30, 2019, Apple temporarily revoked Facebook's Enterprise Developer Program certificates for one day, which caused all of the company's internal iOS apps to become inoperable. Apple stated that "Facebook has been using their membership to distribute a data-collecting app to consumers, which is a clear breach of their agreement with Apple", and that the certificates were revoked "to protect our users and their data". US Senators Mark Warner, Richard Blumenthal, and Ed Markey separately criticized Facebook Research's targeting of teenagers, and promised to sponsor legislation to regulate market research programs. 2010 application privacy breach In 2010, the Wall Street Journal found that many of Facebook's top-rated apps—including apps from Zynga and Lolapps—were transmitting identifying information to "dozens of advertising and Internet tracking companies" like RapLeaf. The apps used an HTTP referer that exposed the user's identity and sometimes their friends' identities. Facebook said that "While knowledge of user ID does not permit access to anyone’s private information on Facebook, we plan to introduce new technical systems that will dramatically limit the sharing of User ID’s". A blog post by a member of Facebook's team further stated that "press reports have exaggerated the implications of sharing a user ID", though still acknowledging that some of the apps were passing the ID in a manner that violated Facebook's policies. 2010 user list In 2010, Canadian security consultant Ron Bowes of Skull Security created a BitTorrent download consisting of the names of about 100 million Facebook users. Facebook likened the information to what is listed in a phone book. It included some who had opted not to be found by search engines, and some who did not realize their information was public. Bowes created the list to get statistical information about user names, which can be used in both penetration testing and computer break-ins. AT&T routing glitch In 2009 and 2010, the fact that Facebook was not requiring connections to use HTTPS other than at login meant that a routing glitch at AT&T caused cookie to end up on the wrong users' phones. This resulted in some Facebook users having continuous access to another person's account instead of their own. Facebook and Cambridge Analytica data scandal In 2018, Facebook admitted that an app made by Global Science Research and Alexandr Kogan, related to Cambridge Analytica, was able in 2014 to harvest personal data of up to 87 million Facebook users without their consent,
