News: What are Acoustic Side Channel
Attacks and how is AI used to increase its accuracy?

●
Acoustic Side Channel Attacks are not new;
however, use of AI deep learning can now be used to crack passwords by
analysing keyboard strokes.
Acoustic
Side Channel Attacks (ASCAs):
●
An
Acoustic Side Channel Attack (ASCA) is a type of cybersecurity attack that exploits sound or acoustic signals to gather
sensitive information.
●
ASCA involves analyzing keyboard clicks to interpret keystrokes
and leak sensitive info.
●
The danger lies in easily available
keyboard sounds and users underestimating their misuse.
●
Users often shield screens when typing
sensitive data, but keystroke sounds remain unprotected.
●
Keyboard click sounds have reduced with
non-mechanical keyboards, but acoustic tech has improved.
●
Laptop usage expands ASCA scope due to
uniform keyboard models aiding AI-enabled interpretation.

Side
Channel Attacks (SCAs):
●
SCAs involve hacking cryptographic algorithms by analyzing auxiliary systems in the
encryption method.
●
These attacks use signals emitted by
devices like electromagnetic waves, power consumption, mobile sensors, and
sounds from keyboards and printers.
●
These signals, once collected, are
interpreted to compromise device security.
