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.

Ring adopts new TAKE encryption standard for smart home devices

SCM feed for Latest

Ring has adopted a new encryption standard called TAKE for its smart home devices. This standard uses a rotating set of encryption keys that are temporarily stored in the cloud, allowing Ring to secure active user features. The implementation of TAKE is designed to enhance the security of user data and improve the overall safety of smart home devices. While this development aims to bolster encryption practices, it raises questions about the security of cloud-stored keys and how they are managed. Users of Ring devices should stay informed about these changes to understand how their data is protected and what potential vulnerabilities may exist in the cloud storage approach.

Carhartt data breach claims inflated by synthetic data, analysis finds

SCM feed for Latest

On August 13, the hacking group ShinyHunters claimed to have leaked 50GB of data from Carhartt after demanding a ransom of $3.3 million. However, recent analysis suggests that the data leak may not be as significant as initially reported, with claims of inflated figures due to synthetic data. This incident raises concerns about the reliability of data breaches reported by cybercriminals and highlights the risks companies face from extortion attempts. If the data claims are exaggerated, it could lead to unnecessary panic among Carhartt's customers and stakeholders, as well as impact the company's reputation. It's crucial for organizations to remain vigilant and verify claims made by hackers to protect their interests.
