Security information from mi2g revealed a more sinister view of October, with the company calling the month one of the worst for spam proliferation. The economic damage caused by spam worldwide as measured in terms of denial of service and productivity losses has reached $10.4 billion in October, mi2g found.https://o1.qnsr.com/log/p.gif?;n=203;c=204650394;s=9477;x=7936;f=201801171506010;u=j;z=TIMESTAMP;a=20392931;e=iDenial of service attacks caused by spam factories operating within the U.S., Russia, Ukraine and China as well as hijacked home computers have been escalating since the summer. Internet service providers in numerous countries reported overwhelming spam and spam generating malware [define] attacks that have significantly degraded network capacity.
The overloaded inbox problem is so great that a study from Quris identified a backlash against companies that have poor e-mail practices. An overwhelming 80 percent of the nearly 1,700 survey respondents indicated that they have stopped reading permission-based e-mails from some companies because too much of the material is irrelevant.
E-marketers have to learn the delicate balance between information and inundation. Nearly half (45 percent) of the Quris respondents revealed that they have stopped doing business with at least one company because of poor e-mail practices, and more than two-thirds (68 percent) cite excessive frequency as their biggest complaint about permission e-mail programs.
John Funk, CEO of Quris, recognizes the pitfalls of online marketing, and explains that managing customer relationships often requires a deep understanding of the consumer's behavioral patterns in order to pick-up on the nuances of whether a consumer is disengaged or dissatisfied. "And, if you miss those nuances, this research shows that it can lead to the loss of a customer, not just an unsubscribe from the offending e-mail."
Permission-based marketers lose readers through other methods too. A Responsys, Inc. survey revealed that more than three-quarters (77 percent) of respondents identified spam and e-mail filters as the primary obstacle to effective permission-based email marketing, followed closely by e-mail inbox clutter at 50 percent.
"Clearly, today's marketers are facing greater deliverability challenges, as consumers, legislators, and service providers respond to an increase in spam e-mail traffic," said Helen Roberts, chief operating officer of Responsys, Inc.
On the virus and worm front, mi2g found that the October 2003 damage was $8.5 billion and hacker damage from verifiable overt digital attacks in October was significantly below $1 billion worldwide.
"In the beginning we thought that hackers were more damaging than malware and malware was more damaging than spam," said DK Matai, executive chairman, mi2g. "October has shown the reverse to be true."
Central Command, Inc. identified Worm/Sober as the newest annoyance, and Worm/Gibe.C moved up the list to replace Worm/Sobig.F as the most prevalent offender.
"With Worm/Sobig.F reports dropping off substantially, the month of October had a changing of the guard on top of the chart in favor of Worm/Gibe.C," said Steven Sundermeier, vice president of products and services at Central Command, Inc. "Much of Worm/Gibe.C's success can be directly attributed to its Microsoft-styled e-mail. Users need to understand that Microsoft does not send attachments over e-mail."
