Pyrit -WPA/WPA2-PSK Epic Fail-

Pyrit allows to create massive databases, pre-computing part of the IEEE 802.11 WPA/WPA2-PSK authentication phase in a space-time-tradeoff. Exploiting the computational power of Many-Core- and other platforms through ATI-StreamNvidia CUDA and OpenCL, it is currently by far the most powerful attack against one of the world's most used security-protocols.

WPA/WPA2-PSK is a subset of IEEE 802.11 WPA/WPA2 that skips the complex task of key distribution and client authentication by assigning every participating party the same pre shared key. This master key is derived from a password which the administrating user has to pre-configure e.g. on his laptop and the Access Point. When the laptop creates a connection to the Access Point, a new session key is derived from themaster key to encrypt and authenticate following traffic. The "shortcut" of using a single master key instead of per-user keys eases deployment of WPA/WPA2-protected networks for home- and small-office-use at the cost of making the protocol vulnerable to brute-force-attacks against it's key negotiation phase; it allows to ultimately reveal the password that protects the network. This vulnerability has to be considered exceptionally disastrous as the protocol allows much of the key derivation to be pre-computed, making simple brute-force-attacks even more alluring to the attacker. For more background see this article on the project's blog.

R77 is now available!

It seems to be the best one ever.

What's New in R77

New Threat Emulation Software Blade

The new Threat Emulation Software Blade blocks attacks which cannot be detected by signatures. It opens inspected files inside secure emulation environments to detect malicious behavior. It can be deployed as a cloud service or as a private (local) cloud.

New Check Point Compliance Blade

This new Software Blade analyzes your environment for compliance with major regulations and international standards. Check Point Compliance Blade generates detailed reports, with best practice recommendations taken from the large Check Point library. Check Point Compliance Blade sends alerts for policy changes that can affect compliance.

Sending Syslog flow to an External Log Server

Dear Checkpoint Fellows and Followers,

Syslog data is possible to be sent as shown in sk33423, however only from physical boxes.

If you have VSX infrastructure, it is not possible to send syslogs of each vsx customer to another syslog server. All and all..


Checkpoint R77

Very excited to test the new blades! :)

Check Point R75.47 Released!

The release notes and the resolved issues, it’s mainly a maintenance or bug fix version.

There are a lot of fixed bugs.

It would be good to install the version firstly within the test environment, and then get it into production a.s.a.p.

License Info Tool / Checkpoint

License Tool for Checkpoint. I found it pretty useful actually as the license issues seem complicated most often. My Products > License Info Tool.

Fortinet Upgrade Procedures

The upgrade processes have usually been a issue with Check Point. However, it is unbelievably easy for security vendor Fortinet (even in the cluster env.)

- .out file is downloaded from the support site.
- it is uploaded through GUI.

then, all process goes on automatically; firstly the active member is upgraded with losing 4 - 6 ping packets, and then 2-3 ping lost while  upgrading the second member.

I suppose the reason is truly the architecture difference behind these boxes.

Network Troubleshooting - Cisco Packet Flow

To be or not to be.
Incoming or Outgoing Packets, sometimes understanding these two subjects are very vital in troubleshooting process.

ip access-list  extended gre-debug-out
permit gre any any log // optional 
permit ip any any log

ip access-list  extended gre-debug-in
permit gre any any log // optional
permit ip any any log

interface GigabitEthernet0/1
ip access-group gre-debug-in in
ip access-group gre-debug-out out

Here it is; 

show ip access-list gre-debug-in

show ip access-list gre-debug-out out

believe me you will like the result..
