Cybersecurity researchers have identified a sophisticated attack campaign targeting poorly managed Linux servers through SSH brute force attacks to deploy the SVF Botnet, a Python-based DDoS malware. This botnet leverages Discord for command-and-control and employs multiple proxy servers to amplify its attack capabilities. The malware transforms compromised systems into DDoS weapons, capable of launching Layer 7 HTTP floods and Layer 4 UDP floods. This attack highlights the persistent threat to inadequately secured Linux infrastructure with weak authentication mechanisms. The infection mechanism involves automated deployment via a single command execution, establishing a Python virtual environment and downloading the malware payload.
