Are you ready to sign your kids up to reverse engineer Android malware?

This is a guest post from Su Gim Goh of F-Secure Labs.

Last Wednesday marked the beginning of our first lecture at the Aalto University (Espoo campus) in Finland for our Reverse Engineering Malware course for the spring 2013 semester. This course expands and continues F-Secure’s longstanding efforts to promote education in information security, which started in 2008 with a course in Malware Analysis and Antivirus Technologies with the Helsinki University of Technology.

Aalto University’s Reverse Engineering Malware course is taught by security researchers from our Security Lab in Helsinki. The program teaches students about what malicious code is, how it can be analyzed, and how to reverse engineer executable code for different platforms, such as Windows and Android.

Towards the end of the course, students are also exposed to more advanced topics, such as understanding the latest techniques in binary obfuscation and exploits. The syllabus is designed to encourage a very hands-on approach to learning reverse engineering. Our security researchers personally craft exercises and lab assignments to help students gain an understanding of how malicious code works, for example by looking for hidden messages in the code (with keys to help them to achieve the goal of the exercise, as seen in the example below).


Do note that F-Secure does not use or write real world malware in our academic courses.  F-Secure strives to positively motivate programmers and includes modules that cover topics like ethics and legal issues in the course to encourage them to use their skills for a good cause – helping to protect the end user.

Over the other side of the world in Kuala Lumpur, Malaysia, where our other Security Lab is located to cater for the Asia Pacific region, we are partnering with Monash University (Sunway Campus) for the first time to develop a similar Malware Analysis syllabus, with a greater focus on the Android platform. The growing dominance of the Android platform in the smartphone market has also led to a tremendous growth in malware targeting devices using that operating system.

In conjunction with the lecturers from the School of Information Technology of the Sunway campus, and several security researchers from F-Secure’s Kuala Lumpur Security Lab, we are developing the syllabus from the ground up with brand new lecture and lab materials to help students whom are active in the security field gain a broader perspective of this field, as well as develop the specialized skills needed for analyzing malware.  Subjects and techniques covered in the lectures and lab sessions include, among others interesting topics, understanding the Android security framework, the operating and file systems, static and dynamic analysis of malware.

For those who are interested in understanding executable code inside out (literally) and are passionate about security, this is definitely the course for you! You can follow along on the Labs’ weblog for updates.

Cyber Monday Mythbusting

It's Cyber Monday, and marketing companies expect online shoppers to flock to websites and apps in order to take advantage of holiday sales. And naturally, this causes concerns about what kind of risks people are taking when they shop online. But F-Secure Security Advisor Sean Sullivan says any security warnings focusing on Cyber Monday are simply part of the hype. “Cyber Monday is no more or less safe than any other day of the year. People just expose themselves to more online threats when they do more stuff online, but that really has nothing to do with Cyber Monday. And people that tell you otherwise aren’t doing you any favors.” So there you have it. On the other hand, Sullivan does point out that holiday shoppers should beware of the extent to which they expose themselves while online shopping, which is becoming more popular during the holidays. Adobe is projecting an eleven percent increase in online spending during the holidays this year, amounting to a whopping 83 billion dollars. So that’s 83 billion dollars that will be up for grabs (compared to just 3 billion on Cyber Monday), so it’s naïve to think that criminals are just going to ignore the opportunity. Last year, F-Secure Labs registered a sharp increase in ransomware detections during November and December, including a 300 percent increase in the Browlock police-themed ransomware family. Sullivan published a recent blog post examining the Crytowall ransomware family, which he says is prevalent during the holiday season but virtually disappears in early January – when people celebrating Orthodox Christmas in Russia begin their holidays. One easy way to protect yourself from ransomware and other online threats while holiday shopping is to be conscious of the threat landscape. Its trends like these that Sullivan pays attention to, and warns others to do the same. “It would be safe to say that people should be worried about ransomware this holiday season, and probably through next year. I expect that we, or at least security researchers, will look back on 2016 as the year of extortion.” For example, even though mobile device are now widespread and used by many people, they’re not necessarily good tools to use for making financial transactions while online shopping. “I use an iPad running Freedome for the vast majority of my online browsing, which works great for me because it’s easy to use and I can bring it with me if I leave the house. And between the security benefits of a VPN and the relatively small amount of malware targeting iOS devices, I feel pretty confident in using it to casually window shop on different websites. But I always use a PC to make actual purchases. I trust that my PC is secure and the actual keyboard makes it easier to enter financial data.” You can find more great advice on how to stay safe while online shopping here.

F-Secure Bringing a totally new Future for the Internet to SLUSH 2015

#SLUSH15 is almost here, and F-Secure’s participating in this year’s event in a big way. There’s going to be a big #smartsecurity announcement about the Internet of Things, as well as a couple of presentations from F-Secure personnel. SLUSH, a well-known exposition for startups in the tech industry, has become a huge international event. Both SLUSH and F-Secure call Helsinki home, so it’s only natural for F-Secure to be an active participant at the annual conference. F-Secure made waves last year after the cybersecurity company hacked the venue’s bathrooms to get people talking about online privacy. Several of the company’s researchers and personnel also put in appearances at last year’s SLUSH, including cyber security expert Mikko Hypponen, and F-Secure’s Executive Vice President, Consumer Security, Samu Konttinen. [youtube] [youtube] And they’re both back this year! This year, Samu will be giving a keynote address on SLUSH’s Silver Stage. His talk is called “Your home, your rules – The internet of what ifs”, and runs from 11:45am to 12:00pm (Helsinki time) on November 11th. Samu’s enthusiasm for topics related to security and online privacy will give people valuable insights into how IoT devices are creating new security challenges, and what people can do to protect themselves. Mikko will be appearing on SLUSH’s Black Stage at 9:25am (Helsinki time) on November 12th, where he’ll deliver a talk called “The Online Arms Race”. Mikko recently did an interview about this same topic for, so you can check that out if you want a quick preview about Mikko’s thoughts on this matter. You can follow all of F-Secure’s SLUSH news by following @FSecure_Sense, @FSecure_IoT, and @FSecure on Twitter.
