The database, which has been pulled down, wasn&#8217;t protected by a password or any other safeguard. Access to the database was removed, but by then the information had been out in the open for nearly two weeks. Someone had also made the data available for download on a hacker forum, according to&nbsp;<a href=\"https:\/\/www.comparitech.com\/blog\/information-security\/267-million-phone-numbers-exposed-online\/\" rel=\"noopener noreferrer nofollow\" target=\"_blank\">Comparitech<\/a>, a UK technology research firm that worked with Diachenko.&nbsp;<\/p>\n<p>Facebook&#8217;s latest privacy mishaps raises questions about whether the company is doing enough to protect the data of its billions of users. It&#8217;s also another reminder that users should be wary about what information they make public on the social network. This isn&#8217;t the first time a security researcher has uncovered a database filled with Facebook user data. The revelation also comes after UK political consultancy <span class=\"link\" section=\"shortcodeLink\"><a href=\"https:\/\/www.cnet.com\/news\/facebook-cambridge-analytica-data-mining-and-trump-what-you-need-to-know\/\">Cambridge Analytica<\/a><\/span> harvested the data of up to 87 million Facebook users without their consent.&nbsp;<span class=\"link\" section=\"shortcodeLink\"><a href=\"https:\/\/www.cnet.com\/news\/facebook-found-millions-of-passwords-stored-in-plain-text-in-internal-investigation\/\">Facebook<\/a><\/span>&nbsp;has faced other privacy woes such as storing hundreds of millions of passwords in plain text.&nbsp;<\/p>\n<p>Comparitech said the exposed Facebook data puts users at risk for spam and phishing campaigns. A Facebook user ID contains unique numbers that can be used to figure out a person&#8217;s Facebook username and other profile information.&nbsp;<\/p>\n<p>Diachenko thinks that criminals in Vietnam obtained the user records through two possible ways. They could have exploited Facebook&#8217;s application programming interface, or API, that lets developers access data such as their friends list, photos and groups. This might have happened before Facebook restricted access to user phone numbers in 2018 or afterward because of a possible security hole. Criminals could have also used automated technology to scrape the information from public Facebook profiles.&nbsp;<\/p>\n<p>In an email, Diachenko said that a welcome page and dashboard linked to the database included a Vietnamese invitation asking for a login and password. It appears that the database was set to public by mistake because &#8220;there are no good reasons to publicly expose this data,&#8221; he said.<\/p>\n<p>A Facebook spokesman said in a statement that the company is looking into the issue but thinks the data was likely harvested before it made changes to better safeguard user information such as restricting access to phone numbers.<\/p>\n<p>To help protect your Facebook data from getting scraped, you can change your privacy settings so search engines outside of Facebook can&#8217;t link to your profile. You can also deactivate or delete your Facebook account.<\/p>\n<p>Unprotected public databases have been a problem for Facebook. In April, security researchers from <span class=\"link\" section=\"shortcodeLink\"><a href=\"https:\/\/www.cnet.com\/news\/millions-of-facebook-records-were-exposed-on-public-amazon-server\/\">UpGuard<\/a><\/span> found more than 540 million Facebook user records, including comments and likes, in a public database on Amazon&#8217;s cloud servers. In September, <a href=\"https:\/\/techcrunch.com\/2019\/09\/04\/facebook-phone-numbers-exposed\/\" rel=\"noopener noreferrer nofollow\" target=\"_blank\">TechCrunch<\/a> reported on a server that contained several databases filled with more than 419 million Facebook records from users in the US, UK and Vietnam. Facebook, though, said the server contained roughly 220 million records. The latest exposed database included similar Facebook user data but it&#8217;s not the same, Diachenko said.&nbsp;<\/p>\n<p>In September, another <span class=\"link\" section=\"shortcodeLink\"><a href=\"https:\/\/www.cnet.com\/news\/facebook-user-phone-numbers-still-online\/\">security researcher<\/a><\/span> found a similar database with Facebook user data. It&#8217;s unclear if the same person or group is posting Facebook user information online.<\/p>\n<div class=\"shortcode video v2\"
