  • Citigroup Mandates AI Training For 175,000 Employees To Help Them 'Reinvent Themselves'
    by msmash on 27/01/2026 at 9:25 pm

    Citigroup has rolled out mandatory AI training for all 175,000 of its employees across 80 locations worldwide, a sweeping initiative that CEO Jane Fraser describes as helping workers "reinvent themselves" before the technology permanently alters what they do for a living. The $205 billion bank sent out an internal memo last year requiring staffers to learn prompting skills specifically. Fraser told the Washington Post at Davos that AI "will change the nature of what people do every day" and "will take some jobs away." The adaptive training platform lets experts complete the course in under 10 minutes while beginners need about 30 minutes. Citi reported last year that employees had entered more than 6.5 million prompts into its built-in AI tools, and Q4 2025 data shows a 70% adoption rate for the bank's proprietary AI tools.

  • Mozilla is Building an AI 'Rebel Alliance' To Take on Industry Heavweights OpenAI, Anthropic
    by msmash on 27/01/2026 at 8:43 pm

    Mozilla, the nonprofit organization behind the Firefox browser that has spent two decades battling tech giants over control of the internet, is now turning its attention to AI and deploying roughly $1.4 billion in reserves to fund what president Mark Surman calls a "rebel alliance" of startups focused on AI safety, transparency and governance. The organization released a report Tuesday outlining its strategy to counter the growing dominance of OpenAI and Anthropic, which have raised more than $60 billion and $30 billion respectively from investors and now command valuations of $500 billion and $350 billion. Mozilla Ventures, a fund launched in 2022 with an initial $35 million commitment, has invested in more than 55 companies to date and is exploring raising additional capital. Surman, who runs the organization from a farm outside Toronto, acknowledged the financial mismatch but said Mozilla is playing the long game. By 2028, he wants Mozilla to be funding a "mainstream" open-source AI ecosystem for developers. The effort faces headwinds from the Trump administration, which has criticized AI safety efforts as "woke AI" and signed an executive order establishing a task force to challenge state AI regulations.

  • Instagram, Facebook and WhatsApp To Test Premium Subscriptions
    by msmash on 27/01/2026 at 8:02 pm

    An anonymous reader shares a report: Meta plans to test new subscriptions that give people access to exclusive features on its apps, the company told TechCrunch on Monday. The tech giant said the new subscriptions will unlock more productivity and creativity, along with expanded AI capabilities. In the coming months, Meta said it will offer a premium experience on Instagram, Facebook, and WhatsApp that gives users access to special features and more control over how they share and connect, while keeping the core experiences free. Meta doesn't appear to be locked into one strategy, noting that it will test a variety of subscription features and bundles, and that each app subscription will have a distinct set of exclusive features.

  • Android Phones Are Getting More Anti-Theft Features
    by msmash on 27/01/2026 at 7:22 pm

    An anonymous reader shares a report: Google on Tuesday announced an expanded set of Android theft-protection features, designed to make its mobile devices less of a target for criminals. Building on existing tools like Theft Detection Lock, Offline Device Lock, and others introduced in 2024, the newly launched updates include stronger authentication safeguards and enhanced recovery tools, the company said. [...] With the new features, users of Android devices running Android 16 or higher will have more control over the Failed Authentication Lock feature that automatically locks the device after an excessive number of failed login attempts. Now users will have access to a dedicated on/off toggle switch in the device's settings. The devices will also offer stronger protection against a thief trying to guess a device owner's PIN, pattern, or password by increasing the lockout time after failed attempts. Plus, Identity Check, a feature rolled out for Android 15 and higher last year, now covers all features and apps that use biometrics -- like banking apps or the Google Password Manager.

  • France To Ditch US Platforms Microsoft Teams, Zoom For 'Sovereign Platform' Amid Security Concerns
    by msmash on 27/01/2026 at 6:45 pm

    France will replace the American platforms Microsoft Teams and Zoom with its own domestically developed video conferencing platform, which will be used in all government departments by 2027, the country said. From a report: The move is part of France's strategy to stop using foreign software vendors, especially those from the United States, and regain control over critical digital infrastructure. It comes at a crucial moment as France, like Europe, reaches a turning point regarding digital sovereignty. "The aim is to end the use of non-European solutions and guarantee the security and confidentiality of public electronic communications by relying on a powerful and sovereign tool," said David Amiel, minister for the civil service and state reform. On Monday, the government announced it will instead be using the French-made videoconference platform Visio. The platform has been in testing for a year and has around 40,000 users.

  • Microsoft Was Routing Example-Domain Traffic To a Japanese Cable Company for Five Years
    by msmash on 27/01/2026 at 6:01 pm

    Microsoft has quietly suppressed an unexplained anomaly on its network that was routing traffic destined for example.com -- a domain reserved under RFC2606 specifically for testing purposes and not obtainable by any party -- to sei.co.jp, a domain belonging to Japanese electronics cable maker Sumitomo Electric. The misconfiguration meant anyone attempting to set up an Outlook account using an example.com email address could have inadvertently sent test credentials to Sumitomo Electric's servers. Under RFC2606, example.com resolves only to IP addresses assigned to the Internet Assigned Names Authority. Microsoft confirmed it has "updated the service to no longer provide suggested server information for example.com" and said it is investigating. Security researcher Dan Tentler of Phobos Group noted the company appears to have simply removed the problematic endpoint rather than fixing the underlying routing -- "not found" errors now appear where the JSON responses previously occurred. Tinyapps.org, which noted the behavior earlier this month, said the misconfiguration had persisted for five years. Microsoft has not explained how Sumitomo Electric's domain entered its configuration. The incident follows 2024's revelation that a forgotten test account with admin privileges enabled Russia-state hackers to monitor Microsoft executives' email for two months.
