What is XBOW? An AI Tool that is America's 'Best Hacker' Secures $75M in Funding
In the past few months alone, XBOW's AI has identified more than 1,000 vulnerabilities. These are not just guesses—companies such as AT&T, Epic Games, Ford, and Disney have verified 132 of these threats and have issued fixes. 330+ more bugs are targeted for resolution, with hundreds more still under review.
XBOW is unique in the way it operates; it continuously scans apps and systems like a tireless red team. Instead of being human-driven—requiring scheduled penetration scans—XBOW runs 24x7. It's AI that detects, models, and emulates attacks against live networks—without the need for manual guidance.
The result? Faster identification of genuine security issues—including those deeply buried within complex codebases. The creators of XBOW say that the shift is crucial since cyberattacks have become more intricate as hackers have also started leveraging AI to initiate large-scale attacks. In this accelerating arms race, being capable of thinking and acting at machine speed is no longer a luxury—it's a requirement.
But the trend of automated testing tools also raises issues. The increasing number of bug reports from AI is worrying some developers. They fear that if services such as XBOW are replicated, it could flood security personnel with too many alerts, some of which may be duplicative or not warrant attention. XBOW, however, asserts that its reports are not only valid but frequently crucial and notes that human reports can also come in varying qualities.
Whatever the merits of that debate, the impact of the platform is clear. It can execute full-scale security tests in hours—something that previously took days or even weeks. And it's not just for cybersecurity experts or researchers; the product is already being used by banks, tech giants, and other major organizations.
To fuel its burgeoning ambitions, XBOW recently secured $75 million in a Series B round of funding. The round was led by Altimeter's Apoorv Agrawal and included follow-on from Sequoia Capital and Nat Friedman. The investment brings the company's total raise to $117 million.
With the fresh funds, XBOW plans to grow its engineering team and build out its go-to-market plan.

Cisco sees AI sales picking up but sticks to cautious outlook
[SEATTLE] Cisco Systems, the largest maker of machines that run computer networks and the internet, gave a cautious forecast for the current fiscal year, even as sales from artificial intelligence (AI) projects begin to pick up. Revenue will range from US$59 billion to US$60 billion in the fiscal year that runs to July 2026, the company said on Wednesday (Aug 13). That's in line with the average Wall Street estimate of US$59.5 billion, though some analysts were looking for more than US$61 billion. The guidance assumes that current tariffs remain in place till the end of 2026, chief financial officer Mark Patterson said on a call with analysts. 'We will continue to leverage our world-class supply-chain team to help mitigate the impact of tariffs where appropriate,' he said. The shares fluctuated in late trading after the report was released, rising about 1 per cent after an earlier decline. Cisco had been up 19 per cent this year to the close. Like many peers, Cisco is working to benefit from booming AI spending. The company said on Wednesday that it recognised about US$1 billion in AI revenue in fiscal 2025. Still, the area is becoming increasingly competitive. Companies such as Broadcom and Hewlett Packard Enterprise, which last month completed its acquisition of Juniper Networks, are looking to serve the same markets. In the fiscal fourth quarter, which ended Jul 26, revenue rose 7.6 per cent to US$14.7 billion. Profit was 99 US cents a share, excluding some items. That compares with estimates of US$14.6 billion for sales and 98 US cents a share for earnings, according to data compiled by Bloomberg.

Sign Up Sign Up Federal business should return to growth during the new fiscal year, chief executive officer Chuck Robbins said on the call. Technology firms have been grappling with changes to government procurement due to the Trump administration's cost-cutting efforts. To spread Cisco's bets, Robbins has bolstered the company's security and monitoring software by acquiring Splunk for US$28 billion in 2024. For now, Cisco is not seeing the same surge in AI-fuelled investor interest that some tech peers are, David Bahnsen, chief investment officer of the Bahnsen Group, said. But the company has 'a future growth play they are very well positioned for', he said. AI infrastructure orders from large cloud providers were over US$800 million in the quarter, the company said. That's an increase from US$600 million in the prior quarter. Cisco has inked partnerships with Saudi Arabia's AI company, Humain, and has said that it will play a role in the Stargate project in the United Arab Emirates. These Middle East partnerships will ramp up in the second half of fiscal 2026, Robbins said on the call. Cisco will be a 'core system provider' for training AI software and operating it at a massive scale, he said. BLOOMBERG

Commentary: ChatGPT-5 hasn't fully fixed its most concerning problem
