In June, the regular monthly report mapping the most widespread computer threats has shown several emerging trends. One of the top threats spreading across almost in all European counties is a trojan infecting websites. Technically, it is a script injected into web pages, which automatically redirects visitors to IFRAME-infected websites, from which the script downloads and executes additional malicious code to unprotected computers.
The threat, classified by ESET as JS/TrojanDownloader.Pegel.BR, has claimed the fifth position in the global ranking, gaining a share of 2.29% of all computer threats detected on the computers of users of ESET NOD32 Antivirus and ESET Smart Security products. This result is based on data provided by the ESET ThreatSense.Net® statistical system.
The variants of the Win32/Conficker worm remain the most frequently occurring threat with a share 9.79%. One interesting thing about Conficker is its extremely high infection share in Ireland and Slovenia accounting for almost one third of all malware detected in the respective countries. Gaining high global shares are also the INF/Autorun class of threat (6.57%) and Win32/PSW.OnLineGames (4.26%). The fourth position is occupied by trojan variants from the Win32/Agent family, stealing sensitive user data from infected users (4.26%).
