Posted by brainfoldb4u on January 18, 2010

You might be looking for a way to try out Ubuntu Linux but don’t like the idea of creating a partition, using a slow live CD, or don’t have enough resources to run a virtual machine. Today we take a look at using the Wubi installer to get Ubuntu running on your computer with very little effort.

Wubi is an officially supported Ubuntu installer that allows Windows users to easily get started in the Linux realm. Using Wubi to install Ubuntu is a similar process you’d use to install any other software program in Windows. It saves you the hassle of creating another partition or creating a VM. Wubi has been around for a few years now, and official version have been included on the Ubuntu Live CD since 8.04 “Hardy Heron”. We’ll take a look at installing Wubi from the Ubuntu Live CD and also downloading Wubi.exe separately and installing Ubuntu.

Android's malicious apps

Posted by brainfoldb4u on January 11, 2010

Android, a Linux based mobile operating system intially developed by Android Inc., and later purchased by Google. Google recently released their new mobile “Nexus One”with android OS. Google allows developers to write managed code in the Java language, controlling the device via Google developed Java libraries.

So far in 2010 Google android has proven to be a hot topic with increasing popularity. As it popularity increases it becomes the target for hackers and malware writers to explore its security.  As per kaspersky, “2010 promises to be a difficult time for iPhone and Android users,”.

As per kaspersky press release

An increase in attacks on iPhone and Android mobile platforms. 2010 promises to be a difficult time for iPhone and Android users. The first malicious programs for these mobile platforms appeared in 2009, a sure sign that they have aroused the interest of cybercriminals. The only iPhone users currently at risk are those with compromised devices; however the same is not true for Android users who are all vulnerable to attack. The increasing popularity of mobile phones running the Android OS combined with a lack of effective checks to ensure third-party software applications are secure, will lead to a number of high-profile malware outbreaks.

They also made five other predictions on greatest threats and new attack vector and they are

  • A rise in attacks originating from file sharing networks. This year, we will see a shift in the types of attacks on users, from attacks via websites and applications toward attacks originating from file sharing networks.
  • An increase in mass malware epidemics via P2P networks. In 2009 a series of mass malware epidemics has been “supported” by malicious files that are spread via file sharing networks. This method has been used to spread notorious threats such as TDSS and Virut as well as the first backdoor for Mac OS X. In 2010, we expect to see a significant increase in these types of incidents on P2P networks.
  • Continuous competition for traffic from cybercriminals. The modern cybercriminal world is making more and more of an effort to legalize itself and there are lots of ways to earn money online using the huge amount of traffic that can be generated by botnets. In the future, we foresee the emergence of more “grey” schemes in the botnet services market. These so-called “partner programs” enable botnet owners to make a profit from activities such as sending spam, performing denial of service (DoS) attacks or distributing malware without committing an explicit crime.
  • A decline in fake anti-virus programs. The decline in gaming Trojans witnessed in 2009 is likely to be repeated for fake anti-virus programs in 2010. Conficker installed a rogue anti-virus program on infected computers. The fake anti-virus market has now been saturated and the profits for cybercriminals have fallen. Additionally, this kind of activity is now being closely monitored by both IT security companies and law enforcement agencies, making it increasingly difficult to distribute fake anti-virus programs.
  • An interest in attacking Google Wave. When it comes to attacks on web services, Google Wave looks like it will be making all the headlines in 2010. Attacks on this new Google service will no doubt follow the usual pattern: first, the sending of spam, followed by phishing attacks, then the exploiting of vulnerabilities and the spreading of malware.

Users of mobile devices with Android software may have noticed several applications available for download in the Android Marketplace. If you see any applications provided by the user Droid09, please do not download these applications. Android applications provided by Droid09 are fraudulent. Please remove any applications by Droid09 from your mobile device and contact your mobile provider to evaluate whether any other applications or information stored on your mobile device have been compromised.”

Open Source

Posted by brainfoldb4u on December 25, 2009

Open source

Open source is a development method and the creative practice of appropriation and free sharing of information/invention.  This method enhances the power of distributed or autonomous behavior.  This way improves the transparency and promises better quality, flexibility, reliability, and availability. Good part is our standards body are maintaining this open source concepts for good of the community. This way makes any one can be a developer, reviewer or even a hacker (both in better and bitter way).

There are numerous open source projects like source-forge, open office, Linux, Ubuntu, ruby and many others available to us and wonder how many of us know about their existence and value they bring in comparison to their costly counterparts.  It became my interest to explore open source ad make reader aware of it.  Thus i am going to use this space in my page to talk about the source projects, their benefits and unique features they bring along …

Open source web

In general Open source software is whose source code is freely published and made available to any one and they can choose to edit, discover something new or even redistribute it without paying royalties.  Though said, it is not an easy task , it requires dedication ,involvement and community cooperation.  Few of those open source products are:

  • Linux:  Open source operating system based on Unix
  • Apache:  HTTP web server
  • MySQL: Most popular open source database.
  • Tomcat: provides pure java HTTP web server environment for Java code to run.
  • Eclipse: Open source software framework for rich client applications.
  • Mozilla Firefox: Worthy IE competent with rich plugins and customizable browser.
  • Ruby on Rail: Full stacked, web application framework optimized for building and publishing application for free.
  • Open Office.org:  Very useful MS office counterpart with built-in word, spreadsheet, power point and many..
  • MediaWiki: Knowledge base and the software that runs Wikipedia
  • Drupal/Joomla: Open source content management systems
  • Coffee Cup: Very useful HTML/CSS editor and website content developer.
  • PHP/Perl/Java: Handy scripting or programming languages that available for anyone to learn and master.
