By the numbers: The REvil ransomware attack

Cybercriminals linked to the hacker group allegedly responsible for an attack on meatpacker JBS have struck again.

Catch up quick: The hackers infiltrated businesses large and small in at least 17 countries, according to Aryeh Goretsky, a cybersecurity researcher with ESET.

By the numbers: Researchers are still determining the full extent of the damage, but here’s what we know so far: 

• The malicious actors claim that 1 million computers have been affected — although that's likely "an enormous overestimate," per WSJ.
• The ransom for a global fix is $70 million, or anywhere between $25,000 and $5 million apiece if victims want to pay separately.

The criminals facilitated their global attack largely through software made by Kaseya. 

• Up to 1,500 firms in Kaseya’s customer chain were impacted, CEO Fred Voccola tells Reuters.
