UNC1878 is a financially motivated threat actor that monetizes network access via the deployment of RYUK ransomware. Earlier this year, Mandiant published a blog on a fast-moving adversary deploying RYUK ransomware, UNC1878. Shortly after its release, there was a significant decrease in observed UNC1878 intrusions and RYUK activity overall almost completely vanishing over the summer. But beginning in early fall, Mandiant has seen a resurgence of RYUK along with TTP overlaps indicating that UNC1878 has returned from the grave and resumed their operations.
