Zero-Day Phishing

Definition ∞ Zero-Day Phishing refers to phishing attacks that exploit newly discovered vulnerabilities or employ novel tactics that security systems have not yet identified or patched. These attacks are particularly dangerous because there are no existing defenses or signatures to detect them. Attackers leverage unknown weaknesses to trick users into revealing sensitive information, such as private keys or login credentials. They represent a highly sophisticated and immediate threat.
Context ∞ News in the cybersecurity and crypto space frequently warns about the dangers of zero-day phishing, especially given the high value of digital assets. These attacks often bypass traditional security filters, requiring users to exercise extreme caution and critical thinking. Security researchers and companies work continuously to discover and mitigate these novel threats. Staying informed about the latest attack vectors and practicing robust digital hygiene are essential defenses.
