Also by the end of the crisis, NASA and DOE computer network managers had their choice of vaccines, antidotes and blood tests for the WANK worm. McMahon had released ANTIWANK.COM, a program which killed the worm and vaccinated a system against further attacks, and WORM-INFO.TEXT, which provided a list of worm-infestation symptoms. Oberman's program, called [.SECURITY]CHECK_SYSTEM.COM, checked for all the security flaws used by the worm to sneak into a computer system. DEC also had a patch to cover the security hole in the DECNET account. Whatever the real number of infected machines, the worm had certainly circumnavigated the globe. It had reach into European sites, such as CERN--formerly known as the European Centre for Nuclear Research--in Switzerland, through to Goddard's computers in Maryland, on to Fermilab in Chicago and propelled itself across the Pacific into the Riken Accelerator Facility in Japan.14 NASA officials told the media they believed the worm had been launched about 4.30 a.m. on Monday, 16 October.15 They also believed it had originated in Europe, possibly in France. Wednesday, 18 October 1989 Kennedy Space Center, Florida The five-member Atlantis had some bad news on Wednesday morning. The weather forecasters gave the launch site a 40 per cent chance of launch guideline-violating rain and cloud. And then there was the earthquake in California. The Kennedy Space Center wasn't the only place which had to be in tip-top working order for a launch to go ahead. The launch depended on many sites far away from Florida. These included Edwards Air Force Base in California, where the shuttle was due to land on Monday. They also included other sites, often military bases, which were essential for shuttle tracking and other mission support. One of these sites was a tracking station at Onizuka Air Force Base at Sunnyvale, California. The earthquake which ripped through the Bay area had damaged the tracking station and senior NASA decision-makers planned to meet on Wednesday morning to consider the Sunnyvale situation. Still, the space agency maintained a calm, cool exterior. Regardless of the technical problems, the court challenges and the protesters, the whimsical weather, the natural disasters, and the WANK worm, NASA was still in control of the situation. `There's been some damage, but we don't know how much. The sense I get is it's fairly positive,' a NASA spokesman told UPI. `But there are some problems.'16 In Washington, Pentagon spokesman Rick Oborn reassured the public again, `They are going to be able to handle shuttle tracking and support for the mission ... They will be able to do their job'.17 Atlantis waited, ready to go, at launchpad 39B. The technicians had filled the shuttle up with rocket fuel and it looked as if the weather might hold. It was partly cloudy, but conditions at Kennedy passed muster. The astronauts boarded the shuttle. Everything was in place.
