Top threats in December: Conficker, PDF Exploits and Spyware Application

<a target="_blank" href=24162</buxus-link>>Win32/Conficker was the topmost threat in the year of 2009 according to ESET ThreatSense.Net® with 9,85% share of all detected malware in December.

<a target="_blank" href=26071,""</buxus-link>>INF/Autorun again placed among the top threats in December 2009 with 7,58%. This detection label is used to describe a variety of malware using the file autorun.inf as a way of compromising a PC. This file contains information on programs meant to run automatically when removable media (USB flash drives and similar devices) are accessed by a Windows PC user. According to ESET the share of this mixture of trojans could be lower in 2010 when Windows 7 will become more popular among users ( containing more security features related to autorun.inf).

<a target="_blank" href=26615,""</buxus-link>>Win32/PSW.OnLineGames (7,16%) is still among the most spreading malware. This is a family of Trojans used in phishing attacks aimed specifically at game-players: this type of Trojan comes with keylogging and (sometimes) rootkit capabilities which gather information relating to online games and participant credentials. Characteristically, the information is sent to a remote PC operated by an intruder. <a target="_blank" href=25307,""</buxus-link>>Win32/Spy.Ursnif.A (0,56%) is a new addition to the threat chart in December. This label describes a spyware application that steals information from an infected PC and sends it to a remote location, creating a hidden user account in order to allow communication over Remote Desktop connections.
