WhatsApp’s new document scanning feature is revolutionizing the way we share information, eliminating the need for additional applications that consume storage space. However, cybersecurity specialists warn that This convenience comes with significant risks if not used correctly.
WhatsApp has recently incorporated an integrated document scanner that allows you to digitize physical papers directly from the messaging application. This feature makes it easy to quickly send files without having to download additional software, optimizing device space and streamlining communication.
Despite this technological advantage, digital security experts urgently call for caution. Not all documents should be scanned or shared via messaging platforms, even if they have end-to-end encryption.
Documents that require maximum caution
Specialists have identified 4 main categories of documents that represent a high risk when digitized and shared on WhatsApp:
1) Personal identification documents. This category includes official credentials such as the INE or IFE, passport, birth certificate, CURP, RFC, medical certificates, military records and any document that contains biometric data or sensitive personal information. These files are the main target of cybercriminals to commit identity fraud.
2) Banking and financial information. Purchase receipts, bank statements, credit or debit cards (even if partially hidden), payment receipts, financial records, loan minutes and documents related to monetary movements are especially vulnerable. A single statement can reveal spending patterns, income, and data sufficient to conduct fraudulent transactions.
3) Legal documents. Indictments, judicial promotions, lawsuits, updates on legal procedures and any documentation related to legal processes contain confidential information that It can be used against the people involved or for extortion.
4) Academic and labor archives. School transcripts, institutional credentials, tuition records, professional licenses, payment records, scholarship documents and employment records must also be handled with extreme care, since They can facilitate identity theft in educational or professional contexts.
The real threats behind the scan
WhatsApp, owned by Meta, has identified the main types of fraud associated with the misuse of digitized documents:
* Identity theft: Criminals use the information contained in the documents to impersonate other people and carry out official procedures, apply for credit or commit other types of fraud.
* Fraudulent procedures: With sufficient personal data, fraudsters can initiate legal, administrative or financial procedures that directly affect victims without their knowledge.
* Threats and extortion: Sensitive information becomes a pressure tool to request money or favors through blackmail.
How to protect your documents on WhatsApp
Experts recommend implementing the following security measures when using the WhatsApp scanner:
* Contact verification: Only send sensitive documents to people you absolutely trust. Before sharing information, confirm the recipient’s identity through a call or video call.
* Temporary messages: Turn on the time-limited message feature so that your files are automatically deleted after a set period. This option is found in the settings of each chat.
* Secure backups: Save copies of your important documents in protected channels such as your personal email or encrypted storage apps on your device. This will allow you to delete WhatsApp files immediately after fulfilling its purpose.
* Final elimination: Once the document is no longer needed, delete it completely from both WhatsApp and your phone gallery. Don’t forget to also check the downloaded files folder.
* 2-Step Verification: Set up this additional layer of security in WhatsApp to protect your account from unauthorized access.
* Watermarks: When possible, add a visible mark to the document indicating the date and the specific purpose for which it is being shared.
Document digitization is a powerful tool that facilitates numerous daily procedures, but it requires responsible and informed use. Protecting your personal information is not optional in the digital age; It is a fundamental necessity to preserve your identity and heritage.
