future of cyber warfare

3 questions about the future of cyber warfare

“We’re not creative enough when we imagine cyber warfare,” F-Secure Security Advisor Sean Sullivan recently told me. “It’s not kinetic explosions. It could be a guy whose crimeware business has dried up and is looking for new business.”

Over the last week, F-Secure Labs has taken a look at attacks from the “Energetic Bear” hacking group, Havex, which targets the energy sector, and now CosmicDuke, which is aimed at targets in Ukraine, Poland, Turkey, and Russia.

The goal of these attacks seems to be espionage or gathering information up for a buyer, which could be a government. But the methods don’t match the precision and massive investment of manhours that went into an attack like Stuxnet, which was designed to take down Iran’s nuclear capabilities.

“They rely on plausible deniability and using resources that don’t seem to be created specifically for the task,” Sean said. “It matches the modular methodology of what we conventionally think of as crimeware.”

“You look at one element and it looks like crimeware,” said F-Secure Senior Researcher Timo Hirvonen, who wrote the CosmicDuke analysis. “You look at it from a different angle and you say, ‘I’ve never seen it aimed like that before.'”

“The conventional wisdom is that anything related to cyber warfare will be shiny and new,” Sean said. These attacks instead suggest “semi-professionalism”.

Here are three questions Sean is pondering in the wake these attacks:

What do we mean when we say state-sponsored?

“Cyber warfare models real life,” Sean said.  “Some countries have a massive cyber intelligence infrastructure that works from the top down. Others seem to have a more grassroots origin, co-opting existing technologies that seem to be built on existing crimeware.”

He wonders if state-focused campaigns are using malware that isn’t necessarily state-sponsored. “Countries who use troops with black masks and no insignias standing on a peninsula may have the same kind of thing going online.”

Opportunistic and pragmatic governments may be paying people to co-opting technology that exist for international espionage purposes.

He suggests the goals of such attacks may fit into Sun Tzu’s advice from The Art of War: know your enemy.

Armed with information, countries can use soft power to turn allies against each other and dissuade retribution like economic sanctions.

What do we mean by APT — advanced persistent threat?

These attacks are not complex in the way Stuxnet was. And they don’t need to be.

CosmicDuke  — a variant of a malware family that has existed since 2001–  infects by tricking targets into opening either a PDF file which contains an exploit or a Windows executable whose filename makes it look like a document or image file.

Once the target opens the malicious file, CosmicDuke gains access starts collecting information with a keylogger, clipboard stealer, screenshotter, and password stealers for a variety of popular chat, e-mail and web browsing programs. CosmicDuke also collects information about the files on the system, and has the capability to export cryptographic certificates and their private keys. Once the information has been collected, it is sent out to remote servers via FTP. In addition to stealing information from the system, CosmicDuke allows the attacker to download and execute other malware on the system. Pretty standard stuff.

Is the war against crimeware driving criminals to cyber espionage? Or: Could be fighting cybercrime be counterproductive?

“Some of these guys may be working for the government and themselves,” Sean said.

A wave of successes in the international war on cybercrime may be driving criminals to new buyers.

“The talent developed on its own,” he said. “And now there’s a government taking advantage of talent in their borders. Law enforcement has been going after crimeware. But it doesn’t go away. It’s fungible. The talent’s still there it needs to make a buck.”

Sean believes there’s a message in these attacks for everyone.

“It’s not just the NSA that hunts system admins. If you have any sort of credentialed access to important systems, you are a target. Keep calm and secure your stuff.”

He hopes that businesses will recognize that prevention is always the best remedy.

“For IT managers: ask for the security budget you need – and fight for it. There is more evidence than ever that letting cost dictate security is bad management.”

If governments are willing to work with increasingly opportunistic malware authors, risks could grow exponentially.

“Is today’s crimeware botnet, tomorrow’s national security nightmare?” Sean asks. “What happens when these guys get out of jail? I’m sure they won’t let the talent go fallow.”

