Reset Your Mobile Memory Card Password 2 minutes

We usually set password for our memory card for privacy and security, but the common mistake every one does at least once in out life time forgetting password. If you set password for mobile memory card, then you should be not forget the password. If you does then the only option is to formate your memory card with the help of the card reader and eventually the loss of all your data stored on it. There is a way to break the security wall. If you are a Symbian device lover then no need to worry about the password. You can crack them in few minutes.



In this tutorial I am going to teach you how to reset your memory card password in easy step. Before we start you need to have X-plore (application used to explore your system files and folder even the hidden folders in your device)



Step1: Install X-Plore in your mobile. If you want to download X-Plore search around internet you can download free trail.

Step2: Open your X-plore apps and Press 0(Zero) and check which you have marked the "show the system files"

Step3: Once you done that now go to the following path C:/Sys/Data/Mmcstore

Step4: Once you reached there you need to press "3" under option to set it in the Hex-viewer

Step5: See the third column you will able to see a line of code ! TMSD02G (c??"?x???6?2?6?2?6). Just check the character between the "?" it is your password ie: 62626



Note: If you have not set the password, then you will not able to gain access to C:/Sys/Data

 

single click shutdown by shasha

Did you know that in Windows XP you can shut down your computer from the (eventually DOS prompt) command line box? Moreover, you can do this by clicking your mouse only once.

All you need to do is... right-click on an empty Desktop spot -> select New -> Shortcut -> type shutdown followed by a space, and then enter one or more of the parameters listed below -> click Next -> type a suggestive name for your new shortcut -> finally, click Finish.

This is the Shutdown.exe (located in %systemroot%\System32, usually C:\Windows\System32) syntax:


shutdown [-i|-l|-s|-r|-a] [-f] [-m \\computername] [-t xx] [-c "Text"] [-d[u][p]:xx:yy]

Valid command line switches:

-a = Abort system shutdown in progress ONLY IF the -t xx timeout option was already set to ANY value other than 0. ALL switches except -l and -m are ignored during abort.

-c "Text" = Text comment (case insensitive) to be displayed in the Message area of the System Shutdown window. MUST be enclosed between quotes. Maximum allowed 127 ASCII characters.

-d [u][p]:xx:yy = Reason code for shutdown:
u = User code.
p = Planned shutdown code.
xx = Major reason code. Positive integer number less than 256.
yy = Minor reason code. Positive integer number less than 65536.

-f = Force running applications to close without warning.

-i = Display the shutdown interface (GUI). MUST be the first option!

-l = Log off the current user of the local computer (default action). Can NOT be used with the -m option unless the current user has Sysadmin rights, in which case the -m switch takes precedence.

-m \\computername = Remote/network computer name (most always case sensitive) to log off/restart/shut down. Current user MUST have Sysadmin rights to be allowed to use this switch!

-s = Shut down the local computer.

-r = Shut down and restart (reboot) the local computer.

-t xx = Set shutdown timer to timeout for xx seconds. IF NOT specified defaults to 20 seconds. Allowed values between 0 and 99 seconds. The -a switch is the ONLY one that CAN be used during the timeout period.

NOTES:
The dash (-) in front of these switches can be replaced by a forward slash (/).

Spaces are NOT required to separate the shutdown command from ANY following switches, but ARE required to separate ANY switch from its following parameter(s), if any.
For example:

shutdown -s -c "Shutting down!" -t 3

tells your computer to shutdown after waiting for 3 seconds while the System Shutdown window will display text above in the Message area.

Optional: after you're done creating your customized shortcut for shutdown -> right-click on it -> select Properties -> enter your desired key "combo" in the Shortcut Key box (e.g. Ctrl + Alt + End) -> click OK/Apply.
From now on just left-click on your shutdown shortcut or hit that key combination to turn off/restart/log off your computer.

A simple TCP spoofing attack_shasha

                        A simple TCP spoofing attack


Over the past few years TCP sequence number prediction attacks have become a
real threat against unprotected networks, taking advantage of the inherent
trust relationships present in many network installations.  TCP sequence
number prediction attacks have most commonly been implemented by opening a
series of connections to the target host, and attempting to predict the
sequence number which will be used next.  Many operating systems have
therefore attempted to solve this problem by implementing a method of
generating sequence numbers in unpredictable fashions.  This method does
not solve the problem.

This advisory introduces an alternative method of obtaining the initial
sequence number from some common trusted services.  The attack presented here
does not require the attacker to open multiple connections, or flood a port
on the trusted host to complete the attack.  The only requirement is that
source routed packets can be injected into the target network with fake
source addresses.

This advisory assumes that the reader already has an understanding of how
TCP sequence number prediction attacks are implemented.

The impact of this advisory is greatly diminished due to the large number of
organizations which block source routed packets and packets with addresses
inside of their networks.  Therefore we present the information as more of
a 'heads up' message for the technically inclined, and to re-iterate that
the randomization of TCP sequence numbers is not an effective solution
against this attack.


