Overall things have been steady over the past few days. We are still seeing EvilOSX and Drupal vulnerabilities being exploited. IN addition Necurs activity has increased and is significantly expanded. We have reported some suspicious CDN activity as well as some targeted malware infections that appear to be nation state activity.
Most of the Drupal based activity is cryptocurrency mining operations but there have been some targeted reports of direct attacks from North Korea using these same methods but they are a rarity. We are seeing Criminal Click Through activity as well and the usual scanning and automation attempts. It is apparent that SamSam is also active and being exploited in the healthcare sector.
