Colonial Pipeline, a major U.S. fuel pipeline operator, was the target of a May 7 cyberattack that disabled certain computer systems responsible for sustaining pipeline operations.

As a result of the incident, Colonial Pipeline was forced to temporarily halt pipeline operations in order to contain the attack.

Colonial Pipeline is responsible for transporting a “substantial percentage” of fuel on the East Coast of the United States, including gasoline, diesel, jet fuel and other petroleum products, the executive order stated.

The closure of the pipeline caused many people to panic buy gallons of gas which is leaving many gas stations empty.

Multiple states, including Florida, have declared a state of emergency.
