track phone number | Breaking Cybersecurity News | The Hacker News

Twitter today issued a warning revealing that attackers abused a legitimate functionality on its platform to unauthorizedly determine phone numbers associated with millions of its users' accounts. According to Twitter, the vulnerability resided in one of the APIs that has been designed to make it easier for users to find people they may already know on Twitter by matching phone numbers saved in their contacts with twitter accounts. To be noted, the feature worked precisely as intended, except someone was not supposed to upload millions of randomly generated phone numbers and abuse Twitter to reveal profiles associated with the contact information users added to Twitter for enabling security features. Though the company is not sure if the bug was exploited by only a single adversary or multiple groups, it has identified several accounts engaged in the attack located in a wide range of countries, primarily from Iran, Israel, and Malaysia. Based on their IP addresses, Twitt

Until now, I'm sure you all might have heard of the SimJacker vulnerability disclosed exactly a month ago that affects a wide range of SIM cards and can remotely be exploited to hack into any mobile phone just by sending a specially crafted binary SMS. If you are unaware, the name "SimJacker" has been given to a class of vulnerabilities that resides due to a lack of authentication and proprietary security mechanisms implemented by dynamic SIM toolkits that come embedded in modern SIM cards. Out of many, two such widely used SIM toolkits — S@T Browser technology and Wireless Internet Browser (WIB) — have yet been found vulnerable to SimJacker attacks, details of which we have provided in our previous articles published last month. At that time, a few experts in the telecom industry confirmed The Hacker News that the SimJacker related weaknesses were internally known to many for years, and even researchers also revealed that an unnamed surveillance company has been

As work ebbs with the typical end-of-year slowdown, now is a good time to review user roles and privileges and remove anyone who shouldn't have access as well as trim unnecessary permissions. In addition to saving some unnecessary license fees, a clean user inventory significantly enhances the security of your SaaS applications. From reducing risk to protecting against data leakage, here is how you can start the new year with a clean user list.  How Offboarded Users  Still  Have Access to Your Apps When employees leave a company, they trigger a series of changes to backend systems in their wake. First, they are removed from the company's identity provider (IdP), which kicks off an automated workflow that deactivates their email and removes access to all internal systems. When enterprises use an SSO (single sign-on), these former employees lose access to any online properties – including SaaS applications – that require SSO for login.  However, that doesn't mean that former employee
