That has won it more trust with those concerned about privacy.<\/p>\n<p>Signal also goes further than WhatsApp on data privacy, making metadata such as when the message was delivered and its recipient invisible even to the company itself.<\/p>\n<p>And WhatsApp shares information with its parent company Meta and third parties, including phone numbers, mobile device information, and IP addresses.<\/p>\n<p>For these reasons, Signal has long been a go-to messaging service for users particularly concerned about communications secrecy, such as people working in security professions, journalists, and their sources.<\/p>\n<p>\u2013 Who owns Signal? \u2013<\/p>\n<p>Founded in 2012, Signal is owned by the Mountain View, California-based Signal Foundation.\u00a0<\/p>\n<p>Its history is linked to WhatsApp: the site was founded by cryptographer and entrepreneur Moxie Marlinspike, with an initial $50 million from WhatsApp co-founder Brian Acton.<\/p>\n<p>Both Signal and WhatsApp, which was bought by Mark Zuckerberg in 2014, are based on the same protocol built by Marlinspike.<\/p>\n<p>\u201cWe\u2019re not tied to any major tech companies, and we can never be acquired by one either,\u201d Signal\u2019s website reads. Development is mainly supported by grants and donations.<\/p>\n<p>Very outspoken compared to other Silicon Valley bosses, Signal\u2019s president is Meredith Whittaker, who spent years working for Google and is a fierce critic of business models built on the extraction of personal data.<\/p>\n<p>\u2013 Was Signal hacked? \u2013<\/p>\n<p>Signal\u2019s encryption itself has not been broken.\u00a0<\/p>\n<p>Cyberattackers accused of Russian links did not target the encryption system directly.<\/p>\n<p>Instead, recent attacks relied on phishing \u2014 tricking users into handing over access to their accounts.<\/p>\n<p>The attacks work by sending messages purporting to come from Signal support, like fake security alerts or invites to join group chats.\u00a0<\/p>\n<p>Once users click on these links or enter sensitive account information, attackers can then gain access to messages and chat groups.\u00a0<\/p>\n<p>This means hackers gain access to data shared on Signal and can also impersonate the person whose account was compromised.<\/p>\n<p>Signal did not immediately respond to requests for comment on the recent attacks. \u00a0<\/p>\n<\/p><\/div>\n<p><!-- \u603b\u5bb9\u5668\uff1a\u6700\u5927\u5bbd908px Grid\u7d27\u51d1\u5e03\u5c40 -->\r\n<div style=\"display: grid;
