Meanwhile, disheartening news comes from MessageLabs as a result of their monthly e-mail analysis. The firm found that the global ratio of spam in e-mail broke the halfway mark for the first time in May 2003 at 55.1 percent an increase of 38.6 percent over April 2003's figures and an increase of over 40 percent on the year to date, indicating that the majority of e-mail received by business enterprises is now spam.https://o1.qnsr.com/log/p.gif?;n=203;c=204650394;s=9477;x=7936;f=201801171506010;u=j;z=TIMESTAMP;a=20392931;e=i"The volume of spam now facing computer users every day has now far surpassed the point of being a nuisance and is now causing significant productivity losses and IT costs at businesses across the world," noted Mark Sunner, chief technology officer at MessageLabs.
Furthermore, May saw viruses increase by 47.4 percent over the previous month, with the spread of two significant viruses, "Fizzer" and "Sobig.B" (aka "Palyh"), as big contributors. Analysis from http://www.centralcommand.com Central Command, Inc. echoes MessageLabs' findings:
"In its short period of existence [discovered on May 18, 2003], Worm/Palyh infected thousands of users worldwide outpacing Worm/Klez.E as the number one confirmed virus for May 2003," said Steven Sundermeier, product manager of Central Command, Inc.
Sundermeier adds, "Worm/Palyh was written very deceitfully, as it arrives masquerading as an e-mail sent from the Microsoft Support Department. Users should ask themselves 'why would the technical support team at Microsoft send me an unsolicited e-mail with a movie28.pif file attachment?'"
Making its debut in the Dirty Dozen is Worm/Fizzu.A, is an Internet worm that proliferates through e-mail and over various file-sharing programs. "We are seeing more and more viruses coded to spread over Peer-2-Peer (P2P) applications like Kazaa. Nine out of ten times the P2P worm will copy itself under enticing filenames like password cracked software programs, downloaded movies or games or are pornographic themed-based. The bottom line is that programs like Kazaa are opening gapping security holes within a corporate infrastructure," warns Sundermeier.
