CHARLOTTE, N.C. -- It has been one year since ransomware took control of Mecklenburg County servers, almost just as long since the Charlotte Housing Authority saw its own cyber attack, and weeks since Atrium announced customer data was accessed.

Malware attacks in the first half of 2018 triples the total number of attacks through all of 2017, according to Securelist.

The chief information security officer for Wells Fargo, Rich Baich, says to help stop cyber security attacks we’ve seen nationally, and in North Carolina, consumers need to begin changing their habits.

“Making sure you practice good, information and security technology hygiene is very important,” Baich said. “So patch your systems, make sure you connect to secure networks, use two-factor authentication."

More than 70 percent of last year's targeted cyber attacks started with email “phishing” attempts, according to Symantec.

That’s the same method used to compromise Mecklenburg County servers.
