AP – Trading jokes and swapping leads, investigators from the FBI and Scotland Yard spent the conference call strategizing about how to bring down the hacking collective known as Anonymous, responsible for a string of embarrassing attacks across the Internet.

In case you weren’t able to make it (or missed the live stream) Rasmus Lerdorf gave a presentation last night at Etsy as a part of their “Code as Craft” series. They recorded the session and you can watch it here.

He talks about a few things:

• the history of the PHP language
• the state of PHP currently
• what’s coming up in 2012
• and touches some on the upcoming PHP 5.4 features.

You can find more about their “Code as Craft” series (and other videos) on the Etsy page.

AP – The goody-two-shoes among us say it’s better to give than to receive. That’s not true for the average Facebook user, though.

Last week I presented my research about “Adding ASLR to jailbroken iPhones” at the Power of Community 2010 (POC2010) security conference in Seoul. During my talk I explained how one can use a modified ‘rebase’ utility to rebase the dynamic linker dyld on the iPhone. Rebasing dyld is important because it contains enough code gadgets that can be used to kickstart arbitrary shellcode on jailbroken iPhones. A tool called Antid0te will be released until the end of this year that allows normal users to add ASLR to their iPhones. The release of this tool was originally planned for 24th December 2010 but it had to be postponed because I got really ill and also my glasses broke.

Anyway a few days ago I demonstrated how my “rebase dyld” research that was originally done for the iPhone applies directly to the dynamic linker used by Mac OS X Snow Leopard. I released a short article describing how one can rebase his dyld binary with a patched ‘rebase’ utility which I also released. This can be used to rebase your own dyld binary to a different position. Rebasing dyld to an address other than the normal one, improves the security of your Mac because all the public articles/techniques about state of the art Mac OS X exploitation assume/require the dyld binary to be loaded at a fixed address. All attacks based on this will fail once you have rebased your dynamic linker binary.

So enjoy this little christmas present until I am fit enough to release antid0te.

Jeremy Cook is back with the next part of his series looking at the handy features PHP’s SPL provides. In this new post he looks at the ArrayAccess interface and how it can make your data more accessible to PHP’s own array handing functions.

ArrayAccess allows you to treat an object that implements it as if it is an array for the purposes of setting, unsetting and retrieving data from it. Please note the emphasis in the last sentence! ArrayAccess does not make an object behave like an array in any other way. If you pass an object that implements ArrayAccess to a PHP array function such as in_array() you’ll still get an error. This will become a little clearer with some of the examples below.

He shows what you’ll need to use this interface in your class – implementing the interface and defining a set of four methods to get/set and check for the value in your array. He includes a practical example of pulling data back from an API and wrapping it in a class to make accessing it simpler (also implementing the Countable interface as well, see the previous post for more on that). Code is include to illustrate how it can be used.

AP – Facebook is friending Wall Street: The Internet social network is going public in a stock offering that could value it at up to $100 billion, eight years after its computer-hacking CEO Mark Zuckerberg started the service at Harvard.

The Server-Side Magazine site has posted an interview (10 questions) with Andrei Alexandrescu, a research engineer currently working at Facebook.

Today we caught up with Andrei Alexandrescu for a “10 Question” interview. He is a Romanian born research engineer at Facebook living in the US, you can contact him on his website erdani.com or @incomputable. We will talk about some of the juicy stuff that going on at Facebook, so let’s get started.

Their questions include:

• What’s your development setup?
• What do you think of PHP as a language from your perspective, regarding that Facebook was initially written in PHP then transformed to C++ using HipHop for PHP. What are the pros and cons of using C++ over PHP at Facebook?
• Currently, what kind of research do you conduct at Facebook? (or is this confidential?)
• Tell us a little bit about the D programming language, in contrast to C, PHP, Ruby and others. In what fields can someone apply D?
• Also, what kind of advice can you give for developers who are considering to apply to Facebook? What kind of skills is Facebook looking for in a potential candidate. Is it really important to be a graduate CS? What kind of skills do the majority of Facebook employees possess?

Read the full interview for his answers to these and other interesting questions.
