Why Phishing Still Works in 2025

Phishing succeeds because it targets people, not firewalls. Attackers craft messages that look legitimate, pressure you to act immediately, and route you to fake portals that harvest credentials or push malware. Social media, AI-generated copy, and breached data make lures highly convincing.

Modern Phishing Types

Email Phishing

InvoicingPayrollAccount reset

Fake messages that spoof a brand or colleague and lead to credential theft or wire fraud.

Spear Phishing

Highly targeted messages using personal details (role, project, suppliers) to increase trust.

Smishing (SMS)

Texts claiming package issues, account lockouts, or prize offers with shortened links.

Vishing (Voice)

Phone calls from “IT support” or “bank agents” manipulating you into revealing codes or installing tools.

QRishing (QR codes)

Stickers or images that send you to malicious sites when scanned—common on posters or emails.

Red Flags: How to Spot a Phish

• Sender domain mismatch (e.g., amaz0n-support.com instead of amazon.com).
• Urgent pressure: “Your account will be closed in 1 hour.”
• Unexpected attachments or password-protected zips.
• Link cloaking: button text says one site, hover shows another.
• Generic greeting and grammar inconsistencies.
• Requests for MFA codes or remote-access installs.
• QR codes in emails from unknown sources.

Technical Controls (SPF, DKIM, DMARC, MTA-STS)

SPF — Sender Policy Framework

Publishes which servers can send mail for your domain. Add vendor IPs/services to your SPF record.

DKIM — DomainKeys Identified Mail

Cryptographically signs messages so recipients can verify they weren’t altered and came from your domain.

DMARC — Alignment & Policy

Enforces alignment between From:, SPF, and DKIM. Start with p=none + reporting, then move to p=quarantine and ultimately p=reject.

MTA-STS & TLS Reporting

Forces TLS for mail delivery to your domain and provides visibility when encryption isn’t used.

Bonus Controls

• Secure Email Gateways with URL rewriting, attachment sandboxing, and impersonation detection.
• Conditional access & impossible-travel detection in your identity platform.
• Browser isolation for unknown links and admin accounts.

User Layer: Training & Safe Habits

Humans are your largest attack surface—and strongest defense once trained.

• Quarterly phishing simulations with immediate micro-training.
• Mandatory MFA (app/hardware keys) for email, banking, and admin apps.
• Use passkeys where available; disable SMS-only 2FA.
• Company policy: never share MFA codes; IT never asks for them.
• Report-a-phish button in the mail client to Security/IT.

Helpful Tools & Extensions

Browser Tools

• Password manager with breach alerts (1Password, Bitwarden).
• uBlock Origin or built-in tracking protection.
• HTTPS-Only mode; disable third-party cookies.

Mail & Identity

• Security awareness platform for simulations.
• Identity protection with conditional access and risk-based MFA.
• EDR on endpoints to block malicious payloads if clicked.

Incident Response Playbook (If Someone Clicks)

1. Don’t panic—disconnect the device from the network or enable airplane mode.
2. Change passwords for any accounts that might be exposed; invalidate sessions.
3. Collect evidence: email headers, URLs, time of click, screenshots.
4. Scan and isolate with EDR; check for persistence or suspicious processes.
5. Reset tokens: revoke OAuth app grants and refresh API keys if relevant.
6. Notify stakeholders and, if needed, customers per policy/regulation.
7. Lessons learned: update filters, run targeted training, tune DMARC policy.

7-Day Rollout Plan

• Day 1: Enable MFA for mail & critical apps. Publish SPF.
• Day 2: Configure DKIM for outbound mail.
• Day 3: Start DMARC with p=none and aggregate reports.
• Day 4: Deploy report-a-phish button + awareness refresher.
• Day 5: Roll out EDR and browser protections.
• Day 6: Move DMARC to p=quarantine; tune false positives.
• Day 7: Enforce p=reject and enable MTA-STS/TLS-RPT.

FAQ

Are QR codes safe?

Only scan codes you trust. Prefer opening your bank/portal from a saved bookmark instead.

Is SMS 2FA enough?

It’s better than nothing, but app-based codes or hardware keys are much stronger.

What’s the ideal DMARC policy?

Phase in: p=none → p=quarantine → p=reject once alignment is stable.

Conclusion

Phishing isn’t going away, but its impact can be minimized. Authenticate your domain, harden endpoints, train your people, and prepare a fast incident response. Make it easy to report suspicious messages, and keep improving based on real attempts targeting your organization.
