"Check who is visiting your profile" scam on Russian social network Vkontakte

Vkontakte is the Russian equivalent of Facebook and has been criticized for being a direct "clone". Well, scammers are "cloning" the most popular Facebook scams and porting them to this Russian platform as well.

One recurring scam, used to trick people into giving up credentials to their Facebook account, or executing a cross-site scripting attack against themselves, has it's equivalent at Vkontakte: hxxp://gosti-vk.p7h.in/?r=3262.

Here is a screenshot of the page translated into English:

Scam site
The site claims to be an official Vkontakte application (with a .in TLD!). The page uses the same logo, layout and colors as the official site. The fake user testimonials explain that they have found likely lovers checking out your profile.

You need to give your ID or profile link (no password required) to let the "app" figure out who is viewing your profile:

Form (translated in English) to enter user ID
I inserted a fake name (in English) and the app miraculously found 7 people who had looked at my profile!

Name of people who visited by non-existent profile
Before I had time to click on any links, I was also asked to enter my cell phone number to ensure that I was indeed a human:

Phone number must be entered

This is where the Russian scam differs from the Facebook scam. In the US, scammers try to get users to fill out surveys, install spyware or try "free" offers. In Russia, as shown in other scams, scammers make money by sending SMS messages with a surcharge.

Are Pinterest "Pin it" going the way of Facebook "Like"?

Pinterest is a new social network that has been getting a lot of press lately. Basically, Pinterest is a virtual board, where users can pin things they like online. They can share the content with their friends, follow other people, etc.

My Pinterest board
Like Facebook, Pinterest users can add items to their board from the website, but also by clicking on "Pin it" widgets set up by webmasters on any website, which are equivalent of the Facebook "like" widgets. Any new pin shows up as a notification for all people following you. Although Pinterest is very new (you need to first apply for an invitation to get your login after a couple of days) and has a small number of users, spammers are already abusing the "Pin it" widget.

This week, I found spam campaigns at pinterestpromo.info and giftinterest.com that use Pinterest as the main tool to propagate scams.

pinterestpromo.com
The scam is very similar to some previous Facebook spam campaigns: users have to click on the "Pin it" widget in order to receive a free iPhone or iPad. On these two sites, scammers have used a fake "Pin it" widget rather than the official widget code.


After clicking on the widget, the site redirects to another website, such as:
http://www.giftsforshoppers.com/aseg-1142?trkSessID=195212565&dLID=5084&pRdrTrkID=667421271&skipExit=[skipExit]&pLeadEmailAddress=[pLeadEmailAddress].

www.giftsforshoppers.com

The scam is the same as one that I described last week for a Groupon scam: the visitor has to fill out surveys or trial offers in the hope of getting a gift card or some other gadget.

Any website with features to spread links quickly to a trusted group of people is doomed to be abused by spammers.

Fake missing plugin warnings used for spam/spyware

A key element for a successful spam/malicious page is to establish trust with the visitor so that he will perform the requested actions. Users trust their browser, but not necessarily the content (i.e. web page) that it displays. A trick that I've blogged about earlier, is to fool the user into thinking that certain elements on the page are actually from the browser.

Recently, I've seen several websites showing a fake warning for a missing plugin. The fake warning is designed to look the same as the real warning shown by Firefox when the page requires a plugin that is not installed: a yellow bar at the top of the page with a link to install the plugin on the right, and a blue icon on the left.

Legitimate Firefox warning for a missing Adobe Shockwave plugin

On allostreaming.biz (French language), the fake warning is for a "missing" VLC plugin. You can tell that the warning is part of the page, and not part of the browser, because the scroll bar goes to the top of the warning, whereas the real warning is above the scroll bar (see the image above).

Fake warning for missing plugin
A look at the source code shows that the warning is indeed HTML from the page:

HTML code for the fake warning
The "VLC plugin" is the classic pay-per-install bundle, where the spammer gets paid for tricking the users into installing spyware/adware.

The spammers are using the same fake warning on all browsers, which is also a giveaway as browsers other than Firefox don't actually have the same warning for missing plugins. Anyway, the attack will likely fool users of other browsers into installing this adware/spyware.

Facebook used to make scams look legitimate

One of the recurring web spam themes I saw in 2011, was the "Work from home and make $X,000/month" scam. In some variations of the well-known and well-used scam, websites are set up to look like a well-established newspaper with a front-page (fake) article about making a lot of money from home.

Here are a few examples I saw earlier this year (now offline):


Fake NBC website at hxxp://news11bizopp.com/landing.php

Fake news site at http://www.nbcnews43.com/?news/articleid=8351

The new scam I found this week included an interesting new trick and is still online.

Fake news site at hxxp://newsday7.com/
The site is set up like the previous scams - it claims to be an online, established newspaper, which displays an article about someone who is making a lot of money, working from home.

At the top of the picture, which shows a woman and a girl, on the right, you can see a Facebook Like button that says "214,217 people recommend this. Be the first of your friends." Apparently, 214,217 went to his page and clicked on "Like", making this page look more legitimate.


