Gumblar at Lemesos

Here we are, gathered in Larnaca (Cypus) for the Security Analyst Summit 2010. Beautiful beaches, gorgeous weather – the first thing coming to mind would be jumping into any of the numerous pools or into the sea and have some fun.

WOULD be indeed. However, what came up instead was malware attacks while trying to login to the hotel’s Wi-Fi network. Gumblar. It was our dear friend Gumblar, variant .x to be precise.

So… did we hit the beaches? No… we helped the hotel IT staff clean up the mess. Now we are at the beach – finally :-)))))))))
