I know it's customary to simply rattle off a "top 10 list" of bullet points related to possible security predictions further along in the year, but I thought I'd rather go into a little more detail with this one. As such, my bullet points are few, but my concerns are many.

What does the year hold? Lots and lots of problems for Myspace, from the looks of it. Don't forget the other Social Networking sites (such as Facebook and Orkut) too. Of course, claiming there will be issues for these sites is perhaps to state the completely and utterly obvious, but we're barely a week into the new year and already we have:

* Fake "friend adds" from someone posing as "Myspace Tom" trying to sell you ringtones;

* Zango in the news regarding an application on Facebook apparently designed to push popup adverts;

* Sites that provide services for Myspace in the line of fire too.

However you look at it, Social Networking is currently where all the action is, and - in the same way that some of the biggest security stories of 2007 were web 2.0 escapades, expect a lot more of the same this year. Although Facebook and Orkut have experienced a surge in recent months with regard malicious (and supposedly "non malicious") attacks, Myspace will clearly remain the breeding ground for new techniques and attacks launched upon end-users.

Myspace shows no indication of locking down the functionality on end-users pages that makes it easy for bad guys to cause trouble, and while the ability to post videos, music and custom backgrounds to your page is appreciated, the problems and security issues these same "bonus features" create is not so welcome.

If there is a major security breach involving Myspace, will they even be able to react in time given the responses I was met with when trying to warn them of an issue recently?

Sadly, it seems like a distant prospect at this point.

Instant Messaging attacks fell under the radar a little bit with regards major breaking stories in 2007, but it's worth remembering that these hijacks are still out there in full force, even if we are all currently dazzled by the slow motion trainwreck that is the world of social networking.

Expect Skype Worms to become more and more commonplace - in fact, these attacks may drop under the radar more than any other, due to the constantly reused infection files by the bad guys. The first part of 2007 brought a flurry of news reports as we discovered a network jumping Skype Worm - however, the current attack of choice continues to be reworked Warezov variants, and this can only mean one thing - lack of coverage and a general sense of "looking for something more interesting" as we all grow tired of Warezov variant number 600,308 rumbling across the Skype network.

Of course, these attacks will still continue to be successful, whether we continue to read about them or not.

With that in mind, it's time to make a few small predictions for the older IM networks - well, one, actually. Expect more custom built infections for geographical areas you wouldn't have previously expected to be exploited. The Singworm (targeting MSN users in the Singapore region) springs to mind. As researchers grow tired of seeing the same old hijacks time after time and start to explore what's lurking in other regions, we'll start to read about new and interesting attacks from further afield. In some ways, that's already happened with regards the area of Adware - as the "old guard" of companies such as Zango, Direct Revenue and DollarRevenue either go out of business or reform, researchers have started to look at the "next generation" of Adware coming out of China.

Sadly, there will be more than enough for us to get to grips with. Indeed, we might start pining for the more straightforward threat landscape we knew and understood as we spend the year being battered by sales pitches in Chinese, EULAs in Korean and hacking forums written in Malay.

Singapore: Time To Talk

See that building in the middle? No, not that one, the other one. Yeah, there you go. That's Copthorne Kings, where we'd be doing our talky-conference thing for a whole bunch of people. Unfortunately on the morning of the presentation I was dropped off on the other side of a particularly nasty dual carriageway at the wrong hotel. Much Run Lola Run style hilarity ensued as I has to seek out an overpass and leg it to the right hotel with minutes to go.

Eventually I ran into the right lobby to be greeted by this:

....which was a bit more promising than the entirely blank stares handed to me by the dudes in the wrong hotel. (You'll notice that, rushed as I was, I still had time to take a picture. That's because there is always time to take a picture). A quick dive into the elevator and....

...I'm making my excuses and entering, which is odd because it's usually the other way round. Oh well. Before I knew it, the organiser had dispensed with his incredibly brief introduction and it was on with the show.

There were a number of talks on the day, the majority of which focused on presenting the audience with various kinds of solutions with regards the Enterprise environment. Honestly, it wasn't as dry as it sounds and this guy in particular:

...was incredibly funny and entertaining. I thought people might take this side of things a little too seriously based on previous experiences of more "corporate" events but it was quite loose and relaxed. Always a good thing, if you ask me. And I know you are.

The majority of my talk focused on the methods used to hunt down YoGangsta50 and "chase him offline". We also looked at a variety of hacks, cracks and exploits from around the World. In some of the other talks, the focus seemed to be on Phishing which is really taking off here in a big way - sadly I couldn't get hold of any other presentation slides, but there were some really clever examples.

Of course, the talks here focused on Enterprise and business use. My feeling is that, for the regular users, its business as usual with regards having to avoid the nasty stuff. Here's a perfect example, right?

Anyway, the conference finally came to a close and the general opinion was that it was a worthwhile event. I had a great time and would like to thank everyone involved in making the whole thing happen, and making sure I didn't get lost and fall in a river or something.

Till next time, Singapore...

Recently, I was in Singapore to give a number of talks on Spyware and Adware attacks. Interestingly, a number of people in the area Emailed me to let me know about something infecting their friends via MSN Messenger. As we investigated further, it did indeed seem to be based around the Singapore area (with a few mentions of it on Chinese forums, too). Here's a screenshot from a popular Singapore community forum:

...note the Flag of Hong Kong in the bottom left hand corner. All the cases we've seen of this so far have been limited to the Singapore region, with a couple of individuals mentioning it on Hong Kong-centric forums. Of course, this doesn't mean there aren't other victims out there but the spread so far seems to be quite limited.

There are many, many domains hosting the main Executable (dubbed "Singworm") pushed by the Instant Messaging infection link, the majority of which are hosted in Hong Kong and Taiwan. Yet another file (Winsys.exe) is downloaded from a number of different servers, one of which is apparently running out of Israel.

Variants of Winsys.exe have been known to be involved in various types of data theft, including login details, banking information and personal data.

The worm itself is mostly built for Spamming, with elements of the Stration Worm and other pieces of Malware thrown in for good measure.

It starts, as it always does, with the downloading and execution of a single file - in this case, rather oddly called "I.am.exe":

As soon as you run the file, the system attempts to start sending spam via the collection of files already deposited on the PC. At certain points in time, the amount of Spam the system was trying to send was so much that the testbox slowed down to a crawl and a reboot was needed. Here's a few of the files dropped into the System32 Folder:

At this point, if you have MSN Messenger the inevitable infection link will appear in the chat window of your contacts, which says "here are new smiles for MSN, they are incredible!":

....and of course, you'll send your infection link again.....and again.....and again.....

At this point, detection for most of the files involved in this on Virustotal.com is sketchy at best. We've notified MSN of this threat - in the meantime, if you're in the Singapore and Hong Kong regions, be aware of any strange links coming through from your colleagues...
