Hacking Microsoft Office Outlook | Breaking Cybersecurity News | The Hacker News

A security researcher has won $13,000 bounty from Microsoft for finding a critical flaw in its main authentication system that could allow hackers to gain access to a user's Outlook, Azure and Office accounts. The vulnerability has been uncovered by UK-based security consultant Jack Whitton and is similar to Microsoft's OAuth CSRF (Cross-Site Request Forgery) in Live.com discovered by Synack security researcher Wesley Wineberg. However, the main and only difference between the vulnerabilities is that: Flaw discovered by Wineberg affected Microsoft's OAuth protection mechanism while the one discovered by Whitton affected Microsoft's main authentication system. Microsoft handles authentication across its online services including Outlook, Azure and Office through requests made to login.live.com, login.windows.net, and login.microsoftonline.com. Now, for example, if a user browses to outlook.office.com, he/she redirects to a login.microsoftonline

Following in the footsteps of Twitter, Facebook and Google, Microsoft promises to notify users of its e-mail ( Outlook ) and cloud storage ( OneDrive ) services if government hackers may have targeted their accounts. The company already notifies users if an unauthorized person tries to access their Outlook or OneDrive accounts. But from now on, the company will also inform if it suspects government-sponsored hackers. Ex-Employee: Microsoft Didn't Notify When China Spied Tibetans Leaders The move could be taken in the wake of the claims made by Microsoft's former employees that several years ago Chinese government hacked into more than a thousand Hotmail email accounts of international leaders of Tibetan and Uighur minorities , but the company decided not to tell the victims, allowing the hackers to continue their campaign. Instead of alerting those leaders of the hacking attempts, Microsoft simply recommended them to change their passwords without disclosi

The introduction of Open AI's ChatGPT was a defining moment for the software industry, touching off a GenAI race with its November 2022 release. SaaS vendors are now rushing to upgrade tools with enhanced productivity capabilities that are driven by generative AI. Among a wide range of uses, GenAI tools make it easier for developers to build software, assist sales teams in mundane email writing, help marketers produce unique content at low cost, and enable teams and creatives to brainstorm new ideas.  Recent significant GenAI product launches include Microsoft 365 Copilot, GitHub Copilot, and Salesforce Einstein GPT. Notably, these GenAI tools from leading SaaS providers are paid enhancements, a clear sign that no SaaS provider will want to miss out on cashing in on the GenAI transformation. Google will soon launch its SGE "Search Generative Experience" platform for premium AI-generated summaries rather than a list of websites.  At this pace, it's just a matter of a short time befo

Researchers have unearthed a dangerous backdoor in Microsoft's Outlook Web Application (OWA) that has allowed hackers to steal e-mail authentication credentials from major organizations. The Microsoft Outlook Web Application or OWA is an Internet-facing webmail server that is being deployed in private companies and organisations to provide internal emailing capabilities. Researchers from security vendor Cybereason discovered a suspicious DLL file loaded into the company's OWA server that siphoned decrypted HTTPS server requests. Although the file had the same name as another benign DLL file, the suspicious DLL file was unsigned and loaded from another directory. Hackers Placed Malicious DLL on OWA Server According to the security firm, the attacker replaced the OWAAUTH.dll file ( used by OWA as part of the authentication mechanism ) with one that contained a dangerous backdoor. Since it ran on the OWA server, the backdoored DLL file allowed hacker
