The third annual Pwn2Own security competition that was held at the CanSecWest conference in Vancouver, Canada has come to an end on 20th March 2009, i.e. Friday and revealed the weaknesses and loopholes of all the popular web browsers. This competition was intended to offer the white hat hackers a chance to crack the codes of popular web browsers including Mozilla Firefox, Internet Explorer and Apple Safari and the codes of popular smartphone operating systems.

The results are quite amazing, something that wasn’t expected. The Google Chrome and all the smartphones remained un-cracked but the Apple Safari, Internet Explorer and Mozilla Firefox were easily hacked multiple times. Apple Safari was hacked by Charlie Miller in just a couple of seconds. This was followed by a 25 year old computer science student named Nils who demonstrated the vulnerabilities of Safari, Internet Explorer 8 and Firefox.

The contestants also tried their tricks on Google Chrome browser and BlackBerry, Android, iPhone, Symbian and Windows Mobile smartphones but failed to break into the codes of these applications. According to the TippingPoint Technologies, the sponsor of the event, the Apple iPhone 3G could be hacked using one of the Safari exploits that was already used but according to the contest rules the same bug cannot be used twice.

The results clearly reveal that the smartphone OSes are far more secure than web browsers, except Google Chrome. This definitely brings the Chrome on the top of other web browsers and is expected to outshine its rivalries in near future in terms of market share, popularity and reliability.

Kido is the latest threat that is infecting Windows systems all over the world. It is also known as Conficker and Downadup and has infected (in fact destroyed) more than nine million Windows systems up until now. Kido is a powerful worm that directly affects the system’s kernel, registry and Windows files and replicates at a fast pace. The reason why this worm is dangerous is that it gives the spammers full control over the infected PC and lets them trace sensitive information such as credit card number, passwords, online banking transaction etc.

Fortunately the Microsoft Corporation has got a solution to both prevent this worm from entering into the PC and remove it from any infected system. The company has launched new security patches that proactively respond to this threat. Once installed in an uninfected PC the security patch will not allow the Kido to do its malicious tasks. The company has also launched a malicious software removal tool that should be used in case the Kido has already infected a Windows system. So if you are unfortunate enough to receive Kido then it won’t allow you to download the security patch. You have to remove it first via removal tool and then install the security patch. The solution is of course to purchase a computer running either Linux or the latest Mac OS, like the Apple MacBook Pro MB71B/A. However, if you have been using the Safari on Windows version on your Windows PC, and are already infected, then the only solution is to follow the aforementioned steps.

The company says, “If your computer or environment is impacted by this malware, you may want to run the malicious software removal tool to help disinfect it. The first step would be to install the update on all your computers and replace passwords of network shares with stronger ones. Then use the malicious software removal tool to remove the worm from infected computers. Infected computers may not be able to access Windows Update and therefore the administrator may need first to download the tool using a clean computer, and then distribute it to the other machines.”

Recently a new Worm has emerged as one of the biggest threats for the Windows PCs. It’s been known as Conficker, Kido or Downadup and has infected nine million computers to date. This worm can allow the spammers and phishers to gain total control of the infected PC and trace all the internet activities. It can be used by the cyber criminals as a potential tool to gain access to the user’s confidential information such as credit card number, account number and banking transactions.

The worst thing is that the whole process is 100 percent transparent to the user. This worm has got a very speedy performance with regards to replication. It spreads in the networks rapidly and in no time obstructs the bandwidth completely. As a result the whole network traffic gets jammed and the spammers can reroute it for any disguise activities. Kido only infects Windows systems. The Windows operating system is so vulnerable that it allows this worm to infect the kernel, system’s main files and registry.

The Worm is very intelligent and follows different patterns while replicating. So it cannot be stopped completely by any single anti-virus system. The only way to stop it to get the new security patch and virus removal tool that is launched by Microsoft. Of course it only affects those running Windows, as people with the Apple MacBook running the Mac OS X operating system remain unaffected. The worm remains a major threat and is currently estimated to have infected up to 15 million computers worldwide.

Once again the alarms are sounding with regards to Apple Safari’s security. Recently it has been found that the Safari’s RSS feeds are not safe to use, both on the Mac and PC. This application is vulnerable to hacker attacks and it can allow any malicious web site to bring you some really serious repercussions when using Safari to capture RSS feeds.

