U.S. cybersecurity and intelligence agencies on Tuesday disclosed that multiple nation-state hacking groups potentially targeted a "Defense Industrial Base Sector organization's enterprise network" as part of a cyber espionage campaign. " actors used an open-source toolkit called Impacket to gain their foothold within the environment and further compromise the network, and also used a custom data exfiltration tool, CovalentStealer, to steal the victim's sensitive data," the authorities said.

The U.S. Government today released an alert about state-backed hackers using a custom CovalentStealer malware and the Impacket framework to steal sensitive data from a U.S. organization in the Defense Industrial Base sector. The hackers combined custom malware called CovalentStealer, the open-source Impacket collection of Python classes, the HyperBro remote access trojan, and well over a dozen ChinaChopper webshell samples.
