ProMediads Malvertising and Sundown-Pirate Exploit Kit Combo Drops Ransomware and Info Stealer

We’ve uncovered a new exploit kit in the wild through a malvertising campaign we’ve dubbed “ProMediads”. We call this new exploit kit Sundown-Pirate, as it’s indeed a bootleg of its precursors and actually named so by its back panel.
ProMediads has been active as early as 2016, employing Rig and Sundown exploit kits to deliver malware. Its activities dropped off in mid-February this year, but suddenly welled on June 16 via Rig. However, we noticed that ProMediads eschewed Rig in favor of Sundown-Pirate on June 25.
It’s worth noting that Sundown-Pirate is only employed by ProMediads so far. This could mean that it’s yet another private exploit kit, like the similarly styled GreenFlash Sundown exploit kit that was exclusively used by the ShadowGate campaign.