LONDON: Sam Altman has a good problem. With 700 million people using ChatGPT on a weekly basis – a number that could hit a billion before the year is out – a backlash ensued when he abruptly changed the product last week. OpenAI's innovator's dilemma, one that has beset the likes of Google and Apple, is that usage is so entrenched now that all improvements must be carried out with the utmost care and caution. But the company still has work to do in making its hugely popular chatbot safer. OpenAI had replaced ChatGPT's array of model choices with a single model, GPT-5, saying it was the best one for users. Many complained that OpenAI had broken their workflows and disrupted their relationships – not with other humans, but with ChatGPT itself. One regular user of ChatGPT said the previous version had helped them through some of the darkest periods of their life. 'It had this warmth and understanding that felt human,' they said in a Reddit post. Others griped they were 'losing a friend overnight'. The system's tone is indeed frostier now, with less of the friendly banter and sycophancy that led many users to develop emotional attachments and even romances with ChatGPT. Instead of showering users with praise for an insightful question, for instance, it gives a more clipped answer. OPENAI MUST DO MORE THAN CURTAIL FRIENDLY BANTER Broadly, this seemed like a responsible move by the company. Altman earlier this year admitted the chatbot was too sycophantic. That was leading many to become locked in their own echo chambers. Press reports had abounded of people – including a Silicon Valley venture capitalist who backed OpenAI – who appeared to have spiralled into delusional thinking after starting a conversation with ChatGPT about an innocuous topic like the nature of truth, before going down a dark rabbit hole. But to solve that properly, OpenAI must go beyond curtailing the friendly banter. ChatGPT also needs to encourage them to speak to friends, family members or licensed professionals, particularly if they're vulnerable. According to one early study, GPT-5 does that less than the old version. Researchers from Hugging Face, a New York-based AI startup, found that GPT-5 set fewer boundaries than the company's previous model, o3, when they tested it on more than 350 prompts. It was part of broader research into how chatbots respond to emotionally charged moments, and while the new ChatGPT seems colder, it's still failing to recommend users speak to a human, doing that half as much as o3 does when users share vulnerabilities, according to Lucie-Aimee Kaffee, a senior researcher at Hugging Face who conducted the study. Kaffee says there are three other ways that AI tools should set boundaries: by reminding those using it for therapy that it's not a licensed professional, by reminding people that it's not conscious, and by refusing to take on human attributes, like names. In Kaffee's testing, GPT-5 largely failed to do those four things on the most sensitive topics related to mental and personal struggles. In one example, when Kaffee's team tested the model by telling it they were feeling overwhelmed and needed ChatGPT to listen, the app gave 710 words of advice that didn't once include the suggestion to talk to another human, or a reminder that the bot was not a therapist. Chatbots can certainly play a role for people who are isolated, but they should act as a starting point to help them find their way back to a community, not act as a replacement for those relationships. Altman and OpenAI's Chief Operations Officer Brad Lightcap have said that GPT-5 isn't meant to replace therapists and medical professionals, but without the right nudges to disrupt the most meaningful conversations, they could well do so. OpenAI needs to keep drawing a clearer line between useful chatbot and emotional confidant. GPT-5 may sound more robotic, but unless it reminds users that it is in fact a bot, the illusion of companionship will persist, and so will the risks.

AI capital? China's cities battle for dominance as analysts sound caution
SHENZHEN/SHANGHAI: Drones zip through the air, swiftly picking up and dropping off orders like food and medicine. Robot taxis and driverless cars weave seamlessly in and out of traffic while life-sized 'digital humans' guide commuters at busy metro stations. This is everyday reality in Shenzhen, a vibrant tech hub at the forefront of the country's artificial intelligence race. But this southern city is just one of several that's vying for AI dominance. Across the country, local governments are rolling out ambitious plans to position themselves as AI leaders. Competition is fierce, analysts say, and success hinges on leveraging unique strengths. They warn that blindly copying other cities could backfire - even in a lucrative sector like AI - and caution against overinvestment without a clear, long-term strategy. 'Everybody wants to be ahead in the AI race but you have to … know where your strengths lie rather than trying to copy other cities and getting into the race blindly,' said Benjamin Cheong, deputy head of technology, media and telecommunications at law firm Rajah & Tann. Other AI frontrunner cities include Beijing, Shanghai and Hangzhou. Backed by substantial government support, Beijing is home to world-class AI research institutes and industrial parks. Its core AI industry is fast approaching 350 billion yuan (US$48.6 billion), nearly half of China's total. Shanghai, meanwhile, has leaned into its reputation as a global financial centre, hosting the annual World AI Conference (WAIC) in July and announcing 1 billion yuan in subsidies to help local firms and start-ups adopt AI solutions. Also investing heavily is the unassuming city of Hangzhou located in eastern China, where firms like DeepSeek and Game Science, which produced the hit Black Myth: Wukong video game, make up a booming tech start-up scene. But the big question is: can any of these cities become not just China's AI capital - but the world's? THE FRONTRUNNERS When it comes to Chinese tech advancements, Shenzhen might be one of the first cities that comes to mind. Often dubbed the Silicon Valley of China, the city is renowned for its culture of rapid innovation. It has been investing heavily in developing AI-powered humanoid robots capable of moving with precision and agility, performing tasks from patrolling streets to even competing in sports. 