Month-to-month, a threat labeled as WMA/TrojanDownloader.GetCodec.Gen has climbed two slots in the ranking, being especially prevalent in western and northern Europe. This Trojan converts all audio files found on a computer to the WMA format and adds a field to the header that includes a URL pointing the user to a new codec, claiming that the codec has to be downloaded so that the media file can be read.
Win32/Injector with a share of 0.66% of all detected malware is a newcomer on the threatscape, ranking it in the overall 10th place. Win32/Injector is a generic descriptor that might be applied to any malware that injects code into a running process, often for self-protection by masking its own presence, though an injector may intercept, piggyback or modify legitimate processes for other purposes. Such malware often injects code into Internet browser processes in order to bypass firewall defenses and communicate with a botnet command and control (C&C) server.
