How a Side Channel Attack Work?
A side-channel attack doesn’t hit the software or its code head-on. Instead, it sneaks around, collecting data or messing with the system’s operation by observing the side effects of its hardware actions. In simpler terms, a side-channel attack cracks security by catching the hints or leaks a system throws off without meaning to.
A famous example is the van Eck phreaking attack, also known as TEMPEST. This method spies on the electromagnetic signals (EMF) that come off a computer screen, grabbing the information displayed before it gets encrypted. This kind of attack is a big deal in the world of cybersecurity, exploiting the electromagnetic leakage from devices to sneak a peek at sensitive data.

What is a Side-Channel Attack? How it Works
Side-Channel Attack: A side-channel attack is a type of cybersecurity threat where the attacker gains information from the physical implementation of a computer system, rather than exploiting software vulnerabilities. This is done by analyzing indirect information, such as power consumption, electromagnetic leaks, or even sound, to uncover sensitive data like cryptographic keys or personal information.
Also, many side-channel analysis techniques have proven successful in breaking an algorithmically robust cryptographic operation and extracting the secret key.
