Title: Operation: ArmorPiercer hits Indian subcontinent
Description: Cisco Talos recently discovered a malicious campaign we’re calling “Operation: ArmorPiercer” targeting government employees and military personnel in the Indian subcontinent with two commercial and commodity RAT families known as NetwireRAT (aka NetwireRC) and WarzoneRAT (aka Ave Maria). The attackers delivered a variety of lures to their targets, predominantly posing as guides related to Indian governmental infrastructure and operations such as Kavach and I.T.-related guides in the form of malicious Microsoft Office documents and archives (RARs, ZIPs) containing loaders for the RATs. This campaign illustrates another instance of a highly motivated threat actor using a set of commercial and commodity RAT families to infect their victims. These RATs are packed with many features out-of-the-box to achieve comprehensive control over the infected systems. It is also highly likely that these malware families establish footholds into the victim's networks to deploy additional plugins and modules.
