The Robin Hoods of the Internet

"Coming to BlackMatter Ransomware strain, a Cybersecurity firm named Recorded Future has offered some intelligence related to the malware.
It was discovered that the said ransomware gang only targets corporate networks that have a minimum 500 to 15,000 hosts on a network and have an annual revenue earnings of $100 million, and operate in the US, UK and Canada and Australian regions.
Interestingly, the gang only targets firms that are in a position to pay $100,000(similar to REvil and DarkSide ransomware group demands) and targets operating systems and architecture that include Linux, Windows, VMware, and Network Attached Storage (NAS) produced by Synology, FreeNAS, OpenMediaVault, and TrueNAS.
Good news is that the said file encrypting gang never attacks hospitals, firms belonging to defense industry, nuclear power plants, water utilities, oil and gas supply firms, non-profit organizations and federal agencies. And in case any of the firms from the specified industries get infected, then the BlackMatter Ransomware group is ready to decrypt their database for free."
