(Zero Hedge)—A San Francisco-based developer discovered that Alibaba Group’s AliExpress marketplace secretly hijacked his computer’s audio system through hidden browser scripts, allowing the website to run inaudible sound waves at zero volume to create “fingerprints” used to track devices without relying on cookies.
The privacy-focused Brave browser revealed in a series of X posts that the AliExpress marketplace was keeping the developer’s computer audio system active through hidden browser scripts, potentially allowing the website to generate a unique identifier for his device.
The issue emerged when the developer’s Bluetooth headphones refused to transfer their audio connection from his computer to his phone while AliExpress was open. A deeper dive of the website’s code showed background scripts maintaining access to the computer’s audio-processing system without producing audible sound.
The scripts allegedly used the browser’s Web Audio API to process signals at zero volume. Small differences in how individual computers handle those signals can be measured and combined into an “audio fingerprint,” allowing websites to recognize devices even when cookies are deleted or blocked.
The developer also found that the scripts collected other device characteristics, including available memory, screen dimensions, and network information.
Here’s what Brave found:
- Alibaba’s AliExpress was caught using users’ audio systems to track them. AliExpress wasn’t recording users but instead playing a silent sound and measuring how users’ specific devices processed it in order to fingerprint them.
- Fingerprinting is a way that websites can identify you without cookies. Sites will note details about your device like your screen size or installed fonts. These details are then combined into a unique, persistent “fingerprint” that can be used to track you across the Web.
- There are slight variations in how each device plays the same audio file due to differences in CPU, sound card, browser, etc. When AliExpress played the silent sound, it measured these small variations to help build fingerprints of users’ devices.
- This tracking was discovered due to an unexpected side effect. A user with Bluetooth headphones noticed they couldn’t play music on their phone because the headphones were instead playing AliExpress’s silent sound from their PC.
Brave turned what it found into a sales pitch for its browser:
- For 6+ years, Brave has protected users against audio fingerprinting, and other fingerprinting types, by default. Brave injects random data into the browser’s output so you show a different fingerprint to different sites. This fingerprint also resets across sessions.
- Trackers are constantly finding new ways to fingerprint your device, so Brave keeps adding new protections. We recently added defenses against GPU fingerprinting, which stops sites from identifying you with your graphics card or drivers.
The findings raise new questions about browser fingerprinting, a stealthy way that uses silent audio processing for covert tracking.
Starting the Day With a Scripture-Inspired Roast Helps Center Your Thoughts on Eternal Truths Amid Temporal Pressures
The world can seem chaotic, especially right after we wake up. Many believers start their mornings reaching for something familiar — a hot cup of coffee — yet end up settling for mediocre brews that do little more than deliver a caffeine jolt. The daily grind of life, with its endless distractions, news cycles, and responsibilities, can leave even the most faithful feeling spiritually parched alongside their physical fatigue. What if your morning ritual could do more than wake you up? What if it could ground you in truth, nourish your body with exceptional quality, and quietly advance a kingdom purpose at the same time?
That’s the promise — and the reality — behind Promised Grounds Coffee. This Christian-founded company doesn’t just roast beans; it approaches every step as an act of worship and discipleship. By selecting only the top 10% of specialty-grade beans, ethically sourced from dedicated farmers in Central and South America, and small-batch roasting them with reverence in Austin, Texas, Promised Grounds delivers what many describe as the best coffee available — never burnt, never bland, but rich with origin stories and layered flavors that honor God’s creation.
From the vibrant Psalm 27 Roast (a light, bright medium option) to the bold yet peaceful 2 Timothy 1:7 Decaf, each bag carries a Scripture verse that turns your daily pour into a gentle reminder of faith. And through their Ounce Per Ounce Promise, every ounce of coffee you enjoy provides an equal ounce of clean water to families in need via partnership with Filter of Hope — literally brewing hope for body and soul, one cup at a time.
The challenge for today’s Christians runs deeper than finding a decent cup. In an age of convenience-driven consumerism, it’s easy to support companies that dilute values or remain silent on matters of faith. Many believers want their everyday choices — from what they drink to how they spend — to reflect discipleship rather than just convenience. Promised Grounds solves this by weaving Christian excellence into the entire process: beans nurtured with prayerful stewardship by farming families, roasted as an offering rather than a commodity, and packaged with Bible verses to encourage a mindset of gratitude and purpose from the first sip. Reviewers consistently praise the smooth, rich profiles — whether enjoyed black in a drip maker, iced on a warm day, or shared in fellowship — noting how the quality stands toe-to-toe with premium secular brands while delivering something far more meaningful.
This integration of faith and flavor addresses a real need in Christian households and ministries. Busy parents, church leaders, and remote workers alike report that starting the day with a Scripture-inspired roast helps center their thoughts on eternal truths amid temporal pressures. The coffee’s exceptional character — bright citrus notes in lighter roasts or deep chocolate undertones in bolder ones — comes from meticulous selection and careful roasting that respects the bean’s natural gifts rather than masking them. It’s the kind of coffee that elevates a simple quiet time, fuels productive workdays, or sparks meaningful conversations when shared at Bible studies or outreach events. And because it’s ethically sourced with integrity, every purchase supports sustainable livelihoods for farmers who treat their crops like family harvests.
For those leading churches or small groups, the impact multiplies. Promised Grounds offers bundles and options perfect for hospitality ministries, turning ordinary coffee service into an opportunity to point people toward the living water of Christ. Imagine greeting visitors with a warm cup whose very bag carries God’s Word — a subtle yet powerful witness that aligns with the Great Commission. The company’s Texas roots and commitment to “brewing hope” resonate especially with believers who value American enterprise paired with global compassion.
Of course, quality alone isn’t enough if the experience feels out of reach. Promised Grounds keeps it accessible with practical perks like free shipping on orders over $40, sample sets for discovering favorites, and thoughtful add-ons such as faith-themed mugs. Whether you prefer whole beans for fresh grinding, grounds for convenience, or even bulk options for larger households and ministries, the result is consistently superior coffee that makes discipleship feel integrated rather than added on.
As you consider how to align even the smallest habits with your walk with God, Promised Grounds Coffee stands out as a refreshing solution. It tackles the dual problems of subpar daily sustenance and disconnected consumption by offering a product that genuinely excels in taste while advancing a mission of clean water, farmer dignity, and scriptural encouragement. Believers who make the switch often describe it as more than a beverage upgrade — it becomes part of their rhythm of gratitude, a daily invitation to remember that every good gift comes from above.
If you’re ready to transform your mornings (and perhaps your church gatherings) with coffee that honors both exceptional craftsmanship and Christian values, I encourage you to explore what Promised Grounds has to offer. One sip at a time, you’ll be nourishing your body, refreshing your spirit, and participating in something far greater — all while enjoying what truly is among the best coffee available.