Technical Details
~~~~~~~~~~~~~~~~~

The problem occurs when particular network daemons accept connections
with source routing enabled, and proceed to disable any source routing
options on the connection.  The connection is allowed to continue, however
the reverse route is no longer used.  An example attack can launched against
the in.rshd daemon, which on most systems will retrieve the socket options
via getsockopt() and then turn off any dangerous options via setsockopt().

An example attack follows.

Host A is the trusted host
Host B is the target host
Host C is the attacker

Host C initiates a source routed connection to in.rshd on host B, pretending
to be host A.

Host C spoofing Host A         <SYN>    -->  Host B in.rshd

Host B receives the initial SYN packet, creates a new PCB (protocol
control block) and associates the route with the PCB.  Host B responds,
using the reverse route, sending back a SYN/ACK with the sequence number.

Host C spoofing Host A  <--  <SYN/ACK>       Host B in.rshd

Host C responds, still spoofing host A, acknowledging the sequence number.
Source routing options are not required on this packet.

Host C spoofing Host A         <ACK>    -->  Host B in.rshd

We now have an established connection, the accept() call completes, and
control is now passed to the in.rshd daemon.  The daemon now does IP
options checking and determines that we have initiated a source routed
connection.  The daemon now turns off this option, and any packets sent
thereafter will be sent to the real host A, no longer using the reverse
route which we have specified.  Normally this would be safe, however the
attacking host now knows what the next sequence number will be.  Knowing
this sequence number, we can now send a spoofed packet without the source
routing options enabled, pretending to originate from Host A, and our
command will be executed.

In some conditions the flooding of a port on the real host A is required
if larger ammounts of data are sent, to prevent the real host A from
responding with an RST.  This is not required in most cases when performing
this attack against in.rshd due to the small ammount of data transmitted.

It should be noted that the sequence number is obtained before accept()
has returned and that this cannot be prevented without turning off source
routing in the kernel.

As a side note, we're very lucky that TCP only associates a source route with
a PCB when the initial SYN is received.  If it accepted and changed the ip
options at any point during a connection, more exotic attacks may be possible.
These could include hijacking connections across the internet without playing
a man in the middle attack and being able to bypass IP options checking
imposed by daemons using getsockopt().  Luckily *BSD based TCP/IP stacks will
not do this, however it would be interesting to examine other implementations.

Impact
~~~~~~

The impact of this attack is similar to the more complex TCP sequence
number prediction attack, yet it involves fewer steps, and does not require
us to 'guess' the sequence number.  This allows an attacker to execute
arbitrary commands as root, depending on the configuration of the target
system.  It is required that trust is present here, as an example, the use
of .rhosts or hosts.equiv files.


Solutions
~~~~~~~~~

The ideal solution to this problem is to have any services which rely on
IP based authentication drop the connection completely when initially
detecting that source routed options are present.  Network administrators
and users can take precautions to prevent users outside of their network
from taking advantage of this problem.  The solutions are hopefully already
either implemented or being implemented.

1. Block any source routed connections into your networks
2. Block any packets with internal based address from entering your network.

Network administrators should be aware that these attacks can easily be
launched from behind filtering routers and firewalls.  Internet service
providers and corporations should ensure that internal users cannot launch
the described attacks.  The precautions suggested above should be implemented
to protect internal networks.

Example code to correctly process source routed packets is presented here
as an example.  Please let us know if there are any problems with it.
This code has been tested on BSD based operating systems.

        u_char optbuf[BUFSIZ/3];
        int optsize = sizeof(optbuf), ipproto, i;
        struct protoent *ip;

        if ((ip = getprotobyname("ip")) != NULL)
                ipproto = ip->p_proto;
        else
                ipproto = IPPROTO_IP;
        if (!getsockopt(0, ipproto, IP_OPTIONS, (char *)optbuf, &optsize) &&
            optsize != 0) {
                for (i = 0; i < optsize; ) {
                        u_char c = optbuf[i];
                        if (c == IPOPT_LSRR || c == IPOPT_SSRR)
                                exit(1);
                        if (c == IPOPT_EOL)
                                break;
                        i += (c == IPOPT_NOP) ? 1 : optbuf[i+1];
                }
        }


One critical concern is in the case where TCP wrappers are being used.  If
a user is relying on TCP wrappers, the above fix should be incorporated into
fix_options.c.  The problem being that TCP wrappers itself does not close
the connection, however removes the options via setsockopt().  In this case
when control is passed to in.rshd, it will never see any options present,
and the connection will remain open (even if in.rshd has the above patch
incorporated).  An option to completely drop source routed connections will
hopefully be provided in the next release of TCP wrappers.  The other option
is to undefine KILL_IP_OPTIONS, which appears to be undefined by default.
This passes through IP options and allows the called daemon to handle them
accordingly.


Disabling Source Routing
~~~~~~~~~~~~~~~~~~~~~~~~

We believe the following information to be accurate, however it is not
guaranteed.

--- Cisco

To have the router discard any datagram containing an IP source route option
issue the following command:

no ip source-route

This is a global configuration option.


