This new system keeps your deleted files recoverable for up to 126 days after a cyberattack

When hackers break into your computer, one of the first things they do is delete or lock your files and vanish. By the time you realize something is wrong, the damage is often permanent. A researcher at Florida International University has found a way to change that, and the solution is built right into your storage drive.

When you delete a file, it does not disappear immediately. It sits in a kind of digital purgatory, existing in fragments on your drive before being permanently wiped to free up space.
If a hacker encrypted or erased your data, you could theoretically reach back in and pull those files out before they vanish for good. The problem is that modern SSDs, which power most laptops and computers today, manage this space carelessly.
When the drive needs space, it clears deleted data based purely on efficiency, with no awareness of how recently files were removed. Files deleted during a ransomware attack could get wiped first, while old junk files from weeks ago survive.

The system works by sequencing deleted data by age, so the oldest deleted files go first, and the most recently deleted files stay protected for as long as possible. It also extends the window for recovering deleted data to up to 126 days, improving data protection by at least 60% with minimal impact on drive speed.
Since the storage drive operates independently from your operating system, it can keep protecting your data even after hackers have taken full control of your software. The research is now in active discussions with industry partners about bringing the technology to market.

Android will now warn you if someone is using AI to fake your contact’s voice on a call
Google’s fake call detection is the first time a phone platform has built a real-time cryptographic defense against AI voice cloning scams.
Yes, advancements in AI help people from different walks of life, but they have some cons. One of the most exploited con has been AI voice cloning. Over the years, it has reached the point where most people can no longer tell a deepfake voice from a real one.
Scammers already know this, and they’ve been spoofing users’ contacts, cloning their voice, and committing financial frauds for quite some time. Android’s new fake call detection is designed to stop that exact scenario before it costs you.

Qualcomm’s Snapdragon X2 Elite finally lands in a mini PC, and it looks like Windows’ answer to the Mac mini
For the past two years, Qualcomm’s Snapdragon X series has largely been confined to notebooks. The chips delivered impressive battery life and surprisingly competitive performance, but they never got the chance to challenge compact desktop machines like Apple’s Mac mini or even the more powerful Mac Studio. The Ascent QN10 changes that.
Packing the 18-core Snapdragon X2 Elite processor alongside Qualcomm’s integrated Adreno GPU, the tiny desktop also becomes the world’s first mini PC to offer 80 TOPS of AI performance through its dedicated Hexagon NPU. So, ASUS is introducing a new form factor for Qualcomm’s most powerful PC silicon.

Amazon announces Prime Day sales date and it’s happening a tad earlier this year
Amazon moved Prime Day to June for the first time, quietly positioning it ahead of the back-to-school season.
Amazon Prime Day is back, it is four days long again, and, for the first time in Prime Day’s history, it’s kicking off in June rather than July.
So, if you spent last summer waiting until mid-July to buy that thing at a discounted price, you now have about two fewer weeks to make up your mind.
