Why You Should Be Careful with PDF Attachments

Every day, people receive countless PDFs by email — invoices, job applications, delivery confirmations, even official-looking forms. Unfortunately, not all of them are safe. Cybercriminals often disguise phishing attacks inside these files, tricking users into opening documents that lead to malicious websites.

While modern PDF readers are more secure than ever, they can still expose you to phishing links or QR codes that redirect to fraudulent pages. That’s where Seguradoc comes in.

The Hidden Risk Behind “Simple” PDF Files

Many phishing emails use PDFs that appear legitimate but include fake login pages, embedded links, or deceptive QR codes. Clicking or scanning these can lead to stolen passwords, financial loss, or compromised accounts.

Even if the file itself doesn’t contain executable code, it can still put your data at risk. The safest way to view a suspicious PDF is to never open it directly on your device.

How to Safely View PDFs with Seguradoc

Seguradoc allows you to see what’s inside a PDF file without ever opening it on your computer or phone.
Here’s how it works:

Sandbox isolation – When you upload a PDF, Seguradoc opens it inside a secure sandbox environment, completely isolated from your device.
Snapshot generation – The system converts every page into static image snapshots, ensuring no embedded scripts or interactive content can run.
Sanitized file creation – Seguradoc rebuilds a clean version of the file using only these images, giving you a safe PDF that can be downloaded or shared.
Phishing & QR scan – Any visible links or QR codes are checked for potential phishing threats before being displayed.
AI-generated summary – To save you time, Seguradoc analyzes the content and provides an automatic text summary of the document.

Because the original file never leaves the sandbox, you can safely inspect its content without risk.

Protecting Your Privacy

All uploaded files are automatically deleted after 24 hours, ensuring that nothing stays stored longer than necessary. Seguradoc doesn’t train AI models on user data, doesn’t share uploads, and doesn’t retain any personal information.

Your privacy and file security come first.

Final Thoughts

Phishing attacks are getting smarter, and PDF files are one of their favorite tools.
Instead of taking risks by opening attachments directly, you can use Seguradoc to safely preview, analyze, and summarize any PDF in seconds.

Next time you receive an unexpected attachment, upload it to Seguradoc — and see what’s really inside, safely.
