This week introduced a new ransomware player that is targeting companies called RobbinHood. This ransomware recently took down the City of Greenville's computer systems and offers two different ransom payments; a price per computer or one for the entire network.

We also saw a new ransomware called NamPoHyu that is targeting remote Samba servers and encrypting their data remotely. Otherwise, it's mostly been new variants of older ransomware.
