As I write this, the team is cleaning up a ransomware event for a client. The ransom started at 5 bitcoin ($12,760 as of today) and we negotiated down to 3 BTC. The downtime for the client cost much more since it is the end of the month, quarter, and time for payroll. I estimate the total cost to be around $25,000. Not petty cash for most companies.
It is an excellent time for bad guys to attack. Many people use the summer for vacation and/or summer hours. This means small organizations may have little to no tech help. And small organizations are excellent targets.
Please make sure your machines are patched, that you run current versions of software, and have the licensed versions of anti-virus/malware software. Verify your backups are in place and that they work.
If you need help, I can recommend a few IT companies to help. Rocker advises and does not perform this sort of work.
Good luck!