Once trapped by the malicious site the hackers can read files on your hard disk drive. This can lead to the access to sensitive information such as e-mails, passwords, cookies or any other private data. Even the whole user account can be taken in control by the intruders and the whole process is completely transparent to the user. The interesting fact is that this security loophole has been identified by Apple itself but it hasn’t been fixed till now. So it’s highly recommended not to use Safari for RSS.

The problem is believed to be emerged due to some issues with the Apple’s Webkit. This is because the OmniWeb users are also in the danger zone. OmniWeb is the browser used in Mac machines, like the Apple MacBook, and uses the WebKit rendering engine. RSS Feeds were introduced in Safari in 2004 but this is the first time that it has also joined the family of vulnerable applications.

Apple Safari has created a buzz among various other web browsers like Firefox, Internet Explorer and Opera. After much hype a threat has been detected. Talking about its security, if you think that your computer is all safe and sound after using Safari then you could be mistaken. A “carpet bombing flaw” has been detected on the computers of Safari users.

There is a risk for window users and they should curtail the use of Apple Safari browser before patching the necessary security update. While using Safari with default settings it automatically opens unwanted or booby-trapped file with no prompting on the Windows users desktop. Due to this problem unwanted icons flood your desktop. Whenever a person opens Internet Explorer the unwanted file automatically causes all your notepad files to open. Sooner or later this force fed file takes full control of your computer where you are unable to do anything. This threat can make things all the more vulnerable for hackers. Of course they can choose far more nefarious code. Possessing the latest antivirus & security software is always recommendable. This carpet bombing flaw is occurring frequently among the Safari users.

Apple Safari can download files with no prompting. After discovering this flaw it has created havoc among the Safari users. At present this flaw exists in Apple Safari. So all you Safari users get alert as your computer or laptop can be hacked at any point of time by the online hackers or online eavesdroppers.

One of the most popular points that Mac fans bring up when pointing out how much better Macs are than Windows computers is how much more secure Macs are.  However, when Apple released the Safari browser for Windows testers quickly realized that the browser was anything but more secure than Internet Explorer 7.  This is especially troubling since Apple touted the Safari browser on its web page as being “secure from day one.”

Researchers downloaded and began playing with Safari on Windows almost the minute that it was released.  One researcher in particular, Thor Larholm, found a URL protocol handler injection vulnerability that allows commands to be executed remotely.  This was found less than two hours after installation.  Larholm was quick to note that Safari doesn’t handle URL validation in iframes like it should, which allows programs to manipulate protocol handlers in unpredictable manners. 

David Maynor of Errata Security also found bugs as well – six of them, he claims.  Of these six, four are DoS and two are remote code execution bugs.  Additionally, he claims multiple crashes just from idle use and especially from importing bookmarks into the browser, a feature that many, if not most, users will almost definitely use, at least upon initial installation.

While it seems to be lax on security, Safari is simply too stringent on some issues.  For instance, Safari simply will not allow open a website with expired or unsigned SSL certificates.  While this keeps users safe, it can be extremely frustrating when the user is familiar with the site and wishes to continue.  Firefox is much more clever in handling expired or unsigned SSL certificates in that it gives the user a choice of whether or not to continue by enabling a warning to pop up.  Safari users would just be forced to use another browser, probably Firefox. 

In its defense, Apple has been diligent in releasing updates for the Safari browser but not all claimed exploits have been thoroughly patched.  This may be due to the fact that many people that actively search out these exploits give feedback to the companies whose software they test.  This is particularly true of David Maynor.  Maynor has vehemently stated that Apple has chosen to attack his credibility instead of fixing crucial security exploits in his previous attempts to point them out to the company to be fixed.

Apple will hopefully address all of the concerns with their new browser as it is clear that they cannot rely on hackers to simply target Internet Explorer just because it is a more popular web browser these days – particularly if they want to enable their fans to continue the argument that Macs are more secure.

Microsoft Windows!

Although apple is happily touting the security of its new browser, the bad news are hitting hard.

Several first day vulnerabilities have already been discovered, amongst them memory errors and even code execution exploits.  Yes, that means someone could use a website to execute code on your computer.

This sheds a bad light on the application and we can just hope that Apple will adress those issues as soon as possible.

Right now, Firefox still seems to be the most secure browser out there.
