August spam report from Symantec.

Symantec : 08 August, 2007  (Technical Article)
Latest Symantec report reveals that spam remains at a level of two-thirds of all e-mail handled.
Symantec has released its State of Spam Report for August 2007, highlighting the continuation of the trend for Excel and zip file dependent spam replacing image spam, as security filters continue to dent hinder the spread of image-based spam. While image spam recorded its lowest percentage of total spam ever in July, at a mere 8% (down from 52% at its peak in January), PDF spam has continued to increase and in July accounted for up to 8% of all spam.

PDFs are not the only favoured spam attachments either, in July Symantec observed spammers using other attachments to promote stock and pharmaceutical spam. As image spam is increasingly difficult to get through filters, spammers are looking for alternative methods to peddle their wares, and have begun using Microsoft Excel and Zip files to avoid detection. The use of increasingly disparate attacks indicates just how committed spammers are to evading antispam filters.

Other notable statistics from the report include:.

* Overall spam levels remain consistent at around 66 per cent of all emails.
* Greeting card spam remains a favourite, with over 250 million messages recorded.
* Spam containing Chinese domains saw a significant spike in July.
