Azure Active Directory | Breaking Cybersecurity News | The Hacker News

Microsoft on Friday said a validation error in its source code allowed for Azure Active Directory (Azure AD) tokens to be forged by a malicious actor known as  Storm-0558  using a Microsoft account (MSA) consumer signing key to breach two dozen organizations. "Storm-0558 acquired an inactive MSA consumer signing key and used it to forge authentication tokens for Azure AD enterprise and MSA consumer to access OWA and Outlook.com," the tech giant  said  in a deeper analysis of the campaign. "The method by which the actor acquired the key is a matter of ongoing investigation." "Though the key was intended only for MSA accounts, a validation issue allowed this key to be trusted for signing Azure AD tokens. This issue has been corrected." It's not immediately clear if the token validation issue was exploited as a "zero-day vulnerability" or if Microsoft was already aware of the problem before it came under in-the-wild abuse. The attacks singl...

Microsoft has patched a misconfiguration issue impacting the Azure Active Directory ( AAD ) identity and access management service that exposed several "high-impact" applications to unauthorized access. "One of these apps is a content management system (CMS) that powers Bing.com and allowed us to not only modify search results, but also launch high-impact XSS attacks on Bing users," cloud security firm Wiz  said  in a report. "Those attacks could compromise users' personal data, including Outlook emails and SharePoint documents." The issues were reported to Microsoft in January and February 2022, following which the tech giant applied fixes and awarded Wiz a $40,000 bug bounty. Redmond  said  it found no evidence that the misconfigurations were exploited in the wild. The crux of the vulnerability stems from what's called "Shared Responsibility confusion," wherein an Azure app can be incorrectly configured to allow users from any Micro...

It's time once again to pay our respects to the once-famous cybersecurity solutions whose usefulness died in the past year. The cybercriminal world collectively mourns the loss of these solutions and the easy access they provide to victim organizations. These solutions, though celebrated in their prime, succumbed to the twin forces of time and advancing threats. Much like a tribute to celebrities lost in the past year, this article will look back at a few of cybersecurity's brightest stars that went dark in the past year.  1. Legacy Multi-Factor Authentication (MFA) Cause of Death: Compromised by sophisticated phishing, man-in-the-middle (MitM), SIM-swapping, and MFA prompt bombing attacks. The superstar of access security for more than twenty years, legacy MFA solutions enjoyed broad adoption followed by almost-universal responsibility for cybersecurity failures leading to successful ransomware attacks. These outdated solutions relied heavily on SMS or email-based codes o...
