An unnamed Federal Civilian Executive Branch (FCEB) agency in the U.S. detected anomalous email activity in mid-June 2023, leading to Microsoft's discovery of a new China-linked  espionage campaign  targeting two dozen organizations. The details come from a joint cybersecurity advisory released by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and Federal Bureau of Investigation (FBI) on July 12, 2023. "In June 2023, a Federal Civilian Executive Branch (FCEB) agency identified suspicious activity in their Microsoft 365 (M365) cloud environment," the authorities  said . "Microsoft determined that advanced persistent threat (APT) actors accessed and exfiltrated unclassified Exchange Online Outlook data." While the name of the government agency was not revealed,  CNN  and  the Washington Post  reported it was the U.S. State Department, citing people familiar with the matter. Also targeted were the Commerce Department as well as the e...

Microsoft has  released emergency patches  to address four previously undisclosed security flaws in Exchange Server that it says are being actively exploited by a new Chinese state-sponsored threat actor with the goal of perpetrating data theft. Describing the attacks as "limited and targeted," Microsoft Threat Intelligence Center (MSTIC) said the adversary used these vulnerabilities to access on-premises Exchange servers, in turn granting access to email accounts and paving the way for the installation of additional malware to facilitate long-term access to victim environments. The tech giant primarily attributed the campaign with high confidence to a threat actor it calls HAFNIUM, a state-sponsored hacker collective operating out of China, although it suspects other groups may also be involved. Discussing the tactics, techniques, and procedures (TTPs) of the group for the first time, Microsoft paints HAFNIUM as a "highly skilled and sophisticated actor" that m...

In recent years, artificial intelligence (AI) has begun revolutionizing Identity Access Management (IAM), reshaping how cybersecurity is approached in this crucial field. Leveraging AI in IAM is about tapping into its analytical capabilities to monitor access patterns and identify anomalies that could signal a potential security breach. The focus has expanded beyond merely managing human identities — now, autonomous systems, APIs, and connected devices also fall within the realm of AI-driven IAM, creating a dynamic security ecosystem that adapts and evolves in response to sophisticated cyber threats. The Role of AI and Machine Learning in IAM AI and machine learning (ML) are creating a more robust, proactive IAM system that continuously learns from the environment to enhance security. Let's explore how AI impacts key IAM components: Intelligent Monitoring and Anomaly Detection AI enables continuous monitoring of both human and non-human identities , including APIs, service acc...
