Scammers are targeting Louisville area travelers who were trying to fly during last week's major technology outage that impacted several airlines and businesses across the country.

All systems were down at branches across Jefferson County after hackers installed the malicious software, locking files and demanding money. 

All branches have been closed since Monday after a ransomware attack.

The outage appeared to stem partly from a software update issued by CrowdStrike, a cybersecurity company that detects and block hacking threats.
