GoCaracal Malware Uses Ethereum Smart Contract to Fetch Replacement C2 Address

The Hacker News

In June 2026, a new malware framework named GoCaracal was identified during an intrusion at a communications organization in Venezuela. Linked to the Dark Caracal group, this Go-based malware allows attackers to gain remote shell access and execute malicious payloads. It also has capabilities for stealing browser data, logging keystrokes, and controlling remote desktops. The use of Ethereum smart contracts to dynamically fetch replacement command-and-control (C2) addresses makes it particularly sophisticated and harder to track. This incident is concerning as it highlights the evolving tactics of cybercriminals and the potential risks to sensitive information within the communications sector.
