F-Secure Mobile Security Detects 100% of Mobile Malware

mobileIn March, AV-Test tested 26 mobile malware solutions and we’re proud to announce F-Secure Mobile Secure received a protection score of 6.0 out of 6.0.

Our solution blocked 100% of the representative set of malicious apps discovered in the last 4 weeks tested. Nice.

The test went beyond just testing the ability to block bad software.

PC Magazine‘s Neil J. Reubenking explains:

Antivirus protection is important, but for mobile users additional security features like anti-theft can be just as important. In the initial test of Android-based antivirus, AV-Test noted whether each product included specific additional security features: 1) anti-theft (remote lock, wipe, and locate), 2) call blocking, 3) message filtering, 4) safe browsing, 5) parental control, 6) backup, and 7) encryption. In the latest test, products are scored on whether they include extra security features, either the seven from the preceding list or other useful security features.

You can see our complete score card here.

We want to congratulate all the fellows on who work to make our Mobile Security the best protection in the world.

And you can try Mobile Security for free here.

Cheers,
Sandra

Juhannus

How To Prepare Yourself and Your Phone For Juhannus

In Finland, there is this thing called juhannus. A few years ago, our former colleague Hetta described it like this: Well, Midsummer – or juhannus – as it is called in Finnish, is one of the most important public holidays in our calendar. It is celebrated, as you probably guessed, close to the dates of the Summer Solstice, when day is at its longest in the northern hemisphere. Finland being so far up north, the sun doesn’t set on juhannus at all. Considering that in the winter we get the never ending night, it’s no surprise we celebrate the sun not setting. So what do Finns do to celebrate juhannus? I already told you we flock to our summer cottages, but what then? We decorate the cottage with birch branches to celebrate the summer, we stock up on new potatoes which are just now in season and strawberries as well. We fire up the barbecue and eat grilled sausages to our hearts content. We burn bonfires that rival with the unsetting sun. And we get drunk. If that isn't vivid enough, this video may help: [protected-iframe id="f18649f0b62adf8eb1ec638fa5066050-10874323-9129869" info="https://www.facebook.com/plugins/video.php?href=https%3A%2F%2Fwww.facebook.com%2Fsuomifinland100%2Fvideos%2F1278272918868972%2F&show_text=0&width=560" width="560" height="315" frameborder="0" style="border: none; overflow: hidden;" scrolling="no"] And because the celebration is just so... celebratory, it's easy to lose your phone. So here are a few ways to prepare yourself for a party that lasts all night. 1. Don't use 5683 as your passcode. That spells love and it's also one of the first passcodes anyone trying to crack into your phone will try. So use something much more creative -- and use a 6-digit code if you can on your iPhone. You can also encrypt your Android. 2. Write down your IMEI number. If you lose your phone, you're going to need this so make sure you have it written down somewhere safe. 3. Back your content up. This makes your life a lot easier if your party goes too well and it's pretty simple on any iOS device. Just make sure you're using a strong, unique password for your iCloud account. Unfortunately on an Android phone, you'll have to use a third-party app. 4. Maybe just leave it home. Enjoy being with your friends and assume that they'll get the pictures you need to refresh your memory. And while you're out you can give your phone a quick internal "clean" with our free Boost app. [Image by Janne Hellsten | Flickr]

Could the Sony and Hacking Team hacks have been detected sooner?

