Signal app fights spam in new ways

The Signal instant messaging application seeks to make the inquiries received by the user from people who are not registered in his contacts more secure, as the profile picture of the senders who are not registered in the phone book will remain anonymous and unrecognizable, until the user clicks on it.

The company, Open Whisper Systems, which developed the Signal application, aims to prevent the user from responding to those who post attractive or misleading images in the profiles, such as placing the image of the bank the user is dealing with, and thus engaging in a conversation that leads to fraud incidents.

For the same reason, Internet addresses will no longer be shown in message queries, which are sometimes used to direct the user to fake websites or be subjected to phishing attacks.

Efforts are not limited to preventing intrusion in individual messages and conversations, but the company also aims to prevent it in the entire instant messaging network, where the user will have the ability to block and report such inquiries, and in this way the Signal application can identify spam campaigns ) early and removed.

Given the high demand for the use of Signal in 2021, this platform has become a target for hackers and scammers, and the service has confirmed that addressing spam is done without analyzing the contents of messages or relationships between users of the instant messaging application.

If the user clicks “Report and block spam”, the phone number of the sender of the anonymous spam will be sent to the Signal service.

If the phone number is reported repeatedly, or appears to be sending spam automatically, it will be asked to solve a CAPTCHA puzzle to slow down the automatic spam campaign.

Through these new procedures, the American company will open new horizons for dealing with spam messages, and a separate domain will be allocated to it in the server.
