Sharing Sensitive Information Safely
When reporting fraud, you may need to share account details, transaction records, or personal information with authorities. Sending these via plain iMessage or email creates permanent records.
LOCK.PUB lets you create encrypted, password-protected memos that self-destruct after viewing. Share sensitive fraud-related information safely without leaving permanent digital trails.
Quick Reference
| Situation | Action |
|---|---|
| Unknown invoice received | Ignore, don't contact them |
| Already called the number | Hang up, report to authorities |
| Already paid | Contact bank + file reports |
| Unsure if legitimate | Call the company's official number |
The best defense against fake invoices is to never respond to unsolicited payment demands. When you need to share sensitive information securely, use LOCK.PUB.
