Blessed are the nerds (for they break the software)

Beta programs usually have two mutually exclusive goals:

  1. To build up buzz for a new product—as in the case of Gmail and now Google +.
  2. To test and improve a piece of software nearing release.

Right now we are in the middle of the beta for Internet Security 2012. And if you are now thinking, “Yes, I want to test this piece of new software till smoke is coming out of my PC” then we hope you’ll sign up for our beta program. However, as Internet Security 2012 is still being developed we don’t think the beta is for everyone.

We offer free licenses for our Anti-Theft for Mobile and have in the last year given out licenses to our Mobile Security and even our 2010 AV-Test Product of the Year Award-winning Internet Security via our Facebook Page. And when Internet Security 2012 is available to the public, we hope the whole world will take our free trial.

But for the beta, we’re only looking for passionate software experts who will help break our software. Yes, break it. Or at least tell us how to make it perform better for you. That’s how we work to bulletproof the protection we provide. It’s hard work and the finished result is a tribute to the beta testers’ tenacity and ingenuity.

Are you a software aficionado yourself ? Do you know any experts that would like to put our protection to the test?

The sign up process is in-depth and it will help you or your friends and us know if the program is a good fit.

Thanks for following us. Your interest in F-Secure is greatly appreciated.

How far are you ready to go to see a juicy video? [POLL]

Many of you have seen them. And some of you have no doubt been victims too. Malware spreading through social media sites, like Facebook, is definitively something you should look out for. You know those posts. You raise your eyebrows when old Aunt Sophie suddenly shares a pornographic video with all her friends. You had no idea she was into that kind of stuff! Well, she isn’t (necessary). She’s just got infected with a special kind of malware called a social bot. So what’s going on here? You might feel tempted to check what “Aunt Sophie” really shared with you. But unfortunately your computer isn’t set up properly to watch the video. It lacks some kind of video thingy that need to be installed. Luckily it is easy to fix, you just click the provided link and approve the installation. And you are ready to dive into Aunt Sophie’s stuff. Yes, you probably already figured out where this is going. The social bots are excellent examples of how technology and social tricks can work together. The actual malware is naturally the “video thingy” that people are tricked to install. To be more precise, it’s usually an extension to your browser. And it’s often masqueraded as a video codec, that is a module that understands and can show a certain video format. Once installed, these extensions run in your browser with access to your social media accounts. And your friends start to receive juicy videos from you. There are several significant social engineering tricks involved here. First you are presented with content that people want to see. Juicy things like porn or exposed celebrities always work well. But it may actually be anything, from breaking news to cute animals. The content also feels safer and more trustworthy because it seems to come from one of your friends. The final trick is to masquerade the malware as a necessary system component. Well, when you want to see the video, then nothing stops you from viewing it. Right? It’s so easy to tell people to never accept this kind of additional software. But in reality it’s harder than that. Our technological environment is very heterogeneous and there’s content that devices can’t display out of the box. So we need to install some extensions. Not to talk about the numerous video formats out there. Hand on heart, how many of you can list the video formats your computer currently supports? And which significant formats aren’t supported? A more practical piece of advice is to only approve extensions when viewing content from a reliable source. And we have learned that Facebook isn’t one. On the other hand, you might open a video on a newspaper or magazine that you frequently visit, and this triggers a request to install a module. This is usually safe because you initiated the video viewing from a service that shouldn’t have malicious intents. But what if you already are “Aunt Sophie” and people are calling about your strange posts? Good first aid is going to our On-line Scanner. That’s a quick way to check your system for malware. A more sustainable solution is our F-Secure SAFE. Ok, finally the poll. How do you react when suddenly told that you need to download and install software to view a video? Be honest, how did you deal with this before reading this blog?   [polldaddy poll=9394383]   Safe surfing, Micke   Image: screenshot

Why are Android bugs so serious?

