What Is Phishing?
A social engineering attack where an attacker impersonates a trusted entity to trick victims into revealing sensitive information (credentials, financial data) or performing harmful actions (clicking malicious links, downloading malware). Phishing typically occurs via email but also through SMS, phone calls, and fake websites.
In Laravel Applications
Protect your Laravel application's users from phishing by implementing SPF/DKIM/DMARC (preventing email spoofing from your domain), preventing subdomain takeovers (which can host fake login pages), and using HTTPS everywhere.
Example
An attacker takes over an abandoned subdomain (staging.yourapp.com) and creates a fake login page. They send emails from your domain (possible without DMARC) directing users to the fake page.

SPF, DKIM, and DMARC
Three complementary email authentication standards that prevent email spoofing. SPF (Sender Policy Framework) specifies which servers can send email for your domain. DKIM (DomainKeys Identified Mail) adds a cryptographic signature to verify emails were not tampered with. DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receiving servers how to handle emails that fail SPF/DKIM checks.
Subdomain Takeover
A vulnerability where a DNS record (usually a CNAME) points to an external service that is no longer controlled by the domain owner. An attacker can claim the abandoned service and serve their own content on the subdomain, which appears to be part of the legitimate domain.