Cheers,

Sandra

3 Tips on using iPhone Settings for Better Security

Many people feel that some platforms are more secure than others. And while there may be some truth in that, what’s far more common is that operating systems offer users security features that people choose to use, or ignore. As Micke has pointed out in the past, behavior is often more important for security than product features. So someone with an Android device that updates all the software, sets it up to keep the device and data in their control, and knows how to avoid risky behavior that hackers look for will keep their data safer than an iPhone user that’s never even looked at the settings for their device. And based on what we saw at AltConf2016 – a developer event that mirrored Apple’s last WWDC – it looks like many iPhone and iPad users are making some pretty basic security faux pas. So here’s a few tips iPhone and iPad users can use to protect their devices and data. Don’t forget to forget Wi-Fi networks Unlike Android and Windows Phone, iOS devices don’t let you see your Wi-Fi history. It might not seem like it, but periodically cleaning out your Wi-Fi history is important. We’ve shown in the past that many people configure their devices to automatically connect with Wi-Fi hotpots they’ve connected with before. This leaves them exposed to hackers spoofing Wi-Fi hotspots (which is surprisingly simple and inexpensive to do). So if you’re an “auto-connector”, you should always remember to “forget” public Wi-Fi networks that you use in the odd café, hotel, or restaurant you visit. Because iOS devices don’t let you see your network history, you can’t pick and choose old networks you want to forget. So iOS users have two options: either forget a Wi-Fi network before you leave and walk out of range, or do a periodic network reset to clean out your entire network history. Don’t name your device after yourself During AltConf2016, F-Secure set up a Wi-Fi hotspot to see whether or not people would connect to any available free Wi-Fi. And as we’ve seen in the past, people take their Wi-Fi wherever they can get it. While many people connected and disconnected frequently, it was clear that lots of those people seem to name their device’s after themselves – approximately 80% of the devices that connected included a first name as part of the device identifier. And out of that 80%, 70% of them were iOS devices (Android and OS X devices constituted the remaining 30%). Now, hackers won’t really need this information to “pwn” their victims. But little tidbits like these are great for scams that use social engineering. Fraudsters and tricksters can use something as simple as this to manipulate people as part of a larger scam. It’s tough to say why personalizing devices seems more popular among iOS users than their Android/Windows counterparts. And having unique device names helps keep them separate on, say, a family’s Wi-Fi network that can have multiple people using it at any one time. But using initials or some other way to differentiate them is a better way to personalize your device without necessarily giving tech-savvy fraudsters the opportunity to learn something they can use to scam you. Use app restrictions (they're not just for kids) Earlier in the year, F-Secure Security Advisor Sean Sullivan recommended people change their iOS settings to take advantage of the various restrictions you can use. You can check out his blog post about it here, but basically, using iOS’ restrictions can create safeguards against malicious apps or attacks that try to trick your device into sharing information without your knowledge. Attackers use apps and processes that can run without requiring direct action from users (such as cloud storage services) to steal data. It’s something often seen as part of corporate cyber attacks, so it’s especially important to do this if you use your iPhone or iPad for work. And as my colleague pointed out in this recent blog post, you should already be using two-factor authentication and strong, unique passwords. [Image by Kārlis Dambrāns | Flickr]

