Stealthy Cyberattacks: Hackers Exploit Red Teaming Tools To Connect With C&C Servers

By Editor Last updated Mrz 4, 2025

Stealthy cyberattacks pose a significant threat in today’s digital landscape. Hackers are increasingly exploiting red teaming tools, such as PowerShell Empire, to connect with Command and Control (C&C) servers and carry out their malicious activities. PowerShell Empire is a widely-used post-exploitation red teaming tool, commonly employed in phishing campaigns, IT system exploitation, and watering hole attacks. The framework operates through a server and client architecture, wherein the client creates a listener and stager for the attack. The listener establishes a connection with the stager, which is then dropped and executed on the victim’s system, allowing the attacker to remotely manage compromised systems. Notably, the communication between the victim machine and the C&C server is encrypted and designed to blend with normal network activity, making detection challenging. To mitigate the risks associated with these stealthy cyberattacks, it is crucial to adopt protective measures such as downloading software from official app stores, utilizing reputable antivirus and internet security software, implementing strong passwords and multi-factor authentication, exercising caution when opening links from SMS or emails, regularly monitoring systems, applying updates, and adhering to cybersecurity best practices.
