What is the Signal messaging app and how secure is it?
Briefly

The messaging app Signal has gained notoriety after being used for a secret group chat among senior US officials, which inadvertently included Atlantic editor Jeffrey Goldberg. The discussion centered on military plans against the Houthi group in Yemen, provoking significant backlash, particularly from political figures like Senate leader Chuck Schumer, who decried it as a major military intelligence leak. Signal is known for its robust security measures, especially end-to-end encryption, and its open-source code, making it attractive to cybersecurity experts.
Signal's security features extend beyond E2EE, being open source to allow public scrutiny for vulnerabilities, which secures its users' communications more effectively.
Senate leader Chuck Schumer described the Signal group chat leak as 'one of the most stunning' military intelligence leaks ever, prompting calls for an investigation.
Signal is owned by a non-profit and collects significantly less user data, which enhances its appeal among those prioritizing privacy.
Signal's emphasis on privacy and security establishes it as the 'gold standard in private communications' as stated by its CEO, Meredith Whittaker.