Yes, Your Voice-Activated IoT Devices Are Always Listening

What's easier than typing, clicking or even swiping left? For most of us, speaking. Until we can get actual USB ports in our brain, our mouths may be the quickest way to make our our desires known to our devices. And as it Internet of Things develops, we're going to be doing more and more talking to machines, including our thermostat, light bulbs and possibly even our drones. Fans of Siri and the Amazon Echo are already familiar with the benefits of a conversational interface. But, as with any new technology that gains widespread adoption, privacy and security concerns are inevitable. We spoke to F-Secure's Cyber Gandalf Andy Patel about what users of voice-activated technology should know as they make the leap into this newer realm of connectivity that has long been imagined by science fiction visionaries from Philip K. Dick to Star Trek's Gene Roddenberry. So are these voice-activated devices listening all the time? Yes. In order for a device to react to a voice command without the user pressing a button to activate the feature, the device must listen all the time. How could this be used against us? If a device streams voice data to a server for processing, a few privacy and security implications arise. If the data is being streamed in an insecure way, it can be intercepted by a third party. If the speech data is stored insecurely, it can become compromised in the case of a data breach. It can also potentially sold to a third party. Speech is processed into text. That text might be stored, it might be associated with its source, and it could also be leaked. When the speech processing service returns data to the device that requested the processing, it could also be intercepted. Are the any real privacy concerns for owners of voice-activated devices? Some companies outsource their speech recognition services and cannot properly account for the processes and collection methods used by those companies. Along those lines, just last year, Samsung TV voice recognition made the news for recording owners' chatter. Voice command systems can also be maliciously hijacked. Last year, a group of French researchers demoed a method for remotely controlling Siri from a distance, using sounds that triggered Siri’s voice control, but that couldn’t be recognized by a human. So what will voice-activated technology look like in five or ten years? Big names are interested in voice control because they attach it to AI and machine learning systems -- which are, in turn, fed by the Big Data they’ve collected -- for an interactive experience. The end goal would be a scenario where you could ask your computer to perform arbitrary tasks in the same manner as on Star Trek.

Traveling and using public wifi - privacy is at risk

Free Wi-Fi is a vacation must, but are we paying with our privacy?

We used to search holiday magazines to find the hotel that offered the biggest pool and then triple check that the hotel has air conditioning. If we were really picky, we wouldn’t look twice at a hotel that didn’t offer cable TV. Now we see the perfect summer holiday in a different light. We can’t possibly leave our smartphones, tablets and laptops behind. A survey by Energy Company E.ON revealed that the most important feature hotels must have to even be considered is free Wi-Fi. Why do we find it so difficult to disconnect ourselves from the digital world? Even when we’re sitting in the beautiful sunshine, sipping on cocktails and splashing in the sea? Partly our digital dependence is practical, of course. The web helps us navigate around our holiday destinations finding the best attractions, the coolest bars and most remote beauty spots. But if we’re honest, many of us would admit that we’re so digitally connected because we don’t want to miss anything happening on Facebook, Instagram, Snapchat, Twitter and all the other social apps filling our electronic wonders. We continue to check in, trying to make our friends jealous by posting the latest update about our perfect holiday. Now that we’ve settled that an internet connection is a top holiday priority, why don’t we just use our phone network? Simple: we’ve all heard the horror story of someone getting crazy high bill after spending just a few days in Spain. So, we’re constantly on the search for a local bar or café that offers free Wi-Fi. It’s a fantastic feeling to be wiser than our internet provider – they can’t spring us with unheard-of charges. But connecting to public Wi-Fi comes with its own risks, and, I would argue, scarier ones than an unexpected post-holiday bill. For example, take a look at this infographic. It shows the personal data that can be intercepted and the risks you face to your privacy when you connect to public Wi-Fi without using a VPN. If the thought alone of anyone being able to snoop on what you do online isn’t enough to want to run away from ever connecting to public Wi-Fi again, then think about the bigger risks. The worst case scenario here is you could become a victim of stalking, receive threats, or have your identity stolen. This might sound farfetched, but with what information you reveal on public Wi-Fi, is it worth the risk? If you use a VPN like Freedome while on public Wi-Fi, all your internet traffic will be encrypted. This means instead of your internet traffic connecting directly to the websites from your device, revealing exactly what you’re doing online to the Wi-Fi provider, the VPN will garble your internet traffic and keep what you’re doing online anonymous. You internet privacy and safety is our biggest concern here, and Freedome will definitely provide that security. But here’s a little extra to boost your internet love and consumption when on holiday abroad: When in another country, you might not be able to stream your favorite content from back home. But with Freedome VPN, you can be “virtually” back in your home country, accessing all your favorite content as if you never left.
