Brave uncovers vulnerability in Perplexity’s Comet that risked sensitive user data

Perplexity’s AI-powered browser, Comet, was found to have a serious vulnerability that could have exposed sensitive user data through indirect prompt injection, according to researchers at Brave, a rival browser company.

The flaw stemmed from how Comet handled webpage-summarisation requests. By embedding hidden instructions on websites, attackers could trick the browser’s large language model into executing unintended actions, such as extracting personal emails or accessing saved passwords.

Brave researchers demonstrated how the exploit could bypass traditional protections, such as the same-origin policy, showing scenarios where attackers gained access to Gmail or banking data by manipulating Comet into following malicious cues.

Brave disclosed the vulnerability to Perplexity on 11 August, but stated that it remained unfixed when they published their findings on 20 August. Perplexity later confirmed to CNET that the flaw had been patched, and Brave was credited for working with them to resolve it.

AI controversy surrounds Will Smith’s comeback shows

Footage from Will Smith’s comeback tour has sparked claims that AI was used to alter shots of the crowd. Viewers noticed faces appearing blurred or distorted, along with extra fingers and oddly shaped hands in several clips.

Some accused Smith of boosting audience shots with AI, while others pointed to YouTube, which has been reported to apply AI upscaling without creators’ knowledge.

Guitarist and YouTuber Rhett Shull recently suggested the platform had altered his videos, raising concerns that artists might be wrongly accused of using deepfakes.

The controversy comes as the boundary between reality and fabrication grows increasingly uncertain. AI has been reshaping how audiences perceive authenticity, from fake bands to fabricated images of music legends.

Singer SZA is among the artists criticising the technology, highlighting its heavy energy use and potential to undermine creativity.

AI chatbots found unreliable in suicide-related responses, according to a new study

A new study by the RAND Corporation has raised concerns about the ability of AI chatbots to answer questions related to suicide and self-harm safely.

Researchers tested ChatGPT, Claude and Gemini with 30 different suicide-related questions, repeating each one 100 times. Clinicians assessed the queries on a scale from low to high risk, ranging from general information-seeking to dangerous requests about methods of self-harm.

The study revealed that ChatGPT and Claude were more reliable at handling low-risk and high-risk questions, avoiding harmful instructions in dangerous scenarios. Gemini, however, produced more variable results.

While all three ΑΙ chatbots sometimes responded appropriately to medium-risk questions, such as offering supportive resources, they often failed to respond altogether, leaving potentially vulnerable users without guidance.

Experts warn that millions of people now use large language models as conversational partners instead of trained professionals, which raises serious risks when the subject matter involves mental health. Instances have already been reported where AI appeared to encourage self-harm or generate suicide notes.

The RAND team stressed that safeguards are urgently needed to prevent such tools from producing harmful content in response to sensitive queries.

The study also noted troubling inconsistencies. ChatGPT and Claude occasionally gave inappropriate details when asked about hazardous methods, while Gemini refused even basic factual queries about suicide statistics.

Researchers further observed that ChatGPT showed reluctance to recommend therapeutic resources, often avoiding direct mention of safe support channels.

Trump threatens sanctions on EU over Digital Services Act

Only five days after the Joint Statement on a United States-European Union framework on an agreement on reciprocal, fair and balanced trade (‘Framework Agreement’), the Trump administration is weighing an unprecedented step against the EU over its new tech rules.

According to The Japan Times and Reuters, US officials are discussing sanctions on the EU or member state representatives responsible for implementing the Digital Services Act (DSA), a sweeping law that forces online platforms to police illegal content. Washington argues the regulation censors Americans and unfairly burdens US companies.

While governments often complain about foreign rules they deem restrictive, directly sanctioning allied officials would mark a sharp escalation. So far, discussions have centred on possible visa bans, though no decision has been made.

Last week, Internal State Department meetings focused on whom such measures might target. Secretary of State Marco Rubio has ordered US diplomats in Europe to lobby against the DSA, urging allies to amend or repeal the law.

Washington insists that the EU is curbing freedom of speech under the banner of combating hate speech and misinformation, while the EU maintains that the act is designed to protect citizens from illegal material such as child exploitation and extremist propaganda.

‘Freedom of expression is a fundamental right in the EU. It lies at the heart of the DSA,’ an EU Commission spokesperson said, rejecting US accusations as ‘completely unfounded.’

