Next.js Patches Critical AVIF and Windows Flaws Enabling Unauthenticated RCE

The Hacker News

Vercel has issued security patches for two serious vulnerabilities in the Next.js framework that could allow attackers to execute code remotely without authentication. The first vulnerability arises from the handling of AVIF image files, which can be manipulated to exploit the system. The second flaw is a path traversal issue that affects installations on Windows filesystems, enabling unauthorized access to files. These vulnerabilities are particularly concerning because they can be exploited without any user interaction, putting many applications at risk if they use Next.js. Developers using this framework should prioritize updating to the latest version to mitigate these risks.

Learn How to Build Security Operations Ready for AI-Powered Attacks

The Hacker News

Security teams are facing a new challenge as advanced AI technology is being used by attackers to exploit vulnerabilities more quickly than ever before. With AI, attackers can identify weaknesses in systems, generate code to exploit these vulnerabilities, and move through security defenses faster than traditional methods can detect. This shift means defenders have less time to respond to incidents, increasing the urgency for organizations to bolster their security operations. As attackers become more sophisticated, the need for improved detection and response strategies is critical for companies looking to protect their systems and data. This situation emphasizes the importance of adapting security measures to keep pace with evolving threats.

Spark RAT Targets Cambodia, Abuses Vulnerable OPSWAT Driver to Disable Security Tools

The Hacker News

A new campaign is targeting individuals and organizations in Cambodia using a remote access trojan (RAT) known as Spark RAT. The attackers are employing various lure themes, including government notices, public health information, and real estate content, to entice a wide range of potential victims. Notably, the campaign exploits a vulnerable OPSWAT driver, which allows the malware to disable security tools, making it easier for attackers to infiltrate systems undetected. This situation is concerning as it not only threatens personal and organizational data security but also raises alarms about the potential for broader impacts on national security and public safety. Users in Cambodia should be particularly vigilant and ensure their security measures are up to date.

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.
