Claude AI Just Cracked a Post-Quantum Test Scheme and Found a Faster 7-Round AES Attack

The Hacker News

Anthropic's Claude Mythos Preview has successfully developed a key-recovery attack against HAWK-256, a post-quantum signature scheme. This new attack utilizes a previously unexploited symmetry in the underlying lattice structure, potentially compromising the security of systems relying on HAWK-256. Additionally, the researchers reported a significant speed increase for an attack on seven-round AES-128, achieving a 200- to 800-fold performance boost, which could make this encryption easier to break. The implementation is designed to run on a powerful 96-core server, completing in roughly three hours and 42 minutes. This advancement poses a major concern for organizations using these cryptographic methods, as it could lead to faster and more efficient attacks on sensitive data.

Bugs in Hugging Face Diffusers Bypass Custom Code Safeguard

Infosecurity Magazine

Recent findings reveal that three vulnerabilities, identified as CVEs, in Hugging Face's diffusers library can allow malicious model repositories to execute code on any machine that loads them. This means that users who download and run models from compromised repositories could unwittingly expose their systems to harmful code. The implications are significant, especially for developers and researchers who rely on Hugging Face's tools for machine learning projects. It's crucial for users to be aware of these vulnerabilities to protect their environments and data. Researchers highlight the need for vigilance when sourcing machine learning models from public repositories.

AI-assisted security tools are finding more bugs, but the threat level has not changed

CyberScoop

A recent analysis by VulnCheck reveals that while AI-assisted security tools are identifying more software vulnerabilities, the rate at which these flaws are being exploited remains unchanged compared to traditional vulnerabilities. This suggests that despite advancements in technology, attackers are not necessarily faster at leveraging newly discovered bugs. The findings indicate that organizations using AI tools may not see an immediate reduction in risk, as the exploitation timelines for vulnerabilities have remained consistent. As companies continue to integrate AI into their security practices, it is crucial for them to maintain vigilance and not solely rely on automated tools to manage their cybersecurity posture.

Tengu Botnet Reboots Compromised Linux Devices When Defenders Kill Its Process

The Hacker News

A new botnet called Tengu, derived from the well-known Mirai botnet, has been identified targeting compromised Linux devices. Researchers from Nozomi Networks Labs found that Tengu can utilize a device's hardware watchdog feature to reboot itself whenever defenders attempt to terminate its main process. This persistence method allows Tengu to re-establish its operation even after being interrupted. The botnet primarily gains access through brute-force attacks on Telnet credentials. Tengu is capable of launching distributed denial-of-service (DDoS) attacks, which can overwhelm targeted systems and disrupt online services. This incident raises concerns for organizations relying on Linux devices, as Tengu's ability to persist poses a significant challenge for cybersecurity defenses.
