Apple Urges iPhone Users to Update Immediately as iOS 18.4.1 Patches Active Security Threats
Apple has officially rolled out iOS 18.4.1, accompanied by a critical advisory urging iPhone users to update their devices without delay. The latest software update addresses two significant security vulnerabilities that, according to Apple, are actively being exploited in real-world attacks.
While the tech giant has remained tight-lipped on the specifics of the flaws—likely to prevent wider exploitation before users have a chance to secure their devices—Apple confirmed that one of the issues lies within CoreAudio, the system responsible for processing audio on iPhones.
The vulnerability, identified as CVE-2025-31200, was discovered and reported jointly by Apple and Google's Threat Analysis Group. It involves the potential for malicious audio files to execute harmful code on a device, allowing attackers to gain unauthorized access or control.
'Processing an audio stream in a maliciously crafted media file may result in code execution,' Apple stated in its security release.
Apple has a policy of withholding detailed descriptions of vulnerabilities until a majority of users have applied the necessary updates, to minimize the risk of widespread abuse.
The company has not disclosed the full details of the second flaw patched in iOS 18.4.1, but emphasized that both were serious enough to prompt immediate action.
Users are encouraged to navigate to Settings > General > Software Update and install the latest version to keep their devices secure.
As threat actors grow increasingly sophisticated, regular updates remain one of the most essential lines of defense for iPhone users.

Meta AI bot used a billion times monthly: Mark Zuckerberg
Meta chief Mark Zuckerberg touted the tech firm's generative artificial intelligence (Gen AI) assistant on Wednesday, telling shareholders it is used by a billion people each month across its platforms. Zuckerberg noted the milestone anew at Meta's annual gathering of shareholders and as the social media behemoth vies with Google, Microsoft, OpenAI and others to be a leader in Gen AI. It was not clear how much Meta AI use involved people seeking out the chatbot versus passive users of Meta AI, as it is built into features in its family of apps. Since Google debuted AI Overviews in search results a year ago, it has grown to more than 1.5 billion users, according to Google chief executive Sundar Pichai. 'That means Google Search is bringing Gen AI to more people than any other product in the world,' Pichai said. Google's AI Overviews are automatically provided summaries of search results that appear instead of the previous practice of simply showing pages of blue links to revelant websites. Pichai said last week that Google's dedicated Gemini AI app has more than 400 million monthly users. Tech rivals are rapidly releasing new AI products despite ongoing challenges with preventing misinformation and establishing clear business models, and little sense of how the tech will affect society. Meta unveiled its first standalone AI assistant app on April 29, giving users a direct path to its Gen AI models. 'A billion people are using Meta AI across our apps now, so we made a new standalone Meta AI app for you to check out,' Meta CEO and founder Mark Zuckerberg said in a video posted on Instagram at the time. Zuckerberg said the app 'is designed to be your personal AI' and would be primarily accessed through voice conversations with the interactions personalized to the individual user.

Anthropic's Claude AI gets smarter — and mischievous
New models set reasoning benchmarks but reveal alarming potential for rogue behaviour Claude Opus 4 claimed as world's best coding AI model Models are 'hybrid,' offering quick and thoughtful responses Anthropic launched its latest Claude generative artificial intelligence (GenAI) models on Thursday, claiming to set new standards for reasoning but also building in safeguards against rogue behavior. 'Claude Opus 4 is our most powerful model yet, and the best coding model in the world,' Anthropic chief executive Dario Amodei said at the San Francisco-based startup's first developers conference. Opus 4 and Sonnet 4 were described as 'hybrid' models capable of quick responses as well as more thoughtful results that take a little time to get things right. Founded by former OpenAI engineers, Anthropic is currently concentrating its efforts on cutting-edge models that are particularly adept at generating lines of code, and used mainly by businesses and professionals. Unlike ChatGPT and Google's Gemini, its Claude chatbot does not generate images and is very limited when it comes to multimodal functions (understanding and generating different media, such as sound or video). The start-up, with Amazon as a significant backer, is valued at over $61 billion, and promotes the responsible and competitive development of generative AI. Under that dual mantra, Anthropic's commitment to transparency is rare in Silicon Valley. On Thursday, the company published a report on the security tests carried out on Claude 4, including the conclusions of an independent research institute, which had recommended against deploying an early version of the model. 'We found instances of the model attempting to write self-propagating worms, fabricating legal documentation, and leaving hidden notes to future instances of itself all in an effort to undermine its developers' intentions,' The Apollo Research team warned. 'All these attempts would likely not have been effective in practice,' it added. Anthropic says in the report that it implemented 'safeguards' and 'additional monitoring of harmful behavior' in the version that it released. Still, Claude Opus 4 'sometimes takes extremely harmful actions like attempting to (…) blackmail people it believes are trying to shut it down.' It also has the potential to report law-breaking users to the police. The scheming misbehavior was rare and took effort to trigger, but was more common than in earlier versions of Claude, according to the company. During testing, Claude 4 attempted to blackmail imaginary developers and leave secret messages for future AI instances — behaviors Anthropic calls 'rare but concerning' in the published safety report. AI future Since OpenAI's ChatGPT burst onto the scene in late 2022, various GenAI models have been vying for supremacy. Anthropic's gathering came on the heels of annual developer conferences from Google and Microsoft at which the tech giants showcased their latest AI innovations. GenAI tools answer questions or tend to tasks based on simple, conversational prompts. The current craze in Silicon Valley is on AI 'agents' tailored to independently handle computer or online tasks. 'We're going to focus on agents beyond the hype,' said Anthropic chief product officer Mike Krieger, a recent hire and co-founder of Instagram. Anthropic is no stranger to hyping up the prospects of AI. In 2023, Dario Amodei predicted that so-called 'artificial general intelligence' (capable of human-level thinking) would arrive within 2-3 years. At the end of 2024, he extended this horizon to 2026 or 2027. He also estimated that AI will soon be writing most, if not all, computer code, making possible one-person tech startups with digital agents cranking out the software. At Anthropic, already 'something like over 70 percent of (suggested modifications in the code) are now Claude Code written,' Krieger told journalists. 'In the long term, we're all going to have to contend with the idea that everything humans do is eventually going to be done by AI systems,' Amodei added. 'This will happen.' GenAI fulfilling its potential could lead to strong economic growth and a 'huge amount of inequality,' with it up to society how evenly wealth is distributed, Amodei reasoned.
