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.

PhantomEnigma is a cybercriminal group that has been using compromised Brazilian government websites and legitimate email channels to distribute malware. Their primary targets are financial institutions, particularly banks, which they aim to infiltrate while avoiding detection by security systems. This method of attack allows them to maintain persistent access to their victims' networks. The use of trusted government sites adds a layer of credibility that makes it easier for them to trick users into downloading malicious software. As these tactics evolve, organizations need to be vigilant about the security of their online interactions and the integrity of the websites they visit.
The FBI has expressed concerns regarding Anthropic's AI model, Mythos, viewing it as a potential challenge for law enforcement. As AI technologies advance, the FBI is worried that such systems could be exploited for malicious purposes, complicating their ability to investigate crimes and maintain public safety. This concern reflects a broader trend where law enforcement agencies are grappling with the implications of rapidly evolving AI tools in the hands of bad actors. The FBI's stance signals the need for more dialogue about how to balance innovation in AI with the necessary safeguards to protect society. This situation emphasizes the importance of proactive measures in developing AI technologies to prevent misuse.
Recent reports have revealed that certain smart TV apps from LG and Samsung may be unintentionally acting as proxies, relaying other users' internet traffic. This situation raises significant privacy concerns for those who use these devices, as their personal data could be exposed without their consent. LG has announced plans to suspend the rogue apps involved, while Samsung has also acknowledged the issue and is assessing its impact. Users are encouraged to check their devices for affected apps and take necessary precautions to protect their privacy. This incident serves as a reminder of the potential vulnerabilities in smart devices that many people may overlook.
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.
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.
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.
