CISA and NSA Issue Urgent Guidance to Secure WSUS and Microsoft Exchange Servers

CISA and NSA Issue Urgent Guidance to Secure WSUS and Microsoft Exchange Servers

Oct 31, 2025 Vulnerability / Threat Intelligence
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) and National Security Agency (NSA), along with international partners from Australia and Canada, have released guidance to harden on-premise Microsoft Exchange Server instances from potential exploitation. "By restricting administrative access, implementing multi-factor authentication, enforcing strict transport security configurations, and adopting zero trust (ZT) security model principles, organizations can significantly bolster their defenses against potential cyber attacks," CISA said . The agencies said malicious activity aimed at Microsoft Exchange Server continues to take place, with unprotected and misconfigured instances facing the brunt of the attacks. Organizations are advised to decommission end-of-life on-premises or hybrid Exchange servers after transitioning to Microsoft 365. Some of the best practices outlined are listed below - Maintain security updates and patching cadence Migrate end-o...
Emerging Attacker Exploit: Microsoft Cross-Tenant Synchronization

Emerging Attacker Exploit: Microsoft Cross-Tenant Synchronization

Aug 10, 2023 Threat Detection / Attack Signal
Attackers continue to target Microsoft identities to gain access to connected Microsoft applications and federated SaaS applications. Additionally, attackers continue to progress their attacks in these environments, not by exploiting vulnerabilities, but by abusing native Microsoft functionality to achieve their objective. The attacker group Nobelium, linked with the SolarWinds attacks, has been documented using native functionality like the creation of Federated Trusts  [1]  to enable persistent access to a Microsoft tenant. This article demonstrates an additional native functionality that when leveraged by an attacker enables persistent access to a Microsoft cloud tenant and lateral movement capabilities to another tenant. This attack vector enables an attacker operating in a compromised tenant to abuse a misconfigured Cross-Tenant Synchronization (CTS) configuration and gain access to other connected tenants or deploy a rogue CTS configuration to maintain persistence with...
Microsoft Launches Windows Resiliency Initiative to Boost Security and System Integrity

Microsoft Launches Windows Resiliency Initiative to Boost Security and System Integrity

Nov 20, 2024 Endpoint Security / AI Research
Microsoft has announced a new Windows Resiliency Initiative as a way to improve security and reliability, as well as ensure that system integrity is not compromised. The idea, the tech giant said, is to avoid incidents like that of CrowdStrike's earlier this July, enable more apps and users to be run without admin privileges, add controls surrounding the use of unsafe apps and drivers, and offer options to encrypt personal data. One of the most important features is Quick Machine Recovery that's expected to be available to the Windows Insider Program community in early 2025. "This feature will enable IT administrators to execute targeted fixes from Windows Update on PCs, even when machines are unable to boot, without needing physical access to the PC," David Weston, vice president of enterprise and OS security at Microsoft, said . "This remote recovery will unblock your employees from broad issues much faster than what has been possible in the past." ...

Microsoft Releases Fix for Zero-Day Flaw in July 2022 Security Patch Rollout

Microsoft Releases Fix for Zero-Day Flaw in July 2022 Security Patch Rollout

Jul 13, 2022
Microsoft released its monthly round of Patch Tuesday updates to address  84 new security flaws  spanning multiple product categories, counting a zero-day vulnerability that's under active attack in the wild. Of the 84 shortcomings, four are rated Critical, and 80 are rated Important in severity. Also separately resolved by the tech giant are  two other bugs  in the Chromium-based Edge browser, one of which plugs another  zero-day flaw  that Google disclosed as being actively exploited in real-world attacks. Top of the list of this month's updates is  CVE-2022-22047  (CVSS score: 7.8), a case of privilege escalation in the Windows Client Server Runtime Subsystem ( CSRSS ) that could be abused by an attacker to gain SYSTEM permissions. "With this level of access, the attackers are able to disable local services such as Endpoint Detection and Security tools," Kev Breen, director of cyber threat research at Immersive Labs, told The Hacker News.

In cybersecurity, the line between a normal update and a serious incident keeps getting thinner. Systems that once felt reliable are now under pressure from constant change. New AI tools, connected devices, and automated systems quietly create more ways in, often faster than security teams can react. This week's stories show how easily a small mistake or hidden service can turn into a real break-in. Behind the headlines, the pattern is clear. Automation is being used against the people who built it. Attackers reuse existing systems instead of building new ones. They move faster than most organizations can patch or respond. From quiet code flaws to malware that changes while it runs, attacks are focusing less on speed and more on staying hidden and in control. If you're protecting anything connected—developer tools, cloud systems, or internal networks—this edition shows where attacks are going next, not where they used to be. ⚡ Threat of the Week Critical Fortinet Flaw Comes Under...

Power doesn't just disappear in one big breach. It slips away in the small stuff—a patch that's missed, a setting that's wrong, a system no one is watching. Security usually doesn't fail all at once; it breaks slowly, then suddenly. Staying safe isn't about knowing everything—it's about acting fast and clear before problems pile up. Clarity keeps control. Hesitation creates risk. Here are this week's signals—each one pointing to where action matters most. ⚡ Threat of the Week Ghost Tap NFC-Based Mobile Fraud Takes Off — A new Android trojan called PhantomCard has become the latest malware to abuse near-field communication (NFC) to conduct relay attacks for facilitating fraudulent transactions in attacks targeting banking customers in Brazil.
