DiskFiltration: You think your data is safe because o computer σας δεν είναι συνδεδεμένος στο Internet ή σε κάποιο network; Λάθος!
As they recently proved researchers security, the sounds of your computer's hard drive can be used to transmit data over the air even from a seemingly well-protected system.
DiskFiltration hack, proven by video at the end of publication by security researcher Mordechai Guri of Ben-Gurion University in Israel, works by controlling the hard disk drive actuator as it moves the platters back and forth to read and write data.
Think of it as an arm of the turntable, which however moves back and forth continuously at terrifying speeds.
As the actuator moves, it produces small sounds. Do you know the sounds when you start a computer?
Some of this noise comes from the machine's hard drive, and with the right malware installed, these sounds can leak sensitive data out of the air, to a nearby device, such as a smartphone.
Το DiskFiltration έχει εμβέλεια λειτουργίας περίπου two meters, but is limited to a slow data rate of around 180 bits per minute. The speed, although low, is enough to "catch" a complex encryption key, say 4096-bit RSA, in about 25 minutes. The method does not work with SSDs that have no moving parts.