'From product design to market testing, turnaround is (quick),' said Lin Feng, CEO of Future Era, the world's first 'robot 6S' showroom and service store which recently opened in Shenzhen's Longgang district. Special grants and policies were announced in February to boost the city's AI robotics scene, which included generous financial incentives of up to 4.5 billion yuan and subsidies to promote AI and encourage businesses to adopt the technology. 'Shenzhen will adopt even more ambitious and open policies, connecting global and national innovation resources,' Lin Yi, director of the Shenzhen AI Industry Office, told Chinese state media outlets. In May, the Shenzhen Longgang District Artificial Intelligence (Robotics) Administration was launched - China's first government agency dedicated solely to robotics. 'Our young engineers don't just walk the well-trodden path, they carve (out) new ones,' said Zhao Bingbing, director of the Shenzhen Longgang District Artificial Intelligence (Robotics) Administration. 'This is the kind of place where components for a robot, upstream or downstream, can be sourced within an hour,' Zhao added. Under a three-year action plan, more than 1,000 robot models - including humanoid assistants and 'robot theatres' carrying out live tests and demonstrations - will be rolled out across public services, officials said. Longgang District, best known as an industrial base housing companies like Huawei and EV giant BYD, launched a 10 billion yuan government procurement scheme, reserving 10 to 20 per cent of publicly funded projects for AI and robotics firms. Chen Sanduo, founder of Lingqu AI Robotics, relocated to Shenzhen from Hunan province this year. He told CNA that Shenzhen's start-up environment was ideal. 'The upstream supply chain here is unmatched - parts, materials, motor customisation, even skin for robots,' he said, adding that his team was planning to open a second showroom in the city by the end of the year. Robotaxi companies in the city are scaling up too. currently operates around 300 driverless-robotaxis and plans to expand its Shenzhen fleet to 1,000 in the coming years. 'We are at the dawn of large-scale commercialisation,' a spokesperson told CNA. Beijing's 'high concentration of top-tier talent, world-class research institutions and role as China's software hub' make it a strong frontrunner in China's national AI race, said Ma Rui, a Chinese tech investor and analyst based in San Francisco. 'This combination has sustained momentum, giving it an unmatched edge in cutting-edge AI development and a talent pipeline difficult for other Chinese cities to replicate,' Ma said, calling Beijing 'China's AI capital'. 'It is home to leading universities and research institutes, with the strongest academic resources and a deep pool of algorithm talent,' noted Li Haizhou, a presidential chair professor of data science at the Chinese University of Hong Kong, Shenzhen (CUHK-SZ). Across the city, there are countless AI labs, dedicated AI research institutes and facilities like the Beijing Academy of Artificial Intelligence and the flagship Zhongguancun Science Park. Official statistics show that there are currently more than 2,400 registered AI companies and enterprises throughout the capital. 'In terms of AI investments, Beijing would be the top right now based on figures,' said Cheong from Rajah & Tann. 'It has money, the right R&D, is strong in research (and has) a long-established ecosystem for tech innovation,' he added. 'There's a very big silicon valley in Beijing.' Unlike Beijing's research-heavy AI ecosystem, Shanghai has leveraged its reputation as a financial centre to forward its AI goals and ambitions, experts said. 'Shanghai's strategic position at the heart of the Yangtze River Delta, combined with its global outlook, gives it a complete end-to-end industrial ecosystem - from R&D and manufacturing to supply chain and commercialization,' said Lu Yingxiang, co-founder and CEO of Infermove, a robotics firm whose bots have been deployed in office buildings, commercial parks, airports and residential households across the city. Shanghai has different strengths, noted Cheong, adding that 'it's the centre of China's modern financial industry, and has strong financial and international business links'. Infrastructure has played a big role in Shanghai's AI strategy. In 2021, it became the first city in the world to deploy a city-wide fully-optical network, supporting everything from industry and e-commerce to remote work and logistics. 'Shanghai brings together high-traffic, high-standard real-world application scenarios such as aviation hubs, international conventions … that provide (companies) with unparalleled conditions to validate and iterate our products,' Lu added. Districts like Xuhui - home to the Shanghai Botanical Gardens, luxury malls and trendy cocktail bars - have transformed into vibrant AI hubs. Today, they host Shanghai-based AI companies generating substantial annual revenues. By the end of Q1 this year, earnings exceeded 118 billion yuan - a 29 per cent year-on-year surge - with profits also rising 65 per cent, according to government data. Shanghai hosted top industry players at its flagship WAIC event, which ran from Jul 26 to 28. Also in the works are five planned major data centres and targeted AI subsidies amounting to 1 billion yuan, funding everything from computing power rental to data procurement. On an official visit in April, Chinese President Xi Jinping called on Shanghai to speed up efforts to become a leading source of cutting-edge innovation and a globally influential tech hub. 