In September 2016, we noticed that operators of the updated CRYSIS ransomware family (detected as RANSOM_CRYSIS) were targeting Australia and New Zealand businesses via remote desktop (RDP) brute force attacks. Since then, brute force RDP attacks are still ongoing, with both SMEs and large enterprises across the globe affected. In fact, the volume of these attacks doubled in January 2017 from a comparable period in late 2016. While a wide variety of sectors have been affected, the most consistent target has been the healthcare sector in the United States.