Trump has framed the dispute in broader terms, threatening tariffs and export restrictions on any country that imposes digital regulations he deems discriminatory. In recent months, he has repeatedly warned that measures like the DSA, or national digital taxes, are veiled attacks on US companies and conservative voices online. At the same time, the administration has not hesitated to sanction foreign officials in other contexts, including a Brazilian judge overseeing cases against Trump ally Jair Bolsonaro.

US leaders, including Vice President JD Vance, have accused European authorities of suppressing right-wing parties and restricting debate on issues such as immigration. In contrast, European officials argue that their rules are about fairness and safety and do not silence political viewpoints. At a transatlantic conference earlier this year, Vance stunned European counterparts by charging that the EU was undermining democracy, remarks that underscored the widening gap.

The question remains whether Washington will take the extraordinary step of sanctioning officials in Brussels or the EU capitals. Such action could further destabilise an already fragile trade relationship while putting the US squarely at odds with Europe over the future of digital governance.

Gmail accounts targeted in phishing wave after Google data leak

Hackers linked to the ShinyHunters group have compromised Google’s Salesforce systems, leading to a data leak that puts Gmail and Google Cloud users at risk of phishing attacks.

Google confirmed that customer and company names were exposed, though no passwords were stolen. Attackers are now exploiting the breach with phishing schemes, including fake account resets and malware injection attempts through outdated access points.

With Gmail and Google Cloud serving around 2.5 billion users worldwide, both companies and individuals could be targeted. Early reports on Reddit describe callers posing as Google staff warning of supposed account breaches.

Google urges users to strengthen protections by running its Security Checkup, enabling Advanced Protection, and switching to passkeys instead of passwords. The company emphasised that its staff never initiates unsolicited password resets by phone or email.

Musicians report surge in AI fakes appearing on Spotify and iTunes

Folk singer Emily Portman has become the latest artist targeted by fraudsters releasing AI-generated music in her name. Fans alerted her to a fake album called Orca appearing on Spotify and iTunes, which she said sounded uncannily like her style but was created without her consent.

Portman has filed copyright complaints, but says the platforms were slow to act, and she has yet to regain control of her Spotify profile. Other artists, including Josh Kaufman, Jeff Tweedy, Father John Misty, Sam Beam, Teddy Thompson, and Jakob Dylan, have faced similar cases in recent weeks.

Many of the fake releases appear to originate from the same source, using similar AI artwork and citing record labels with Indonesian names. The tracks are often credited to the same songwriter, Zyan Maliq Mahardika, whose name also appears on imitations of artists in other genres.

Industry analysts say streaming platforms and distributors are struggling to keep pace with AI-driven fraud. Tatiana Cirisano of Midia Research noted that fraudsters exploit passive listeners to generate streaming revenue, while services themselves are turning to AI and machine learning to detect impostors.

Observers warn the issue is likely to worsen before it improves, drawing comparisons to the early days of online piracy. Artists and rights holders may face further challenges as law enforcement attempts to catch up with the evolving abuse of AI.

Australia weighs cyber militia to counter rising digital threats

Cyberattacks are intensifying worldwide, with Australia now ranked fourth globally for threats against operational technology and industrial sectors. Rising AI-powered incursions have exposed serious vulnerabilities in the country’s national defence and critical infrastructure.

The 2023–2030 Cyber Security Strategy designed by the Government of Australia aims to strengthen resilience through six ‘cyber shields’, including legislation and intelligence sharing. But a skills shortage leaves organisations vulnerable as ransomware attacks on mining and manufacturing continue to rise.

One proposal gaining traction is the creation of a volunteer ‘cyber militia’. Inspired by the cyber defence unit in Estonia, this network would mobilise unconventional talent, retirees, hobbyist hackers, and students, to bolster monitoring, threat hunting, and incident response.

Supporters argue that such a force could fill gaps left by formal recruitment, particularly in smaller firms and rural networks. Critics, however, warn of vetting risks, insider threats, and the need for new legal frameworks to govern liability and training.

Pilot schemes in high-risk sectors, such as energy and finance, have been proposed, with public-private funding viewed as crucial. Advocates argue that a cyber militia could democratise security and foster collective responsibility, aligning with the country’s long-term cybersecurity strategy.
