Earlier this month, FortiGuard Labs researchers published findings about a malware campaign exploiting a PowerPoint vulnerability. Cybercriminals, however, are equal opportunity exploiters, so just recently an interesting targeted malware campaign was found to be using another document vulnerability. Only this time, it’s a Hangul Word Processor (HWP) document leveraging the already known CVE-2015-2545 Encapsulated PostScript (EPS) vulnerability. [Read More]

We recently received a URL through Skype that caught our attention. It was a link belonging to LinkedIn, with our Skype ID as a parameter at the end of the URL.   Usually, people would be wary when they receive links that look somewhat suspicious. But this link is from LinkedIn, the world’s largest networking site, so it would easy for anyone receiving this to quickly dismiss any thought of it being harmful. And the convincing personalized Skype ID at the... [Read More]

The main issue with Hack.Lu this year was that there were too many interesting things in parallel: interesting talks, workshops, CTF... :) Talks 19 year old Filippo Valsorda talked about the setup of (heartbleed testing website) and his surprise at how many requests the website got.

His tools to run a fake FinFisher server... [Read More]

A couple of days back, a game of Nerd Truth or Dare in the lab led to the shocking revelation that most of us were using our Facebook/Twitter accounts mainly to keep up with security blogs. Personally, being a twitter non-conformist until recently, I even created a twitter account for this sole purpose. And that led to the realization that FortiGuard Labs need to 'get with it' too. So here's introducing our Facebook and Twitter pages for your ease of following us. If you, like us, have tried every RSS aggregator there is under the sun, have been... [Read More]

In the past month changes in the SpyEye botnet kit have more or less stopped, after a very busy year in which many new versions were released. I was recently looking at all of the information I have from testing and analysis of these versions, when it occured to me that this lull in activity would be a good time to put some organized results together. Then when SpyEye returns, in some mutant, Zbot like form, we will have something like a guide to its workings, which should be useful. A good place to start this process is with the SpyEye botnet...

In January 2010, the Fortinet’s FortiGuard Labs threat researchers issued a report outlining their predictions for The Top 10 Security Trends for 2010. Now that we’re midway through the year, we thought it would be interesting to see how right (or wrong) we were and if anything completely unexpected has come up along the way. The following report spells out the trends the team predicted at the beginning of the year and concludes with comments on where each threat exists today. 1) Security, Virtually Speaking **January 2010: **“Preventing...
