I recently worked with investigative journalists from Yle, attempting to uncover disinformation on social media around the May 2019 European elections. This work was also part of F-Secure’s participation in the SHERPA project, which involves developing an understanding of adversarial attacks against machine learning systems – in this case, recommendation systems on social networks. My […]
As part of the Horizon 2020 SHERPA project, I’ve been studying adversarial attacks against smart information systems (systems that utilize a combination of big data and machine learning). Social networks fall into this category – they’re powered by recommendation algorithms (often based on machine learning techniques) that process large amounts of data in order to […]
This is a rather long blog post, so we’ve created a PDF for you to download, if you’d like to read it offline. You can download that from here. Executive Summary This report explores Brexit-related Twitter activity occurring between December 4, 2018 and February 13, 2019. Using the standard Twitter API, researchers collected approximately 24 […]
I got into social network analysis purely for nerdy reasons – I wanted to write some code in my free time, and python modules that wrap Twitter’s API (such as tweepy) allowed me to do simple things with just a few lines of code. I started off with toy tasks, (like mapping the time of […]
In May of this year, Horizon 2020 SHERPA project activities kicked off with a meeting in Brussels. F-Secure is a partner in the SHERPA consortium – a group consisting of 11 members from six European countries – whose mission is to understand how the combination of artificial intelligence and big data analytics will impact ethics […]
I wanted to create a how-to blog post about creating gephi visualizations, but I realized it’d probably need to include, like, a thousand embedded screenshots. So I made a video instead.
A month and a half ago I posted an article in which I uncovered a series of Twitter accounts advertising adult dating (read: scam) websites. If you haven’t read it yet, I recommend taking a look at it before reading this article, since I’ll refer back to it occasionally. To start with, let’s recap. In my […]
About a week ago, a Tweet I was mentioned in received a dozen or so “likes” over a very short time period (about two minutes). I happened to be on my computer at the time, and quickly took a look at the accounts that generated those likes. They all followed a similar pattern. Here’s an […]
In January 2018, I wrote a couple of blog posts outlining some analysis I’d performed on followers of popular Finnish Twitter profiles. A few people asked that I share the tools used to perform that research. Today, I’ll share a tool similar to the one I used to conduct that research, and at the same […]
F-Secure development teams participate in a variety of academic and industrial collaboration projects. Recently, we’ve been actively involved in a project codenamed SSICLOPS. This project has been running for three years, and has been a joint collaboration between ten industry partners and academic entities. Here’s the official description of the project. “The Scalable and Secure […]
