Hi everyone! I have seen this scary thing on the internet so I am curious about how its effect can be avoided completely?
MANGALORE: As part of strengthening security measures at Kukke Temple Sri Subrahmanya, one of the major pilgrimage centers in southern India, temple authorities have installed a mobile signal jammer.
Inside this surveillance device there are ARM Cortex-A8 computer, which is also called Gumstix, Arduino Nano used for comfortable SPI display control, special LED Bargraph to show the wireless signal level, that is controlled by nice GPIO pin outs made by Overo COM, powerful 802.11 wireless board antenna for network connection, 3.7V battery, 5mm cardioid microphone, 64×32 pixel LCD display that is harvested from the NKK SmartSwitch and MicroSD card with 8Gb memory.
The working principle of this device consists of few phases. First of all it establishes connection with the wireless network nearby, hacking into available websites and stealing server data. After that it must be activated by the user. When Transparency Grenade is activated, the notification of “detonation” will appear on the website at the dedicated server where stolen data was sent. There it will be disassembled to get photos, video- and audio records which would be available online just after any website visitor clicks the “detonation spot” on the map.