Yet another big vulnerability in the headlines. The Metaphor hack was discovered by Israel-based NorthBit and can be used to take control over almost any Android device. The vulnerability can be exploited from video files that people encounter when surfing the web. It affects all versions of Android except version 6, which is the latest major version also known as Marshmallow. But why is this such a big deal? Severe vulnerabilities are found all the time and we receive updates and patches to fix them. A fast update process is as a matter of fact a cyber security cornerstone. What makes this issue severe is that it affects Android, which to a large extent lack this cornerstone. Android devices are usually not upgraded to new major versions. Google is patching vulnerabilities, but these patches’ path to the devices is long and winding. Different vendors’ practices for patching varies a lot, and many devices will never receive any. This is really a big issue as Android’s smartphone market share is about 85% and growing! How is this possible? This underlines one of the fundamental differences between the Android and iOS ecosystems. Apple’s products are planned more like the computers we are used to. They are investments and will be maintained after purchase. iOS devices receive updates, and even major system upgrades, automatically and free of charge. And most users do install them. Great for the security. Android is a different cup of tea. These devices are mostly aimed at a cheaper market segment. They are built as consumables that will be replaced quite frequently. This is no doubt a reasonable and cost-saving strategy for the vendors. They can focus on making software work on the currently shipping devices and forget about legacy models. It helps keeping the price-point down. This leads to a situation where only 2,3% of the Android users are running Marshmallow, even half a year after release. The contrast against iOS is huge. iOS 9 has been on the market about the same time and already covers 79% of the user base. Apple reported a 50% coverage just five days after release! The Android strategy backfires when bugs like Metaphor are discovered. A swift and compete patch roll-out is the only viable response, but this is not available to all. This leaves many users with two bad options, to replace the phone or to take a risk and keep using the old one. Not good. One could think that this model is disappearing as we all grow more and more aware of the cyber threats. Nope, development actually goes in the opposite direction. Small connected devices, IoT-devices, are slowly creeping into our homes and lives. And the maintenance model for these is pretty much the same as for Android. They are cheap. They are not expected to last long, and the technology is developing so fast that you would be likely to replace them anyway even if they were built to last. And on top of that, their vendors are usually more experienced in developing hardware than software. All that together makes the IoT-revolution pretty scary. Even if IoT-hacking isn’t one of the ordinary citizen’s main concerns yet. So let’s once again repeat the tree fundamental commands for being secure on-line. Use common sense, keep your device patched and use a suitable security product. If you have a system that provides regular patches and updates, keep in mind that it is a valuable service that helps keeping you safe. But it is also worth pointing out that nothing as black and white. There are unfortunately also problematic update scenarios.   Safe surfing, Micke     Photo by etnyk under CC

going back in time with macro malware

Hack to the Future: The Return of Macro Malware

We who write stuff in the security industry are used to dashing off sentences like, “Online attacks are becoming more and more advanced” or “Malware is continually evolving in sophistication.” But in the past year we experienced a surprising throwback to one type of malware from an earlier era. Malware that uses a rather old technique, but it’s causing plenty of trouble nonetheless. It kinda feels like we've gone back in time. I’m talking about macro malware. It’s something we hadn’t seen prominently since the early 2000’s. And now, as touched on in our just released Threat Report covering the 2015 threat landscape, it has reared its head again. What is macro malware? Macro malware takes advantage of the macro feature in Office documents to execute commands. And macros are simply shortcuts the user can create for repeated tasks. For example, let’s say you are creating a document in Word and you find yourself repeatedly editing text to be red with a yellow highlight, 16 point, italic and right aligned. To save time, you can create a macro of your commands and then whenever you need that kind of style, simply run the macro. A little history Macro malware was common back in the 1990’s and early 2000’s. The first macro malware, Concept, was discovered in 1995, although it was basically harmless, simply displaying a dialogue box. In 1999, one of the most notorious macro malware, Melissa, was discovered. Melissa emailed itself to 50 addresses in the user’s address book, spreading to 20% of the world’s computers. But macro malware wouldn’t last long. When Microsoft released Word 2003, the default security settings were changed to stop macros from automatically running when a document opened. This made it more difficult to infect a computer through macros and attackers mostly dropped them to focus on other methods. So what happened? Why is it back again? The re-emergence, according to Sean Sullivan, Security Advisor in F-Secure Labs, may be correlated with the decline of exploitable vulnerabilities due to security improvements in today’s common software applications like Microsoft Office. Exploits have been one of the most common ways to infect machines in recent years, but with fewer software holes to exploit, malware authors seem to be reverting to other tricks. How it’s successful Today’s macro malware attempts to get around Microsoft’s default settings with a simple trick. When a document is opened, the information inside doesn’t appear properly to the viewer – for example, sometimes the document looks like scrambled gobbledygook. Text in the document claims that macros, or content, must be enabled for proper viewing. Here’s one example: Curiosity? Just plain unaware? Whatever the reason, as Sean says, the malware’s reappearance has been successful because “People click.” Once macros have been enabled, the malicious macro code is executed – which then downloads the payload. Macro malware is used by crypto-ransomware families like Cryptowall and the newest threat Locky. These families encrypt the data on a computer and then demand payment to unencrypt it. Although we don’t know for sure, it’s possible it was macro malware that was used in the holding of a Hollywood hospital for ransom last month. The banking Trojan Dridex, which allows attackers to steal banking credentials and other personal info from infected machines, also uses the technique. How to avoid it Fortunately, if you use security from F-Secure, you’re protected from these threats. But aside from that, the old advice still holds: Be wary of email attachments from senders you don’t know. And take care not to enable macros on documents you’ve received from sources you’re not 100% sure of.   "Back to the Future" banner image courtesy of Garry Knight,
