A successful ransomware attack on a single company has spread to at least 200 organizations and likely far more, according to cybersecurity firm Huntress Labs, making it one of the single largest criminal ransomware sprees in history.
The attack, first revealed Friday afternoon, is believed to be affiliated with the prolific ransomware gang REvil and perpetuated through Kaseya, an international company that remotely controls programs for companies that, in turn, manage internet services for businesses.
Kaseya announced Friday afternoon it was attacked by hackers and warned all its customers to immediately stop using its service. Nearly 40 of its customers were hacked, Kaseya said late Friday night.
Since those Kaseya customers manage hundreds or thousands of businesses, it is unclear how many will fall victim to ransomware over the weekend. But the number's at least already around 200, said John Hammond, a senior security researcher at Huntress, which is helping with Kaseya's response. That number expected to rise.
