a16z’s US$1.1 billion Machine Age Fund targets chips, memory, networking, data centres, robotics and power, arguing that AI’s next bottleneck is the physical infrastructure behind the models.
From the UN in New York to a proposed AI campus near Dalby, Australia is seeking a voice in rules and a stake in the infrastructure. Albanese’s diplomatic push raises a practical question: can global ambition deliver local benefits while protecting energy, water and Australia’s digital sovereignty?
Two stories about AI are running, and both are incomplete. The tools genuinely compress work; the accounting, the calibration and the power bills are another matter. Twenty-five years ago the fibre outlasted the forecasts that paid for it, and nothing in a boom is cheaper than a confident number.
One of the largest lead generation datasets ever compiled has been found exposed online, containing 4.3 billion professional records in a 16 terabyte unsecured database.
Cyber News Centre’s cyber update for 15th December 2025: One of the largest lead generation datasets ever compiled has been found exposed online, containing 4.3 billion professional records in a 16 terabyte unsecured database.
The database, believed to belong to a lead generation company, contained professionally scraped and enriched data from sources including LinkedIn and Apollo.io. Lead generation firms compile and sell large scale B2B databases to help businesses find and connect with potential customers.
Update: A 16 terabyte unsecured MongoDB database containing 4.3 billion professional records was discovered exposed on the internet without a password. The dataset, found by security researcher Bob Diachenko in collaboration with nexos.ai on November 23, 2025, was secured two days after the apparent owner was notified. The trove includes nine collections of scraped and enriched data, with at least three containing personally identifiable information on nearly two billion records. Exposed data includes full names, email addresses, phone numbers, LinkedIn URLs, job titles, employers, employment histories, education, locations, skills and in some cases profile photographs.
The database also contained sitemap records linking to a lead generation company’s website, which advertises access to over 700 million professionals, a figure that closely matches the size of one of the database’s collections. The timestamps suggest the data was collected or updated in 2025, making it a fresh and globally relevant dataset. The incident highlights the ongoing risks of unsecured databases and the industrial scale scraping of professional networking platforms for commercial purposes, creating a goldmine for malicious actors.
Why it Matters: This breach provides a ready made blueprint for sophisticated, AI driven social engineering attacks on a global scale, affecting professionals and organisations in Australia and worldwide. With structured data on billions of individuals, malicious actors can automate highly personalised phishing campaigns, business email compromise schemes and CEO fraud with unprecedented efficiency.
The dataset acts as a foundational layer for profile enrichment, allowing criminals to fuse it with other leaked data such as passwords to create comprehensive dossiers for targeted attacks. For Australian businesses, this means a heightened risk of employees being targeted by convincing, context aware scams that reference their specific roles, colleagues and work histories, bypassing traditional security filters.