At first, I thought this was a fake Facebook widget. But this is the real deal, as seen from the page HTML code:


Real Facebook widget (click on the image too see in full screen)
There is however a trick. The "Like" widget does not point to hxxp://newsday7.com/, but rather to http://www.facebook.com/CBS. As you can see in the images taken from the two websites, the number of Likes is the same:

214,217 Likes on hxxp://newsday7.com/
214,217 Likes on http://www.facebook.com/CBS

Facebook allows you to embed any Like widget on any website, even if the domains or URLs do not correspond. Scammers are using this trick to appear more legitimate, by tricking visitors into thinking their website has been visited and liked by many people.

My guess is that this technique is very effective, and will be used more and more by spammers and scammers.

2012 Security Predictions


It’s the most wonderful time of the year. A time when we set aside our quarrels and show compassion for complete strangers, realize that it’s better to give than to receive and in the security industry, let everyone know just how smart we are playing Nostradamus. Yes, it wouldn’t be December if I didn’t join in the chorus of prognosticators to let you know exactly what is in store for us all in the coming twelve months.

Mobile

With WebOS now officially an orphan, Blackberry OS racing to the grave and Windows Mobile still trying to get ready for the party, the victors can be crowned – iOS and Andorid have won. The interesting part of the race is about to begin, namely who has the best security model. Will it be Apple’s draconian, ‘we control everything’ or Google’s happy-go-lucky ‘come on in, everyone’s invited’ approach?
Prediction: The ‘do no evil’ company will struggle mightily to keep evil applications out of their App Marketplace. In an effort to avoid being to mobile what Windows is to PCs (a breeding ground for malware), Google will subtly make Android less open to both partners and developers. They will also announce an initiative to increase security screening for applications before deployment in the App Marketplace. Apple on the other hand will have comparatively few malicious apps to deal with, but at least three major OS flaws that impact all users (and make the jailbreak team happy). Apple will address the vulnerabilities several days late and apologize to no one. iPad 3 and iPhone 5 sales will turn financial analysts into giddy schoolgirls.

Enterprise

Thanks to marketing teams across the globe, APT (Advanced Persistent Threat) has become a meaningless buzzword in the security lexicon. Let’s therefore ditch that term and instead focus on targeted attacks, specifically those focused on enterprises with the goal of corporate espionage or to inflict financial damage. Many praised Google for coming forward in January 2010 to reveal that they and others had been the victim of a sophisticated targeted attack, likely originating from China. Many in the public mistakenly assumed that this was a new and previously unseen event on the security stage. What was new about it was the openness displayed by Google in discussing the situation, not the class of attack.
Prediction: The term ‘APT’ will go the way of ‘eCommerce’ and the Dodo bird, but stories of targeted attacks against enterprises will rise tenfold in the media. This will be a reflection of increased activity by attackers as they broaden their reach to smaller companies and decisions by corporate council to disclose details of an attack rather than to suppress the information and risk litigation for trying to cover up such activity.

Web

Want to know a secret for making security predictions? Take a look at what was being discussed at security conferences 2-3 years ago. At Black Hat DC 2009, I discussed the dangers of persistent web browser storage. One of the key technologies that will be taking browser storage to the next level is HTML5. In 2009, HTML5 apps were few and far between. Thanks in large part to mobile browsers; HTML5 is now much more mainstream. As with any new technology, developers are quickly rushing to play with the new kid on the block and publishing their goods, without taking the time to understand the security implications.
Prediction: We’ll see an increasing number of web application vulnerabilities in HTML5 apps, not because the technologies behind them are insecure, but because HTML5 is not well understood from a security perspective.

Hardware

Security in the hardware space is at least ten years behind security in the software industry. This isn’t so much a reflection of the good work being done in software, as it is the reality of software vendors being forced to address an issue that was impacting business. Thanks to the efforts of many great researchers investing countless hours doing QA work that should have been done long before products hit the shelf, today most major security vendors have no choice but to employ security response teams and take vulnerability disclosure very seriously.
Hardware vendors simply haven’t faced the same scrutiny, but that’s changing. This year at Blackhat, I spoke about the sad state of embedded web servers and recently researchers at Columbia University discussed the ability to remotely cause physical damage to HP printers due to security flaws.
Prediction: Hardware vendors will get a wake-up call as researchers shift their efforts and party like it’s 1999.

Social

The majority of malicious activity surrounding social networks today primarily involves unwanted or nuisance traffic as opposed to attacks that lead to a fully compromised machine. We’re seeing an increase in likejacking and self-inflicted JavaScript injection attacks that have the same overall goal – drive web traffic or prompt software downloads that can earn the scammer a few cents per click.
Social networks such as Facebook are of value to more serious criminals, but mainly for reconnaissance during targeted attacks. They are a great resource for learning background information about an individual and uncovering relationships, all of which can be of great value for social engineering. We’re not however, commonly seeing the communication aspects of social networks used to deliver malicious payloads directly to victims or investments in uncovering web application vulnerabilities used to compromise end user machines as opposed to spreading the aforementioned scams.
Prediction: Attackers will raise the bar and leverage social networks for more sophisticated attacks, the goal of which will be full compromise as opposed to marketing financial scams.
Merry New Year!
