What happens when hackers start attacking at machine speed?

There is something unsettling about receiving a security warning through your letterbox. Emails can be spoofed. Text messages can contain suspicious links.

For anyone running AI agents, this is becoming one of the biggest security risks. As autonomous software begins handling cryptocurrencies, stablecoins, NFTs, and blockchain identities, protecting digital assets becomes just as important as building the agent itself.

AI tools are everywhere, phishing scams are becoming more convincing, and digital assets are worth more than ever. Security isn't simply about keeping your private keys offline anymore.

The recent Tangem laser attack research by Ledger Donjon has sparked discussions across the crypto community, but what does it really mean for everyday users?

If you are new to crypto security, the idea of using a cold wallet can feel a little intimidating. Words like “private keys,” “seed phrases,” and “offline storage” sound technical, and many beginners worry they might press the wrong button and lose everything.
