Information Security and Assurance : (I.S.A)

Computer security is a branch of technology known as information security as applied to computers. The objective of computer security varies and can include protection of information from theft or corruption, or the preservation of availability, as defined in the security policy.
Computer security imposes requirements on computers that are different from most system requirements because they often take the form of constraints on what computers are not supposed to do. This makes computer security particularly challenging because it is hard enough just to make computer programs do everything they are designed to do correctly. Furthermore, negative requirements are deceptively complicated to satisfy and require exhaustive testing to verify, which is impractical for most computer programs. Computer security provides a technical strategy to convert negative requirements to positive enforceable rules. For this reason, computer security is often more technical and mathematical than some computer science fields.[citation needed]
Typical approaches to improving computer security (in approximate order of strength) can include the following:
Physically limit access to computers to only those who will not compromise security. Hardware mechanisms that impose rules on computer programs, thus avoiding depending on computer programs for computer security. Operating system mechanisms that impose rules on programs to avoid trusting computer programs. Programming strategies to make computer programs dependable and resist subversion.

Overview

The SANS Institute maintains a list of the "Top 10 Software Vulnerabilities." At the current time, over half of these vulnerabilities are exploitable by Buffer Overflow attacks, making this class of attack one of the most common and most dangerous weapon used by malicious attackers. This is the first book specifically aimed at detecting, exploiting, and preventing the most common and dangerous attacks.

Buffer overflows make up one of the largest collections of vulnerabilities in existence; And a large percentage of possible remote exploits are of the overflow variety. Almost all of the most devastating computer attacks to hit the Internet in recent years including SQL Slammer, Blaster, and I Love You attacks. If executed properly, an overflow vulnerability will allow an attacker to run arbitrary code on the victims machine with the equivalent rights of whichever process was overflowed. This is often used to provide a remote shell onto the victim machine, which can be used for further exploitation.

A buffer overflow is an unexpected behavior that exists in certain programming languages. This book provides specific, real code examples on exploiting buffer overflow attacks from a hacker's perspective and defending against these attacks for the software developer.

This is quite a lame virus but anyway still many computers still infected with this virus. So I will write a tutorial to help people to remove this pest.

Characteristics

Step 1 - Enable Registry Editor and folder option

Download Washer here. Enable back your registry editor and folder options by using washer.

- If the virus attacked your computer, there will be a check at the Disable Regedit, Hide Find and Hide Folder Option check button.
- Leave the check button and straightaway click the repair registry button and in just a few second, you can access back your registry, search and folder options.
- If this doesn't work, try it again or ask someone to help you.

Step 2 - Remove the virus link in registry

First open the registry editor by Start > Run and type regedit and press enter. Go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentUser\Run and delete the WindowsMSN key at the right hand-side.

Then go to HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam\MUICache\ and delete the C:\WINDOWS\system32\Flash.10.exe key at right hand side.

Then go to HKEY_CURRENT_USER\Software\Microsoft\WindowsNT\
CurrentVersion\Windows\ and delete the load key at the right.

Then, go to HKEY_USERS\S-1-5-21-2000478354-2025429265-839522115-1003\
Software\Microsoft\Windows\ShellNoRoam\MUICache

and delete the C:\WINDOWS\system32\Flash.10.exe

and last go to HKEY_USERS\S-1-5-21-2000478354-2025429265-839522115-1003\
Software\Microsoft\WindowsNT\CurrentVersion\Windows\
and delete load key.

If your are tired to find the key, just press F3 and typed flash.10 and press again F3 to keep search.

After that, restart your computer.


Step 3 - delete the virus file

After restart your computer, make sure the virus is not run anymore. Open your task manager and if Flash.10 and Macromedia.10 is not in the process list, it is safe for you to delete the virus file. If not, repeat step 2.

Before delete the virus, you need to configure your Folder Options first. Open My Computer, click Tools menu and choose Folder Options. If Folder Options did not appear, repeat step 1.

Now Change the setting as my folder options on the picture below. Changes are on Show hidden file, Hide protected operating system file and Hide extension for known files. Click Ok.

Go to C:\Program Files\Common Files\Microsoft Shared\ and delete Macromedia.10.exe

Now, open C:\Program Files\Common Files\Microsoft Shared\DAO\ and delete file MSN.msn. The virus try to spoof by using MSN logo and name.

Then, go to C:\WINDOWS\System32\ . Right Click, choose Arrange Icon By > Modified. Then scroll to the last row and try to find Flash.10.exe, cmd.com, dxdiag.com, JambanMu.com, msconfig.com, ping.com and regedit.com. Delete the file. Remember, just delete the listed file only!!

Then, delete the virus in your USB drive. Delete only Flash Jokes.exe, Autorun.inf, Flash.10.Setup.exe and Scanner.exe

Now restart your computer. Hopefully your computer will be okay.
