Phishing is a scam where criminals impersonate known brands (banks, Netflix, government) to steal your data: passwords, cards, bank accounts.

Mechanism: They send you a message (email, WhatsApp, SMS) with a link to a fake page that looks legitimate.

Main red flags:

• Typosquatting: paypa1.com, bank0famerica.com, netfl1x.com
• Suspicious TLD: .tk, .ml, .ga, .cf, .gq (free domains)
• Shortened URL: bit.ly/xyz (hides destination)
• Urgency: "Your account will be suspended in 24h"
• Sensitive data: Asking for password, card, SMS
• No HTTPS: http:// instead of https://
• IP URL: http://192.168.1.1/login

By category:

• Banks: PayPal, Chase, Bank of America, Wells Fargo, Venmo
• Streaming: Netflix, Spotify, Disney+, HBO Max
• Tech: Google, Microsoft, Apple, Amazon
• Government: IRS, Social Security, DMV
• Delivery: FedEx, UPS, Amazon, DoorDash

Modern phishing detectors like Expandir.link use multiple layers of analysis to identify malicious URLs before you click them. Our system combines Machine Learning trained on millions of URLs with real-time checks against 70+ antivirus engines, PhishTank, URLhaus, and ThreatFox databases.

The ML model analyzes 10+ features including URL length, HTTPS presence, IP addresses in domains, typosquatting distance to known brands, suspicious TLDs, and path structure. This allows us to catch approximately 85% of zero-day phishing URLs that haven't been catalogued yet.

📧 Email Phishing

The most common type. Attackers impersonate banks, delivery services, or government agencies. They create urgency: "Your account will be suspended in 24 hours" or "Payment failed — verify now." The links lead to fake login pages that capture your credentials.

📱 SMS & WhatsApp Phishing (Smishing)

Phishing via messaging apps has increased 300% since 2024. Common tactics include fake package delivery notifications, bank alerts, and prize notifications. In Latin America, WhatsApp phishing targeting Daviplata, Nequi, and Bancolombia users is especially prevalent.

🌐 Spear Phishing

Targeted attacks personalized for a specific individual or organization. Attackers research their targets on social media and craft convincing messages that reference real events, colleagues, or projects.

🔗 Typosquatting

Domains that look almost identical to legitimate ones: banc0lombia.com (zero instead of o), d4viplata.com (4 instead of a), paypa1.com (1 instead of l). These domains are registered specifically to trick users who make typing errors.

1. Close the page immediately — Do not enter any information
2. Change your passwords — Use the official app or website, not the phishing link
3. Enable 2FA — Add two-factor authentication to all accounts
4. Contact your bank — Freeze affected cards and report the scam
5. Report the phishing URL — Use Expandir.link's report feature to flag it

Phishing attacks are the number one cybersecurity threat worldwide. In 2025 alone, the FBI received over 300,000 phishing complaints in the United States, with losses exceeding $4.2 billion. Every day, 3.4 billion phishing emails are sent globally, and 36% of recipients who receive them end up clicking the malicious link.

The consequences of falling for a phishing attack can be devastating: stolen bank credentials, identity theft, ransomware infections, and compromised accounts. Recovery can take months and cost thousands of dollars. Detecting phishing before you click is the most effective defense.

Phishing attacks are evolving with new technologies. Stay informed about these emerging threats:

• AI-Generated Content: Attackers now use AI to create flawless phishing emails and messages, eliminating grammar errors and formatting issues that previously revealed scams.
• Deepfakes: AI-generated voice and video that impersonate executives or colleagues, requesting urgent wire transfers or credential sharing.
• Multi-Channel Attacks: Coordinated phishing across email, SMS, and messaging apps simultaneously, increasing perceived legitimacy.
• Supply Chain Phishing: Compromised legitimate services sending phishing messages from official channels, making verification much harder.

Phishing pages often look identical to legitimate websites. Here's what to look for:

• Different domain: The URL in your browser's address bar doesn't match the official website (even minor differences matter)
• Design flaws: Subtle differences in typography, colors, or layout compared to the real site
• Missing features: Navigation links, help pages, or account recovery options may be missing or redirect to other sites
• Unusual requests: Legitimate sites don't ask you to re-enter your full bank details or password via a link
• URL shortener abuse: Links using bit.ly, tinyurl, or cutt.ly hide the real destination
