Hello, welcome to this month's blog on the Microsoft patch release. This month the vendor is releasing four bulletins covering a total of six vulnerabilities. All six of this month's issues are rated ’Important’.

As always, customers are advised to follow these security best practices:

  • Install vendor patches as soon as they are available.
  • Run all software with the least privileges required while still maintaining functionality.
  • Avoid handling files from unknown or questionable sources.
  • Never visit sites of unknown or questionable integrity.
  • Block external access at the network perimeter to all key systems unless specific access is required.

Symantec Security Response | 14 Jan 2014 08:02:58 GMT

We recently encountered a website of a major Japanese book publisher and distributor, of books, magazines, comics, movies, and games, injected with a malicious iframe leading to another website hosting an exploit kit.

As far as we know, at least three files on the book publisher’s site were compromised.

The malicious iframe was present across multiple pages including the homepage. Our telemetry shows the first potential victim visited the site at approximately 22:00 PST on January 5, 2014 (15:00 JST on January 6, 2014). The security issue was not fixed until late on January 8, PST (in the evening of January 9, 2014 JST).

The malicious iframe loads another website, hosting an exploit kit, as soon as a user visits the book publisher’s site. The exploit kit...

Energy is crucial to our modern lifestyle. Disturbingly, reports of attempted attacks against the companies and industries that supply it are increasing every year. In the first half of 2013, the energy sector was the fifth most targeted sector worldwide, experiencing 7.6 percent of all cyberattacks. So, it’s not surprising that in May 2013, the US Department of Homeland Security warned of a rising tide of attacks aimed at sabotaging processes at energy companies. At Symantec, our researchers are finding that traditional energy utility companies are particularly concerned about scenarios created by the likes of Stuxnet or Disttrack/Shamoon which can sabotage industrial facilities. 
 
We are also learning that aggressors who target the energy...

Japanese animation is known as anime and Japanese comics are known as Manga. In the last two decades, these industries have grown in popularity across the world. People know that cashing in on the latest trend is often an easy way to earn money, and many legal and illegal businesses often take advantage of this. The popularity of anime and manga has opened up a new avenue for cybercriminals to push malware threats onto unsuspecting fans through malvertisements and mobile risks.

During the early 90’s Japanese comics experienced a boom in the US market and earned their place on the shelves of major book sellers. Before these books can be read by fans who do not speak Japanese, they must be translated. The number of manga being officially translated is growing, but this doesn’t seem to be enough to keep fans satisfied. In addition, only the more popular titles are candidates for translation.

One problem the...

The New Year has started and many people are still holding to their resolutions. Besides the usual suspects of exercising more and quitting smoking, some might have planned on finding a new apartment. Unfortunately, this also means a rise in prepaid rental ad scams. So be cautious while you’re searching for a new home.

The prepaid rental scam advertisements can be encountered on nearly any platform and in most countries. The ads often look very professional; some are even copies of real ads from legitimate sources. We have seen them on established apartment rental sites, online notice boards, B&B agency sites, and even in the classified ads section of newspapers. The website owners try their best to spot false advertisements and delete them as fast as possible, but there is always a chance that there is a new ad that hasn’t been removed yet.

The scam is pretty simple. Once the victim shows interest in the apartment the alleged landlord informs the victim that he...

In the first week of 2014, we came across a website using tried and tested social engineering techniques to coerce victims into installing malware. The domain http://newyear[REMOVED]fix.com, was registered on December 30, 2013. Based on our research, 94 percent of  attacks appear to be targeting users based in the United Kingdom through  advertising networks and free movie streaming and media sites.

The attackers attempt to trick victims using the following techniques:

  • A URL containing the words “new year” and “fix”
  • A professional looking template (from Google, Microsoft or Mozilla) telling the victim that a critical update is necessary for their system to function properly
  • Redirecting the user, based on their browser type, to a fake but convincing Chrome, Firefox, or Internet Explorer Web page.
  • Using a JavaScript loop to force the victim to give up and stay on site – users have to click on the “Yes/No” option 100 times in...

Recently we have observed a series of mobile ads intended to scare users into believing that their device is infected with a threat called “Trojan: MobileOS/Tapsnake”.

Figure 1. Fake Tapsnake infection warnings
 

The malware alert is fake. Tapsnake is an older Android threat (we blogged about it in 2010 and detect it as Android.Tapsnake) that just happens to be mentioned in these ads to make them appear more authentic. We visited a site serving these ads using a brand new Android device with a fresh install and nothing on it and still received this alert. Users of Apple's iPhone...

Webcam blackmailing 1.jpg

Recently, we wrote about creepware and how people use it to spy on unsuspecting victims through webcams. As the name implies, this is really creepy. Unfortunately, there are other similar threats on the Internet. Another scam that has become very popular this year is webcam blackmailing. In these cases, the scammers don’t hide the fact that they are using the webcam.

The scam starts with a simple contact request on a social network or dating site. In general, the profile sending the request appears to be the scammer (posing as a woman), and the request is sent to single men. After a bit of...

“Because that’s where the money is!” This is a quote frequently attributed to Willie Sutton as the answer he allegedly gave when asked why he robbed banks. Even though Mr. Sutton never gave this answer, it still holds true. 
 
This paradigm also holds true when it comes to today’s financial malware. Online banking applications are where money is moved; hence they are also the focus of attackers. It should not come as a surprise that we still see further development of Trojans targeting online banking services. One example that we recently blogged about is the Neverquest Trojan, a successor of Trojan.Snifula, which was first seen in 2006 but is still in use. 
 
The number of infections of the most common...

The Browlock ransomware (Trojan.Ransomlock.AG) is probably the simplest version of ransomware that is currently active. It does not download child abuse material, such as Ransomlock.AE, or encrypt files on your computer, like Trojan.Cryptolocker. It does not even run as a program on the compromised computer. This ransomware is instead a plain old Web page, with JavaScript tricks that prevent users from closing a browser tab. It determines the user’s local country and makes the usual threats, claiming that the user has broken the law by accessing pornography websites and demands that they pay a fine to the local police.
