CAMBRIDGE, Mass.--(BUSINESS WIRE)--Aug. 14, 2003

Rate of new Blaster worm infections is not decreasing despite

worldwide computer security alerts;

45% of infected machines are now in North America

Akamai Technologies, Inc. (Nasdaq: AKAM), a provider of services that enable the world's leading enterprises and government agencies to extend and control their e-business infrastructure, is tracking the global propagation of the Blaster worm, which began infecting computers on August 11. The virus is designed to spread first to unprotected computers. Beginning Saturday at 12 AM local time, infected computers will launch a targeted denial of service attack against a Microsoft Web property.

"Based on Akamai's network intelligence data, the attack started on August 11th and decreased in intensity as networks filtered worm traffic over the subsequent two days. Over the last 24 hours, however, the trend has changed and the rate of infection is no longer decreasing," said Andy Ellis, chief security architect, Akamai. "Akamai will continue to monitor the worm's progress closely and will be providing updates on its corporate Web site throughout the event."

In addition to offering a full range of content and application delivery solutions, Akamai has critical real-time insight into reliability and performance of the Internet. Akamai's view of the worm's propagation is derived from Akamai's distributed network comprised of more than 14,000 servers in over 1,100 networks in 70 countries. Based on its network intelligence, Akamai believes that infected machines, numbering in the hundreds of thousands as of this afternoon, are located as follows:

  North America:      45%  (United States 38%, Canada 6%)(a) Europe:             27%  (Germany 5%, Spain 3%) Asia-Pacific:       24%  (Korea 11%, China 5%) South America:       4%  (a) (Note: Not all countries and affected areas are represented.)  

Akamai Technologies' Network Operations Command Center (NOCC), located in Cambridge, Massachusetts, has a comprehensive worldwide view of the real-time conditions on the Internet. Akamai's NOCC is currently tracking the movement of the Blaster worm in real time and developing reports on progression of the worm's infestation.
