The hackers behind Locky ransomware launched a massive email campaign on Aug. 28, with over 23 million infected emails sent in a 24-hour period, researchers at AppRiver found.
While Locky at one point was thought to be nearly extinct, the virus has continued to pummel all sectors in 2017. It’s one of the most successful ransomware strains launched, as it continues to evolve to evade attempts to crack its code.
Healthcare has been one of Locky’s biggest targets, with hackers launching a massive attack on the industry in August 2016.