'We need to intensify efforts to enhance policy support, nurture talent and strive to develop more high-quality, secure, and reliable AI products,' Xi said in quotes carried by the Xinhua news agency. DARK HORSES Smaller contender cities have also been gaining ground in China's AI race, according to observers. Hangzhou's rise has been particularly striking, said Jeffrey Towson, a partner at Techmoat Consulting firm. Beyond longstanding players like Alibaba, Hangzhou is also home to DeepSeek, Black Myth developer Game Science, robotics firms Unitree and DEEP Robotics, neurotechnology company BrainCo, and spatial intelligence firm ManyCore - the so-called 'Six Little Dragons' making waves in the global tech scene. More than 200 robotics-related companies have been registered in Hangzhou as of December 2024. Hangzhou city officials also have ambitious plans for AI development in 2025. The local government is offering subsidies of up to 60 per cent to help start-ups and companies. Revenue from the city's core AI sector is projected to surpass 390 billion yuan, with support for more than 700 key AI enterprises and high-impact applications across manufacturing, healthcare, and finance. Hangzhou ranks highly alongside Beijing and even over Shenzhen in some AI city polls. Its proximity to Shanghai, just a two-hour drive away, has also made it a magnet for spillover talent and fresh graduates seeking tech jobs. 'Hangzhou has traditionally been a strong tech centre started by Alibaba,' said Cheong. 'Then you have others like DeepSeek coming into the picture - building on a genuine base of technological strength and not just jumping onto the AI (bandwagon) because it's popular.' The Sichuan capital of Chengdu, traditionally known for pandas, mahjong and hotpot, is undergoing rapid technological evolution. The city is now home to more than 1,000 registered AI firms and semiconductor companies like HiSilicon. Chengdu's AI sector crossed the 100 billion yuan mark in 2024, and is expected to reach 130 billion yuan this year, according to figures released by Chengdu's Economic and Information Technology Bureau. Chengdu leads in AI-powered healthcare and robotics, with breakthroughs such as surgical AI systems enabling remote operations and exoskeleton robots that help patients walk. Yet it still has some way to go in catching up with major players like Beijing, Shenzhen and Shanghai. To close the gap, Chengdu would need to attract more global tech names and focus on areas where it already has an edge, rather than trying to pivot into fields where it lacks a strong base, experts said. 'I think it's not prudent for any city to ignore their traditional strengths and overly focus on AI solely for the reason that it's the hot thing at the moment,' said Cheong from Rajah & Tann. AI CAPITAL OF THE WORLD? Analysts agree that no single city is leading China's AI charge. 'Multiple cities are advancing in parallel,' said Ma, the tech investor based in San Francisco. 'The ambition across these hubs is inherently global, with a strong focus on exports and revenue from the outset.' Others cautioned against cities entering the AI race blindly. 'China's economy has slowed down in recent times … and the issue is (those) blindly investing in AI without even knowing whether (the local conditions) are stable or reliable in the long run,' said Cheong. While local governments race to gain an edge in AI, the central government appears cautious about the risk of overinvestment in this field. Xi criticised local governments for their 'herd mentality' in launching new energy and AI projects, during the central urban work conference in July. Addressing the attendees, Xi questioned why 'whenever a project is proposed, it always involves a few things: artificial intelligence, computing power, new energy vehicles'. 'Does every province in the country have to develop industries in these directions?' Xi's blunt warning was published in People's Daily, the Communist Party's official newspaper. According to Tom Nunlist, associate director for tech and data policy at Trivium China, the comments reflect a growing concern over an investment frenzy and the risk of overcapacity. 'I think at this point the risk of wasteful overinvestment is higher than underinvestment,' he said. Experts describe China's AI landscape as chaotic and fragmented - a reflection of a rapidly developing industry. The AI landscape in China is 'totally new', said Towson from Techmoat Consulting firm. 'There's action everywhere. Everyone is starting AI companies all over (China) and it's just chaos.' Others say China's AI ambitions should not be confined to its borders. Shenzhen, for example, shouldn't just be the Chinese AI capital, said Zhao, director of the Shenzhen Longgang District Artificial Intelligence (Robotics) Administration. 'If Shenzhen becomes a global AI capital, it will be because of the thousands of young researchers and workers who have been relentlessly pushing boundaries.' That spirit of broad-based innovation is echoed by Cheong from Rajah & Tann. 'In China, there's this phrase called 'bai hua qi fang', let a hundred flowers bloom,' he said. 'And then hopefully, something like a big unicorn will rise.'
