The Windows banking trojan known as Coyote has become the first known malware strain to exploit the Windows accessibility framework called UI Automation (UIA) to harvest sensitive information. "The new Coyote variant is targeting Brazilian users, and uses UIA to extract credentials linked to 75 banking institutes' web addresses and cryptocurrency exchanges," Akamai security researcher Tomer Peled said in an analysis. Coyote, first revealed by Kaspersky in 2024, is known for targeting Brazilian users. It comes with capabilities to log keystrokes, capture screenshots, and serve overlays on top of login pages associated with financial enterprises. Part of the Microsoft .NET Framework, UIA is a legitimate feature offered by Microsoft to allow screen readers and other assistive technology products to programmatically access user interface (UI) elements on a desktop.  That UIA can be a potential pathway for abuse, including data theft, was previously demonstrated as a...

Security experts have been talking about Kerberoasting for over a decade, yet this attack continues to evade typical defense methods. Why? It’s because existing detections rely on brittle heuristics and static rules, which don’t hold up for detecting potential attack patterns in highly variable Kerberos traffic. They frequently generate false positives or miss “low-and-slow” attacks altogether.  Is there a better and more accurate way for modern organizations to detect subtle anomalies within irregular Kerberos traffic? The BeyondTrust research team sought to answer this question by combining security research insights with advanced statistics. This article offers a high-level look into the driving forces behind our research and our process of developing and testing a new statistical framework for improving Kerberos anomaly detection accuracy and reducing false positives. An Introduction to Kerberoasting Attacks  Kerberoasting attacks take advantage of the Kerberos netwo...

Google has announced the launch of a new initiative called OSS Rebuild to bolster the security of the open-source package ecosystems and prevent software supply chain attacks. "As supply chain attacks continue to target widely-used dependencies, OSS Rebuild gives security teams powerful data to avoid compromise without burden on upstream maintainers," Matthew Suozzo, Google Open Source Security Team (GOSST), said in a blog post this week. The project aims to provide build provenance for packages across the Python Package Index (Python), npm (JS/TS), and Crates.io (Rust) package registries, with plans to extend it to other open-source software development platforms. With OSS Rebuild, the idea is to leverage a combination of declarative build definitions, build instrumentation, and network monitoring capabilities to produce trustworthy security metadata, which can then be used to validate the package's origin and ensure it has not been tampered with. "Through a...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA), on July 22, 2025, added two Microsoft SharePoint flaws, CVE-2025-49704 and CVE-2025-49706, to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. To that end, Federal Civilian Executive Branch (FCEB) agencies are required to remediate identified vulnerabilities by July 23, 2025. "CISA is aware of active exploitation of a spoofing and RCE vulnerability chain involving CVE-2025-49706 and CVE-2025-49704, enabling unauthorized access to on-premise SharePoint servers," the agency said in an updated advisory. The inclusion of the two shortcomings, a spoofing vulnerability and a remote code execution vulnerability collectively tracked as ToolShell, to the KEV catalog comes after Microsoft revealed that Chinese hacking groups like Linen Typhoon and Violet Typhoon leveraged these flaws to breach on-premises SharePoint servers since July 7, 2025. As of writing, the tech...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added two security flaws impacting SysAid IT support software to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerabilities in question are listed below - CVE-2025-2775 (CVSS score: 9.3) - An improper restriction of XML external entity (XXE) reference vulnerability in the Checkin processing functionality, allowing for administrator account takeover and file read primitives CVE-2025-2776 (CVSS score: 9.3) - An improper restriction of XML external entity (XXE) reference vulnerability in the Server URL processing functionality, allowing for administrator account takeover and file read primitives Both shortcomings were disclosed by watchTowr Labs researchers Sina Kheirkhah and Jake Knott back in May, alongside CVE-2025-2777 (CVSS score: 9.3), a pre-authenticated XXE within the /lshw endpoint. The three vulnerabilities were addressed by SysAid in the on-pre...

Microsoft has formally tied the exploitation of security flaws in internet-facing SharePoint Server instances to two Chinese hacking groups called Linen Typhoon and Violet Typhoon as early as July 7, 2025 , corroborating earlier reports. The tech giant said it also observed a third China-based threat actor, which it tracks as Storm-2603, weaponizing the flaws as well to obtain initial access to target organizations. "With the rapid adoption of these exploits, Microsoft assesses with high confidence that threat actors will continue to integrate them into their attacks against unpatched on-premises SharePoint systems," the tech giant said in a report published today. A brief description of the threat activity clusters is below - Linen Typhoon (aka APT27 , Bronze Union, Emissary Panda, Iodine, Lucky Mouse, Red Phoenix, and UNC215), which is active since 2012 and has been previously attributed to malware families like SysUpdate, HyperBro, and PlugX Violet Typhoon (aka ...