--- NetBSD

Versions of NetBSD prior to 1.2 did not provide the capability for disabling
source routing.  Other versions ship with source routing ENABLED by default.
We do not know of a way to prevent NetBSD from accepting source routed packets.
NetBSD systems, however, can be configured to prevent the forwarding of packets
when acting as a gateway.

To determine whether forwarding of source routed packets is enabled,
issue the following command:

# sysctl net.inet.ip.forwarding
# sysctl net.inet.ip.forwsrcrt

The response will be either 0 or 1, 0 meaning off, and 1 meaning it is on.

Forwarding of source routed packets can be turned off via:

# sysctl -w net.inet.ip.forwsrcrt=0

Forwarding of all packets in general can turned off via:

# sysctl -w net.inet.ip.forwarding=0


--- BSD/OS

BSDI has made a patch availible for rshd, rlogind, tcpd and nfsd.  This
patch is availible at:

ftp://ftp.bsdi.com/bsdi/patches/patches-2.1

OR via their patches email server <patches@bsdi.com>

The patch number is
U210-037 (normal version)
D210-037 (domestic version for sites running kerberized version)


BSD/OS 2.1 has source routing disabled by default

Previous versions ship with source routing ENABLED by default.  As far as
we know, BSD/OS cannot be configured to drop source routed packets destined
for itself, however can be configured to prevent the forwarding of such
packets when acting as a gateway.

To determine whether forwarding of source routed packets is enabled,
issue the following command:

# sysctl net.inet.ip.forwarding
# sysctl net.inet.ip.forwsrcrt

The response will be either 0 or 1, 0 meaning off, and 1 meaning it is on.

Forwarding of source routed packets can be turned off via:

# sysctl -w net.inet.ip.forwsrcrt=0

Forwarding of all packets in general can turned off via:

# sysctl -w net.inet.ip.forwarding=0


--- OpenBSD

Ships with source routing turned off by default.  To determine whether source
routing is enabled, the following command can be issued:

# sysctl net.inet.ip.sourceroute

The response will be either 0 or 1, 0 meaning that source routing is off,
and 1 meaning it is on.  If source routing has been turned on, turn off via:

# sysctl -w net.inet.ip.sourceroute=0

This will prevent OpenBSD from forwarding and accepting any source routed
packets.


--- FreeBSD

Ships with source routing turned off by default.  To determine whether source
routing is enabled, the following command can be issued:

# sysctl net.inet.ip.sourceroute

The response will be either 0 or 1, 0 meaning that source routing is off,
and 1 meaning it is on.  If source routing has been turned on, turn off via:

# sysctl -w net.inet.ip.sourceroute=0


--- Linux

Linux by default has source routing disabled in the kernel.


--- Solaris 2.x

Ships with source routing enabled by default.  Solaris 2.5.1 is one of the
few commercial operating systems that does have unpredictable sequence
numbers, which does not help in this attack.

We know of no method to prevent Solaris from accepting source routed
connections, however, Solaris systems acting as gateways can be prevented
from forwarding any source routed packets via the following commands:

# ndd -set /dev/ip ip_forward_src_routed 0

You can prevent forwarding of all packets via:

# ndd -set /dev/ip ip_forwarding 0

These commands can be added to /etc/rc2.d/S69inet to take effect at bootup.


--- SunOS 4.x

We know of no method to prevent SunOS from accepting source routed
connections, however a patch is availible to prevent SunOS systems from
forwarding source routed packets.

This patch is availible at:

ftp://ftp.secnet.com/pub/patches/source-routing-patch.tar.gz

To configure SunOS to prevent forwarding of all packets, the following
command can be issued:

# echo "ip_forwarding/w 0" | adb -k -w /vmunix /dev/mem
# echo "ip_forwarding?w 0" | adb -k -w /vmunix /dev/mem

The first command turns off packet forwarding in /dev/mem, the second in
/vmunix.


--- HP-UX

HP-UX does not appear to have options for configuring an HP-UX system to
prevent accepting or forwarding of source routed packets.  HP-UX has IP
forwarding turned on by default and should be turned off if acting as a
firewall.  To determine whether IP forwarding is currently on, the following
command can be issued:

# adb /hp-ux
ipforwarding?X      <- user input
ipforwarding:
ipforwarding: 1
#

A response of 1 indicates IP forwarding is ON, 0 indicates off.  HP-UX can
be configured to prevent the forwarding of any packets via the following
commands:

# adb -w /hp-ux /dev/kmem
ipforwarding/W 0
ipforwarding?W 0
^D
#

--- AIX

AIX cannot be configured to discard source routed packets destined for itself,
however can be configured to prevent the forwarding of source routed packets.
IP forwarding and forwarding of source routed packets specifically can be
turned off under AIX via the following commands:

To turn off forwarding of all packets:

# /usr/sbin/no -o ipforwarding=0

To turn off forwarding of source routed packets:

# /usr/sbin/no -o nonlocsrcroute=0

Note that these commands should be added to /etc/rc.net



If shutting off source routing is not possible and you are still using
services which rely on IP address authentication, they should be disabled
immediately (in.rshd, in.rlogind).  in.rlogind is safe if .rhosts and
/etc/hosts.equiv are not used.
