An ounce of prevention: Anticipating online threats in F-Secure Labs

This is a guest post from Karmina, an expert from F-Secure Labs. Enjoy!

Little is known about the team in the F-Secure Labs that focuses on tracking down threats. Usually, those contacting the Labs are looking for solutions such as detections and removals. Though mostly working in the background, I’m proud to be part of that team that deals with preventing threats from infecting further.

Proactive protection is my daily mantra. The usual question that I ask when analyzing a threat is where did it come from? If we are able to determine the source and block it from there, then it won’t proceed to infect your computer. My job is to spot threats and track down their possible sources, from social networks to email spams to application stores. Then I need to understand the threat’s behavior and how it spreads. They usually leave distinct trails and have certain characteristics that make them identifiable. It’s fun, in the sense that I feel like I’m a detective trying to uncover something. It’s like building a puzzle where I examine the pieces and put them together to see the bigger picture.

In the Labs, teamwork is important. I provide the information that I gather to other teams so they can build solutions such as website ratings, detections, and removals. We work together toward a common goal: to protect you and provide online safety. From blocking malicious URLs that push information-thieving wares into computers, to scouring application stores worldwide for Trojans disguised as interesting apps, we try to catch them all and protect the users.

Considering that I didn’t plan to get into this field, I’d have to say that I enjoy doing this. Due to constantly evolving threats, I learn a lot of new things daily. I feel fulfilled when I uncover a mystery. I’m glad I ended up in the online security field. My career is also why I’ve had the chance to live in three different countries. I get to see the world while doing interesting work. All in all, not bad!

graveyard, RIP Flash, Is Flash dead

RIP Flash? Has Chrome signed Flash’s death warrant?

The first day of September may go down in internet security history -- and not just because it's the day when F-Secure Labs announced that its blog, which was the first antivirus industry blog ever, has moved to a new home. It's also the day that Google's Chrome began blocking flash ads from immediately loading, with the goal of moving advertisers to develop their creative in HTML5. Google is joining Amazon, whose complete rejection of Flash ads also begins on September 1. "This is a very good move on Amazon’s part and hopefully other companies will follow suit sooner than later," F-Secure Security Advisor Sean Sullivan wrote in August when Amazon made its announcement. "Flash-based ads are now an all-too-common security risk. Everybody will be better off without them." Last month, Adobe issued its 12th update in 2015 for the software addressing security and stability concerns. An estimated 90 percent of rich media ads are delivered through Flash. Having the world's largest online retailer reject your ad format is a significant nudge away from the plugin. But it would be difficult to overstate the impact of Chrome actively encouraging developers to drop Flash. About 1 out of every 2 people, 51.74 percent, who access the internet through a desktop browser do it via Chrome, according to StatCounter. This makes it the world's most popular web interface by far.   Facebook's Chief Security Officer has also recently called for the end of Flash and YouTube moved away from the format by default in January. “Newer technologies are available and becoming more popular anyway, so it would really be worth the effort to just speed up the adoption of newer, more secure technologies, and stop using Flash completely," F-Secure Senior Researcher Timo Hirvonen told our Business Insider blog. So what's keeping Flash alive? Massive adoption and advertisers. “Everyone in every agency’s creative department grew up using Adobe’s creative suite, so agencies still have deep benches of people who specialize in this,”Media Kitchen managing partner Josh Engroff told Digiday. “Moving away from it means new training and calibration.” And Flash does have some advantages over the format that seems fated to replace it. "HTML5 ads may be more beautiful, and are perceived to be more secure, but the files can be a lot larger than Flash," Business Insider's Laura O'Reilly wrote. In markets, stability can breed instability and it seems that our familiarity and reliance on Flash has resulted in unnecessary insecurity for our data. Has Flash hit its moment when its dominance rapidly evaporates? We can have hope. "I sincerely hope this is the end of Flash," Timo told us. Cheers, Sandra [Image by Sean MacEntee | Flickr]

