In this episode, we continue with a closer look at what cybersecurity competence actually means, and why qualifications, compliance frameworks, and public reputation are poor substitutes for understanding how real attacks work. We explore the cryptography behind Proton Mail, public and private keys, fingerprints, and what you can do with PGP word lists. We’ll also discuss passkeys, account recovery, SIM swaps, ClickFix malware, infostealers, VPN blocking, and the residential proxies that allow malicious traffic to hide behind ordinary household IP addresses.
In this week’s episode:
- Hackers, threat actors, security influencers, and the risks created by confident but inaccurate advice
- Kerckhoffs’s principle: designing security under the assumption that the enemy knows the system
- How public and private keys work, including Proton Mail encryption, digital signatures, fingerprints, and independent key verification
- Using the PsySecure Workbench and PGP word lists to make cryptographic fingerprints easier to exchange and verify
- The problem with passkeys, and why weak account recovery can undermine their security
- ClickFix attacks that imitate Cloudflare verification pages and trick users into running malicious terminal commands
- How infostealers target browser data, authenticated sessions, cookies, passwords, and other valuable information
- Why VPN traffic is increasingly blocked or challenged while attackers move toward residential proxies that resemble legitimate users
- You are the proxy: How cheap smart home devices, streaming boxes, thermostats, and cameras, can become hidden residential proxies
- The normalization of identity verification, digital ID checks, and other invasive systems
