Hacker Broke into a Mac

Mac SecurityA hacker managed to break into a Mac and win a $10,000 prize as part of a contest started at the CanSecWest security conference in Vancouver.

In winning the contest, he exposed a hole in Safari, Apple’s browser. "Currently, every copy of OS X out there now is vulnerable to this," said Sean Comeau, one of the organizers of CanSecWest.

The conference organizers decided to offer the contest in part to draw attention to possible security shortcomings in Macs. "You see a lot of people running OS X saying it’s so secure, and frankly, Microsoft is putting more work into security than Apple has," said Dragos Ruiu, the principal organizer of security conferences including CanSecWest.

Dino Di Zovie, who lives in New York, sent along a URL that exposed the hole. Because the contest was only open to attendees in Vancouver, he sent it to a friend who was at the conference and forwarded it on.

The URL opened a blank page but exposed a vulnerability in input handling in Safari, Comeau said. An attacker could use the vulnerability in a number of ways, but Di Zovie used it to open a back door that gave him access to anything on the computer, Comeau said.

The vulnerability won’t be published. 3Com’s TippingPoint division, which put up the cash prize, will handle disclosing it to Apple.

One reason Macs haven’t been much of a target for hackers is that there are fewer to attack, said Terri Forslof, manager of security response for TippingPoint. "It’s an incentive issue. The Mac is not as widely deployed of a platform as, say, Windows," she said. In this case, the cash may have provided motivation.

Was it a coincidence that on late Thursday Apple released a patch for 25 vulnerabilities in OS X?  :)

Firefox Rise – IExplorer Dies

According to xitimonitor Firefox is getting 25% share in Europe. That is a huge deal – now every 4th European uses Firefox to browse the www. Here is a chart that shows European Firefox usage per country:

 Firefox Europe Usage

 
    Besides Europe, Firefox wheels spin all over the World, for example in US over 15% of users use Firefox, for Australia it is 25%, almost 12% in South America, over 13% in Africa and around 12% in Asia. Here is a snapshot:
 
Firefox World Usage
 

    There are three more factors that play in favor to Firefox:

  • Everybody wants MAC :)
  • Ubuntu is getting very popular
  • Vista is not exactly going anywhere, while XP is going, but mostly going down

    For somebody who does not do any web development and uses Microsoft Windows products (XP, Vista – well who uses Vista anyway.. ), this may not sound like great news, but for everybody else it is a pleasant "turn around", and it is going towards:

  • Much better browsing experience for people with MAC, Linux, and other non-M$ OSs
  • No more optimizing for IE, including those ugly JavaScript if(IE)/switch(OS) statements, and different CSS

    Yes, the idea is that Internet Explorer will die out the same way it was born – along with Windows
    It will not happen overnight or tomorrow, but it is already happening today…

Sexy TOP vs Human HTOP

To check performance of the Unix/Linux box top command is used frequently. This is what top‘s output usually looks like:

 top command on Ubuntu Linux

     While top command is very useful, it has very clumsy "human interface". There is a much better alternative to tophtop which is a free (GPL) ncurses-based process viewer. It is similar to top, but allows to scroll the list vertically and horizontally to see all processes and their full command lines. Tasks related to processes (killing, renicing) can be done without entering their PIDs, and of course htop has a much better human interface that looks similar to:

htop command on Ubuntu Linux

Comparison between htop and top

  • In ‘htop’ you can scroll the list vertically and horizontally to see all processes and complete command lines.
  • In ‘top’ you are subject to a delay for each unassigned key you press (especially annoying when multi-key escape sequences are triggered by accident).
  • ‘htop’ starts faster (‘top’ seems to collect data for a while before displaying anything).
  • In ‘htop’ you don’t need to type the process number to kill a process, in ‘top’ you do.
  • In ‘htop’ you don’t need to type the process number or the priority value to renice a process, in ‘top’ you do.
  • ‘htop’ supports mouse operation, ‘top’ doesn’t
  • ‘top’ is older, hence, more used and tested

    htop is an Open Source project, hence can be easily downloaded and installed on U/Linux system. For example it can be downloaded and installed on Ubuntu with just one command:

sudo apt-get install htop

Be aware!    It appears that although ‘htop’ provides some cool enhancements, ‘top’ remains to be one of the sexiest Unix commands ever according to GOOGLE. Just search for "man top" and along with "Unix Manual Pages for top" get "Man on Top Sex Positions" from GOOGLE. :)
