To enable conversations between two devices, FIDO2 uses the Client to Authenticator Protocol...

What is a rootkit?

What you need to know about rootkits

If you ask the IT community which malware is the most harmful, the answer is typically not viruses, worms or Trojan horses.

What is DNS Hijacking?

DNS Hijacking: When the Domain Name System becomes a security risk

Technically, the Domain Name System (DNS) is a good thing because it allows you to access a website using its URL rather than its IP address. The domain address is then automatically interpreted as an IP address – thanks to the DNS. But despite these performance benefits, the system carries a significant risk: DNS Hijacking. The practice is simple: a hacker accesses a user’s device configuration...
