Now to the cyberattack on a major pipeline that supplies nearly half of the fuel to the east coast. The entire network now shut down. An investigation under way. ABC's elwyn Lopez has more. Reporter: This morning, a ransomware attack forcing a shutdown of one of the nation's largest pipelines. The target, colonial pipeline which supplies 45% of fuel to the east coast. Its 5,500-mile network carries gas, diesel and jet fuel from Texas to New Jersey. We have seen attacks on critical infrastructure over the past five years, but nothing of this size and scope, but also it kind of foretells this is what life is likely to be like in the future. Reporter: To contain the threat, the company says it proactively took certain systems offline, temporarily halting all of the pipeline's operations. We look at an incident like this, and realize how vulnerable we are. Reporter: This strike, the latest in cyberattacks in the past five months. Last December, solar winds which provides software to the government and fortune 500 companies, taking a hit after a massive software breach, posing -- reportedly exposing government agency emails to someone wanting to tamper with the Florida water supply took control of the computer systems at a water treatment facility. As for Friday's attack, experts now warning it could lead to an impact at the gas pumps. It's crucial to add this pipeline in service. If it drags on four days, we may start to see some supply challenges. Reporter: Now experts say gas and jet fuel prices will not spike unless the outage lasts more than three days.
