions of compromised machines, gathered into
a centralized force for directed malicious activity.
We will go into any relevant material ranging from detection to
construction depending on audience interest during the lecture.
Hot and cold drinks will be freely available.
Attendance is free.
