A worldwide cyber-attack has impacted as many as 74 countries and multiple companies, including FedEx.
The BBC reported computers in thousands of locations have been locked by a program that demands $300 in an online currency called Bitcoin.
FOX13 spoke with cyber security expert Ben Caston. He said attacks like this aren't going away.
“It is growing rapidly and you know unless people have updates and things being applied it's going to start affecting a lot more computers," he said.
Countries impacted include the US, UK, Spain, China, Russia, and Italy.
The ransomware is known as WannaCry and other variations of the name.
Caston said a lot of businesses end up paying the ransom to get their information back.
“Paying these fines and paying for their files to get unlocked might be a simple way to go about fixing the problem, but it's only enabling it to continue, for them to create these kind of attacks and viruses and things like that," he said.
FedEx sent FOX13 a statement about the attack saying, "Like many other companies, FedEx is experiencing interference with some of our Windows-based systems caused by malware. We are implementing remediation steps as quickly as possible. We regret any inconvenience to our customers.”
