Signal head defends messaging app’s security after Houthi attack text…

Meredith Whittaker, president of Signal, stated that the app is the “gold standard in private comms” in a post on X, emphasizing its security advantages over WhatsApp. Signal is open-source and nonprofit, focusing on end-to-end encryption and privacy. US downloads of Signal increased by 16% in the first quarter of 2025 compared to the previous quarter, and by 25% year-over-year. Whittaker highlighted that WhatsApp collects metadata, which can reveal communication patterns, while Signal collects very little user data. A WhatsApp spokesperson defended the platform's use of metadata for spam prevention and service integrity, stating they do not track personal messages for advertising.

Signal is ‘as safe as messaging apps get’, but not for national security

End-to-end encrypted messaging app Signal is recognized for its security features but is advised against for use by government officials discussing national security. A breach occurred when members of former President Donald Trump's national security team mistakenly included a journalist in a group chat sharing sensitive military information. Cybersecurity experts express concerns about the potential legal implications of using apps like Signal for classified communications, as it could violate the Espionage Act. High-ranking officials were involved in this incident, which exposed sensitive details, including air-strike targets and the identity of a CIA officer. Typically, government officials use Secure Compartmentalized Information Facilities (SCIFs) for classified information, and there are specific government-approved systems for transmitting such information that do not include Signal.

What is Signal? The app where US officials accidentally shared war plans with a journalist

A group chat among top US officials on the secure messaging app Signal inadvertently included a journalist, raising concerns about the app's security and the protocols for its use by government officials. Signal is known for its end-to-end encryption, ensuring that only participants can access conversations, and it cannot comply with law enforcement requests for user data. During the Biden administration, officials were allowed to use Signal under strict instructions not to share classified information. The incident involving Trump administration officials, who mistakenly added a journalist to a chat about military operations, is being reviewed by the National Security Council.

What is messaging app Signal and how secure is it?

Signal was used for a secret group chat among senior U.S. officials, which included discussions about a military strike against the Houthi group in Yemen. This incident was revealed when Jeffrey Goldberg, editor-in-chief of the Atlantic, was inadvertently included in the chat. Senate Majority Leader Chuck Schumer criticized the leak as "one of the most stunning" in military intelligence history and called for an investigation. Signal has an estimated 40 to 70 million monthly users and is known for its end-to-end encryption, which ensures message privacy. However, experts warn that using Signal for sensitive national security discussions is unusual, as such conversations typically occur on secure government systems. There are concerns about potential legal issues with disappearing messages on Signal, particularly regarding official record-keeping. The ongoing debate over end-to-end encryption has seen companies like Signal resist governmental attempts to create backdoors for monitoring communications.
