Dual SIM Hack For Single SIM Slot Phones.

Posted on by

[RoyTecTips] shows us an ingenious hack which turns a single-SIM-slot phone into a fully functioning dual-SIM phone. All that needed for this hack is a heat-gun, solvent, micro SD card, nano SIM and some glue. The trick is that the phone has a SIM reader on the backside of an SD-card slot. Through some detailed dissection and reconstruction work, you can piggy-back the SIM on the SD card and have them both work at the same time.

Making the SD/SIM Franken-card is no picnic. First you start by filing away the raised bottom edge of the micro SD card and …read more

Every Tornado Siren In Dallas Hacked

Posted on by

Someone had some fun with the Dallas early warning tornado siren system on Friday, April 8th. All 156 tornado sirens were hacked to go off just before midnight until they were manually turned off individually, reports The Washington Post. Thousands of residents flooded 911 call centers asking if they were under attack, if there was a tornado or if the zombie apocalypse had begun. The sirens were blaring for at least an hour and was originally put down as a malfunction, however it was later revealed that it was a hack and the “hacker” must have had physical access to …read more

$10 Orange Pi 2G-IoT Released to Compete With Pi Zero W

Posted on by

A new single-board computer by Orange Pi has popped up for sale on AliExpress. The Orange Pi 2G-IoT is designed to compete with the Raspberry Pi Zero, and if specs are anything to go by they have done a nice job.

There are a lot of options for extra small single board computers these days and there’s a growing list at the lowest price points. Let’s call it the sub-$20 cost range (to quell the argument of shipping fees). We have seen C.H.I.P., the Raspberry Pi Foundation released the Pi Zero W (an update to the Zero line that included …read more

Wirelessly Charge Your Phone From High Voltage Power Lines

Posted on by

Using nothing more than an antenna, a spark plug, a flyback transformer, a diode, and a car phone charger, [Kreosan] have implemented the world’s most dangerous cell-phone charger: wirelessly charging their phone from high voltage power lines. This is a demonstration of a hack that we thought was just an urban legend, but it’s probably best to leave this as just a demo — this one is probably illegal and definitely dangerous.

The charger works by holding an old TV aerial fairly close to high voltage overhead cables, and passing the resulting tiny current through a spark plug and a …read more

Remotely Get Root On Most Smart TVs With Radio Signals

Posted on by

[Rafael Scheel] a security consultant has found that hacking smart TVs takes nothing much more than an inexpensive DVB-T transmitter, The transmitter has to be in range of the target TV and some malicious signals. The hack works by exploiting hybrid broadcast broadband TV signals and widely known about bugs in web browsers commonly run on smart TVs, which seem run in the background almost all the time.

Scheel was commissioned by Cyber security company Oneconsult, to create the exploit which once deployed, gave full root privileges enabling the attacker to setup and SSH into the TV taking complete control …read more

Learn Neural Network and Evolution Theory Fast

Posted on by

[carykh] has a really interesting video series which can give a beginner or a pro a great insight into how neural networks operate and at the same time how evolution works. You may remember his work creating a Bach audio producing neural network, and this series again shows his talent at explaining the complex topic so anyone may understand.

He starts with 1000 “creatures”. Each has an internal clock which acts a bit like a heart beat however does not change speed throughout the creature’s life. Creatures also have nodes which cause friction with the ground but don’t collide with …read more

Gigabytes the Dust with UEFI Vulnerabilities

Posted on by

At this year’s BlackHat Asia security conference, researchers from Cylance disclosed two potentially fatal flaws in the UEFI firmware of Gigabyte BRIX small computers which allow a would-be attacker unfettered low-level access to the computer.

Gigabyte has been working on a fix since the start of 2017. Gigabyte are preparing to release firmware updates as a matter of urgency to only one of the affected models — GB-BSi7H-6500 (firmware vF6), while leaving the — GB-BXi7-5775 (firmware vF2) unpatched as it has reached it’s end of life. We understand that support can’t last forever, but if you sell products with such …read more

Recover Your Broken SD Card Selfies by Your Selfie

You may still have some luck getting those selfies off of your SD card, even if it will no longer mount on your computer. [HDD Recovery Services] shows us a process to directly access the NAND memory of a faulty micro SD card to recover those precious files you thought about backing up but never got around to.

On a Micro SD card you may have noticed there are two slightly longer pins than the rest. These are VSS and VCC pins. As long as they are not a dead short between the two the SD card controller isn’t completely …read more