hacking team, hack like a champion, why hacking team matters

3 reasons the Hacking Team story matters from Mikko Hypponen

Hacking is in the news. The U.S. recently disclosed that it was the victim of what may the biggest, most consequential hack ever. We hacked some politicians. And a group called "Hacking Team" was hacked itself. Brian Krebs reports: Last week, hacktivists posted online 400 GB worth of internal emails, documents and other data stolen from Hacking Team, an Italian security firm that has earned the ire of privacy and civil liberties groups for selling spy software to governments worldwide. The disclosure of a zero-day vulnerability for the Adobe Flash Player the team has used has already led to a clear increase of Flash exploits. But this story has a larger significance, involving serious questions about who governs who can buy spyware surveillance software companies and more. Our Chief Research Office Mikko Hyppönen has been following this story and tweeting insights and context. Reporters from around the world have asked him to elaborate on his thoughts. Here's a look at what he's been telling them 1) What is your opinion about the Hacking Team story? This is a big story. Companies like Hacking Team have been coming to the market over the last 10 years as more and more governments wanted to gain offensive online attack capability but did not have the technical know-how to do it by themselves. There's lots of money in this business. Hacking Team customers included intelligence agencies, militaries and law enforcement. Was what Hacking Team was doing legal? Beats me. I'm not a lawyer. Was what Hacking Team was doing ethical? No, definitely not. For example, they were selling hacking tools to Sudan, whose president is wanted for war crimes and crimes against humanity by the International Criminal Court. Other questionable customers of Hacking Team include the governments of Ethiopia, Egypt, Morocco, Kazakhstan, Azerbaijan, Nigeria and Saudi Arabia. None of these countries are known for their great state of human rights. List of Hacking Team customers: Australia - Australian Federal Police Azerbaijan - Ministry of National Defence Bahrain - Bahrain Chile - Policia de Investigation Colombia - Policia Nacional Intelligencia Cyprus - Cyprus Intelligence Service Czech Republic - UZC Cezch Police Ecuador - Seg. National de intelligencia Egypt - Min. Of Defence Ethiopia - Information Network Security Agency Honduras - Hera Project - NICE Hungary - Special Service National Security Kazakstan - National Security Office Luxembourg - Luxembourg Tax Authority Malaysia - Malaysia Intelligene Mexico - Police Mongolia - Ind. Authoirty Anti Corruption Morocco - Intelligence Agency Nigeria - Bayelsa Government Oman - Excellence Tech group Oman Panama - President Security Office Poland - Central Anticorruption Bureau Russia - Intelligence Kvant Research Saudi Arabia - General Intelligence Presidency Singapore - Infocomm Development Agency South Korea - The Army South Korea Spain - Centro Nacional de Intelligencia Sudan - National Intelligence Security Service Thailand - Thai Police - Dep. Of Correction Tunisia - Tunisia Turkey - Turkish Police USA - FBI Uzbekistan - National Security Service 2) What happens when a company of this kind is a victim of an hacking attack and all of its technology assets are published online?  This was not the first time something like this happened. Last year, Gamma International was hacked. In fact, we believe they were hacked by the same party that hacked Hacking Team. When a company that provides offensive hacking services gets hacked themselves, they are going to have a hard time with their customers. In the case of Hacking Team, their customer list was published. That list included several secretive organizations who would rather not have the world know that they were customers of Hacking Team. For example, executives of Hacking Team probably had to call up the Russian secret intelligence and tell them that there's been a breach and that their customership was now public knowledge. The Hacking Team leak also made at least two zero-exploits public and forced Adobe to put out emergency patches out for Flash. This is not a bad thing by itself: it's good that unknown vulnerabilities that are being exploited become public knowledge. But Adobe probably wasn't happy. Neither was New York Times, as they learned that Hacking Team was using a trojanized iOS app that claimed to be from New York Times to hack iPhones. 3) Is it possible to be protected from malware provided by companies like Hacking Team? Yes. We've added detection for dozens of Hacking Team trojans over the years. Hacking Team had a service where they would update their product to try to avoid signature-based antivirus detections of their programs. However, they would have much harder time in avoiding generic exploit detections. This is demonstrated by their own internal Wiki (which is now public). Let me attach a screenshot from their Wiki showing how we were able to block their exploits with generic behavioural detection: Cheers, Sandra [Image by William Grootonk | Flickr]

adobe flash, uninstall, auto-update, click-to-play

3 ways to make Adobe Flash less annoying and/or risky

Time to update Adobe Flash if you use it. So if you do, do it now. Of course, it always feels like time to update Flash. As an internet user, it's become all of our collective part-time job. It's a reminded that while the software is free, your time isn't. This particular update was necessitated by an event you may have heard about. "The flaw was disclosed publicly over the weekend after hackers broke into and posted online hundreds of gigabytes of data from Hacking Team, a controversial Italian company that’s long been accused of helping repressive regimes spy on dissident groups," Brian Krebs explained. The Hacking Team hack raised interesting questions about government surveillance and helped rattle nerves this week as computer systems kept planes out of the air and shut down the New York Stock Exchange -- freak incidents that are completely unrelated, according to disclosures thus far. But it doesn't take events like this remind us Flash exploits are so common that they're part of the business model of criminal operations like the Angler exploit kit. The key to security is always running the latest version of everything. So how do you get yourself out of the business of constantly mitigating Adobe Flash risks? Here are three ways. 1. Quit it. This is Brian Krebs' solution. He's lived without it for more than a month as an experiment. "It is among the most widely used browser plugins, and it requires monthly patching (if not more frequently)," Krebs said. And did he notice life without it? "...not so much." So instead of updating, you can just get rid of it. 2. Auto-update. If you're going to keep it, this is the minimum precaution our Security Advisor Sean Sullivan recommends. This will make sure you're getting all the updates and will prevent you, hopefully, from being tricked into downloading malware posing as an update. So turn those "background upgrades" on. 3. Click-to-play. If you're doing number 2, you probably want to do this too. Click-to-play means Flash elements run when you tell them to. Here's how to do it in all your browsers. Not only does this expose you to fewer risks, it makes the internet less annoying and can make your browser quicker. So why not? So what did you choose? Let us know in the comments. Cheers, Jason
