Peaches Posted September 15, 2009 Report Share Posted September 15, 2009 PandaLabs: Non-Delivery Report Email Spam Rises 2000% In August, 20 percent of spam messages exploited this technique Sep 14, 2009 | 09:24 AMLondon, September 14th, 2009 - In August 2009, PandaLabs recorded a 2000 percent increase in the amount of different NDR spam messages in circulation (compared to the number of samples detected between January and June this year). Twenty percent of global spam monitored by Panda Security uses this technique. An NDR (non-delivery report) is an email automatically sent by mail systems to advise senders of problems delivering their messages. These messages are usually legitimate, but this mail server function is being exploited by spammers to distribute spam, using the sender's real name. The spam content is usually sent as an attachment to the fake non-delivery notice. Although in most cases users have not sent the supposedly undelivered email, they still become curious and open it. darkreading - http://www.darkreading.com/security/antivi...ction=Antivirus Quote Link to post Share on other sites
