The increasing demand for domain-specific and human-aligned Large Language Models (LLMs) has led to the widespread adoption of Supervised Fine-Tuning (SFT) techniques. SFT datasets often comprise valuable instruction-response pairs, making them highly valuable targets for potential extraction. This paper studies this critical research problem for the first time. We start by formally defining and formulating the problem, then explore various attack goals, types, and variants based on the unique properties of SFT data in real-world scenarios. Based on our analysis of extraction behaviors of direct extraction, we develop a novel extraction method specifically designed for SFT models, called Differentiated Data Extraction (DDE), which exploits the confidence levels of fine-tuned models and their behavioral differences from pre-trained base models. Through extensive experiments across multiple domains and scenarios, we demonstrate the feasibility of SFT data extraction using DDE. Our results show that DDE consistently outperforms existing extraction baselines in all attack settings. To counter this new attack, we propose a defense mechanism that mitigates DDE attacks with minimal impact on model performance. Overall, our research reveals hidden data leak risks in fine-tuned LLMs and provides insights for developing more secure models.

The rapid advancement of generative models has led to the synthesis of real-fake ambiguous voices. To erase the ambiguity, embedding watermarks into the frequency-domain features of synthesized voices has become a common routine. However, the robustness achieved by choosing the frequency domain often comes at the expense of fine-grained voice features, leading to a loss of fidelity. Maximizing the comprehensive learning of time-domain features to enhance fidelity while maintaining robustness, we pioneer a \textbf{\underline{t}}emporal-aware \textbf{\underline{r}}ob\textbf{\underline{u}}st wat\textbf{\underline{e}}rmarking (\emph{True}) method for protecting the speech and singing voice. For this purpose, the integrated content-driven encoder is designed for watermarked waveform reconstruction, which is structurally lightweight. Additionally, the temporal-aware gated convolutional network is meticulously designed to bit-wise recover the watermark. Comprehensive experiments and comparisons with existing state-of-the-art methods have demonstrated the superior fidelity and vigorous robustness of the proposed \textit{True} achieving an average PESQ score of 4.63.

AI firm DeepSeek is aiding China's military and intelligence operations, a senior U.S. official said, adding that the Chinese tech startup sought to use Southeast Asian shell companies to access high-end semiconductors that cannot be shipped to China under U.S. rules. The U.S. conclusions reflect a growing conviction in Washington that the capabilities behind the rapid rise of one of China's flagship AI enterprises may have been exaggerated and relied heavily on U.S. technology. Hangzhou-based DeepSeek sent shockwaves through the technology world in January, saying its artificial intelligence reasoning models were on par with or better than U.S. industry-leading models at a fraction of the cost.

YouTube should be included in the ban on under-16s accessing social media, the nation's online safety chief has said as she urges the Albanese government to rethink its decision to carve out the video sharing platform from new rules which apply to apps such as TikTok, Snapchat and Instagram. The eSafety commissioner, Julie Inman Grant, also recommended the government update its under-16s social media ban to specifically address features such as stories, streaks and AI chatbots which can disproportionately pose risk to young people. The under-16s ban will come into effect in December 2025, despite questions over how designated online platforms would verify users' ages, and the government's own age assurance trial reporting last week that current technology is not "guaranteed to be effective" and face-scanning tools have given incorrect results. Although then communications minister Michelle Rowland initially indicated YouTube would be part of the ban legislated in December 2024, the regulations specifically exempted the Google-owned video site. Guardian Australia revealed YouTube's global chief executive personally lobbied Rowland for an exemption shortly before she announced the carve out.

Over the past decade, quantum computing has grown into a billion-dollar industry. Everyone seems to be investing in it, from tech giants, such as IBM and Google, to the US military. But Ignacio Cirac at the Max Planck Institute of Quantum Optics in Germany, a pioneer of the technology, has a more sober assessment. "A quantum computer is something that at the moment does not exist," he says. That is because building one that actually works – and is practical to use – is incredibly difficult.

Kyiv, Ukraine – There is a Persian word millions of Ukrainians fear. Shahed – also spelled as Shaheed or Shahid, originally a Quranic term for "martyr" or "witness" – is the name given to the triangular, explosives-laden, Iranian-designed drones that became a harrowing part of daily life and death in wartime Ukraine. These days, they are assembled in the Volga-region Russian city of Yelabuga and undergo constant modifications to make them faster, smarter and deadlier during each air raid that involves hundreds of drones. Their latest Russian versions shot down in Ukraine earlier this month have artificial intelligence modules to better recognise targets, video cameras and two-way radio communication with human operators. "The word'Shahed' will forever be cursed in Ukrainian next to'Moscow' and'Putin'," said Denys Kovalenko, referring to Russian President Vladimir Putin. Kovalenko's face and arms were cut by glass shards after a Shahed exploded above his northern Kyiv neighbourhood in 2023.

Utah Attorney General Sean Reyes speaks at the Utah State Capitol in Salt Lake City, last year after state leaders announced they are suing the federal government over 18.5 million acres of Bureau of Land Management land, which covers about 34% of Utah.Saige Miller / KUER via High Country News This story was originally published by High Country News and Public Domain and is reproduced here as part of the Climate Desk collaboration. Last year, as Utah prepared to file a federal lawsuit aiming to take control of millions of acres of federal public land within its borders, state officials sought help swaying public opinion in their favor. So they turned to a group of public relations professionals at Penna Powers, a media and branding firm based in Salt Lake City. Backed with a commitment of more than two million in taxpayer funds, the firm sprang into action. One of the early orders of business was studying the opposition. In June 2024, an assistant attorney general sent an email to numerous state government colleagues and Penna Powers staffers that contained a video from the Theodore Roosevelt Conservation Partnership (TRCP) in which the well-known hunter and media personality Randy Newberg described the dangers of transferring federal land to state control.

In the span of just a few years, drones have become instrumental in warfare. Conflicts in Ukraine, Iran, Nagorno-Karabakh, Sudan, and elsewhere have shown how autonomous vehicles have become a quintessential part of modern combat. It's a fact that Taiwan knows all too well. The island nation, fearing imminent invasion from China, has both the need, know-how, and industry necessary to build a robust and advanced drone program. Yet Taiwan, which has set an ambitious target of producing 180,000 drones per year by 2028, is struggling to create this industry from scratch.

Zubaida starts her day at eight in the morning, sorting discarded plastics, glass, and chemicals with her bare hands, to collect items she can sell. With waste-segregation centers in this part of East Delhi currently shut down, she and other waste-pickers from the Seemapuri slum work outside by a dusty road through the hottest hours of the day, under the blazing sun. There is no fan or shade. With Delhi's heat wave season here, they are constantly exposed to intense high temperatures. On June 11, the India Meteorological Department (IMD) issued a red alert for Delhi, warning of a high risk of heat illness and heat stroke.

A "massive" Russian drone and missile attack has killed at least six people in Ukraine's capital and the surrounding region, according to Ukrainian officials. Officials said the strikes on Monday morning targeted residential areas in numerous districts across Kyiv. The assault on the city, the second huge overnight blitz in a week, suggests Russia is eager to raise the pressure as global attention is dominated by the United States's decision to join Israel's escalating air campaign against Iran. Possibly, several waves of enemy drones," Tymur Tkachenko, head of Kyiv's military administration, said in a statement. "The Russians' style is unchanged – to hit where there may be people," Tkachenko said on Telegram. "Residential buildings, exits from shelters – this is the Russian style.
