One of the largest criminal ransomware attacks in history has hit more than 200 organizations at the start of the Independence Day according to cybersecurity firm Huntress Labs, NBC News reports.
The attack, believed to have been perpetrated by the prolific ransomware gang REvil, was spread through an international software management company called Kaseya, which services companies that manage internet services for businesses.
At least four of Kaseya’s immediate customers were hacked, said John Hammond, a senior security researcher at Huntress, which is helping with Kaseya’s response. Kaseya’s software works with an unknown number of business, but Huntress has identified 200 businesses infected by the ransomware so far.
