You might have been struck by the Curse of Silence bug that has been floating around for a while, and has been recently made public at the Chaos Computer Club. When a suitably vulnerable Nokia phone receives an SMS which has been crafted in the right way it is struck deaf and becomes unable to receive SMS text messages without a factory reset: type #7370# to do this, but you’ll lose everything.

And because MMS is triggered by SMS that’s killed too.

How does the bug work? Text messaging has lots of buried features.There are various types of text message such as those which update your internet settings or make a voicemail icon appear. Other types include paging systems, fax and email. You can also, if you know what you are doing, fake sending an email that by putting characters with those values in the right place in a message. For email the special type is “SMS and Internet Electronic Mail interworking”. One of the things which differentiates an email from a text message is you have a “from” address as well as a body. To allow for this the standard uses a space between the “from” and the message.

To make all this a bit friendlier, Nokia phones using Series 60 version 2.6 or newer scan the bit before the space to look for what might be an email address – something with an @ in it. Clearly this seemed to be a good idea to the right developers at the time, but it’s a minor feature and didn’t justify significant testing. Unfortunately if the email address is longer than 32 characters, Series 60 versions 2.6, 2.8, 3.0 and 3.1 phones go into the kind of strop most families experience at Christmas and fail to communicate. Phones with version 2.6 or 3.0 don’t shrug their shoulders or slam doors. In fact they don’t give any indication that anything is wrong at all. A factory reset fixes this but will take all your personal data including the games high scores you spent so long on over Christmas. If you back your phone up after you’ve been attacked when you restore the data you restore the problem.

It’s a bit harder to deafen a version 2.8 or 3.1 phone. These need to receive 11 maliciously crafted SMS text messages and then they say that there is not enough memory to receive further messages, and something should be deleted. These phones will seem to work if you soft reset them, but the next text message of over 160 characters will kill everything again.

The work on tracking this down has been done by Tobias Engel, and was presented to the Chaos Computer Club.

FileStream Class Exposes a Stream around a file, supporting both synchronous and asynchronous read and write operations.

Now, what is is FileStream Seek() Method?

FileStream Seek() Method Sets the current position of this stream to the given value.

[ Read more: Here ]

Below we are going to see some code examples to understand better.

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using System.IO;

namespace WindowsFormsApplication1

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

FileStream fichero = new FileStream(“C:\\banner.txt”, FileMode.Create);

char a;

label1.Text = “”;

for (int i = 0; i < 10; i++)

{

fichero.WriteByte((byte)(‘1′ + i));

}

fichero.Seek(0, SeekOrigin.Begin);

a = (char)fichero.ReadByte();

label1.Text += “The first value is” + a + “\n”;

fichero.Seek(7, SeekOrigin.Begin);

a = (char)fichero.ReadByte();

label1.Text += “and the 7th is “ + a + “\n”;

fichero.Close();

}

}

}

In this example we are using Seek() method to display the specified value in Label1’s text property. The first method displays the number ‘1′ and the 7th is displaying number ‘8′. If yoy check your .txt file you will find there something like this : “123456789:” because FileMode.Create creates new file and open it for read and write, if the file exists overwrite it.

According to a report by Security Tracker, all versions of Windows Media Player, including the latest version, 11, have a security related vulnerability. The problem is an integer overflow when playing WAV, SND or MIDI files, which can allow an attacker to execute arbitrary code with the privileges of the user…”

From Security And The Net: “As more people are becoming concerned about their online privacy, the use of tools to protect that privacy such as Tor and Privoxy is getting more common. One of the main features that these offer are “hiding” your IP address; privoxy by offering the option to send all your traffic through a proxy server, and Tor by even more advanced routing…”.
