[R] Can machine learning make side-channel attacks even stronger?

I'm a mathematician. Not really into computers and/or hacking. But I wouldn't be surprised if the following is indeed true:

Machine learning can be used to identify activity on your computer from traces recorded in JavaScript that measure CPU instruction throughput over time

But I have a different question. Why would one human being ever try to compromise another human being? By cheating, mistreating, abusing and so on. An irrational and counterproductive behaviour.

side-channel attacks

In short no, just patience, curiosity, and a bit of passion for figuring things out :)

This book (which is out later in the year) looks like it would be a great place to start without a formal background in electronics or computer science: https://nostarch.com/hardwarehacking - it's cowritten by Colin from NewAE (https://wiki.newae.com/Main_Page) which also has tons of information on using the ChipWhisperer for SCA stuff. If you have no embedded systems knowledge at all, start with Arduino, move up to writing some bare C, and then you'll be in a better place to jump in on this sort of material.

Good luck!

r/hacking on Reddit: Resources to learn more about Side-channel attacks?
November 7, 2021 -

For those who don't know here is a neat description of it from the wikipedia:

"In computer security, a side-channel attack is any attack based on information gained from the implementation of a computer system, rather than weaknesses in the implemented algorithm itself (e.g. cryptanalysis and software bugs). Timing information, power consumption, electromagnetic leaks or even sound can provide an extra source of information, which can be exploited."

It looks like a very fascinating branch of studies. I mean break and explore vulnerabilities from radio, electromagnetic leaks, audio, and other things are super groovy.

Also, I am particularly curious about it because I plan to include this as one of the major plot points in a book that I am planing inspired by Gibson, Stephenson, Watts, and Egan. Resumidely my idea is to write about a hacker group operating in the middle of the decade of 2030 composed of transhumanists, occultists, biohackers, and more other unique people. Who decide to migrate from AI-powered spear-phishing and identity theft to other forms of attacks like side-channel vectors. So I am looking to resources to learn more about this type of attack to satisfy my intellectual curiosity, thanks in advance.

What Is a Side-Channel Attack? A Linux Security Overview
November 29, 2025 - Side-channel attacks revolve around the signals a system gives off while it works. These signals are not supposed to reveal anything sensitive, yet they often do when the implementation handles secrets in a way that creates measurable patterns.

However, an eavesdropper observing the side-channel leakage from the encryption process may extract the cryptographic key. When performing an SCA attack, the attacker first collects traces (a collection of side-channel measurements over time while running a known process), often with targeted sensitive data that is constant, while known input or output data may vary between traces.

Side Channel Attacks When Strong Cryptography Enough
1 month ago - Instead, they exploited how modern processors handle data, leaking sensitive information through subtle fluctuations in timing and hardware behavior. These attacks were capable of extracting encryption keys, passwords, and other secrets - even when strong cryptography was in place. This strategic exploitation is a well-known example of what’s called a side channel attack.

December 13, 2024 - The recent Meltdown and Spectre vulnerabilities found in CPUs are notable for many reasons and provide good lessons to everyone. These vulnerabilities exist in the CPU hardware and are a type of sophisticated attack known as a "side-channel attack." Discovered by hardware security experts, these attacks remind us that reliably evaluating the security of modern infrastructure requires a solid understanding of the hardware supporting that infrastructure.
