San Carlos, California – (The Hosting News) – March 6, 2006 – Email spam volumes rose in February according to data gathered by Postini, a leader in
Integrated Message Management.
Postini is reporting that spam volumes and
encryption volumes were on the rise, viruses returned to normal levels, while IM
attacks were down during the month of February. Postini processed over 22
billion emails in February and found that after blocking 14 billion emails as
DHA’s (directory harvest attacks), malicious attacks and email to invalid
recipients, spam totaled just over 4 billion, an increase of two percent
compared to January, bringing the total amount of spam quarantined to 73
percent for the month.
Postini also filtered 2.2 million instant
messaging (IM) conversations in February, stopping such IM worms as FakeMSN,
Lamo.Worm and Loxbot. Unchecked, these IM worms can install spyware, adware,
keystroke loggers, and root kits on victims’ PCs.
Spam was most prevalent on February 18, with 150 million messages
quarantined, accounting for 82 percent of all messages stopped.
Andrew Lochart, Senior Director of Marketing for Postini commented on the findings, ”The increase in spam was due to an increase in tax preparation offers and other financial service offerings that are more prevalent as we approach April 15.”
Postini measurements show that inbound TLS encryption volumes grew slightly from 6.5% percent of all legitimate inbound traffic to 7.0% percent, and outbound TLS volumes grew from 1.5 percent of all messages to nearly 3 percent, indicating the continued adoption of encryption by customers.
While spam was on the rise, viruses returned to their normal level of 1.5 percent of all email in February, with Postini stopping a total of 40,185,146 viruses. Even the “mywife” virus (aka “kamasutra,” aka “nyxem”), which on February 3 threatened to delete files on infected computers, ranked only eighth on Postini’s top ten viruses for the month.
Postini protected its customers from more than 19 million DHAs, a 47 percent decrease compared to January’s 29 million DHAs. Legitimate email as a percentage of total SMTP connections remained virtually unchanged from January to February.
Only 15.5 percent of all messages were legitimate email.