Hacks in the Headlines: Two Huge Breaches That Could Have Been Detected

The Sony hack of late 2014 sent shock waves through Hollywood that rippled out into the rest of the world for months. The ironic hack of the dubious surveillance software company Hacking Team last summer showed no one is immune to a data breach - not even a company that specializes in breaking into systems. After a big hack, some of the first questions asked are how the attacker got in, and whether it could have been prevented. But today we're asking a different question: whether, once the attacker was already in the network, the breach could have been detected. And stopped. Here's why: Advanced attacks like the ones that hit Sony and Hacking Team are carried out by highly skilled attackers who specifically target a certain organization. Preventive measures block the great majority of threats out there, but advanced attackers know how to get around a company's defenses. The better preventive security a company has in place, the harder it will be to get in…but the most highly skilled, highly motivated attackers will still find a way in somehow. That's where detection comes in. Thinking like an attacker If an attacker does get through a company's defensive walls, it's critical to be able detect their presence as early as possible, to limit the damage they can do. There has been no official confirmation of when Sony's actual breach first took place, but some reports say the company had been breached for a year before the attackers froze up Sony's systems and began leaking volumes of juicy info about the studio's inner workings. That's a long time for someone to be roaming around in a network, harvesting data. So how does one detect an attacker inside a network? By thinking like an attacker. And thinking like an attacker requires having a thorough knowledge of how attackers work, to be able to spot their telltale traces and distinguish them from legitimate users. Advanced or APT (Advanced Persistent Threat) attacks differ depending on the situation and the goals of the attacker, but in general their attacks tend to follow a pattern. Once they've chosen a target company and performed reconnaissance to find out more about the company and how to best compromise it, their attacks generally cover the following phases: 1. Gain a foothold. The first step is to infect a machine within the organization. This is typically done by exploiting software vulnerabilities on servers or endpoints, or by using social engineering tactics such as phishing, spear-phishing, watering holes, or man-in-the-middle attacks. 2. Achieve persistence. The initial step must also perform some action that lets the attacker access the system later at will. This means a persistent component that creates a backdoor the attacker can re-enter through later. 3. Perform network reconnaissance. Gather information about the initial compromised system and the whole network to figure out where and how to advance in the network. 4. Lateral movement. Gain access to further systems as needed, depending on what the goal of the attack is. Steps 2-4 are then repeated as needed to gain access to the target data or system. 5. Collect target data. Identify and collect files, credentials, emails, and other forms of intercepted communications. 6. Exfiltrate target data. Copy data to the attackers via network. Steps 5 and 6 can also happen in small increments over time. In some cases these steps are augmented with sabotaging data or systems. 7. Cover tracks. Evidence of what was done and how it was done is easily erased by deleting and modifying logs and file access times. This can happen throughout the attack, not just at the end. For each phase, there are various tactics, techniques and procedures attackers use to accomplish the task as covertly as possible. Combined with an awareness and visibility of what is happening throughout the network, knowledge of these tools and techniques is what will enable companies to detect attackers in their networks and stop them in their tracks. Following the signs Sony may have been breached for a year, but signs of the attack were there all along. Perhaps these signs just weren't being watched for - or perhaps they were missed. The attackers tried to cover their tracks (step 7) with two specific tools that forged logs and file access and creation times - tools that could have been detected as being suspicious. These tools were used throughout the attack, not just at the end, so detection would have happened well before all the damage was done, saving Sony and its executives much embarrassment, difficult PR, lost productivity, and untold millions of dollars. In the case of Hacking Team, the hacker known as Phineas Fisher used a network scanner called nmap, a common network scanning tool, to gather information about the organization’s internal network and figure out how to advance the attack (step 3). Nmap activity on a company internal network should be flagged as a suspicious activity. For moving inside the network, step 4, he used methods based on the built-in Windows management framework, PowerShell, and the well-known tool psexec from SysInternals. These techniques could also potentially have been picked up on from the way they were used that would differ from a legitimate user. These are just a few examples of how a knowledge of how attackers work can be used to detect and stop them. In practice, F-Secure does this with a new service we've just launched called Rapid Detection Service. The service uses a combination of human and machine intelligence to monitor what's going on inside a company network and detect suspicious behavior. Our promise is that once we've detected a breach, we'll alert the company within 30 minutes. They'll find out about it first from us, not from the headlines. One F-Secure analyst sums it up nicely: "The goal is to make it impossible for an attacker to wiggle his way from an initial breach to his eventual goal." After all, breaches do happen. The next step, then, is to be prepared.   Photo: Getty Images

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
