Whether it is set to continue remains to be seen. “This is bad news,” says Diego d’Ambra, CTO of SoftScan. “The spam highs normally seen in the summer are bought about by the low levels of normal business email as many people are away from work taking their summer holiday. This time levels of legitimate email have stayed the same and instead the spike is purely due to a marked increase of nearly four percent in spam.”
Virus levels have remained low during October accounting for just 0.41% of email scanned by SoftScan, with phishing still remaining the predominant threat. The continuing release of new stration (warezov) variants has pushed it into the top 5 families, with an outbreak taking place yet again today.
Finally, Trojan.Small-382, part of the haxdoor (bzub) family, is also prevalent at this time. This malware typically targets Germany, but is now also targeting Denmark and Sweden. Normally spammed to recipients, it is very quickly hitting a large number of mailboxes.
Top 5 viruses in October were:
1 phishing: 66.40%
2 small: 10.04%
3 stration: 8.57%
4 netsky: 4.22%
5 downloader: 2.80%
