Overview of the Incident

A recent report by 404 Media has revealed a significant security breach involving TeleMessage, a platform that offers modified versions of popular encrypted messaging applications like Signal, Telegram, and WhatsApp. This breach has led to the unauthorized extraction of archived messages and sensitive data linked to various U.S. government officials and corporations utilizing the service.

Details of the Breach

TeleMessage, a company based in Israel and owned by Smarsh, garnered attention when it was disclosed that former U.S. National Security Adviser Mike Waltz was using its modified version of Signal for communications. The hacker managed to compromise data that included:

• Archived chat logs and messages
• Contact information of government officials
• Backend login credentials for TeleMessage
• Data pertaining to U.S. Customs and Border Protection, Coinbase, and Scotiabank

While the messages belonging to cabinet members and Waltz remained uncompromised, the overall breach raises significant concerns regarding data security.

Implications of the Breach

Notably, the incident illuminated a critical flaw: the archived chat logs from the modified Signal version are not end-to-end encrypted when transmitted to the storage location managed by TeleMessage. This vulnerability poses a risk for users relying on such modified applications for secure communication.

Responses from Involved Organizations

Requests for comments from Smarsh, Signal, U.S. Customs and Border Protection, Coinbase, and Scotiabank have not received immediate replies, leaving many questions regarding the nature and scope of the breach unanswered.
