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

Safer Internet Day

What are your kids doing for Safer Internet Day?

Today is Safer Internet Day – a day to talk about what kind of place the Internet is becoming for kids, and what people can do to make it a safe place for kids and teens to enjoy. We talk a lot about various online threats on this blog. After all, we’re a cyber security company, and it’s our job to secure devices and networks to keep people protected from more than just malware. But protecting kids and protecting adults are different ballparks. Kids have different needs, and as F-Secure Researcher Mikael Albrecht has pointed out, this isn’t always recognized by software developers or device manufacturers. So how does this actually impact kids? Well, it means parents can’t count on the devices and services kids use to be completely age appropriate. Or completely safe. Social media is a perfect example. Micke has written in the past that social media is basically designed for adults, making any sort of child protection features more of an afterthought than a focus. Things like age restrictions are easy for kids to work around. So it’s not difficult for kids to hop on Facebook or Twitter and start social networking, just like their parents or older siblings. But these services aren't designed for kids to connect with adults. So where does that leave parents? Parental controls are great tools that parents can use to monitor, and to a certain extent, limit what kids can do online. But they’re not perfect. Particularly considering the popularity of mobile devices amongst kids. Regulating content on desktop browsers and mobile apps are two different things, and while there are a lot of benefits to using mobile apps instead of web browsers, it does make using special software to regulate content much more difficult. The answer to challenges like these is the less technical approach – talking to kids. There’s some great tips for parents on F-Secure’s Digital Parenting web page, with talking points, guidelines, and potential risks that parents should learn more about. That might seem like a bit of a challenge to parents. F-Secure’s Chief Research Officer Mikko Hypponen has pointed out that today’s kids have never experienced a world without the Internet. It’s as common as electricity for them. But the nice thing about this approach is that parents can do this just by spending time with kids and learning about the things they like to do online. So if you don’t know what your kids are up to this Safer Internet Day, why not enjoy the day with your kids (or niece/nephew, or even a kid you might be babysitting) by talking over what they like to do online, and how they can enjoy doing it safely.

Virdem malware, old viruses, Malware Museum

Step back in time to when hackers were just having fun

What's so fun about old malware? In just four days more than a hundred thousand people have visited The Malware Museum -- an online repository of classic malware, mostly viruses, that infected home computers in the 1980s and 90s. Working with archivist Jason Scott, Mikko Hyppönen -- our Chief Research Officer -- put together 78 examples finest/worst examples of old-school malware that includes emulations of the infections with the destructive elements removed so you can enjoy them safely. "I only chose interesting viruses," Mikko told BBC News. The result is "nerdy nostalgia," says PC Magazine's Stephanie Mlot. The exhibits feature clunky ASCII graphics, pot references and obscure allusions to Lord of the Rings. While an early ancestor of ransomware like Casino was willing to ruin your files and call you an "a**hole," it wasn't trying to extort any cash out of you. That's because the creators of these early forms of digital vandalism were amateurs in the truest sense of the world. They did it for the love of mayhem. We long for the days of "happy hackers," as Mikko calls them, because the malware landscape today is so ominous. "Most of the malware we analyze today is coming from organized criminal groups... and intelligence agencies," Mikko explained. To keep the memories of the good old days alive, we're going to make t-shirts celebrating some classic malware. And we'd like you to choose which viruses we should commemorate. CRASH V SIGN FLAME CASINO PHANTOM (Image via @danooct1) [polldaddy poll=9302985] If you appreciate the Museum, Mikko asks that you contribute to the Internet Archive. You can learn more about Malware from Mikko's Malware Hall of Fame. Cheers, Sandra

