you laugh at my comment, but the sad part is that 2 of the companies were retail store based, and it cost them over $500,000 (ea.) to recover their data, between attorney fees, forensics, and the ransom they paid because the threat actor encrypted their backups.
they were running server 2008R2 and Windows 7 workstations, every server and every workstation was breached, encrypted and essentially destroyed.
one of other 4, was my company, whom I have been bitching at for a year to upgrade this stuff, I had completed about 60% of the windows 10 rollout before Covid hit.
of the devices infected none were the new Windows 2019 servers or Windows 10 Workstations, all the Windows 2008 R2 and Windows 7 devices were infected with ransomware. While we didn't lose a lot of data, we still had to replace over 80 workstations and we 100% lost 6 servers, thankfully they were all historical systems and we have backups, but the fact that it happened is enough.
while it may seem funny, I have been working 16 hours a day every day since June 4 because of this data breach, and it has not been pretty, luckily we have data breach insurance so everything is being covered, and we are replacing everything with shiny new stuff, but I hardly find it laughable.
FBI told us there has been a 6000% uptick in ransomware attacks since Covid Started and they targeting companies with end of life software. XP, 7, server 2003, 2008, and 2012.
