Most data breaches do not start with sophisticated hacking. They start with someone sharing a file the wrong way. Here are the most common file sharing mistakes and how to avoid them.
Mistake 1: Using "Anyone with the Link" Permissions
Google Drive and Dropbox default to "anyone with the link can view" for shared files. This means anyone who obtains the link (through email forwarding, Slack search, browser history or shoulder surfing) can access the file indefinitely.
Fix: Use a sharing service with password protection and auto-expiry. Password protection guide.
Mistake 2: Sending Passwords in the Same Message
Sending "Here is the file: [link] Password: secret123" in one email means anyone who intercepts or accesses that email has everything they need.
Fix: Send the link via one channel (email) and the password via a different channel (text message or phone call). This two-channel approach means an attacker would need to compromise both channels.
Mistake 3: No Encryption for Sensitive Files
Uploading contracts, tax returns, medical records or financial statements to a sharing service that only uses server-side encryption means the service (and anyone who breaches it) can read your files.
Fix: Enable end-to-end encryption for anything containing personal data. Zero-knowledge encryption ensures nobody except you and the recipient can read the files.
Mistake 4: Files That Never Expire
Shared files that remain accessible for months or years create cumulative risk. Every active share link is a potential entry point for unauthorized access. Old project files, expired contracts and outdated financial statements remain exposed.
Fix: Set expiry dates on all shares. EasySend auto-deletes free uploads after 3 days. For longer needs, the 30-day extension ($0.99) provides a defined window. Expiry options.
Mistake 5: Using Personal Email for Business Files
Employees sharing contracts and client data from personal Gmail accounts bypasses all corporate security controls. Files end up in personal inboxes that may be shared with family members, accessed from unsecured devices or compromised in account breaches.
Fix: Use a business-appropriate sharing method. EasySend requires no corporate account and works from any device while still providing encryption and access controls.
Mistake 6: Trusting ZIP Passwords
ZIP file encryption uses weak algorithms that modern tools crack in seconds. Sending a "password-protected" ZIP is essentially the same as sending an unprotected file.
Fix: Use proper AES-256-GCM encryption. EasySend encrypts in the browser using the Web Crypto API with PBKDF2 key derivation.
Mistake 7: No Download Tracking
Sharing a file and hoping the recipient got it. No confirmation, no audit trail, no way to know if the file was forwarded to unauthorized parties.
Fix: Enable download notifications. Know when files are accessed and follow up if they are not.
Security Checklist
- Is the file sensitive? Enable encryption
- Did you send the password separately from the link?
- Does the share link expire?
- Is download tracking enabled?
- Are you using a business-appropriate tool (not personal email)?
