DNS Hijacking

Definition ∞ DNS Hijacking is a cyberattack where an attacker reroutes internet traffic intended for a legitimate website to a malicious one by altering Domain Name System records. This deception can lead users to fake platforms, enabling the theft of login credentials or digital assets. It represents a significant threat to the integrity of online interactions.
Context ∞ DNS hijacking incidents occasionally affect cryptocurrency platforms, leading to substantial asset losses and erosion of user trust. The situation highlights the critical importance of robust domain security practices, including multi-factor authentication for DNS management. Ongoing efforts focus on strengthening internet infrastructure security and promoting advanced threat detection mechanisms to counter such attacks.