Kids need better protection – An open letter to developers and decision makers

Tuesday February 9th is Safer Internet Day this year. An excellent time to sit down and reflect about what kind of Internet we offer to our kids. And what kind of electronic environment they will inherit from us. I have to be blunt here. Our children love their smartphones and the net. They have access to a lot of stuff that interest them. And it’s their new cool way to be in contact with each other. But the net is not designed for them and even younger children are getting connected smartphones. Technology does not support parents properly and they are often left with very poor visibility into what their kids are doing on-line. This manifests itself as a wide range of problems, from addiction to cyber bullying and grooming. The situation is not healthy! There are several factors that contribute to this huge problem: The future’s main connectivity devices, the handhelds, are not suitable for kids. Rudimentary features that help protect children are starting to appear, but the development is too slow. Social media turns a blind eye to children’s and parents’ needs. Most services only offer one single user experience for both children and adults, and do not recognize parent-child relationships. Legislation and controlling authorities are national while Internet is global. We will not achieve much without a globally harmonized framework that both device manufacturers and service providers adhere to. Let’s take a closer look at these three issues. Mobile devices based on iOS and Android have made significant security advances compared to our old-school desktop computers. The sandboxed app model, where applications only have limited permissions in the system, is good at keeping malware at bay. The downside is however that you can’t make traditional anti-malware products for these environments. These products used to carry an overall responsibility for what happens in the system and monitor activity at many levels. The new model helps fight malware, but there’s a wide range of other threats and unsuitable content that can’t be fought efficiently anymore. We at F-Secure have a lot of technology and knowledge that can keep devices safe. It’s frustrating that we can’t deploy that technology efficiently in the devices our kids love to use. We can make things like a safe browser that filters out unwanted content, but we can’t filter what the kids are accessing through other apps. And forcing the kids to use our safe browser exclusively requires tricky configuration. Device manufacturers should recognize the need for parental control at the mobile devices. They should provide functionality that enable us to enforce a managed and safe experience for the kids across all apps. Privacy is an issue of paramount importance in social media. Most platforms have implemented good tools enabling users to manage their privacy. This is great, but it has a downside just like the app model in mobile operating systems. Kids can sign up in social media and enjoy the same privacy protection as adults. Also against their parents. What we need is a special kind of child account that must be tied to one or more adult accounts. The adults would have some level of visibility into what the kid is doing. But full visibility is probably not the right way to implement this. Remember that children also have a certain right to privacy. A good start would be to show whom the kid is communicating with and how often. But without showing the message contents. That would already enable the parents to spot cyberbullying and grooming patterns in an early phase. But what if the kids sign up as adults with a false year of birth? There’s currently no reliable way to stop that without implementing strong identity checks for new users. And that is principally unfeasible. Device control could be the answer. If parents can lock the social media accounts used on the device, then they could at the same time ensure that the kid really is using a child account that is connected to the parents. The ideas presented here are all significant changes. The device manufacturers and social media companies may have limited motivation to drive them as they aren’t linked to their business models. It is therefore very important that there is an external, centralized driving force. The authorities. And that this force is globally harmonized. This is where it becomes really challenging. Many of the problems we face on Internet today are somehow related to the lack of global harmonization. This area is no exception. The tools we are left with today are pretty much talking to the kids, setting clear rules and threatening to take away the smartphone. Some of the problems can no doubt be solved this way. But there is still the risk that destructive on-line scenarios can develop for too long before the parents notice. So status quo is really not an acceptable state. I also really hope that parents don’t get scared and solve the problem by not buying the kids a smartphone at all. This is even worse than the apparent dangers posed by an uncontrolled net. The ability to use smart devices and social media will be a fundamental skill in the future society. They deserve to start practicing for that early. And mobile devices are also becoming tools that tie the group together. A kid without a smartphone is soon an outsider. So the no smartphone strategy is not really an alternative anymore. Yes, this is an epic issue. It’s clear that we can’t solve it overnight. But we must start working towards these goals ASAP. Mobile devices and Internet will be a cornerstone in tomorrow’s society. In our children’s society. We owe them a net that is better suited for the little ones. We will not achieve this during our kids’ childhood. But we must start working now to make this reality for our grandchildren.   Micke
