The same two countries also top the chart when it comes to the sources of spam in Europe.
Most of the spam messages containing malware have been aimed towards the United States and Germany.
The Trojan-PSW.Win32.Tepfer malware family has been appointed as being the most common, three versions being present on the chart, including the password-stealing Trojan-PSW.Win32.Tepfer.cfwf – which is number one.
In the past month, phishing campaigns mostly targeted social networking sites (29%), financial organizations (20%), search engines, and online stores and e-auction sites.
“During the holiday season, Internet users should be cautious about opening emails that allegedly contain notifications from various stores, banks, and other financial systems,” Kaspersky’s Darya Gudkova noted.
“Users are warned against opening suspicious attachments from unknown senders, clicking on links allegedly leading to banking websites, and especially against entering any personal information such as bank card numbers, passwords, or usernames for payment accounts.”
