Adware and Trojans Remained Major Threats in April
Adware was the most active item of malware accounting for 27% of the infections in April 2007. The other category, trojans accounted for 25% also causing a large number of infections. Adware intercepts Internet activity of users such as how many pages they visited or words they searched. The information then helps it to display ads.
Adware disguises as an actual tool and is therefore easy to distribute. Users tend to be slow in removing it, as they often do not know the risk adware entails on user privacy. This is the main reason why cyber crooks widely distribute adware, explained Luis Corrons, Technical Directors of PandaLabs. Home.nestor published this in news on May 3, 2007.
BitDefender Labs' report for April 2007 notified that mass e-mails carried malicious worms -Zafi.B and Netsky.P - that struggled to capture the top positions in the malware list with 10% and 8% of all detections, respectively.
The report also said that Trojan.Peed variants continued to stay among the Top Ten. At the same time Trojan downloaders of every kind were in the sixth spot with a significant 3.80% of total infections.
PandaLabs' April 2007 report has also rated trojans as another prevailing threat. This malware has steadily increased the number of incidents over the recent months. In fact during the first three months of 2007, trojans had been the most prevalent piece of malware.
The active state of trojans has been due to two primary reasons. trojans are most helpful in stealing confidential user information like bank account, credit card details and even e-mail account to send spam to. Fraudsters then turn the information to make profits. trojans are also a prudent technique to steal such data in comparison to phishing, Corrons added. Home.nestor published Corrons' comments in news on May 3, 2007.
PandaLabs' top ten list has many new malwares like Cookie/Instadia, Trj/KillAV.FW, JS/Downloader.NOE, Trj/Clicker.ZJ, Trj/Agent.DIL, and Adware/Spylocked.
Some malware that dropped from their previous position were W32/Brontok.H.worm, W32/Sdbot.ftp.worm, W32/Puce.E.worm, and Trj/KillAV.FG.
